Technical field

This application relates to the field of communication technology, and in particular to a communication method, device and chip.

Background technique

In the prior art, the terminal implements processes such as cell access, cell handover, or cell reselection through cell measurement. One way to measure is to measure in the gap. For example, the terminal can interrupt data transmission and reception with the serving cell in the gap to perform neighbor cell measurement. However, the terminal interrupts the data transmission and reception between the terminal and the serving cell in the gap, which will have a greater impact on the throughput. Therefore, it is proposed in LTE that the terminal can support a combination of different frequencies, that is, the terminal has multiple radio frequency channels, and different radio frequency channels support different frequencies. The terminal does not need to interrupt the data transmission and reception with the serving cell, and can also perform neighbor cell measurement through other radio frequency channels without affecting the serving cell. Therefore, the network side does not need to configure gaps for such terminals, or that such terminals have no gap capability.

Currently, there is no relevant solution for the terminal to report that it has no gap capability.

Summary of the invention

This application provides a communication method, device, and chip to provide a way for the terminal to report the no gap capability.

In the first aspect, a communication method is provided, which can be implemented by a communication device. For example, the communication device may be a terminal device. Wherein, when the communication device determines that it has the no GAP capability without gaps, it may indicate to the network equipment that the communication device has the no GAP capability through terminal capability signaling, a cell handover request, or an RRC reconfiguration complete message.

Therefore, the embodiments of the present application provide a way for the terminal device to report the no GAP capability, so that the network device can be configured based on the no GAP capability of the terminal device. For example, when the network device determines that the terminal device has no GAP capability, it may not be necessary to configure the gap for the terminal device, which saves transmission resources.

The manner in which the terminal reports the no GAP capability may include at least one of the following manners.

Manner 1: The communication device instructs the network equipment communication device to have no GAP capability through terminal capability signaling. For example, the communication device sends terminal capability signaling to the network device, where the terminal capability signaling is used to instruct the network device to indicate to the target network device that the communication device has no GAP capability.

For example, when the terminal is in an idle state, when the terminal reconnects to the serving cell, it can actively or passively send the terminal capability signaling to the serving cell, that is, report the no gap capability through the terminal capability signaling, so that the serving cell can be based on the no GAP of the terminal device Ability to configure. For example, when the serving cell determines that the terminal device has no GAP capability, there may be no need to configure the gap for the terminal device, saving transmission resources.

In method 1, the terminal capability signaling can indicate that the terminal has no GAP capability in an explicit or implicit manner. For example, the terminal capability signal does not include GAP configuration information (that is, implicit indication); for another example, the terminal capability signaling carries first indication information, and the first indication information is used to indicate that the communication device has no GAP Ability (that is, explicit indication).

Manner 2: The communication device indicates to the network equipment that the communication device has no GAP capability through a cell handover request. For example, the communication apparatus sends a cell handover request to the network equipment, where the cell handover request is used to instruct the network equipment to indicate to the target network equipment that the communication apparatus has no GAP capability.

For example, when the terminal determines that it needs to switch from the serving cell to the target cell, it can implement cell switching through a cell switching request and report the no gap capability to the serving cell so that the serving cell can be configured based on the no GAP capability of the terminal device. For example, when the serving cell determines that the terminal device has no GAP capability, there may be no need to configure the gap for the terminal device, saving transmission resources.

In method 2, the cell handover request can indicate that the terminal has no GAP capability in an explicit or implicit manner. For example, the cell handover instruction does not include GAP configuration information (that is, implicit indication); for another example, the cell handover request carries second indication information, and the second indication information is used to indicate that the communication device has no GAP Ability (that is, explicit indication).

Manner 3: The communication device indicates to the network equipment that the communication device has no GAP capability through the RRC reconfiguration complete message. For example, after the communication device switches from the network device to the target network device, it sends an RRC reconfiguration complete message to the target network device, where the RRC reconfiguration complete message is used to indicate that the communication device has no GAP capability.

For example, after the terminal switches from the serving cell to the target cell, the RRC reconfiguration complete message can be used to instruct the network equipment terminal to complete the cell switching and report the no gap capability to the target cell so that the target cell can be configured based on the no GAP capability of the terminal device. For example, when the target cell determines that the terminal device has no GAP capability, there may be no need to configure the gap for the terminal device, saving transmission resources.

In method 3, the RRC reconfiguration complete message can indicate that the terminal has no GAP capability in an explicit or implicit manner. For example, the RRC reconfiguration complete message does not include GAP configuration information (ie, implicit indication); and/or, the RRC reconfiguration complete message carries third indication information, and the third indication information is used to indicate the The communication device has no GAP capability (that is, explicit indication).

In a possible design, the communication apparatus may also send fourth indication information to the network device, where the fourth indication information is used to indicate that the communication apparatus supports one or more frequency combinations of no GAP capability, and The one or more frequency combinations are all frequency combinations for which the terminal supports No GAP capability, or one or more frequency combinations supported by the network device in the all frequency combinations.

For example, after the terminal reports to the network device that the terminal supports a frequency combination of no GAP capabilities (for example, frequency 1 and frequency 2), the network device can be configured based on the frequency combination. For example, the network device can configure the terminal to use frequency 1 for data transmission with the network device, and configure the terminal to use frequency 2 for neighboring cell measurement. Therefore, the network device does not need to allocate gaps for the terminal, saving transmission resources.

In a possible design, the communication device may also receive a query request sent by the network device before indicating to the network device that the communication device has no GAP capability through terminal capability signaling, a cell handover request, or an RRC reconfiguration complete message The query request is used to request to query the no GAP capability of the communication device.

The terminal can actively or passively report the no GAP capability to the network device, which is not limited in the embodiment of this application.

In the embodiment of the present application, the network device is a network device under a first communication system, the target network device is a network device under a second communication system, and the first communication system is an LTE system, an EPC system, or In a 5G system, the second communication system is an LTE system, an EPC system, or a 5G system.

In the embodiment of the present application, the terminal may report the no GAP capability to the serving cell and/or the target cell during the process of handover from the serving cell to the target cell. The serving cell and the target cell here may be cells under the same communication system, or may be cells under different communication systems, which are not limited in the embodiment of the present application.

In the second aspect, a communication method is also provided, which is implemented by a communication device. The communication device is, for example, a network device. The communication device receives a first message, the first message is used to indicate that the terminal has no GAP capability, and the first message includes terminal capability signaling, a cell handover request, or an RRC reconfiguration complete message; based on the first message Perform resource allocation.

Therefore, the embodiments of the present application provide a way for the terminal device to report the no GAP capability, so that the network device can make a decision based on the no GAP capability of the terminal device. For example, when the network device determines that the terminal device has no GAP capability, there is no need to allocate gaps to the terminal device, saving transmission resources.

Example 1: The first message is terminal capability signaling, that is, the communication device receives terminal capability signaling from the terminal, and the terminal capability signaling is used to instruct the communication device to indicate to the target communication device that the terminal has no GAP capability.

Wherein, the terminal capability signaling does not include GAP configuration information; and/or, the terminal capability signaling carries first indication information, and the first indication information is used to indicate that the terminal has no GAP capability.

Example 2: The first message is a cell switching request, that is, the communication device receives a cell switching request from the terminal or the communication device currently accessed by the terminal, and the cell switching request is used to instruct the communication device to communicate with the target The device indicates that the terminal has no GAP capability.

Wherein, the cell handover request does not include GAP configuration information; and/or, the cell handover request carries second indication information, and the second indication information is used to indicate that the terminal has no GAP capability.

Example 3: The first message is an RRC reconfiguration complete message, that is, the communication device receives an RRC reconfiguration complete message from the terminal, and the RRC reconfiguration complete message is used to indicate that the terminal has no GAP capability.

Wherein, the RRC reconfiguration complete message does not include GAP configuration information; and/or, the RRC reconfiguration complete message carries third indication information, and the third indication information is used to indicate that the terminal has no GAP ability.

In a possible design, the communication device may also receive fourth indication information, where the fourth indication information is used to indicate that the terminal supports one or more frequency combinations of no GAP capability, and the one or more frequency combinations All frequency combinations that support No GAP capability for the terminal, or one or more frequency combinations supported by the network device in the all frequency combinations.

It also includes restricted devices, such as devices with low power consumption, or devices with limited storage capabilities, or devices with limited computing capabilities. Examples include barcodes, radio frequency identification (RFID), sensors, global positioning system (GPS), laser scanners and other information sensing equipment.

As an example and not a limitation, in the embodiment of the present application, the terminal may also be a wearable device. Wearable devices can also be called wearable smart devices or smart wearable devices, etc. It is the general term for the application of wearable technology to intelligently design daily wear and develop wearable devices, such as glasses, gloves, watches, bracelets, Clothing and shoes, etc. A wearable device is a portable device that is directly worn on the body or integrated into the user's clothes or accessories. Wearable devices are not only a kind of hardware device, but also realize powerful functions through software support, data interaction, and cloud interaction.

The various terminals described above, if they are located on a vehicle (for example, placed in a vehicle or installed in a vehicle), can be regarded as a vehicle-mounted terminal. The vehicle-mounted terminal is, for example, also called an on-board unit (OBU).

3) Resources, which can also be referred to as transmission resources, include any one or a combination of time domain resources, frequency domain resources, time-frequency resources, or space domain resources.

4) Time unit. The time domain resource includes one or more time units. The time unit can be a radio frame, subframe, time slot, symbol, etc. Among them, one radio frame may include multiple subframes, one subframe may include one or more time slots (slot), and one time slot may include at least one symbol (symbol). Alternatively, one radio frame may include multiple time slots, and one time slot may include at least one symbol.

5) Gap, including one or more time units. The gap can be pre-configured or dynamically configured on the network side. In the embodiment of the present application, the no gap (no gap) capability of the terminal may be the measurement of the terminal not based on the gap, and therefore, there is no need to configure the gap. Among them, the no gap capability of the terminal can be expressed as need for gap capability is invalid; or don ^, t need for gap capability.

6) Radio resource control (RRC). In LTE, two RRC states are supported, namely RRC idle state (RRC_IDLE) and RRC connected state (RRC_CONNECTED). In NR, the RRC inactive state (RRC_INACTIVE) is introduced, that is, three states are supported in NR, RRC idle state (RRC_IDLE), RRC inactive state (RRC_INACTIVE), and RRC connected state (RRC_CONNECTED), as shown in Figure 1. Among them, different RRC states can be switched. For example, when the UE is in the RRC_IDLE state, it can switch to the RRC_CONNECTED state by establishing a connection mechanism, and then fall back to the RRC_IDLE state by releasing the connection mechanism. The UE is in the RRC_CONNECTED state, and can switch to RRC_INACTIVE through the Release with Suspend connection mechanism, and then back to the RRC_CONNECTED state through the Resume connection mechanism. When the UE is in the RRC_INACTIVE state, it can switch to the RRC_IDLE state through the Release connection mechanism.

7) The mobility management mechanism of the terminal, through cell handover or cell reselection with different coverage areas, so as to obtain continuous service of the wireless network. There are many scenarios for cell handover or reselection. For example, scenario 1, after the terminal is connected to the current serving cell, the location of the terminal moves. For example, when the terminal is far away from the current serving cell, the terminal may need to perform cell handover or cell reselection. . Scenario 2: When the service quality of the cell currently serving the terminal is poor (for example, the signal strength is low), the terminal may perform cell handover or cell reselection to access a neighboring cell with better signal. The current serving cell here is a cell currently serving the terminal, and a neighboring cell can be understood as a cell other than the serving cell where the terminal can search for signals in the serving cell.

For example, when the terminal is in the RRC_IDLE state and the RRC_INACTIVE state, there is no RRC link with the current serving cell. When the signal quality of the serving cell where the terminal resides is lower than a certain threshold, the neighbor cell measurement can be performed to measure the signal quality of the neighbor cell. If the signal quality meets the condition, it will switch to the neighbor cell and camp in the neighbor cell. When the terminal is in the RRC_IDLE state and the RRC_INACTIVE state, the process of switching from the serving cell to other cells is a cell reselection process.

For another example, when the terminal is in the RRC_CONNECTED state, there is an RRC connection between the terminal and the current serving cell. The current serving cell can configure the terminal to perform neighbor cell measurement through RRC signaling. The terminal reports the measurement result of the neighboring cell to the serving cell, and the serving cell switches the terminal to a cell with better signal quality according to the measurement result. When the terminal is in the RRC_CONNECTED state, the process of switching from the serving cell to the neighboring cell is a cell handover (Handover) process.

It is understandable that the above cell reselection or cell handover processes are all performed based on the measurement results of neighboring cells.

8) Neighboring cell measurement. A terminal camping in the current serving cell can measure related information (such as signal quality) of the neighboring cell to serve as a basis for cell handover or cell renewal. The currently supported neighbor cell measurement mechanisms include the following two mechanisms. Measurement mechanism 1: Gap-based measurement. In the gap, the terminal interrupts the reception and transmission of data with the serving cell, and performs neighbor cell measurement.

Taking the above scenario 2 as an example, the user carries the terminal within the range of cell 1, and the terminal resides in cell 1. Assuming that the signal strength of cell 1 is less than a preset value (which can be a pre-stored value), the terminal can perform neighboring based on the gap.区Measurement. Specifically, the terminal interrupts data transmission and reception with cell 1 in the gap, detects the synchronization signal of cell 2, uses the synchronization signal of cell 2 to establish synchronization with cell 2, and performs related measurements through the reference signal sent by cell 2 to complete Measurement on cell 2. If the measurement result of the cell 2 indicates that the signal strength of the cell 2 is greater than the preset value, the terminal switches to the cell 2 and resides in the cell 2.

Among them, the gap can be pre-configured or configured by the base station. For example, when a terminal accesses cell 1, cell 1 allocates a gap to the terminal so that the terminal can perform neighbor cell measurement in the gap. Fig. 2 shows a schematic diagram of an example of gap provided in an embodiment of the present application. The gap includes: measurement gap length (MGL), measurement gap repetition period (MGRP), and measurement offset (gapOffset) used to configure the starting position of the gap. The terminal can determine the system frame number (SFN) and subframe (subframe) corresponding to the start position of the gap according to these three parameters. Specifically, the system frame number (SFN) and subframe (subframe) corresponding to the start position of the gap meet the following conditions:

SFN mod T=FLOOR(gap Offset/10);

subframe=gap Offset mod 10;

T=MGRP/10;

Among them, FLOOR (gap Offset/10) is used to indicate that the value of gap Offset/10 is rounded down. gap Offset mod10 is used to instruct gap Offset to take the remainder of 10. Exemplarily, the maximum MGL can be 6ms.

In the above-mentioned neighbor cell measurement mechanism 1, the terminal interrupts the reception and transmission of data between the terminal and the serving cell in the gap, which will have a greater impact on the throughput. Therefore, the industry has proposed a neighboring cell measurement mechanism 2.

Measurement mechanism 2: Neighbor cell measurement based on no GAP, that is, measurement not based on gap. In other words, the terminal does not need to interrupt data transmission and reception with the serving cell in the GAP, and can also perform neighbor cell measurement. Therefore, for the serving cell, there is no need to allocate gaps for the terminal, saving transmission resources.

For example, for a terminal in the RRC_IDLE state or RRC_INACTIVE state, since the terminal is in an idle state most of the time and does not need to send and receive data on the serving cell, these idle times can be used for neighbor cell measurement, so the serving cell may not need to allocate gaps for the terminal.

For another example, in LTE, the terminal can support many different frequency/frequency band combinations, that is, the terminal has multiple radio frequency channels, so the terminal supports different frequencies/frequency bands on different radio frequency channels. When there is no need to configure the gap, the terminal can also directly perform neighbor cell measurement without affecting the terminal serving cell, so there is no need to interrupt the data transmission of the serving cell.

Assuming that the terminal supports frequency 1 and frequency 2, take the above scenario 2 as an example. The user-carried terminal is within the range of cell 1, and the terminal resides in cell 1. If the signal strength of cell 1 is less than the preset value, the terminal can send and receive data based on frequency 1 and cell 1, and measure cell 2 based on frequency 2. If the measurement result of the cell 2 indicates that the signal strength of the cell 2 is greater than the preset value, the terminal switches to the cell 2 and resides in the cell 2.

The terminal can decide whether to use a gap-based measurement method or a non-gap-based measurement method according to whether it has the no gap capability. If the terminal has multiple sets of radio frequency channels that can support neighbor cell measurement while receiving and sending signals on the serving cell, the terminal supports no gap neighbor cell measurement. Otherwise, the terminal needs to adopt a gap-based measurement method.

Taking the neighbor cell measurement as an example, the measurement of the primary cell (serving cell) can also be the measurement based on gap and the measurement based on no gap. Among them, the measurement of the primary cell may include, for example, the measurement of different frequency points of the primary cell and so on.

It should be noted that, currently, there is no solution for a terminal to report its no gap capability. Therefore, the following situations may exist. For example, if the terminal currently resides in cell 1, and cell 1 does not know whether the terminal supports no gap capability, it will configure gap for the terminal. If the terminal supports no gap capability, there is no need to configure gap, which will result in waste of transmission resources. For another example, the user carries the terminal from area 2 to area 1, and the terminal switches from cell 1 corresponding to area 1 to cell 2 corresponding to area 2. Cell 2 does not know whether the terminal supports the no gap capability, and will also configure gaps for the terminal, resulting in a waste of transmission resources.

Based on this, the embodiment of the present application provides a communication method, which provides a way for the terminal to report its own no gap capability. Among them, the terminal can indicate that the network equipment terminal has no gap capability through terminal capability signaling, cell handover request, or RRC reconfiguration complete message. Then the network device can determine that there is no need to configure the gap for the terminal based on the no gap capability reported by the terminal, saving transmission resources.

The communication method provided in the embodiments of the present application may be applicable to various scenarios, for example, a cell handover scenario, a random access scenario, and so on. In these scenarios, the terminal can report the no gap capability to the network device through the communication method provided in the embodiment of this application. Taking the random access scenario as an example, when the terminal accesses the serving cell, it can report the no gap capability to the serving cell. Taking the cell handover scenario as an example, when the terminal is handed over from the serving cell to the target cell, it can report the no gap capability to the serving cell or the target cell.

Refer to FIG. 3, which is a schematic diagram of a communication system provided by an embodiment of this application. As shown in Figure 3, the communication system includes: a terminal, a source base station, and a target base station. The terminal is currently connected to the source base station. When the terminal is handed over from the source base station to the target base station, it can report the no gap capability of the terminal to the source base station or the target base station.

Among them, the source base station is a base station under the first communication system, and the target base station is a base station under the second communication system. The first communication system is an LTE system, an NR system such as an EPC system or a 5G system, and the second communication system is an LTE system. System, NR system such as EPC system or 5G system, etc.

Example 1

The terminal indicates to the network equipment that the terminal has no gap capability through terminal capability signaling (UE capability information). The scenario in which the terminal reports terminal capability signaling to the network device may include: when the network device needs UE wireless access capability information, it sends a UE capability enquiry message (UE capability enquiry) to the UE in the RRC_connected state, and then the terminal Report terminal capability signaling. Or, when the terminal is currently in the RRC_idle state and switched to the RRC_connected state, it can actively or passively report the terminal capability signaling to the network device. It should be understood that the terminal capability signaling includes a RAT type, a list of supported frequency band combinations, and so on.

Refer to FIG. 4, which is a schematic flowchart of a communication method provided by an embodiment of this application. This method can be applied to the communication system shown in FIG. 3 or a similar communication system. As shown in Figure 4, the process of the method includes:

401. The terminal sends an RRC connection request (RRC connection request) to a network device.

It is understandable that before 401, the terminal is in the idle state. If the terminal needs to switch from the idle state to the connected state, 401 can be executed.

402. The terminal receives an RRC reconnection configuration (RRC connection setup) sent by the network device.

It is understandable that the RRC reconnection configuration may include the configuration of the terminal to reconnect to the network device, such as time-frequency resources.

403: The terminal switches from the idle state to the connected state.

404. The terminal sends an RRC reconnection configuration complete message (RRC connection setup complete) to the network device. The RRC reconnection configuration complete message is used to instruct the terminal to complete the RRC reconnection configuration.

405. The terminal receives a UE capability enquiry message (UE capability enquiry) sent by the network device.

In this embodiment of the application, the network device can instruct the terminal to report whether the terminal has the no gap capability through the UE capability query message. For example, the UE capability query message may carry indication information for instructing the terminal to report whether it has the no gap capability.

406. The terminal sends terminal capability signaling (UE capability information) to the network device, where the terminal capability signaling is used for the terminal to support no gap capability.

Example 1: When the terminal has the no gap capability, the UE capability signaling can be used to instruct the network equipment terminal to have the no gap capability. Exemplarily, the terminal may indicate in a display manner. For example, the UE capability signaling may include indication information used to indicate that the terminal has the no gap capability. Alternatively, the terminal may indicate in an implicit way. For example, the UE capability signaling does not include gap configuration information. After receiving the UE capability signaling, the network device determines that the UE capability signaling does not include the gap configuration information. Possess no gap capability. In the case that the terminal does not have the no gap capability, the UE capability signaling can be used to indicate that the network equipment terminal does not have the no gap capability. For example, the terminal may indicate in an explicit manner. For example, the UE capability signaling may include indication information used to indicate that the terminal does not have the no gap capability.

Example 2: When the terminal has the no gap capability, the UE capability signaling can be used to indicate in a display manner that the base station terminal has the no gap capability. In the case that the terminal does not have the no gap capability, the UE capability signaling can be used to indicate in an explicit or implicit manner that the base station terminal does not have the no gap capability. For example, the UE capability signaling includes indication information for indicating that the terminal does not have the no gap capability, or when the UE capability signaling does not include gap configuration information, it indicates that the terminal does not have the no gap capability.

In other embodiments, the terminal may also instruct the network device to indicate to the target network device that the terminal has no gap capability through UE capability signaling. For example, the terminal instructs the source base station to indicate to the target base station that the terminal has no gap capability through UE capability signaling. Then during the cell handover (handover) process, the source base station can indicate to the target base station that the terminal has no gap capability.

Example 2

The terminal indicates that the network equipment terminal has no gap capability through a cell handover request or an RRC reconfiguration complete message (RRC reconfiguration complete message). Applicable application scenarios include, for example, a cell handover process (handover). Wherein, the cell handover request is a request sent by the terminal to the network device for requesting cell handover. The RRC reconfiguration complete message (RRC reconfiguration complete message) is used to confirm the successful completion of the RRC connection reconfiguration (The RRC reconfiguration complete message is used to confirm the successful completion of an RRC connection reconfiguration). For example, when the terminal connects to the target network device based on the RRC reconfiguration message (RRC reconfiguration message), the RRC reconfiguration complete message can be used to indicate that the target network device terminal has no gap capability.

Among them, the RRC reconfiguration complete message can be borne on SRB1 or SRB3 wirelessly; the logical channel used to carry the RRC reconfiguration complete message is a dedicated control channel (DCCH).

Refer to FIG. 5, which is a schematic flowchart of another communication method provided in an embodiment of this application. This method can be applied to the communication system shown in FIG. 3. As shown in Figure 5, the process of the method includes:

500, the source base station provides services for the terminal. That is, the terminal is currently connected to the source base station.

501: The source base station determines that the terminal has no gap capability.

Exemplarily, 501 can have multiple ways.

Manner 1: The terminal indicates that the source base station terminal has no gap capability through terminal capability signaling (UE capability information). Refer to the description of the embodiment shown in FIG. 4, which will not be repeated here.

Manner 2: The terminal indicates whether the source base station terminal has the no gap capability through the cell handover request.

Example 1: When the terminal has the no gap capability, the cell handover request can be used to indicate the base station terminal to have the no gap capability in an explicit or implicit manner. For example, the cell handover request carries indication information used to indicate that the terminal has no gap capability, or when the cell handover request does not include gap configuration information, it is determined that the terminal has no gap capability. In the case that the terminal does not have the no gap capability, a cell handover request can be used to indicate in a display manner that the base station terminal does not have the no gap capability. For example, the cell handover request includes indication information used to indicate that the terminal does not have the no gap capability.

Example 2: In the case that the terminal has the no gap capability, a cell handover request can be used to indicate in a display manner that the base station terminal has the no gap capability. In the case that the terminal does not have the no gap capability, the cell handover request can be used to indicate in an explicit or implicit manner that the base station terminal does not have the no gap capability. For example, the cell handover request includes indication information used to indicate that the terminal does not have the no gap capability, or when the cell handover request does not include gap configuration information, it indicates that the terminal does not have the no gap capability.

It should be noted that the above methods 1 and 2 are two examples for the terminal to report whether it has the no gap capability to the source base station, and other methods for reporting whether the terminal has the no gap capability are also feasible.

It should be noted that the above method 1 and method 2 can be used alone or in combination, and the embodiments of the present application are not limited. For example, after the terminal indicates that the source base station itself has no gap capability through UE capability signaling, there is no need to indicate to the source base station that the terminal has no gap capability through a cell handover request. For another example, after the terminal indicates that the source base station itself has the no gap capability through the UE capability signaling, it may also indicate to the source base station that the terminal has the no gap capability through a cell handover request.

In other embodiments, the UE capability signaling and/or the cell handover request may also be used to instruct the source base station to indicate to other base stations that the terminal has no gap capability. When the source base station determines that the terminal needs to switch from the source base station to the target base station, it can indicate that the target base station terminal has no gap capability. In simple terms, after the terminal reconnects to the source base station, it can instruct the source base station to inform other base stations that the terminal has no gap capability through UE capability signaling or a cell switching request. The source base station can identify that the terminal has no gap capability and needs to relay to other base stations. When the source base station determines that the terminal needs to switch from the source base station to the target base station, it automatically instructs the target base station terminal to have no gap capability.

502. The source base station sends a cell handover request (handover request) to the target base station, where the cell handover request is used to indicate that the terminal has a no gap capability.

Optionally, in 502, the source base station can be indicated in an explicit or implicit manner. For example, the cell handover request sent by the source base station to the target base station carries indication information (for example, 1 bit) for indicating that the terminal has no gap capability. For another example, when the cell handover request sent by the source base station to the target base station does not carry gap configuration information, it indicates that the terminal has the no gap capability.

It is understandable that the cell handover request in 502 may also carry identification information of the terminal.

503: The source base station receives a handover request acknowledgement (handover request acknowledge) sent by the target base station.

It should be understood that after the target base station receives the cell handover request sent by the source base station, if it agrees to the terminal access, it sends a handover request response to the source base station, and the handover request response is used to indicate that the target base station agrees to the terminal access.

504: The source base station sends an RRC reconfiguration message (RRC reconfiguration message) to the terminal.

Optionally, the target base station may indicate RRC reconfiguration information through a handover request response, so that the terminal can switch to the target cell based on the RRC reconfiguration information. Or, after the target base station sends the handover request response to the source base station, the RRC reconfiguration information is sent to the source base station. Alternatively, the target base station may also directly send the RRC reconfiguration information to the terminal.

Among them, the RRC reconfiguration message can be used to modify the RRC connection command, and can be transmitted for measurement configuration, mobility control, radio resource configuration (including RBs, MAC master configuration, and physical channel configuration). The RRC reconfiguration message can be wirelessly carried in SRB1 or SRB3. The logical channel carried by the RRC reconfiguration message is the DCCH.

505: The terminal switches from the source base station to the target base station.

It should be understood that after receiving the RRC reconfiguration information, the terminal switches to the target base station based on the RRC reconfiguration information.

506: The terminal sends an RRC reconfiguration complete message (RRC reconfiguration complete) to the target base station, where the RRC reconfiguration complete message is used to indicate that the terminal has a no gap capability.

It should be understood that after switching to the target base station, the terminal may send an RRC reconfiguration complete message to the target base station to instruct the terminal to complete the RRC reconfiguration.

In this embodiment of the application, the terminal may indicate that the target base station terminal has the no gap capability through the RRC reconfiguration complete message.

Example 1: When the terminal has the no gap capability, the RRC reconfiguration complete message can be used to indicate in an explicit or implicit manner that the target base station terminal has the no gap capability. For example, the RRC reconfiguration complete message carries indication information for indicating that the terminal has no gap capability, or when the RRC reconfiguration complete message does not include gap configuration information, it is determined that the terminal has no gap capability. In the case that the terminal does not have the no gap capability, the RRC reconfiguration complete message can be used to indicate in a display manner that the target base station terminal does not have the no gap capability. For example, the RRC reconfiguration complete message includes indication information used to indicate that the terminal does not have the no gap capability.

Example 2: In the case that the terminal has the no gap capability, the RRC reconfiguration complete message can be used to indicate in a display manner that the base station terminal has the no gap capability. In the case that the terminal does not have the no gap capability, the RRC reconfiguration completion message can be used to indicate in an explicit or implicit manner that the base station terminal does not have the no gap capability. For example, the RRC reconfiguration complete message includes indication information for indicating that the terminal does not have the no gap capability, or when the RRC reconfiguration complete message does not include gap configuration information, it indicates that the terminal does not have the no gap capability.

It should be noted that in the foregoing 401, the terminal indicates that the source base station has no gap capability through UE capability signaling or cell handover request, and can also instruct the source base station to indicate to other base stations that the terminal has no gap capability, the terminal may not need to pass the RRC The reconfiguration complete message indicates that the target base station terminal has no gap capability. Or, if the terminal in 401 does not indicate that the source base station has no gap capability, or does not indicate that the source base station has no gap capability to the target base station, the terminal can indicate that the target base station has no gap capability through the RRC reconfiguration complete message . Of course, if the terminal in the aforementioned 401 indicates that the source base station has no gap capability through UE capability signaling or cell switching request, and instructs the source base station to indicate to other base stations that the terminal has no gap capability, the terminal also sends the RRC reconfiguration complete message Indicates that the target base station terminal has no gap capability.

As mentioned earlier, the terminal supports at least two communication links, and different communication links support different frequencies or frequency bands (that is, the terminal supports multiple frequencies/frequency bands). The terminal can use one communication link to maintain communication with the serving cell and use another communication link to maintain communication with the serving cell. The communication link performs neighbor cell measurement, that is, a terminal with at least two communication links has no gap capability. Therefore, the terminal can also report the frequency/band combination with no gap capability.

Exemplarily, the terminal may report the frequency/frequency band combination that the terminal has no gap capability through the following way 1 or way 2.

Method 1: The terminal reports all frequency/band combinations that support no gap capability.

It is understandable that the terminal may send the fourth indication information to the network device, which is used to instruct the network device terminal to support all frequency/frequency band combinations of no gap capability. Wherein, the fourth indication information may be carried in terminal capability signaling, cell handover request, or RRC reconfiguration complete message.

Assume that the terminal supports five frequencies/bands f1-f5. Then any two or more combinations of these 5 frequencies/bands will enable the terminal to have the capability of no gap neighboring cell measurement. Therefore, the terminal can report these 5 frequencies/frequency bands or all combinations between these 5 frequencies/frequency bands to the receiving end (for example, the source base station or the target base station).

For example, when the receiving end is the source base station, the terminal can indicate to the source base station all frequency/frequency band combinations for which the terminal has no gap capability through UE capability signaling or a cell handover request. It is understandable that the source base station may also indicate to the target base station all frequencies/frequency combinations for which the terminal has no gap capability through the cell handover instruction sent to the target base station.

For another example, when the receiving end is the target base station, the terminal can indicate all frequency/frequency band combinations with no gap capability through the RRC reconfiguration complete message.

In method 1, the terminal reports all frequency/frequency band combinations with no gap capability to the receiving end. The receiving end, such as the source base station or the target base station, can be configured based on the frequency/frequency band combination reported by the terminal. Taking the source base station as an example, when the source base station determines that the terminal supports five frequencies/frequency bands f1-f5, it can communicate with the terminal through frequency f1, so that the terminal can perform neighbor cell measurement through a certain frequency/frequency band in f2-f5 to ensure Serving cell data is not interrupted.

Manner 2: The terminal reports to the network device (source base station or target base station) one or more frequency/frequency band combinations supported by the network device among all frequency/frequency band combinations that the terminal supports no gap capability.

It is understandable that the terminal may send the fourth indication information to the network device, which is used to indicate one or more frequency/frequency band combinations supported by the network device among all frequency/frequency band combinations in which the terminal supports the no gap capability. Wherein, the fourth indication information may be carried in terminal capability signaling, cell handover request, or RRC reconfiguration complete message.

It is understandable that the terminal supports a certain number of frequencies/frequency bands, and the network device can also support a certain number of frequencies/frequency bands. The frequencies/bands supported by the two can be the same in whole or in part. Taking the network device as the target base station as an example, it is assumed that the target base station supports a total of 6 frequencies f3-f8, and the terminal supports five frequencies f1-f5. The terminal can indicate to the target base station that the terminal has a no gap neighbor cell measurement capability on any two frequency/frequency combination of f3-f5 among the 6 frequencies supported by the target base station. That is to say, in method 2, the terminal can only report one or more frequency combinations for which the terminal has no gap capability among all the frequency/frequency band combinations supported by the network device.

For example, when the network device is the source base station, the terminal can indicate to the source base station one or more frequency combinations with no gap capability among all frequency/frequency band combinations supported by the source base station through UE capability signaling or cell switching request. It is understandable that the source base station may indicate to the target base station one or more frequency combinations that indicate that the terminal has no gap capability at the target base station through the cell handover request sent to the target base station.

For another example, when the network device is the target base station, the terminal can indicate one or more frequency combinations for which the terminal has no gap capability among all the frequency/frequency band combinations supported by the target base station through the RRC reconfiguration complete message.

507: The target base station provides services for the terminal.

It is understandable that the above process of 501-506 realizes the terminal handover from the source base station to the target base station, and then the target base station provides services for the terminal.
