Description

Terminal capability reporting method, method for acquiring terminal capability and related device

Technical Field

The present application relates to the field of communications technologies, and in particular, to a method for reporting a terminal capability, a method for acquiring a terminal capability, and a related apparatus.

Background

The main process of the terminal for carrying out cell Handover includes: handover preparation, handover execution, and handover completion. When the handover is prepared, the terminal needs to report the radio access capability to the network, and then the network performs radio resource configuration according to the capability of the terminal. In the 3rd Generation Partnership Project (3 GPP) mobility enhancement topic, an optimization method for reducing the interruption time during handover is proposed, which includes the following two architectures: 1. dual Connectivity (DC), in handover, a target base station is added as a Secondary Node (SN), then the SN is changed into a Master Node (MN) through role change signaling, and finally a source base station is released, thereby achieving an effect of reducing the interruption time during handover; 2. the terminal continuously keeps connection with a source base station and simultaneously initiates random access to a target base station when receiving an HO command (switching instruction), and the connection of the source base station is not released until the terminal is completely accessed with the target base station, wherein a Dual Active Protocol Stack (DAPS) architecture simultaneously maintains protocol stacks of a source cell and a target cell and receives and transmits data in the switching process.

Carrier Aggregation (CA) can be classified into continuous Carrier Aggregation and non-continuous Carrier Aggregation according to continuity of aggregated carriers over a frequency spectrum; and dividing into internal Intra-band carrier aggregation and inter-band carrier aggregation according to whether the bands (frequency bands) where the aggregated carriers are located are the same. On the basis of carrier aggregation, a terminal may simultaneously communicate with two base stations through Dual Connectivity (DC).

Currently, terminal capability reporting related to CA/DC mainly relates to the band combination capability of a terminal, specifically, for a specific band combination, the terminal further indicates whether to support asynchronous DC, and indicates the division of different bands into different cell groups through supported cell grouping, and specific descriptions in the protocol are defined as follows:

regarding the specific cell group division, taking the combination of 3 bands as an example, if the indicated pattern is 010, that is, band1 and band3 correspond to 0, and band2 corresponds to 1, it means that in the three bands, the terminal supports the aggregation of band1 and band3 to one cell group, and band2 can be allocated to another cell group, and since 010 is equal to 101, there is no 101 in table 1.

Table 1 band division table

Currently, the band combination capability of a terminal is defined only for CA/DC, and the division of different bands into different cell groups is indicated in the dual connectivity band indication capability, but the same band cannot be divided into two cell groups at the same time. The switching scene of the Dual Active Protocol Stack (DAPS) can be internal inter-band switching and can be inter-band switching. But the existing band combining capability indicates that scenarios to DAPS intra-band handover cannot be used.

In view of the above problems, an embodiment of the present application provides a method for reporting a terminal capability, which is described in detail below with reference to the accompanying drawings.

Referring to fig. 2, fig. 2 is a schematic flow chart of a method for reporting terminal capability according to an embodiment of the present application, and as shown in the figure, the method includes:

step 201, a terminal reports band combination capability indication information;

step 202, the source base station obtains the band combination capability indication information reported by the terminal.

The method comprises the steps that frequency band combination capability indication information uploaded by a terminal is used for indicating at least one first frequency band combination, each first frequency band combination in the at least one first frequency band combination comprises at least one frequency band supporting intra-band handover in a DAPS (dual activation protocol stack), and the DAPS intra-band handover refers to the fact that the terminal is simultaneously communicated with a source base station and a target base station on the same frequency band in the DAPS handover process. That is, the terminal indicates, in the reporting of the band combination capability, a band combination including at least one band that can operate in the source base station and the target base station simultaneously.

In one possible example, the band combination capability indication information includes a first indication field for each of the first band combinations, the first indication field includes a first field for indicating that the corresponding band supports DAPS intra-band handover.

For example, one band combination includes band1, band2, and band3, the terminal indicates in uplink, band1 and band3 may be aggregated under the source base station, and band2 may operate under both the source base station and the target base station, so that the capability indication of the terminal supports the following band combination configuration in DAPS handover: the terminal communicates with the source base station in three bands of band1, band2 and band3, and the terminal communicates with the target base station in band2, wherein to indicate this support for band2 operating simultaneously in different base stations, it can be indicated by a special first field.

Embodied in signaling design, the terminal may indicate whether a band supports simultaneous operation under different base stations through a special field in the dual activation protocol stack DAPS capability indication. For example:

in the supported cell grouping table, a special field, for example, x, is introduced, which is different from 0 and1, and is used to indicate that the band corresponding to the special field can simultaneously operate under the source base station and the target base station. Table 2 exemplifies combinations of 3 bands, combinations of 4 bands and 5 bands, and so on.

Table 2 band division table

For example, the indicated pattern is 0x0, that is, band1 corresponds to 0, band2 corresponds to x, and band3 corresponds to 0, which means that the terminal supports that band2 is simultaneously allocated to two different cell groups, and that band1 and band3 are aggregated to one cell group, that is, it is indicated by field x that the corresponding band2 supports DAPS intra-band handover.

It can be seen that, in this example, the frequency band combination capability indication information reported by the terminal includes a first indication field for each first frequency band combination, where the first indication field includes a first field, and the first field is used to indicate that a corresponding frequency band supports DAPS intra-band handover, and indicate, through the first field, a frequency band supporting DAPS intra-band handover, so that the source base station may successfully configure the frequency band combination for DAPS intra-band handover according to the capability indication information, which is beneficial to improving a configuration success rate of a frequency band resource in DAPS handover and improving throughput in a DAPS handover process.

In one possible example, the band combination capability indication information further includes a second indication field for the target band indicated by the first field, where the second indication field is used to indicate at least one carrier component CC or carrier aggregation bandwidth type CA-bandwidth class that the target band supports DAPS intra-band handover.

In the capability indication information reported by the terminal, a first field indicates that a corresponding frequency band supports DAPS intra-band handover, and further indicates which Carrier units (CCs) or Carrier aggregation bandwidth types CA-band in the frequency band can support the terminal to simultaneously communicate with a first base station and a second base station for the frequency band supporting DAPS intra-band handover, and the frequency band does not support CCs which simultaneously operate under two different base stations, and can only individually operate under one of the base stations.

The CA refers to jointly scheduling and using resources on multiple carrier units, so that a New Radio access (NR) system can support a larger bandwidth, thereby achieving a higher peak rate of the system.

It can be seen that, in this example, the frequency band combination capability indication information reported by the terminal further includes a second indication field for the target frequency band indicated by the first field, where the second indication field is used to indicate at least one carrier component CC or carrier aggregation bandwidth type CA-bandwidth class that the target frequency band supports DAPS intra-band handover, and the second indication field specifically indicates which carrier components in a specific frequency band can simultaneously operate under two base stations or which carrier aggregation bandwidth types can support the terminal to simultaneously communicate with different base stations, so that the source base station can successfully configure the frequency band combination according to the capability indication information reported by the terminal, which is beneficial to improving the configuration success rate of the frequency band resource in the DAPS handover and saving the time of the DAPS handover.

In one possible example, the band combination capability indication information includes a first indication field and a second indication field, the first indication field is used for indicating at least one second band combination of the terminal communicating with a first base station in a synchronous mode, the second indication field is used for indicating at least one third band combination of the terminal communicating with a second base station in the synchronous mode, and the synchronous mode is that the terminal communicates with the source base station and the target base station simultaneously in the DAPS handover process; the first base station is the source base station, and the second base station is the target base station; or, the first base station is a target base station, and the second base station is a source base station.

In the present embodiment, the existing CA band combination is applied in the synchronization mode, and may be understood as a band combination supported by one base station, and on this basis, a band combination supported by another base station is added for DAPS handover, that is, band combination capability indication information reported by a terminal simultaneously indicates a band combination supported by each of two different base stations, and the terminal simultaneously communicates with the source base station and the target base station during the DAPS handover, where the two band combinations may partially overlap or may be two completely different band combinations.

It can be seen that, in this example, the terminal may report band combination capability indication information, where the capability indication information reported by the terminal includes a first indication domain for indicating at least one second band combination in which the terminal communicates with the first base station in the synchronization mode, and a second indication domain for indicating at least one third band combination in which the terminal communicates with the second base station in the synchronization mode, where the synchronization mode is that the terminal communicates with the source base station and the target base station simultaneously in the DAPS handover process, the terminal indicates the band combinations supported by the two different base stations at the same time, and the source base station configures the band combinations according to the capability indication information reported by the terminal, which is beneficial to saving DAPS handover time and improving DAPS handover efficiency.

In one possible example, the at least one first frequency band combination is a frequency band combination containing the same frequency band in a first frequency band combination set and a second frequency band combination set, the first frequency band combination set includes the at least one second frequency band combination, the second frequency band combination set includes the at least one third frequency band combination, and the same frequency band is a frequency band in the at least one frequency band.

In a specific implementation, at least the first frequency band combination is a frequency band combination containing the same frequency band in two frequency band combination sets, and the two frequency band combination sets respectively include at least one second frequency band combination and at least one third frequency band combination, the second frequency band combination and the third frequency band combination may be partially overlapped or completely different, and if the second frequency band combination and the third frequency band combination have partial overlap, that is, contain the same frequency band, where the same frequency band is a frequency band supporting intra-band handover within a DAPS frequency band of a dual activation protocol stack, the second frequency band combination and the third frequency band combination may be the at least one first frequency band combination.

It can be seen that, in this example, the band combination capability indication information reported by the terminal indicates at least one first band combination, where the at least one first band combination includes at least one band supporting intra-band handover within a DAPS band of a dual activation protocol stack, where the at least one first band combination is a band combination that includes the same band in a first band combination set and a second band combination set, the same band is a band in the at least one band, the two band combination sets each include a band combination that is supported by two different base stations, the band combinations that are supported by the two different base stations may partially overlap or may be completely different, and the source base station configures the band combination according to the combination capability indication information reported by the terminal, which is beneficial to improving configuration rationality of band resources in DAPS handover.

In one possible example, the band combination capability indication information includes a first indication field for indicating a single band in which the terminal communicates with a first base station in a synchronization mode, and a second indication field for indicating at least one second band combination in which the terminal communicates with a second base station in the synchronization mode, the synchronization mode being that the terminal communicates with a source base station and a target base station simultaneously in the DAPS handover procedure; the first base station is a source base station, and the second base station is a target base station; or, the first base station is a target base station, and the second base station is a source base station.

In the implementation, in the DAPS handover, if carrier aggregation is restricted to be configured only in one frequency band under one of the base stations, the frequency band combination capability of the terminal may indicate a frequency band combination that can be aggregated under another base station for each single frequency band operating in one base station, and the capability indication information reported by the terminal indicates the single frequency band under one base station and the frequency band combination under another base station.

It can be seen that, in this example, the terminal reports band combination capability indication information, where the band combination capability indication information includes an indication field for indicating a single band in which the terminal communicates with the first base station in the synchronization mode and an indication field for indicating at least one second band combination in which the terminal communicates with the second base station in the synchronization mode, and the terminal indicates the single band in one base station and the band combination in another base station, so that the source base station may configure the band combination according to the capability indication information, which is beneficial to improving the configuration success rate of the band resource in the DAPS handover.

In one possible example, the at least one frequency band is the single frequency band; the at least one second combination of frequency bands comprises the at least one first combination of frequency bands that includes the single frequency band.

In a specific implementation, a single frequency band in which the terminal communicates with one base station in the synchronization mode is a frequency band supporting intra-band handover within a DAPS frequency band of a dual activation protocol stack, and the DAPS capability of the terminal may indicate, for each of the single frequency bands, that a frequency band combination that can be aggregated under another base station is supported, where the frequency band combination includes the single frequency band.

It can be seen that, in this example, if carrier aggregation is limited to be configured only under one base station under one frequency band, the terminal reports the frequency band combination capability, and indicates, for each frequency band supporting the terminal under one base station to communicate with two base stations at the same time, a frequency band combination capable of being aggregated under another base station is supported, where the frequency band combination includes a frequency band combination including frequency bands supporting the terminal to communicate with two base stations at the same time, and the terminal reports capability indication information indicating the above frequency band combination, so that the source base station can successfully configure a frequency band combination for DAPS intra-band handover according to the capability indication information, which is beneficial to improving the configuration success rate of frequency band resources in DAPS handover and improving throughput in the DAPS handover process.

In one possible example, the band combination capability indication information is further used for indicating at least one third band combination, each of the at least one third band combination including only a band supporting DAPS inter-band handover.

In a specific implementation, the band combination capability indication information may further indicate a band combination including only bands supporting inter-band handover between DAPS bands, that is, each band in the band combination supports the terminal to communicate with different base stations on the same band.

It can be seen that, in this example, the frequency band combination capability information reported by the terminal is further used to indicate at least one third frequency band combination, and each third frequency band combination in the at least one third frequency band combination only includes a frequency band supporting inter-band handover between DAPS frequency bands, so that the source base station can successfully configure the frequency band combination for the inter-band handover of DAPS according to the capability indication information, which is beneficial to improving the configuration success rate of frequency band resources in the DAPS handover and saving the DAPS handover time.

In one possible example, the reporting, by the terminal, band combination capability indication information includes:

and the terminal sends the band combination capability indication information to at least one network device, wherein the at least one network device comprises the source base station and/or the target base station.

The method for acquiring the frequency band combination capability indication information reported by the terminal by the source base station includes:

the source base station receives the frequency band combination capability indication information sent by the terminal; or, the source base station receives the band combination capability indication information forwarded by the target base station from the terminal.

The terminal may communicate with the source base station and/or the target base station, may send the frequency band combination capability indication information in the foregoing method examples to the source base station and/or the target base station, and the source base station may directly receive the frequency band combination capability indication information sent by the terminal, or may receive the frequency band combination capability indication information from the terminal forwarded by the target base station, and then perform radio resource configuration according to the frequency band combination capability indication information.

It can be seen that, in this example, the terminal may send, to at least one network device, the band combination capability indication information in any of the foregoing method examples, where the capability indication information is used to indicate at least one first band combination, where each first band combination in the at least one first band combination includes at least one band that supports intra-band handover within a DAPS band of a dual activation protocol stack, and DAPS intra-band handover refers to that the terminal communicates with a source base station and a target base station on the same band simultaneously in a DAPS handover process, so that the source base station can directly or indirectly receive the band combination capability indication information sent by the terminal, and then the source base station can successfully configure a band combination for DAPS intra-band handover according to the capability indication information, which is beneficial to improve a configuration success rate of a band resource in DAPS handover.

In a possible example, after the terminal reports the band combination capability indication information, the method further includes:

the terminal receives frequency band combination configuration information; and the terminal executes DASP switching according to the frequency band combination configuration information.

After the source base station obtains the band combination capability indication information reported by the terminal, the method further includes:

the source base station generates frequency band combination configuration information; the source base station sends the band combination configuration information to the terminal, where the band combination configuration information is used for the terminal to perform the DASP handover.

Wherein the band combination indicated by the band combination configuration information at least comprises a first frequency band, and the first frequency band is a frequency band of the at least one frequency band.

It can be seen that, in this example, after the terminal reports the band combination capability indication information, and the source base station obtains the band combination capability indication information, the source base station generates the terminal receiving band combination configuration information, and after the terminal receives the configuration information, the terminal performs DASP handover according to the band combination configuration information.
