Background

The main process of the terminal for carrying out cell Handover comprises the following steps: handover preparation, handover execution, and handover completion. The terminal needs to report the wireless access capability to the network during the preparation of the handover, and then the network performs wireless resource allocation according to the capability of the terminal. In the third generation partnership project (3rd Generation Partnership Project,3GPP) mobility enhancement project, an optimization method for reducing the interruption time at the time of handover is proposed, which comprises the following two architectures: 1. the double connection (Dual Connectivity, DC), when switching, add the goal base station as the auxiliary Node (SN) first, then change SN into the Master Node (MN) through the roll change signaling, release the source base station finally, thus achieve the effect that the interrupt time reduces while switching; 2. and based HO and eMBB based HO, when the terminal receives a HO command, continuing to keep the connection with the source base station and initiate random access to the target base station at the same time, and releasing the connection of the source base station until the terminal and the target base station are accessed, wherein a dual-activation protocol stack (dual active protocol stack, DAPS) architecture is adopted, and the protocol stacks of the source cell and the target cell and data transceiving are simultaneously maintained in the switching process.

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

The network device is used for providing communication service for the terminal and accessing the core network, and the terminal can access the network by searching for synchronous signals, broadcast signals and the like sent by the network device, so as to perform communication with the network. The terminal 1 in fig. 1 establishes a link 1 with a network device, and the terminal 1 may perform uplink and downlink transmission with the network device.

Currently, reporting about terminal capability of CA/DC mainly relates to band combination capability of a terminal, specifically, for a specific band combination, the terminal further indicates whether asynchronous DC is supported, and indicates division from different bands (bands) to different cell groups through supportedCellGrouping, where a specific description in a protocol is defined as follows:

Regarding specific cell group partitioning, taking the combination of 3 bands as an example, if the indicated pattern is 010, i.e. band1 and band3 correspond to 0 and band2 corresponds to 1, it means that among these three bands, the terminal supports aggregation of band1 and band3 to one cell group, while band2 can be allocated to another cell group, and since 010 is equivalent to 101, there is no entry of 101 in table 1.

Table 1 band division table

Currently, only the band combination capability of the terminal is defined for CA/DC, and the division from different bands (bands) to different cell groups (cell groups) is indicated in the dual-connection band indication capability, but the same band cannot be divided into two cell groups at the same time. The handoff scenario for the dual active protocol stack (DAPS: dual active protocol stack) may be an internal inter-band handoff, or an inter-band handoff. But the existing band combination capability indicates that the scenario to DAPS INTRA-band handover cannot be used.

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

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

step 201, reporting band combining capability indication information by a terminal;

step 202, the source base station acquires the band combining capability indication information reported by the terminal.

The band combination capability indication information uploaded by the terminal is used for indicating at least one first band combination, each first band combination in the at least one first band combination comprises at least one band supporting intra-band switching in a dual-active protocol stack DAPS band, and the DAPS INTRA-band switching refers to that the terminal communicates with a source base station and a target base station simultaneously on the same band in the DAPS switching process. That is, the terminal indicates, in the band combining capability report, a band combination including at least one band that can be simultaneously operated at the source base station and the target base station.

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 including a first field for indicating that the corresponding band supports DAPS INTRA-band handover.

For example, one band combination includes band1, band2 and band3, and the terminal reports the time indication, where band1 and band3 may be aggregated under the source base station, and band2 may operate under the source base station and the target base station at the same time, 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, band1, band2, band3, and the terminal communicates with the target base station in band2, where the indication of band2 where this support is to operate simultaneously under different base stations may be indicated by a special first field.

The method is characterized in that in signaling design, the terminal can indicate whether the band support is simultaneously operated under different base stations through a special field in the dual-activation protocol stack DAPS capability indication. For example:

In the table of SupportedCellGrouping, a special field, for example, x, is introduced, which is different from 0 and 1, to indicate that the band corresponding to the special field can operate under the source base station and the target base station at the same time. Table 2 exemplifies a combination of 3 bands, a combination 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 band2 to be simultaneously allocated to two different cell groups, and supports aggregation of band1 and band3 to one cell group, that is, indicates that the corresponding band2 supports DAPS INTRA-band handover through field x.

In this example, the band combination capability indication information reported by the terminal includes a first indication field for each first band combination, where the first indication field includes a first field, where the first field is used to indicate that the corresponding band supports DAPS INTRA-band switching, and the first field indicates that the band supporting DAPS INTRA-band switching is used, so that the source base station can successfully configure the band combination for DAPS INTRA-band switching according to the capability indication information, which is beneficial to improving the configuration success rate of band resources in DAPS switching and improving throughput in DAPS switching.

In one possible example, the band combining capability indication information further includes a second indication field for the target band indicated by the first field, the second indication field being used to indicate at least one carrier element CC or carrier aggregation bandwidth type CA-bandwidth class of the target band supporting DAPS INTRA-band handover.

The first field in the capability indication information reported by the terminal indicates that the corresponding frequency band supports DAPS INTRA-band switching, and further indicates, for the frequency band supporting DAPS INTRA-band switching, which carrier units (Component Carrier, CCs) or carrier aggregation bandwidth types CA-bandwidth types in the frequency band can support the terminal to simultaneously communicate with the first base station and the second base station, while those CCs in the frequency band which do not support to simultaneously operate under two different base stations can only operate under one base station alone.

The carrier aggregation CA means that resources on multiple carrier units are jointly scheduled and used, so that a New Radio access (NR) system can support a larger bandwidth, and a higher system peak rate can be achieved.

In this example, the band combination capability indication information reported by the terminal may further include 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 unit CC or a carrier aggregation bandwidth type CA-bandwidth class of the target band to support DAPS INTRA-band handover, and the second indication field specifically indicates which carrier units in a specific band may work under two base stations at the same time, or which carrier aggregation bandwidth types may support the terminal to communicate with different base stations at the same time, so that the source base station may successfully configure the band combination according to the capability indication information reported by the terminal, which is favorable to improving the configuration success rate of the band resources in DAPS handover, and saving the time of DAPS handover.

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

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

In this example, the terminal may report the band combination capability indication information, where the capability indication information reported by the terminal includes a first indication field for indicating at least one second band combination of the terminal in communication with the first base station in the synchronization mode and a second indication field for indicating at least one third band combination of the terminal in communication 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 two different base stations simultaneously, and the source base station configures the band combinations according to the capability indication information reported by the terminal, which is favorable for saving DAPS handover time and improving DAPS handover efficiency.

In one possible example, the at least one first band combination is a band combination that includes the same band of the first set of band combinations and the second set of band combinations, the first set of band combinations including the at least one second band combination, the second set of band combinations including the at least one third band combination, the same band being a band of the at least one band.

In a specific implementation, at least the first band combination is a band combination including the same band in two band combination sets, and the two band combination sets respectively include at least one second band combination and at least one third band combination, where the second band combination and the third band combination may partially overlap or may be completely different, and if the second band combination and the third band combination partially overlap, i.e. include the same band, where the same band is a band supporting intra-band switching in a dual-active protocol stack DAPS band, the second band combination and the third band combination may be the at least one first band combination.

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 in a dual-active protocol stack DAPS band, where the at least one first band combination is a band combination including 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 supported by two different base stations, where the band combinations 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 favorable for improving configuration rationality of band resources in DAPS handover.

In one possible example, the band combining 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 during the DAPS handover; 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 a specific implementation, in DAPS handover, if carrier aggregation under only one frequency band is limited under one base station, the band combining capability of the terminal may indicate, for each single frequency band operating under a certain base station, a band combination that can be aggregated under another base station, capability indication information reported by the terminal, a single frequency band under one base station, and a band combination under another base station.

In this example, the terminal reports the meeting frequency band combination capability indication information, where the frequency band combination capability indication information includes an indication field for indicating a single frequency band of the terminal that is in communication with the first base station in the synchronous mode and an indication field for indicating at least one second frequency band combination of the terminal that is in communication with the second base station in the synchronous mode, where the terminal indicates the single frequency band under one base station and the frequency band combination under another base station, so that the source base station can configure the frequency band combination according to the capability indication information, which is beneficial to improving the configuration success rate of the frequency band resources 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 includes the at least one first combination of frequency bands including the single frequency band.

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

It can be seen that, in this example, if carrier aggregation under only one frequency band is limited under one base station, the terminal reports the capability of frequency band combination, indicates, for each frequency band supporting terminal under one base station to simultaneously communicate with two base stations, to support a frequency band combination polymerizable under another base station, where the frequency band combination includes a frequency band combination including a frequency band supporting the terminal to simultaneously communicate with two base stations, and the terminal reports capability indication information indicating the above frequency band combination, so that the source base station can successfully configure the 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 DAPS handover.

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

In a specific implementation, the band combination capability indication information may further indicate a band combination including only the 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 one band at the same time.

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

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

The terminal sends the band combining 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 source base station acquires the band combining capability indication information reported by the terminal, and the band combining capability indication information comprises:

the source base station receives the band combining 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 band combining 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 band combining capability indication information sent by the terminal, or may receive the band combining capability indication information forwarded by the target base station from the terminal, and then perform radio resource configuration according to the band combining capability indication information.

In this example, the terminal may send the capability indication information of the band combination in any of the foregoing method examples to at least one network device, 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 supporting intra-band handover in a dual-active protocol stack DAPS band, and the DAPS INTRA-band handover refers to that the terminal communicates with the source base station and the target base station simultaneously on the same band in the DAPS handover process, so that the source base station can directly or indirectly receive the capability indication information of the band combination sent by the terminal, and then the source base station can successfully configure the band combination for DAPS INTRA-band handover according to the capability indication information, which is beneficial to improving the configuration success rate of the band resources in the DAPS handover.

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

The terminal receives the 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 combining capability indication information reported by the terminal, the method further comprises the following steps:

the source base station generates frequency band combination configuration information; and the source base station sends the frequency band combination configuration information to the terminal, wherein the frequency band combination configuration information is used for the terminal to execute the DASP switching.

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

In this example, after the terminal reports the band combining capability indication information, the source base station obtains the band combining capability indication information, and then generates the band combining configuration information received by the terminal, and after the terminal receives the configuration information, the DASP handover is performed according to the band combining configuration information.
