The present disclosure relates to the field of communications technologies, and in particular, to a multi-carrier measurement configuration method and apparatus.
In a communications system, a larger transmission bandwidth is an important factor of improving a data transmission rate in the system. Therefore, to increase a transmission bandwidth, a carrier aggregation (CA) technology is put forward. Carrier aggregation is to aggregate at least two carriers to support a larger transmission bandwidth.
Before performing carrier aggregation, user equipment (UE) needs to select, from multiple to-be-aggregated candidate carriers by using a measurement result, a specified quantity of carriers for carrier aggregation. Therefore, the UE needs to measure each to-be-aggregated candidate carrier. Currently, in a Long Term Evolution (LTE) system, a gap measurement manner is usually used to measure carriers of adjacent frequencies.
For example, if UE working in a cell 1 whose corresponding carrier frequency is P1 needs to measure a carrier frequency P2 that corresponds to an adjacent cell 2, the UE may adjust, within a time of a gap configured by a network side for the UE, a receiver of the UE to the frequency P2 for measurement, and the receiver returns to P1 after the time of the gap expires, to normally receive data. Within the time of the gap, the UE cannot receive data sent by the cell 1 corresponding to P1. Currently, in the LTE system, a gap configuration manner that is usually used is to configure a gap measurement time of 6 ms in a period of 40 ms or 80 ms.
The UE may further use a small gap measurement manner to measure carriers of adjacent frequencies. For example, when the UE has at least two radio frequencies (RF), the UE uses one of the RFs to receive data in a current cell, and uses the other RF as a measurement RF to measure carriers of adjacent frequencies. However, when the measurement RF is enabled, disabled, or adjusting a frequency, the RF used to receive data in the current cell also cannot normally receive data. That is, when the measurement RF measures a carrier within a measurement time of 6 ms, the RF used to receive data in the current cell cannot receive data within the starting 1 ms and the ending 1 ms, but can receive data within the intermediate 4 ms. Generally, a time, for example, the starting 1 ms or the ending 1 ms, within which data cannot be received is referred to as a small gap.
Currently, because in the existing gap measurement manner and small gap measurement manner, only a specified and fixed mode in the prior art can be used, a carrier measurement manner in the prior art cannot be configured, applicability is relatively low, and carrier aggregation efficiency of UE is reduced.

By means of the technical solutions of the present disclosure, UE receives a measurement configuration message that is sent by a network side and that includes gap measurement configuration information and/or small gap measurement configuration information, and measures multiple carriers according to the measurement configuration message, so as to implement configuration of a carrier measurement manner by the network side, thereby improving applicability of carrier measurement, and improving carrier aggregation efficiency of the UE.
To make the objectives, technical solutions, and advantages of the present disclosure clearer, the following further describes the present disclosure in detail with reference to the accompanying drawings. Apparently, the described embodiments are merely a part rather than all of the embodiments of the present disclosure. All other embodiments obtained by persons of ordinary skill in the art based on the embodiments of the present disclosure without creative efforts shall fall within the protection scope of the present disclosure.
The embodiments of the present disclosure provide a multi-carrier measurement configuration method and apparatus, so as to resolve a problem in the prior art that when UE aggregates multiple carriers, a carrier measurement manner cannot be configured, applicability is relatively low, and carrier aggregation efficiency of the UE is reduced. The method and the apparatus are based on a same inventive concept. Because the principles for resolving problems of the method and the apparatus are similar, implementations of the apparatus and the method can be cross-referenced. No repeated description is provided.
By means of the multi-carrier measurement configuration method provided in the present disclosure, UE receives a measurement configuration message that is delivered by a network side and that carries gap measurement configuration information or small gap measurement configuration information, and measures multiple carriers based on a received processing configuration message, so as to implement configuration of a carrier measurement manner by the network side, thereby improving applicability of carrier measurement, and improving carrier aggregation efficiency of the UE.
An embodiment of the present disclosure further provides a multi-carrier measurement configuration method, applied to a terminal device that can perform carrier measurement. Referring to
Step 101: UE receives a measurement configuration message sent by a network side, where the measurement configuration message includes gap measurement configuration information and/or small gap measurement configuration information.
Specifically, the UE receives, by using Media Access Control (MAC) signaling or physical downlink control channel (PDCCH) signaling or Radio Resource Control (RRC) signaling, a measurement configuration message that is delivered by the network side and that carries gap measurement configuration information or small gap measurement configuration information.
The small gap measurement configuration information includes any one or a combination of the following: a small gap measurement period, a small gap measurement quantity, small gap duration, an offset value, or a length of a time interval between two adjacent small gaps; or
the small gap measurement configuration information includes three consecutive small gaps.
When the small gap measurement configuration information includes three consecutive small gaps, measuring, by the UE, a carrier according to the measurement configuration message includes: consecutively measuring, by a radio frequency link of the UE, two carriers according to the three small gaps.
The gap measurement configuration information includes at least first gap measurement configuration information and second gap measurement configuration information, where each piece of gap measurement configuration information includes one or a combination of the following: a gap measurement period, a gap measurement quantity, gap duration, an offset value, or a length of a time interval between two adjacent gaps. Generally, different gap measurement configuration information may have different quantities of parameters, and a same parameter may have different values. In two pieces of gap measurement configuration information, at least one configuration parameter has different values.
When gap measurement configuration information carried in measurement configuration information delivered by the network side includes at least two types of gap measurement configuration information, measuring, by the UE, a carrier according to the measurement configuration message includes: determining, by the UE according to an indication message sent by the network side, to use first gap measurement configuration information or second gap measurement configuration information to measure a carrier.
Specifically, the determining, by the UE according to an indication message sent by the network side, to use first gap measurement configuration information or second gap measurement configuration information to measure a carrier includes:
receiving, by the UE, a gap measurement mode identifier that is delivered by the network side by using MAC signaling or PDCCH signaling, where
the gap measurement mode identifier corresponds to one type of gap measurement configuration information (the first gap measurement configuration information or the second gap measurement configuration information); and
measuring, by the UE, multiple carriers according to the gap measurement configuration information that corresponds to the gap measurement mode identifier.
Optionally, the gap measurement configuration information includes at least gap duration information. Preferably, the gap duration information includes 10 milliseconds, 11 milliseconds, or 12 milliseconds.
When the gap measurement configuration information includes at least gap duration information, and the gap duration information includes 10 milliseconds, 11 milliseconds, or 12 milliseconds, the measuring, by the UE, a carrier according to the measurement configuration message includes: measuring, by the UE, at least two carriers in a gap indicated by the gap duration information.
Currently, in the existing gap measurement manner, one candidate carrier may be measured in each period. If multiple carriers need to be measured, apparently, the UE needs to take a relatively long time to perform carrier measurement, and after the measurement, an already measured candidate carrier may have already changed. This reduces carrier aggregation efficiency of the UE. By means of setting the gap duration information to 10 milliseconds, 11 milliseconds, or 12 milliseconds, the UE can measure at least two carriers in one gap, and when consecutively measuring carriers, the UE can directly jump from measurement of a carrier whose frequency is P1 to measurement of a carrier whose frequency is P2. In this way, a process of returning to an operating frequency is reduced, that is, in one gap measurement period, at least two carriers can be measured. Compared with the prior art in which only one carrier can be measured in one gap measurement period, carrier measurement efficiency of the UE is improved.
Optionally, before step 101 is performed, the method further includes:
sending, by the UE, a measurement capability message to the network side, where the measurement capability message includes small gap-based measurement capability information and/or gap-based measurement capability information of the UE, so that the network side delivers, according to the received small gap-based measurement capability information, or a combination of the small gap-based measurement capability information and the gap-based measurement capability information, measurement configuration information carrying the small gap measurement configuration information to the UE, and the network side delivers, according to reported gap-based policy capability information, or a combination of the small gap-based measurement capability information and the gap-based measurement capability information, measurement configuration information carrying the small gap measurement configuration information to the UE.
Step 102: The UE measures a carrier according to the received measurement configuration message.
Specifically, the UE measures multiple carriers according to the received measurement configuration message that carries values of configuration parameters in the gap measurement configuration information or the small gap measurement configuration information.
Specifically, before Step 101, the sending, by the UE, a measurement capability message to the network side includes:
reporting, by the UE by using Radio Resource Control (Radio Resource Control, RRC) signaling, the measurement capability information in the UE that includes the small gap-based measurement capability information and/or the gap-based measurement capability information to the network side.
When the UE has both a small gap measurement capability and a gap measurement capability, the UE may separately report the small gap-based measurement capability information and the gap-based measurement capability information to the network side. When configuration parameters in the small gap-based measurement capability information and the gap-based measurement capability information are the same, and values of the configuration parameters are the same, a piece of general measurement capability information may be jointly used. In this way, signaling consumption can be reduced, and working efficiency of the UE can be improved.

Gap measurement indication information or small gap measurement indication information of any operating band combination manner is used to indicate whether a gap or a small gap is needed, when the UE works in any operating band combination manner, for measuring any carrier or any measurement carrier aggregation manner.
Usually, there are the following carrier aggregation manners: an in-band adjacent carrier aggregation manner, an in-band non-adjacent carrier aggregation manner, and a cross-band non-adjacent carrier aggregation manner. Specifically, the carrier aggregation manner may be indicated by using a frequency band combination. For each frequency band in the frequency band combination, a frequency band level is defined. For example, in a definition, in a frequency band A, B, or C, the UE supports a configuration of a carrier having a bandwidth less than 100 physical resource blocks (PRB), and a corresponding frequency band level is X. In a frequency band D, a configuration of two carriers having a total bandwidth less than 200 PRBs is supported, and a corresponding frequency band level is Y. That is, in the frequency band D, the UE may use two carriers for aggregation. A carrier aggregation manner A+D indicates that the UE may perform carrier aggregation by using three carriers in total: one carrier in the frequency band A and two carriers in the frequency D. Certainly, the carrier aggregation manner may further be indicated by directly using a specific carrier. For example, F1 indicates a carrier 1, F2 indicates a carrier 2, and F1+F2 indicates carrier aggregation of the carrier 1 and the carrier 2.
In an example 1, when the small gap-based measurement capability information includes at least one working carrier aggregation manner and small gap measurement indication information of at least one frequency band that corresponds to each working carrier aggregation manner, as shown in Table 1, A, B, C, D separately indicate four frequency bands, and “Yes/No” indicates that a value of the small gap measurement indication information is “Yes” or “No”. When the value is Yes, it indicates that small gap measurement is needed. When the value is No, it indicates that small gap measurement is not needed.
In an example 2, when the small gap-based measurement capability information includes at least one working carrier aggregation manner and small gap measurement indication information of at least one frequency band combination that corresponds to each working carrier aggregation manner, as shown in Table 2, A, B, C, D separately indicate four frequency bands, A+B and C+D indicate frequency band combinations, and “Yes/No” indicates that a value of the small gap measurement indication information is “Yes” or “No”. When the value is Yes, it indicates that small gap measurement is needed. When the value is No, it indicates that small gap measurement is not needed.
In an example 3, when the small gap-based measurement capability information includes at least one working carrier aggregation manner and small gap measurement indication information of each working carrier aggregation manner, as shown in Table 3, “Yes/No” indicates the same as described above.
In an example 4, when the small gap-based measurement capability information includes at least one working carrier aggregation manner and small gap measurement indication information of at least one measurement carrier aggregation manner that corresponds to each working carrier aggregation manner, as shown in Table 4, “Yes/No” indicates the same as described above.
In an example 5, when the small gap-based measurement capability information includes at least one operating band combination manner and small gap measurement indication information of at least one frequency band combination that corresponds to each operating band combination manner, as shown in Table 5, “Yes/No” indicates the same as described above.

Spectrum management is a spectrum planning method established for effectively using a radio frequency. In current spectrum management, a spectrum is classified as a licensed spectrum (licensed spectrum) or an unlicensed spectrum (unlicensed spectrum). A licensed spectrum refers to a spectrum resource, where a particular mobile operator or a particular mobile technology (a Universal Mobile Telecommunications System (Universal Mobile Telecommunications System, UMTS)/Long Term Evolution (Long Term Evolution, LTE) system) is fixedly licensed to use the spectrum resource. An unlicensed spectrum refers to a spectrum resource that can be used and shared by different wireless devices. Devices in a wireless local area network (Wireless Fidelity, WiFi) mostly work in the unlicensed spectrum. In China, the unlicensed spectrum includes 2.4-2.4835 GHz and 5.725-5.850 GHz, or the like.
With rapid development of communications technologies, users have growing demands on mobile bandwidths. Mobile operators need more spectrum resources to satisfy the demands of the users, so as to make up a present situation in which current licensed spectrums cannot fully satisfy communications service demands of the users. Because currently utilization of frequency bands of unlicensed spectrums is relatively low, increasing mobile operators hope to provide communications services to the users by using the unlicensed spectrums. For example, an operator hopes to deploy a 3rd Generation Partnership Project (3GPP) network (for example, LTE) in an unlicensed spectrum, so that the operator can perform cooperative communication with an existing LTE network of the operator.
In an LTE system, in order to improve spectrum utilization, so that service quality assurance can be provided for user equipment within a network, and prevent UE from encountering a radio link connection failure (RLF), the UE often needs to measure radio link monitoring (RLM).
Currently, in carrier aggregation in LTE, the UE performs RLM link monitoring only on a primary cell (PCell). The UE does not need to perform radio link monitoring on a secondary cell (SCell). A network only needs to identify, by monitoring channel state information (CSI) or a channel quality indication (CQI) reported by the UE, whether the UE can schedule data in the SCell, or whether a radio link in the SCell loses a connection. Usually, if the UE reports multiple out-of-range identifiers, the network may consider that the UE cannot schedule data in the SCell or the UE loses a connection.
Currently, measurement for CSI or a CQI is to measure a signal based on a channel state information-reference signal (CSI-RS) resource, or measure a signal on a cell-specific reference signal (CRS) resource, or measure interference on channel state information-interference measurement (CSI-IM) resource.
However, in an unlicensed spectrum, a base station needs to contend for a radio resource. Therefore, to send a CSI-RS or a CRS, the base station needs to obtain a radio resource through contention. If the base station cannot obtain any resource through contention, the base station cannot send a CSI-RS or a CRS. In this case, if the UE further needs to report CSI or a CQI, because the UE does not have a corresponding CSI or CQI measurement resource, the UE probably needs to report an out of range identifier. However, the base station cannot determine, according to received reported Out Of Range, a reason for reporting the identifier. That is, the base station cannot determine whether Out Of Range is reported by the UE due to lack of a measurement resource when the UE still has a connection to the SCell, or whether out of range is reported by the UE when no signal can be obtained through measurement because the UE has lost a connection to the SCell.
Therefore, the embodiments of the present disclosure further provide an SCell channel measurement method and apparatus, so as to resolve problems in the prior art that UE cannot report a status of a link between the UE and an SCell to a network side because the UE cannot monitor the SCell, and that the network side cannot properly schedule the UE because the network side cannot determine the status of the link between the UE and the SCell.
Referring to
Step 701: Receive a CSI measurement indication or a CSI reporting indication sent by a network side, and measure, according to the CSI measurement indication or the CSI reporting indication, a channel corresponding to a secondary serving cell SCell.
Specifically, the receiving a CSI measurement indication or a CSI reporting indication sent by a network side includes:
receiving a periodic CSI measurement indication or a periodic CSI reporting indication that is sent by the network side by using Radio Resource Control (Radio Resource Control, RRC) signaling; or receiving an aperiodic CSI measurement indication or an aperiodic CSI reporting indication that is sent by the network side by using physical layer signaling.
Specifically, the measuring, according to the CSI measurement indication or the CSI reporting indication, a channel corresponding to an SCell includes:
determining a location of a CSI measurement reference resource according to a location of a reporting subframe carried in the CSI measurement indication or the CSI reporting indication, and measuring the CSI measurement reference resource corresponding to the location of the CSI measurement reference resource.
The CSI measurement reference resource includes at least one or a combination of the following: a CRS, a CSI-RS, or CSI-IM.
Step 702: Determine CSI report information according to a channel measurement result, and report the CSI report information to the network side.
Specifically, step 702 is performed in the following manners:
in a first manner, determining whether there is a CSI measurement reference resource, and determining the CSI reporting information according to a determining result and the channel measurement result; or
in a second manner, determining a current channel state of the SCell, and determining the CSI reporting information according to the current channel state and the channel measurement result; or
in a third manner, determining whether there is a CSI measurement reference resource, determining a current channel state of the SCell, and determining the CSI reporting information according to a determining result, the current channel state, and the channel measurement result.
Specifically, whether there is a CSI measurement reference resource is determined in the following manners:
receiving a reference resource indication sent by the network side, where the reference resource indication includes a time period for sending a reference signal, or a time period for canceling sending of a reference signal, or a time period for stop sending a reference signal; and determining, according to the reference resource indication, whether there is a reference signal, and determining, according to a determining result of a reference signal, whether there is a CSI measurement reference resource to which a reference signal belongs; or
measuring a reference signal at the location of the CSI measurement reference resource, and obtaining a measurement value of the reference signal; comparing the measurement value of the reference signal with a specified first threshold; and if the measurement value of the reference signal is greater than or equal to the first threshold, determining that there is a CSI measurement reference resource; otherwise, determining that there is no CSI measurement reference resource.
The first threshold is preset or is configured based on a base station.
The current channel state of the SCell is determined in the following manners:
performing RLM on the SCell, and if an RLM result is a radio link failure RLF, determining that the current channel state is an abnormal state; otherwise, determining that the current channel state is a normal state; or
measuring, within a specified time period, a reference signal parameter corresponding to the SCell, and if the reference signal parameter is less than a specified second threshold, and/or if a quantity of times that the measured reference signal parameter corresponding to the SCell is less than the specified second threshold is greater than or equal to a specified quantity of times, determining that the current channel state is an abnormal state; otherwise, determining that the current channel state is a normal state; or
if the UE configures a channel of another SCell other than the channel of the SCell, to perform data scheduling, or if the UE moves out of a coverage range of the SCell, or if the UE is asynchronous with the SCell, or if it is measured that a CQI of the SCell is less than a specified third threshold, determining that the current channel state is an abnormal state; otherwise, determining that the current channel state is a normal state.
That the current channel state is a normal state indicates that the UE can normally track a reference signal of the SCell, and the normal state includes a synchronization state and a video tracking success state. That the current channel state is an abnormal state indicates that the UE cannot normally track a reference signal of the SCell, and the abnormal state includes an out-of-synchronization state and a time-frequency tracking failure state.
When step 702 is performed in the first manner, specifically, the determining the CSI reporting information according to a determining result and the channel measurement result includes:
when the determining result is that there is a CSI measurement reference resource, using a measurement result of the CSI measurement reference resource as the CSI reporting information; or
when the determining result is that there is no CSI measurement reference resource, using a prestored effective CSI measurement result or a preset CSI measurement value as the CSI reporting information, where the effective CSI measurement result is a non Out Of Range CSI measurement result.
When step 702 is performed in the second manner, specifically,
the determining the CSI reporting information according to the current channel state and the channel measurement result includes:
when the current channel state is a normal state, using a measurement result of the CSI measurement reference resource as the CSI reporting information; or
when the current channel state is an abnormal state, setting the CSI reporting information to Out Of Range or a reference signal tracking failure indication of the SCell.
When step 702 is performed in the third manner, specifically, the determining the CSI reporting information according to a determining result, the current channel state, and the channel measurement result includes:
when the current channel state is a normal state, and the determining result is that there is a CSI measurement reference resource, using a measurement result of the CSI measurement reference resource as the CSI reporting information; or
when the current channel state is a normal state, and the determining result is that there is no CSI measurement reference resource, using a prestored effective CSI measurement result or a preset CSI measurement value as the CSI reporting information, where the effective CSI measurement result is a non-out-of-range CSI measurement result, where the prestored effective CSI measurement result is usually historical information; or
when the current channel state is an abnormal state, setting the CSI reporting information to out of range or a reference signal tracking failure indication of the SCell.
Usually, the CSI reporting information includes a CSI level identifier. The CSI level identifier is determined according to a CSI measurement result. A higher level indicates a better channel state represented by the CSI measurement result.
By means of the SCell channel measurement method provided in this embodiment of the present disclosure, UE receives a CSI measurement indication or a CSI reporting indication sent by a network side, measures, according to the CSI measurement indication or the CSI reporting indication, a channel corresponding to an SCell, determines CSI reporting information according to a channel measurement result, and reports the CSI reporting information to the network side, so that a channel of the SCell is measured, and the channel of the SCell is reported to the network side, thereby resolving a problem in the prior art that UE cannot report a status of a link between the UE and an SCell to a network side because the UE cannot monitor the SCell.
With reference to the foregoing embodiments, referring to
Step 801: Send a CSI measurement indication or a CSI reporting indication to UE, so that the UE measures, according to the CSI measurement indication or the CSI reporting indication, a channel corresponding to an SCell.
Specifically, the sending a CSI measurement indication or a CSI reporting indication to UE includes:
sending, by the network side, a periodic CSI measurement indication or a periodic CSI reporting indication to the UE by using RRC signaling; or
sending, by the network side, an aperiodic CSI measurement indication or an aperiodic CSI reporting indication to the UE by using physical layer signaling.
Step 802: Receive CSI reporting information that is reported by the UE and that is determined according to a channel measurement result.
Step 803: Determine, according to the CSI reporting information, scheduling of the UE.
Specifically, performing step 503 includes:
determining, according to a location of a reporting subframe receiving the CSI reporting information, whether there is a CSI measurement reference resource; and
determining, according to a determining result and the CSI reporting information, scheduling of the UE.
Specifically, the determining, according to a determining result and the CSI reporting information, scheduling of the UE specifically includes:
when the determining result is that there is a CSI measurement reference resource, and the CSI reporting information does not include out of range and does not include a reference signal tracking failure indication of the SCell, performing data transmission scheduling on the UE according to the CSI reporting information;
when the determining result is that there is a CSI measurement reference resource, and the CSI reporting information includes out of range or includes a reference signal tracking failure indication of the SCell, skipping performing data transmission scheduling on the UE;
when the determining result is that there is no CSI measurement reference resource, and the CSI reporting information includes out of range or includes a reference signal tracking failure indication of the SCell, skipping performing data transmission scheduling on the UE; or
when the determining result is that there is no CSI measurement reference resource, and the CSI reporting information does not include out of range and does not include a reference signal tracking failure indication of the SCell, performing data transmission scheduling on the UE according to the CSI reporting information.
Specifically, when the determining result is that there is a CSI measurement reference resource, and the CSI reporting information does not include out of range and does not include a reference signal tracking failure indication of the SCell, the network side may determine that an SCell channel state of the UE is a normal state, and perform data transmission scheduling on the UE according to the CSI reporting information. For example, if a CSI level identifier included in the reported CSI reporting information is relatively high, a relatively large data block is scheduled to the UE for data transmission.
When the determining result is that there is a CSI measurement reference resource, and the CSI reporting information includes out of range or includes a reference signal tracking failure indication of the SCell, the network side may determine that an SCell channel state of the UE is an abnormal state, or an instantaneous channel of the UE becomes worse, and the network side does not schedule the UE to send or receive data.
When the determining result is that there is no CSI measurement reference resource, and the CSI reporting information includes out of range or includes a reference signal tracking failure indication of the SCell, the network side may determine that an SCell channel state of the UE is an abnormal state, and the network side does not schedule the UE to send or receive data, or deactivates the SCell of the UE.
When the determining result is that there is no CSI measurement reference resource, and the CSI reporting information does not include out of range and does not include a reference signal tracking failure indication of the SCell, the network side may determine that an SCell channel state of the UE is a normal state. In addition, it can be learned according to the third manner in step 702 that the CSI reporting information may be historical information. Therefore, data transmission scheduling may be performed on the UE with reference to the historical information in the CSI reporting information.
By means of the SCell channel measurement method provided in this embodiment of the present disclosure, a network side sends a CSI measurement indication or a CSI reporting indication to UE, so that the UE measures a channel and reports a measurement result to the network side in a form of CSI reporting information. The network determines, based on the CSI reporting information, scheduling of the UE, and the network side may obtain an SCell channel state that is reported by the UE by monitoring a channel of an SCell, so that data transmission scheduling can be performed on the UE, thereby resolving problems in the prior art that UE cannot report a status of a link between the UE and an SCell to a network side because the UE cannot monitor the SCell, and that the network side cannot properly schedule the UE because the network side cannot determine the status of the link between the UE and the SCell.
