Embodiments of the present invention relate to the field of wireless communications, and in particular, to a carrier aggregation capability reporting apparatus and method, and a carrier measurement apparatus and method.
A Long Term Evolution (LTE for short) system needs to provide transmission bandwidth of a maximum of 100 MHZ, so that a downlink transmission peak speed can reach 1 Gbps, and an uplink transmission peak speed can reach 500 Mbps. To resolve a scarcity of a contiguous spectrum of high bandwidth, a carrier aggregation (CA for short) scheme is proposed in the LTE system. Carrier aggregation means that two or more component carriers (CC for short) are aggregated to support higher transmission bandwidth. Maximum transmission bandwidth may reach 100 MHz.
At present, in the carrier aggregation scheme, a user equipment (UE for short) needs to report a carrier aggregation capability to a base station. The carrier aggregation capability includes capability information of a carrier combination supported by the UE, and the capability information may specifically include information such as a quantity and bandwidth of aggregation carriers in the carrier combination supported by the UE, whether the aggregation carriers are contiguous carriers, and a multiple-input multiple-output (MIMO for short) capability corresponding to each carrier.
In an existing reporting mechanism, the UE needs to report information about each carrier combination supported by the UE to the base station, and indicate capability information corresponding to the carrier combination. If the UE supports a high-level aggregation capability, it cannot implicitly indicate that the UE supports a low-level aggregation capability. Therefore, even if the UE separately reports information about two carrier combinations supported by the UE to the base station, and one carrier combination (corresponding to a low-level aggregation capability) is a sub-combination of the other carrier combination (corresponding to a high-level aggregation capability), the UE still needs to perform reporting for each carrier combination. If the two carrier combinations are corresponding to same capability information, the UE performs repeated reporting, and signaling resources used for reporting are wasted. For example, the UE supports BAND_A (two contiguous carriers)+BAND_B (one carrier), but it cannot implicitly indicate that the UE supports BAND_A (one contiguous carrier)+BAND_B (one carrier). BAND_A (one contiguous carrier)+BAND_B (one carrier) is a sub-combination of BAND_A (two contiguous carriers)+BAND_B (one carrier) supported by the UE. If the UE supports BAND_A (one contiguous carrier)+BAND_B (one carrier), the UE needs to separately report, to the base station, information indicating that the UE supports BAND_A (one contiguous carrier)+BAND_B (one carrier).
In the existing reporting mechanism, when the UE reports the capability information of the carrier combination supported by the UE to the base station, the UE can report only the lowest capability in capabilities corresponding to carriers in the carrier combination because the carriers in the carrier combination are corresponding to different capabilities, for example, different MIMO capabilities, or different channel state information (CSI for short) capabilities. The MIMO capability is used as an example. If the carrier combination supported by the UE includes two carriers, one carrier supports four-layer MIMO, and the other carrier supports eight-layer MIMO, the UE can report only a four-layer MIMO capability. In this reporting mechanism, the base station cannot thoroughly learn capabilities of carriers supported by the UE.
In another prior art, the UE may report, in a first set (supported Band Combination) and a second set (supported Band Combination Add), a capability of a carrier combination supported by the UE. The capability of the carrier combination includes a single-carrier capability and a multi-carrier capability. Each element in the first set or the second set indicates, according to a first format, a carrier combination supported by the UE and a capability corresponding to the carrier combination, such as a MIMO capability or a CSI capability. For example, an element is a combination of a frequency band 1 and a frequency band 2, and in the combination, the frequency band 1 supports aggregation of two carriers, and the frequency band 2 supports aggregation of two carriers. Only one MIMO capability corresponding to the element is that four carriers each support 2×2 MIMO, and a CSI capability corresponding to the element is that CSI of each carrier supports two processes. When the UE receives a capability reporting request from the base station, if the request does not carry a reporting indication for a specific frequency band, the UE fills a carrier aggregation capability of the UE in the first set, and reports the carrier aggregation capability. If the first set cannot accommodate all UE capabilities, the UE does not report a UE capability that cannot be accommodated by the first set. If the request carries a reporting indication for a specified frequency band, the UE first fills, in the first set, a carrier aggregation capability of the UE within a range of the specified frequency band. If the first set cannot accommodate all UE capabilities within the range of the specified frequency band, the UE fills a remaining capability in the second set, and reports the remaining capability. If the second set cannot accommodate all the remaining UE capabilities, the UE does not report a UE capability that cannot be accommodated by the second set. At present, a UE capability is stored in a serving base station and an MME (mobility management entity) of the UE after being reported. After the UE moves, the serving base station or the MME transfers the UE capability to a new serving base station. In this reporting manner, a format of an element in a set cannot be changed. If the format is changed, the UE capability cannot be reported by using the first set and the second set, and consequently, evolution of the UE capability is limited.
When working in a carrier aggregation scenario, the UE measures a frequency of an aggregation carrier according to a measurement control message delivered by a network side. Measurement may be classified into intra-frequency frequency measurement and inter-frequency frequency measurement according to different carriers on which measured frequencies are located. When a carrier on which a frequency measured by the UE is located is different from a carrier on which a serving cell is located, measurement performed by the UE is referred to as the inter-frequency frequency measurement. The UE performs the inter-frequency frequency measurement in a measurement gap configured by the base station. In the measurement gap, the base station does not schedule the UE, and the UE temporarily interrupts communication with the serving cell, and performs the inter-frequency frequency measurement. However, at present, when performing the inter-frequency frequency measurement, the UE is allowed to parallelly measure a maximum of three inter-frequencies. A quantity of frequencies measured by the UE is limited, and consequently, work efficiency of the UE is reduced.
Embodiments of the present invention provide a carrier aggregation capability reporting apparatus and method, so as to prevent UE from repeatedly reporting capability information corresponding to a carrier combination supported by the UE, and reduce waste of signaling resources used for reporting.

The UE parallelly measures the inter-frequencies of the carrier in the carrier aggregation in the measurement gap according to the measurement configuration information.

According to a technical method in this embodiment, a quantity of inter-frequencies that are in the carrier aggregation supported by the UE and that are parallelly measured by the UE can be increased.
The following clearly describes the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are merely some but not all of the embodiments of the present invention. All other embodiments obtained by persons of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.
The technical solutions in the present invention may be applied to various communications systems such as a Global System for Mobile Communications (GSM for short), a Code Division Multiple Access (CDMA for short) system, a Wideband Code Division Multiple Access (WCDMA for short) system, a general packet radio service (GPRS for short) system, a Long Term Evolution (LTE for short) system, and a Universal Mobile Telecommunications System (UMTS for short). This is not limited in the present invention.
In the embodiments of the present invention, user equipment (UE for short) may also be referred to as a mobile terminal, mobile user equipment, and the like, and may communicate with one or more core network devices via a radio access network (RAN for short). The UE may be a mobile terminal, such as a mobile phone (also referred to as a “cellular” phone) and a computer with a mobile terminal. For example, the UE may be a portable, pocket-sized, handheld, computer built-in, or in-vehicle mobile apparatus that exchanges a voice and/or data with the radio access network. This is not limited in the present invention.
A base station has a function of receiving and sending data. A corresponding sending device and receiving device may be UE, a base station controller, a core network device, and a master eNodeB. This is not limited in the present invention. The base station may be a base transceiver station (BTS for short) in a GSM or CDMA, or may be a NodeB (NodeB) in WCDMA, or may be an evolved NodeB (eNB for short) in LTE. This is not limited in the present invention. The base station includes control nodes of various access network nodes, for example, a radio network controller (RNC for short) in a UMTS, or a controller that manages multiple small cells.
In the embodiments of the present invention, an LTE communications system is used as an example, but this is not limited herein. As shown in
The technical solutions in the present invention relate a carrier aggregation technology. Carrier aggregation means that two or more component carriers (CC for short) are aggregated to support higher transmission bandwidth. Maximum transmission bandwidth of each component carrier is 20 MHz, and the maximum transmission bandwidth may reach 100 MHz by using the carrier aggregation technology. As shown in
As shown in
S301. User equipment UE determines information about a carrier combination supported by the UE and information about a sub-combination that is of the carrier combination and that is supported by the UE.
S302. The UE reports, to a base station, the determined information about the carrier combination supported by the UE and the determined information about the sub-combination that is of the carrier combination and that is supported by the UE.
In this embodiment, the information that is determined by the UE and that is about the carrier combination supported by the UE may include information such as a carrier aggregation band class on each frequency band of the carrier combination, a MIMO capability corresponding to the carrier aggregation band class on each frequency band, and a CSI capability corresponding to the carrier aggregation band class on each frequency band. The carrier aggregation band class includes a downlink carrier aggregation band class and an uplink carrier aggregation band class. The carrier aggregation band class further includes a carrier quantity and total carrier bandwidth.
For example, the UE supports a carrier combination BAND_A (DL Class B, UL Class A)+BAND_B (DL Class B). BAND_A (DL Class B, UL Class A)+BAND_B (DL Class B) indicates aggregation of a frequency band A and a frequency band B. The frequency band A includes downlink carrier aggregation of a band class B and uplink carrier aggregation of a band class A. The frequency band B includes downlink carrier aggregation of a band class B. Total bandwidth and carrier quantities corresponding to different carrier aggregation band classes are shown in Table 1.
In this embodiment, the sub-combination of the carrier combination is a carrier combination that includes different carrier aggregation band classes on each frequency band of the carrier combination. A carrier combination BAND_A (DL Class B, UL Class A)+BAND_B (DL Class B, UL Class A) is used as an example. A sub-combination of the carrier combination BAND_A (DL Class B, UL Class A)+BAND_B (DL Class B, UL Class A) is shown in Table 2. BAND_A (DL Class B, UL Class A)+BAND_B (DL Class B, UL Class A) is an original carrier combination in Table 2.
In this embodiment, if the UE supports a sub-combination of the carrier combination, and capability information corresponding to the sub-combination that is of the carrier combination and that is supported by the UE is the same as capability information corresponding to the carrier combination supported by the UE, the UE may directly report information about the sub-combination that is of the carrier combination and that is supported by the UE to the base station. If the UE supports a sub-combination of the carrier combination, but capability information corresponding to the sub-combination that is of the carrier combination and that is supported by the UE is different from capability information corresponding to the carrier combination supported by the UE, the UE may separately report information about the sub-combination that is of the carrier combination and that is supported by the UE to the base station, and report the capability information corresponding to the sub-combination that is of the carrier combination and that is supported by the UE to the base station.
Optionally, the UE may report the information about the sub-combination that is of the carrier combination and that is supported by the UE to the base station by using the following two implementations.
In a first implementation, the UE and the base station predefine a sequence number (for example, Table 2) corresponding to each sub-combination of the carrier combination, and the UE and the base station predefine that when a bit of a sequence number corresponding to a sub-combination is set to a first value, it indicates that the UE supports the sub-combination, and capability information corresponding to the sub-combination is the same as the capability information corresponding to the original carrier combination of the sub-combination; and when a bit of a sequence number corresponding to a sub-combination is set to a second value, it indicates that the UE does not support the sub-combination.
For any sub-combination of the carrier combination supported by the UE, when the UE determines that the UE supports the sub-combination, and capability information corresponding to the sub-combination is the same as the capability information corresponding to the original carrier combination of the sub-combination, a bit of a sequence number corresponding to the sub-combination is set to the first value; and when the UE determines that the UE does not support the sub-combination, a bit of a sequence number corresponding to the sub-combination is set to the second value. Then the UE reports specified bits to the base station according to a sequence of sequence numbers corresponding to the bits. If the UE supports a sub-combination of the carrier combination, but capability information corresponding to the sub-combination that is of the carrier combination and that is supported by the UE is different from the capability information corresponding to the carrier combination supported by the UE, the UE may separately report information about the sub-combination that is of the carrier combination and that is supported by the UE to the base station, and report the capability information corresponding to the sub-combination that is of the carrier combination and that is supported by the UE to the base station.
With reference to Table 2, for example, the first value is 1 and the second value is 0. When the specified bits reported by the UE to the base station are 111100011, the base station may learn from Table 2 predefined by the base station and the UE that the UE supports sub-combinations separately corresponding to sequence numbers 1, 2, 3, 4, 8, and 9 in Table 2, capability information separately corresponding to the sub-combinations is the same as capability information corresponding to the original carrier combination BAND_A (DL Class B, UL Class A)+BAND_B (DL Class B, UL Class A), and the UE does not support sub-combinations separately corresponding to sequence numbers 5, 6, and 7 in Table 2. In this way, the UE can report the information about the sub-combination that is of the carrier combination and that is supported by the UE to the base station. Therefore, a prior-art problem that the UE repeatedly reports a carrier combination supported by the UE and a sub-combination of the carrier combination is avoided, and reporting signaling overheads are reduced.
In a second implementation, the UE and the base station predefine a sequence number (for example, Table 2) corresponding to each sub-combination of the carrier combination. The UE reports a sequence number corresponding to a sub-combination that is of the carrier combination and that is supported by the UE to the base station. For example, after determining that the UE supports sub-combinations separately corresponding to sequence numbers 1, 2, 3, 4, 8, and 9 in Table 2, the UE reports 123489 to the base station. After receiving this message, the base station may learn from Table 2 predefined by the base station and the UE that the UE supports the sub-combinations separately corresponding to the sequence numbers 1, 2, 3, 4, 8, and 9 in Table 2.
It should be noted that, in this embodiment, the sequence number that is predefined by the UE and the base station and that is corresponding to a sub-combination of the carrier combination is not limited to a form in Table 2, and may be in another form. The first value and the second value predefined by the UE and the base station are not limited to values provided in this embodiment, and may be other values.
In this embodiment, optionally, after the UE reports the determined information about the carrier combination supported by the UE to the base station, the UE and the base station may consider by default that the UE supports all sub-combinations of the carrier combination, and capability information corresponding to each of the all sub-combinations is the same as the capability information corresponding to the carrier combination. When the UE determines that capability information corresponding to a sub-combination supported by the UE is different from the capability information corresponding to the carrier combination, the UE may separately report information about the sub-combination supported by the UE to the base station, and report the capability information corresponding to the sub-combination to the base station. Optionally, the UE may receive indication information sent by the base station, and the indication information is used to indicate that the UE and the base station consider by default that the UE supports all sub-combinations of the carrier combination supported by the UE. After the UE reports the information about the carrier combination supported by the UE to the base station, the UE and the base station may consider, by default based on the received indication information, that the UE supports all the sub-combinations of the carrier combination supported by the UE.
It should be noted that a manner of reporting, by the UE, the information about the sub-combination that is of the carrier combination and that is supported by the UE to the base station is not limited to the manner provided in this embodiment, and may be in another form.
As shown in

Optionally, the apparatus further includes:
When reporting the information, determined by the processor 501, about the sub-combination that is of the carrier combination and that is supported by the UE to the base station, the transceiver 502 is specifically configured to:
In this embodiment, the UE reports, to the base station, the information about the carrier combination supported by the UE and the information about the sub-combination that is of the carrier combination and that is supported by the UE. The capability information corresponding to the carrier combination supported by the UE is the same as the capability information corresponding to the sub-combination that is of the carrier combination and that is supported by the UE, and the UE may directly report the information about the sub-combination that is of the carrier combination and that is supported by the UE to the base station, and does not need to follow an existing reporting mechanism in which the UE needs to perform reporting for each carrier combination supported by the UE, and indicate capability information corresponding to each carrier combination. Therefore, according to a technical solution provided in this embodiment, a problem in the existing reporting mechanism that the UE repeatedly reports capability information corresponding to a carrier combination can be avoided, and waste of signaling resources used for reporting can be reduced.
As shown in
S601. User equipment UE determines capability information corresponding to each carrier in a carrier combination supported by the UE, where the capability information includes a multiple-input multiple-output MIMO capability and/or a CSI capability.
S602. The UE reports, to a base station, the determined capability information corresponding to each carrier.
In this embodiment, the capability information corresponding to each carrier may include the MIMO capability and/or the CSI capability, but is not limited thereto.
In this embodiment, the UE and the base station predefine a sequence number. Each predefined sequence number indicates a set including capability information corresponding to each carrier in the carrier combination supported by the UE. The UE reports the capability information corresponding to each carrier in the carrier combination supported by the UE to the base station according to the predefined sequence number.
There may be the following two implementations for the sequence number predefined by the UE and the base station.
In a first implementation, the sequence number predefined by the UE and the base station is included in a same list, and the list includes all sets including capability information corresponding to each carrier in the carrier combination. That is, the carrier combination supported by the UE is used as a whole, and a list is configured for the carrier combination. The list includes all sets including capability information corresponding to each carrier in the carrier combination. Each set is corresponding to a sequence number. For example, the UE supports a carrier combination A, the carrier combination A includes a frequency band 1 and a frequency band 2, the frequency band 1 and the frequency band 2 include N carriers in total, and capability information corresponding to each carrier in the carrier combination A forms M sets. In this case, a sequence number list predefined by the UE and the base station for the carrier combination A is shown in Table 3.
In Table 3, capability information corresponding to each carrier includes a MIMO capability and a CSI capability. In this embodiment, the UE and the base station may further predefine a sequence number for a type of capability information. For example, the UE performs predefining for a MIMO capability corresponding to a carrier. A list in which a sequence number predefined by the UE and the base station is located is shown in Table 4.
Likewise, capability information corresponding to the carrier may further include a network-assisted interference cancellation and suppression (NAICS for short) capability. Content and a type quantity of capability information corresponding to a carrier in the predefined list are not limited in this embodiment. In the first implementation, the list predefined by the UE and the base station may include in detail all sets including capability information corresponding to each carrier in the carrier combination, or may include only some pieces of typical configuration information, so as to reduce a length of the table.
In a second implementation, the sequence number predefined by the UE and the base station is included in lists whose quantity is the same as a frequency band quantity of the carrier combination, and each list includes all sets including capability information corresponding to each carrier in a carrier band class of a same frequency band. That is, a carrier band class of each frequency band of the carrier combination supported by the UE is used as a whole. The carrier band class of each frequency band is corresponding to a list. The list includes all sets including capability information corresponding to each carrier of the carrier band class of the frequency band, and each set is corresponding to a sequence number. For example, the UE supports a carrier combination A, capability information includes a MIMO capability and a CSI capability, and the carrier combination A includes a frequency band 1 and a frequency band 2. A carrier band class of the frequency band 1 is B. It may be learned from Table 1 that the frequency band 1 has two carriers, and capability information corresponding to each carrier on the frequency band 1 forms six sets in total. A carrier band class of the frequency band 2 is E. It may be learned from Table 1 that the frequency band 2 has four carriers, and capability information corresponding to each carrier on the frequency band 2 forms eight sets in total. In this case, sequence number lists predefined by the UE and the base station for the frequency band 1 and the frequency band 2 are shown in Table 5 and Table 6, respectively.
Likewise, content and a type quantity of capability information corresponding to a carrier in the predefined list are not limited in this embodiment. In the second implementation, two adjacent frequency bands may have consecutive sequence numbers. For example, the sequence numbers in Table 6 may be successively 6 to 13.
In this embodiment, the UE may report the capability information corresponding to each carrier in the carrier combination supported by the UE to the base station by using the following two implementations according to the sequence number predefined by the UE and the base station.
In a first implementation, the UE and the base station predefine a sequence number corresponding to a set including capability information corresponding to each carrier in the carrier combination, and the UE and the base station predefine that when a bit of a sequence number is set to a first value, it indicates that the UE supports capability information corresponding to each carrier in a set corresponding to the sequence number; and when a bit of a sequence number is set to a second value, it indicates that the UE does not support capability information corresponding to each carrier in a set corresponding to the sequence number.
For any set including capability information corresponding to carriers, when determining that the UE supports capability information corresponding to each carrier in the set, the UE sets a bit of a sequence number corresponding to the set to the first value; and when determining that the UE does not support capability information corresponding to each carrier in the set, the UE sets a bit of a sequence number corresponding to the set to the second value. Then the UE reports specified bits to the base station according to a sequence of sequence numbers corresponding to the bits.
For example, with reference to Table 3, if M is 9, the first value is 1, and the second value is 0, when the specified bits reported by the UE to the base station are 111100011, the base station may learn from Table 3 predefined by the base station and the UE that the UE supports capability information corresponding to each carrier in sets separately corresponding to sequence numbers 1, 2, 3, 4, 8, and 9 in Table 3, but the UE does not support capability information corresponding to each carrier in sets separately corresponding to sequence numbers 5, 6, and 7 in Table 3.
In a second implementation, the UE and the base station predefine a sequence number corresponding to a set including capability information corresponding to each carrier in the carrier combination. The UE reports a sequence number corresponding to a set including corresponding capability information supported by the UE to the base station. For example, with reference to Table 3, it is assumed that M is 9. After determining that the UE supports capability information corresponding to each carrier in sets separately corresponding to sequence numbers 1, 2, 3, 4, 8, and 9 in Table 3, the UE reports 123489 to the base station. After receiving this message, the base station may learn from Table 3 predefined by the base station and the UE that the UE supports the capability information corresponding to each carrier in the sets separately corresponding to the sequence numbers 1, 2, 3, 4, 8, and 9 in Table 3.
It should be noted that a type of a set including capability information corresponding to each carrier and a sequence number corresponding to the set are not limited to content provided in this embodiment, and may be other content, where the type of the set and the sequence number corresponding to the set are predefined by the UE and the base station. The first value and the second value predefined by the UE and the base station are not limited to values provided in this embodiment, and may be other values.
In this embodiment, optionally, before reporting capability information corresponding to a carrier to the base station, the UE may receive carrier range information sent by the base station. The carrier range information is used for instructing the UE to report the capability information corresponding to the carrier to the base station. The carrier range information includes at least one type of the following information:
The aggregation carrier bandwidth range may include a bandwidth range of aggregation of specified frequency bands or a total bandwidth range of aggregation of all frequency bands. For example, the aggregation carrier bandwidth range included in the carrier range information sent by the base station is as follows: A bandwidth range of a frequency band 1 is a carrier class B, or an upper bandwidth limit of the frequency band 1 is 20 M, and when the UE reports capability information corresponding to a carrier on the frequency band 1, the UE needs to report only capability information corresponding to a carrier within the carrier class B on the frequency band 1, or the UE needs to report only capability information corresponding to a carrier that has bandwidth within 20 M on the frequency band 1.
The aggregation carrier type may include a licensed carrier or an unlicensed carrier. For example, the aggregation carrier type included in the carrier range information sent by the base station is the licensed carrier, and when reporting capability information corresponding to a carrier, the UE needs to report only capability information corresponding to the licensed carrier.
The aggregation carrier quantity range may include a carrier quantity range of a specified aggregation frequency band, or a range of a sum of carrier data included in all aggregation frequency bands. For example, an upper limit of the carrier quantity range included in the carrier range information sent by the base station is 10, and the UE needs to report only capability information corresponding to a maximum of 10 carriers. Alternatively, the base station requires the UE to report capability information corresponding to a maximum of 10 carriers on a specified frequency band A, and the UE needs to report only capability information corresponding to a maximum of 10 carriers on the frequency band A. Optionally, when reporting capability information, the UE adds the carrier range information received from the base station to the capability information, so that when the capability information is transferred to another base station, the another base station learns that the capability information is reported for a carrier range. Optionally, before the UE receives the carrier range information sent by the base station, the UE reports information about a maximum carrier aggregation capability supported by the UE to the base station, and the information about the maximum carrier aggregation capability is used by the base station to send the carrier range information to the UE.
In this way, the UE may report capability information corresponding to a carrier to the base station according to the carrier range information sent by the base station. The UE does not need to report capability information corresponding to all carriers supported by the UE to the base station, so that reporting signaling waste is avoided.
In an embodiment, before the UE reports capability information corresponding to a carrier to the base station, the UE receives a capability reporting request sent by the base station, and the capability reporting request includes a first instruction. The UE reports, according to the first instruction by using a third set, determined capability information that is in capability information corresponding to each supported carrier combination and that meets a first condition. The first condition includes a carrier combination whose UE carrier capability is within a preset range and/or a carrier combination whose frequency band is an unlicensed frequency band. The third set is a set different from a first set and a second set.
Specifically, the UE fills, in the first set, determined capability information that is in the capability information corresponding to each supported carrier combination and that does not meet the first condition, and reports the capability information; and fills, in the third set, determined capability information that is in capability information corresponding to each carrier and that meets the first condition, and reports the capability information. Further, if the capability information that does not meet the first condition exceeds a maximum quantity of the first set, remaining capability information that does not meet the first set is filled in the third set and is reported.
The first instruction is an instruction for instructing the UE to report the third set or an instruction for instructing the UE to report a UE capability that meets the first condition.
Specifically, the third set is also used for reporting a carrier aggregation capability supported by the UE. A format of an element in the third set is different from a format of an element in the first set or the second set. The format of the element in the third set is a first format. The format of the element in the third set is more efficient, and can express more capabilities by using a smaller amount of information. For example, in the first set and the second set, each element is corresponding to a carrier combination in a frequency band combination and a MIMO capability or a CSI capability corresponding to the carrier combination. Each element can have only one MIMO/CSI capability combination. Each element in the third set is corresponding to a carrier combination in a frequency band combination, and each element may indicate multiple MIMO/CSI capability combinations. For another example, an element in the third set may indicate that a sub-combination corresponding to the element may also support a capability corresponding to the element. For example, if an element in the third set is a sub-combination that supports three carriers on a frequency band 1 and whose MIMO capability supports 4×4 MIMO and whose CSI capability supports two processes, it may also indicate that the element supports the two carriers on the frequency band 1, a MIMO capability of supporting 4×4 MIMO, and a CSI capability of supporting two processes. Therefore, an element in the third set can indicate a more complex capability, and more UE capability information may be reported by using a smaller quantity of elements. The carrier combination within the preset range includes a UE capability with a quantity of uplink carriers and/or downlink carriers that is greater than a specific quantity, for example, a carrier aggregation capability with a quantity of downlink carriers that is greater than 5.
Further, that the UE determines to report, according to the first instruction by using a third set, UE capability information that meets a first condition includes: The UE first fills the carrier aggregation capability of the UE in the first set, and then fills a remaining capability in the third set according to a format of the third set, and reports the remaining capability. Only a UE capability that does not meet the first condition is filled in the first set, or a UE capability that does not meet the first condition is preferentially filled in the first set.
Specifically, the UE first fills the carrier aggregation capability of the UE in the first set, fills the remaining capability in the third set according to the format of the third set, and reports the remaining capability. Only the UE capability that does not meet the first condition is filled in the first set, or the UE capability that does not meet the first condition is preferentially filled in the first set. If only the UE capability that does not meet the first condition is filled in the first set, even if the first set has remaining space, a UE capability that meets the first condition cannot be filled in the first set, and the UE capability that meets the first condition can be filled only in the third set. In this way, when a capability is transferred between base stations, a legacy base station uses only an element in the set 1, and a new base station uses an element in the set 1 and an element in the set 3.
For example, the first set has a maximum of three elements, and the third set has a maximum of 10 elements. UE capability information is shown in Table 8.
The third element belongs to an unlicensed frequency band, and cannot be filled in the first set. Therefore, the first, second, and fourth elements are filled in the first set. The third, fifth, sixth, seventh, and eighth elements are filled in the third set. The seventh and eighth elements are corresponding to same frequency bands and same carrier combination capabilities, and only MIMO/CSI capabilities are different. Therefore, the seventh and eighth elements can be combined into one element in the third set for reporting. In aggregation of two carriers on the frequency band 3, two MIMO/CSI capability combinations may be supported.
In another embodiment, the capability reporting request further carries an indication of a frequency band range that needs to be reported. That the UE reports, according to the first instruction by using a third set, determined capability information that is in capability information corresponding to each supported carrier combination and that meets a first condition includes: The UE first fills, in the first set, capability information that is in the capability information corresponding to the frequency band range and that does not meet the first condition, and reports the capability information; if the first set cannot accommodate the capability information, the UE fills a remaining capability in the second set, and reports the remaining capability; and if the second set cannot accommodate the remaining capability, the UE fills the remaining capability in the third set according to a format of the third set, and reports the remaining capability. The UE fills, in the third set, determined capability information that is in capability information corresponding to each carrier and that meets the first condition, and reports the capability information.
Specifically, if the reporting request received by the UE further carries the indication of the frequency band range that needs to be reported, the UE first fills, in the first set, a carrier aggregation capability of the UE within the frequency band range, and fills a remaining capability in the second set. If the second set cannot accommodate the remaining capability, the UE fills the remaining capability in the third set according to the format of the third set and reports the remaining capability. Only a UE capability that does not meet the first condition is filled in the first set, or a UE capability that does not meet the first condition is preferentially filled in the first set. If only the UE capability that does not meet the first condition is filled in the first set, even if the first set has remaining space, a UE capability that meets the first condition cannot be filled in the first set, and the UE capability that meets the first condition can be filled only in the third set. When capability information is transferred between base stations, a legacy base station uses elements only in the set 1 and the set 2, and a new base station uses elements in the set 1, the set 2, and the set 3.
For example, UE capability information is shown in Table 9.
It is assumed that a combination that includes fewer than five carriers within a preset range is filled in the first set and the second set, the base station requests the UE to report frequency bands 1, 2, and 3, and a maximum element quantity of the first set and the second set is three. When filling a capability, the UE first selects a capability that has fewer than five carriers on a licensed frequency band, including 1, 4, and 8, to first fill the first set. Then the UE selects remaining capabilities that have fewer than five carriers on the licensed frequency band, including 11 and 12, to fill the second set. Then the UE fills, in the third set, remaining capabilities that belong to frequency bands 1, 2, and 3, including 2, 3, 4, 5, 6, and 7. 2, 3, 4, 5, 6, and 7 are filled according to a format of the set 3, and may be combined into a smaller quantity of elements.
Further, that the UE determines to report, according to the first instruction by using a third set, a UE capability that meets a first condition includes: The UE fills the carrier aggregation capability of the UE in the third set according to the format of the third set, reports the carrier aggregation capability of the UE, and does not report the first set or the second set, so that the base station generates the first set and/or the second set according to the third set, and reports the third set together with the first set and/or the second set to an MME.
Specifically, the UE does not fill the first set any longer, but directly fills the carrier aggregation capability of the UE in the third set according to the format of the third set, and reports the carrier aggregation capability of the UE to the base station. When a capability reported by the UE is transferred, by using a handover process or the MME, to a legacy base station that is incapable of identifying the third set, the legacy base station needs to re-request a UE capability, and the UE re-reports an element in the set 1 or elements in the set 1 and the set 2. To prevent the legacy base station from re-requesting reporting of the UE capability, the base station that receives the third set may generate a first set according to a format of the first set by using some elements in the third set, and then reports a capability formed by combining the first set and the third set to the MME, or transfers the capability to a target base station in the handover process. In this way, a UE capability stored in the MME or the target base station includes the first set and the third set. Even if a capability is subsequently transferred to the legacy base station that is incapable of identifying the third set, the legacy base station can parse a UE capability according to the first set in the UE capability, and does not need to request again the UE to report a capability.

In an embodiment, the transceiver 802 is further configured to receive a capability reporting request sent by the base station, and the capability reporting request includes a first instruction.
The processor 801 is further configured to: report, according to the first instruction by using a third set, determined capability information that is in capability information corresponding to each supported carrier combination and that meets a first condition, and the first condition includes a carrier combination whose UE carrier capability is within a preset range and/or a carrier combination whose frequency band is an unlicensed frequency band. The third set is a set different from a first set and a second set.
In an embodiment, the processor 801 is specifically configured to: fill, in a first set, determined capability information that is in capability information corresponding to each supported carrier combination and that does not meet a first condition, and report the capability information; if the capability information that does not meet the first condition exceeds a maximum quantity of the first set, fill, in a third set, remaining capability information that does not meet the first set, and report the remaining capability information; and fill, in the third set, determined capability information that is in capability information corresponding to each carrier and that meets the first condition, and report the capability information.

In this embodiment, the user equipment UE reports the determined capability information corresponding to each carrier in the carrier combination to the base station, so that the base station can thoroughly learn the capability information corresponding to each carrier in the carrier combination supported by the UE. By means of predefining performed by the UE and the base station, content of capability information that is corresponding to a carrier and that is reported by the UE to the base station is simplified, so that reporting signaling overheads are reduced. The UE reports, according to the carrier range information sent by the base station, the capability information corresponding to the carrier to the base station, and the UE does not need to report capability information corresponding to all carriers supported by the UE to the base station, so that reporting signaling waste is avoided.
As shown in
S901. The user equipment UE reports, to a base station, indication information used to indicate that the UE supports parallel measurement performed in a measurement gap on inter-frequencies of a carrier in carrier aggregation supported by the UE.
S902. The UE receives measurement configuration information of the inter-frequencies of the carrier in the carrier aggregation supported by the UE and that is sent by the base station according to the indication information.
S903. The UE parallelly measures, in the measurement gap according to the received measurement configuration information, the inter-frequencies of the carrier in the carrier aggregation supported by the UE.
Before the UE performs a measurement task, the base station sends a measurement control message to the UE. The measurement control message includes information such as a measurement identifier, a measurement object, and report configuration. The measurement identifier is used to identify measurement control information. The measurement object may include a center frequency of a carrier (that is, an absolute radio frequency channel number (Absolute Radio Frequency Channel Number, ARFCN)), a neighboring cell list of the carrier, and the like. The report configuration may include an event trigger reporting condition, an event trigger reporting period, and the like. The measurement object and the report configuration are used by the UE to perform the measurement task. The UE generates a measurement report according to a measurement result of the measurement task, and sends the measurement report to the base station.
The measurement task of the UE is classified into intra-frequency measurement and inter-frequency measurement according to different carriers on which measurement objects of the UE are located. A measurement task in which a carrier of a measurement object is the same as a carrier on which a serving cell of the UE is located is referred to as the intra-frequency measurement. A measurement task in which a carrier of a measurement object is different from a carrier on which a serving cell of the UE is located is referred to as the inter-frequency measurement. The carrier on which the serving cell of the UE is located may be considered as a center frequency at which the UE communicates with the serving cell. An inter-frequency measurement task does not include a measurement task in an evolved packet core network (EPC for short), for example, a measurement task in which a measurement object is a Universal Mobile Telecommunications System (UMTS for short).
For the intra-frequency measurement, the UE may directly perform measurement, and the base station does not need to configure a measurement gap (measurement gap) for the UE. For the inter-frequency measurement, the base station needs to configure a measurement gap for the UE. The measurement gap is a time interval. In the time interval, the base station does not schedule the UE, and the UE temporarily interrupts the communication with the serving cell, so that the UE performs an inter-frequency measurement task. The base station determines, according to capability information reported by the UE, whether there is a need to configure the measurement gap for the UE. The base station may configure the measurement gap for the UE by using a radio resource control (RRC for short) reconfiguration message. For example, the capability information of the UE is shown in Table 7. When the UE operates on a frequency band X1, the base station needs to configure a measurement gap for the UE when the UE measures a frequency band Y1. When the UE operates on a frequency band (X2+X3), the base station does not need to configure a measurement gap for the UE when the UE measures a frequency band Y2.
In this embodiment, the UE reports, to the base station, the indication information used to indicate that the UE supports the parallel measurement performed in the measurement gap on the inter-frequencies of the carrier in the carrier aggregation supported by the UE. After the UE reports a carrier aggregation capability to the base station, the base station determines the measurement configuration information of the inter-frequencies of the carrier in the carrier aggregation of the UE according to the indication information and the carrier aggregation capability of the UE, then sends the measurement configuration information to the UE, and configures the measurement gap for the UE. The UE parallelly measures the inter-frequencies of the carrier in the carrier aggregation in the measurement gap according to the measurement configuration information. The measurement configuration information includes information about the inter-frequencies of the carrier in the carrier aggregation supported by the UE.
In this embodiment, optionally, the UE receives an RRC reconfiguration message sent by the base station, and the RRC reconfiguration message carries the measurement configuration information that is sent by the base station according to the indication information and that is of the inter-frequencies of the carrier in the carrier aggregation.
For example, as shown in

S1301. The base station receives indication information reported by user equipment UE for indicating that the UE supports parallel measurement performed in a measurement gap on inter-frequencies of a carrier in carrier aggregation supported by the UE.
S1302. The base station determines, according to the indication information, measurement configuration information of the inter-frequencies of the carrier in the carrier aggregation supported by the UE.
S1303. The base station sends the measurement configuration information to the UE.
In this embodiment, the base station receives the indication information sent by the UE for indicating that the UE supports the parallel measurement performed in the measurement gap on the inter-frequencies of the carrier in the carrier aggregation. After receiving a carrier aggregation capability reported by the UE, the base station determines the measurement configuration information of the inter-frequencies of the carrier in the carrier aggregation of the UE according to the indication information and the carrier aggregation capability supported by the UE, and sends the measurement configuration information to the UE. Further, the UE parallelly measures the inter-frequencies of the carrier in the carrier aggregation in the measurement gap according to the measurement configuration information. The measurement configuration information includes information about the inter-frequencies of the carrier in the carrier aggregation.
In this embodiment, optionally, the base station sends a radio resource control RRC reconfiguration message to the UE, and the RRC reconfiguration message carries the measurement configuration information that is sent by the base station according to the indication information and that is of the inter-frequencies of the carrier in the carrier aggregation.

The transceiver 1501 is further configured to send the measurement configuration information determined by the processor 1502 to the UE.
Optionally, when sending the measurement configuration information determined by the processor 1502 to the UE, the transceiver 1501 is specifically configured to:
In this embodiment, the UE sends, to the base station, the indication information used to indicate that the UE supports the parallel measurement performed on the inter-frequencies of the carrier in the carrier aggregation. The base station determines the measurement configuration information of the inter-frequencies of the carrier in the carrier aggregation of the UE according to the indication information, and then the base station sends the measurement configuration information to the UE. The UE parallelly measures the inter-frequencies of the carrier in the carrier aggregation in the measurement gap according to the measurement configuration information. The measurement configuration information includes the information about the inter-frequencies of the carrier in the carrier aggregation. Therefore, the UE can parallelly measure all inter-frequencies in the carrier aggregation supported by the UE, so as to prevent the UE from parallelly measuring, in an existing measurement mechanism, only three inter-frequencies in the carrier aggregation supported by the UE. According to the technical method in this embodiment, a quantity of inter-frequencies that are in the carrier aggregation supported by the UE and that are parallelly measured by the UE can be increased.
