Description

Communication method and communication device

The present application claims priority of chinese patent application with application number 201911066738.7, entitled "a method and communication apparatus for NR reporting no gap capability" filed in 2019, 11/04, which is incorporated herein by reference in its entirety.

Technical Field

The present application relates to the field of communications technologies, and in particular, to a communication method and a communication apparatus.

Background

In the prior art, a terminal implements processes of cell access, cell handover, cell reselection, and the like through cell measurement. One way of measurement is in the gap (gap). For example, the terminal may interrupt data transmission and reception with the serving cell within the gap to perform the neighbor cell measurement. However, the terminal interrupts data transmission and reception with the serving cell within the gap, which greatly affects throughput. Therefore, it is proposed in LTE that a terminal can support a combination of different frequencies, i.e. the terminal has multiple radio frequency paths, and different frequencies are supported in different radio frequency paths. The terminal does not need to interrupt data receiving and sending with the service cell, and can also carry out neighbor cell measurement through other radio frequency channels, thereby not influencing the service cell. Therefore, the network side does not need to configure gaps (gap) for such terminals, or such terminals have no gap (no gap) capability.

At present, no relevant scheme that a terminal reports the capability of no gap exists.

Disclosure of Invention

The application provides a communication method and a communication device, which are used for providing a mode for reporting no gap capability by a terminal.

In a first aspect, a method of communication is provided, which may be implemented by a communication device. For example, the communication device may be a terminal device. When the communication device determines that the communication device has the gapless no GAP capability, the communication device may indicate, through a terminal capability signaling, a cell handover request, or an RRC reconfiguration complete message, that the network device has the no GAP capability.

Therefore, the embodiment of the present application provides a way for the terminal device to report the no GAP capability, so that the network device performs configuration based on the no GAP capability of the terminal device. For example, when the network device determines that the terminal apparatus has no GAP capability, it may not be necessary to configure a GAP for the terminal apparatus, thereby saving transmission resources.

The mode of reporting the no GAP capability by the terminal may include at least one of the following modes.

In the method 1, the communication device indicates, through the terminal capability signaling, that the network device communication device has the no GAP capability. For example, the communication apparatus sends terminal capability signaling to the network device, where the terminal capability signaling is used to instruct the network device to indicate to a target network device that the communication apparatus has no GAP capability.

For example, the terminal is in an idle state, and after the terminal is reconnected to the serving cell, the terminal capability signaling sent to the serving cell may be actively or passively, that is, the no GAP capability is reported through the terminal capability signaling, so that the serving cell is 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, it is not necessary to configure a GAP for the terminal device, and transmission resources are saved.

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

Mode 2, the communication device indicates to the network equipment through a cell switch request that the communication device is no GAP capable. For example, the communication apparatus sends a cell handover request to the network device, where the cell handover request is used to instruct the network device to indicate to a target network device that the communication apparatus is provided with no GAP capability.

For example, when the terminal determines that it needs to switch from the serving cell to the target cell, it may implement cell switching through a cell switching request, and report the no GAP capability to the serving cell, so that the serving cell is 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, it is not necessary to configure a GAP for the terminal device, and transmission resources are saved.

In the method 2, the cell handover request may indicate that the terminal has the no GAP capability in a display or implicit manner. For example, the configuration information (i.e. implicit indication) of the GAP is not included in the cell handover command; for another example, the cell handover request carries second indication information, where the second indication information is used to indicate that the communication device has no GAP capability (i.e. explicit indication).

Mode 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 apparatus is handed over from the network device to a target network device, an RRC reconfiguration complete message is sent to the target network device, where the RRC reconfiguration complete message is used to indicate that the communication apparatus has a no GAP capability.

For example, after the terminal is switched from the serving cell to the target cell, the terminal may instruct the network device terminal to complete cell switching through the RRC reconfiguration complete message, and report the no GAP capability to the target cell, so that the target cell performs configuration 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, it is not necessary to configure a GAP for the terminal device, and transmission resources are saved.

In the method 3, the RRC reconfiguration complete message may indicate that the terminal has the no GAP capability in a display or implicit manner. For example, the RRC reconfiguration complete message does not include configuration information (i.e., implicit indication) of the GAP; and/or, third indication information is carried in the RRC reconfiguration complete message, where the third indication information is used to indicate that the communication apparatus has a no GAP capability (i.e., an explicit indication).

In a possible design, the communication apparatus may further send, to the network device, fourth indication information, where the fourth indication information is used to indicate that the communication apparatus supports one or more frequency combinations of No GAP capabilities, where the one or more frequency combinations are all frequency combinations that the terminal supports No GAP capabilities, or one or more frequency combinations that the network device supports among all frequency combinations.

For example, after the terminal reports the frequency combination (for example, frequency 1 and frequency 2) of the capability of the terminal supporting the no GAP to the network device, the network device may perform configuration based on the frequency combination. For example, the network device may configure the terminal to use frequency 1 for data transmission with the network device, and configure the terminal to use frequency 2 for neighbor measurement. Therefore, the network equipment does not need to allocate the gap for the terminal, and transmission resources are saved.

In one possible design, before the communication apparatus indicates, through terminal capability signaling, a cell handover request, or an RRC reconfiguration complete message, that the communication apparatus has no GAP capability, the communication apparatus may further receive an inquiry request sent by the network apparatus, where the inquiry request is used to request to inquire the no GAP capability of the communication apparatus.

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

In this embodiment, the network device is a network device in a first communication system, and the target network device is a network device in a second communication system, where the first communication system is an LTE system, an EPC system, or a 5G system, and the second communication system is an LTE system, an EPC system, or a 5G system.

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

In a 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, wherein the first message is used for indicating that a terminal has no GAP capability, and the first message comprises terminal capability signaling, a cell switching request or an RRC reconfiguration completion message; and performing resource configuration based on the first message.

Therefore, the embodiment of the application provides a way for the terminal device to report the no GAP capability, so that the network device makes a decision based on the no GAP capability of the terminal device. For example, when the network device determines that the terminal apparatus has no GAP capability, it may not be necessary to allocate a GAP to the terminal apparatus, thereby saving transmission resources.

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

Wherein, the terminal capability signaling does not include configuration information of GAP; and/or carrying first indication information in the terminal capability signaling, wherein the first indication information is used for indicating that the terminal has no GAP capability.

Example 2, the first message is a cell handover request, that is, the communication device receives a cell handover request from the terminal or a communication device to which the terminal is currently accessing, where the cell handover request is used to instruct the communication device to indicate to a target communication device that the terminal is provided with no GAP capability.

Wherein the cell handover request does not include configuration information of a GAP; and/or the cell switching request carries second indication information, and the second indication information is used for indicating that the terminal has no GAP capability.

Example 3, the first message is an RRC reconfiguration complete message, that is, the communication apparatus receives an RRC reconfiguration complete message from the terminal, where the RRC reconfiguration complete message is used to indicate that the terminal has a no GAP capability.

Wherein, the RRC reconfiguration complete message does not contain configuration information of GAP; and/or the RRC reconfiguration complete message carries third indication information, wherein the third indication information is used for indicating that the terminal has no GAP capability.

In one possible design, the communication apparatus may further 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 capabilities, where the one or more frequency combinations are all frequency combinations of which the terminal supports No GAP capabilities, or one or more frequency combinations supported by the network device in all frequency combinations.

For example, after the terminal reports the frequency combination (for example, frequency 1 and frequency 2) of the capability of the terminal supporting the no GAP to the network device, the network device may perform configuration based on the frequency combination. For example, the network device may configure the terminal to use frequency 1 for data transmission with the network device, and configure the terminal to use frequency 2 for neighbor cell measurement. Therefore, the network equipment does not need to allocate the gap for the terminal, and transmission resources are saved.

In one possible design, the communication device may further send a query request for requesting a query for no GAP capability of the terminal before receiving the first message.

In a third aspect, there is also provided a communication device comprising means for performing the method of the first aspect or any one of the possible designs of the first aspect; these modules/units may be implemented by hardware, or by hardware executing corresponding software.

Such as Personal Communication Service (PCS) phones, cordless phones, Session Initiation Protocol (SIP) phones, Wireless Local Loop (WLL) stations, Personal Digital Assistants (PDAs), and the like. Also included are constrained devices, such as devices that consume less power, or devices that have limited storage capabilities, or devices that have limited computing capabilities, etc. Examples of information sensing devices include bar codes, Radio Frequency Identification (RFID), sensors, Global Positioning Systems (GPS), laser scanners, and so forth.

By way of example and not limitation, in the embodiments of the present application, the terminal may also be a wearable device. Wearable equipment also can be called as wearing formula smart machine or intelligent wearing formula equipment etc. is the general term of using wearing formula technique to carry out intelligent design, develop the equipment that can dress to daily wearing, like glasses, gloves, wrist-watch, bracelet, dress and shoes etc.. A wearable device is a portable device that is worn directly on the body or integrated into the clothing or accessories of the user. The wearable device is not only a hardware device, but also realizes powerful functions through software support, data interaction and cloud interaction. The generalized wearable smart device has full functions and large size, and can realize complete or partial functions without depending on a smart phone, for example: smart watches or smart glasses and the like, and only focus on a certain type of application functions, and need to be used in cooperation with other devices such as smart phones, such as various smart bracelets, smart helmets, smart jewelry and the like for monitoring physical signs.

While the various terminals described above, if located on a vehicle (e.g., placed in or mounted in a vehicle), may be considered to be vehicle-mounted terminals, also referred to as on-board units (OBUs), for example.

In this embodiment, the terminal may further include a relay (relay). Or, it is to be understood that all that can communicate data with the base station can be considered a terminal.

In the embodiment of the present application, the apparatus for implementing the function of the terminal may be the terminal, or may be an apparatus capable of supporting the terminal to implement the function, such as a chip system, and the apparatus may be installed in the terminal. In the embodiment of the present application, the chip system may be composed of a chip, and may also include a chip and other discrete devices. In the technical solution provided in the embodiment of the present application, a device for implementing a function of a terminal is taken as an example, and the technical solution provided in the embodiment of the present application is described.

3) The resources, which may also be referred to as transmission resources, include any one or a combination of multiple time domain resources, frequency domain resources, time frequency resources, or spatial domain resources.

4) The time unit, the time domain resource, includes one or more time units, and the time unit may be a radio frame, a subframe, a slot, a symbol, etc. One radio frame may include a plurality of subframes, one subframe may include one or more slots (slots), and one slot may include at least one symbol (symbol). Alternatively, one radio frame may include a plurality of slots, and one slot may include at least one symbol.

5) A gap (gap) comprising one or more time units. The gap (gap) may be pre-configured or dynamically configured on the network side. In the embodiment of the present application, the gapless (no gap) capability of the terminal may be that the terminal does not measure based on the gap, and thus the gap does not need to be configured. Wherein, 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, an RRC INACTIVE state (RRC _ INACTIVE) is introduced, that is, three states are supported in NR, an RRC IDLE state (RRC _ IDLE), an RRC INACTIVE state (RRC _ INACTIVE), and an RRC CONNECTED state (RRC _ CONNECTED), as shown in fig. 1. Wherein different RRC states can be switched between. For example, the UE may switch to the RRC _ CONNECTED state by an established (IDLE) connection mechanism while in the RRC _ IDLE state, and then fall back to the RRC _ IDLE state by a released (Release) connection mechanism. The UE is in RRC _ CONNECTED state, can switch to RRC _ INACTIVE by a delayed Release (Release with Suspend) connection mechanism, and then fall back to RRC _ CONNECTED state by a Resume (Resume) connection mechanism. When the UE is in the RRC _ INACTIVE state, the UE can be switched to the RRC _ IDLE state through a Release connection mechanism.

7) The mobility management mechanism of the terminal obtains continuous service of the wireless network by switching or reselecting the cells with different coverage areas. The cell handover or reselection scenario includes multiple scenarios, for example, scenario 1, where after the terminal accesses the current serving cell, the location of the terminal moves, for example, when the terminal is farther from the current serving cell, the terminal may need to perform cell handover or cell reselection. In scenario 2, when the service quality of the cell currently providing the service for 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 a better signal. Here, the current serving cell is a cell currently providing a service for the terminal, and the neighboring cell may be understood as a cell except for the serving cell, for which the terminal can search for a signal in the serving cell.

For example, the terminal has no RRC link with the current serving cell in the RRC _ IDLE state and the RRC _ INACTIVE state. When the signal quality of the serving cell where the terminal resides is lower than a certain threshold, neighbor cell measurement may be performed to measure the signal quality of the neighbor cell, and if the signal quality satisfies a condition, the terminal is switched to the neighbor cell and resides 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, an RRC connection exists between the terminal and the current serving cell. The current serving cell can configure the terminal to perform neighbor cell measurement through RRC signaling. And the terminal reports the measurement result of the adjacent cell to the serving cell, and the serving cell switches the terminal to the 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 switching (Handover) process.

It is understood that the above-mentioned cell reselection or cell handover process is performed based on the measurement result of the neighboring cell.

8) And (3) measuring the neighbor cell, wherein the terminal residing in the current serving cell can measure the relevant information (such as signal quality) of the neighbor cell so as to be used as a basis for cell switching or cell re-establishment. The currently supported neighbor cell measurement mechanisms include the following two mechanisms. Measurement mechanism 1: based on the measurement of the gap (gap). Within the gap, the terminal interrupts the reception and transmission of data with the serving cell, and performs neighbor cell measurement.

Taking the scenario 2 as an example, the user carries the terminal within the range of the cell 1, the terminal resides in the cell 1, and the terminal may perform the neighbor cell measurement based on the gap, assuming that the signal strength of the cell 1 is smaller than a preset value (may be a pre-stored value). Specifically, the terminal interrupts data transmission and reception with the cell 1 within the gap, detects the synchronization signal of the cell 2, establishes synchronization with the synchronization signal of the cell 2 and the cell 2, and performs correlation measurement through the reference signal transmitted by the cell 2, thereby completing measurement of the cell 2. If the signal strength of the cell 2 represented by the measurement result of the cell 2 is greater than the preset value, the terminal is switched to the cell 2 and resides in the cell 2.

Wherein the gap may be preconfigured or configured by the base station. For example, when the terminal accesses the cell 1, the cell 1 allocates a gap to the terminal, so that the terminal performs neighbor cell measurement in the gap. Fig. 2 is a schematic diagram illustrating an example of a gap provided in an embodiment of the present application. The gap comprises: a measurement slot length (MGL), a measurement slot repetition period (MGRP), and a measurement offset (gapOffset) for configuring a start position of a gap. The terminal may determine a System Frame Number (SFN) and a subframe (subframe) corresponding to the start position of the gap according to the 3 parameters. Specifically, the System Frame Number (SFN) and the subframe (subframe) corresponding to the start position of the gap satisfy the following condition:

SFN mod T＝FLOOR(gap Offset/10)；

subframe＝gap Offset mod 10；

T＝MGRP/10；

wherein, FLOOR (gap Offset/10) is used to indicate that the value of gap Offset/10 is rounded down. gap Offset mod 10 is used to indicate that gap Offset takes the remainder for 10. Exemplarily, the MGL may be 6ms maximum.

In the foregoing neighboring cell measurement mechanism 1, the terminal interrupts reception and transmission of data between the terminal and the serving cell within the gap, which may greatly affect throughput. Therefore, the neighboring cell measurement mechanism 2 is proposed in the industry.

Measurement mechanism 2: neighbor measurements based on gapless (no GAP), i.e. measurements not based on GAP. That is, the terminal may perform the neighbor cell measurement without interrupting data transmission and reception with the serving cell in the GAP. Therefore, for the serving cell, the gap does not need to be allocated to the terminal, and transmission resources are saved.

For example, for a terminal in RRC _ IDLE state or RRC _ INACTIVE state, since the terminal is mostly in IDLE state and does not need to transmit and receive data on the serving cell, these IDLE times can be used for neighbor cell measurement, and therefore the serving cell may not need to allocate gap to the terminal.

For another example, in LTE, a terminal may support many different frequency/frequency band combinations, i.e., the terminal has multiple radio frequency paths, so the terminal supports different frequencies/frequency bands on different radio frequency paths. Under the condition of not needing to configure gap, the terminal can also directly carry out neighbor cell measurement, and the influence on a terminal service cell is not caused, so that the data transmission of the service cell is not needed to be interrupted.

Assume that the terminal supports frequency 1 and frequency 2, taking scenario 2 above as an example. A user carries a terminal in the range of a cell 1, the terminal resides in the cell 1, if the signal intensity of the cell 1 is smaller than a preset value, the terminal can receive and transmit data with the cell 1 based on a frequency 1, and a cell 2 is measured based on a frequency 2. And if the measurement result of the cell 2 indicates that the signal intensity of the cell 2 is greater than the preset value, the terminal is switched to the cell 2 and resides in the cell 2.

The terminal may determine to adopt a measurement mode based on gap or a measurement mode not based on gap according to whether the terminal has no gap capability. If the terminal has multiple sets of radio frequency channels, the terminal can support neighbor cell measurement while receiving and sending signals on the serving cell, and then the terminal supports no gap neighbor cell measurement. Otherwise, the terminal needs to adopt a gap-based measurement mode.

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

It should be noted that, at present, there is no scheme for reporting no gap capability by a terminal. Therefore, there may be the following cases. For example, when the terminal currently resides in the cell 1, the cell 1 does not know whether the terminal supports no gap capability, and then configures gap for the terminal, and if the terminal supports no gap capability, the terminal does not need to configure gap, which results in waste of transmission resources. For another example, the user carries the terminal to the area 2 moved from the area 1, and the terminal is switched from the cell 1 corresponding to the area 1 to the cell 2 corresponding to the area 2. Cell 2 does not know whether the terminal supports no gap capability, and will also configure gap for the terminal, resulting in wasted transmission resources.

Based on this, the embodiment of the present application provides a communication method, which provides a way for a terminal to report its no gap capability. The terminal may indicate that the network device terminal has a no gap capability through a terminal capability signaling, a cell handover request, or an RRC reconfiguration complete message. Then, the network device may determine that it is not necessary to configure a gap for the terminal based on the no gap capability reported by the terminal, thereby saving transmission resources.

The communication method provided by the embodiment of the application can be applied to various scenes, such as a cell switching scene, a random access scene and the like. In these scenarios, the terminal may report the no gap capability to the network device through the communication method provided in the embodiment of the present application. Taking a random access scenario as an example, when the terminal accesses a serving cell, the no gap capability may be reported to the serving cell. Taking a cell switching scenario as an example, in the process of switching the terminal from the serving cell to the target cell, the terminal may report the no gap capability to the serving cell or the target cell.

Referring to fig. 3, a schematic diagram of a communication system according to an embodiment of the present application is shown. As shown in fig. 3, the communication system includes: a terminal, a source base station and a target base station. The terminal is currently accessed to the source base station. In the process of switching the terminal from the source base station to the target base station, the no gap capability of the terminal may be reported to the source base station or the target base station.

The source base station is a base station in a first communication system, and the target base station is a base station in a second communication system, where the first communication system is an LTE system or an NR system such as an EPC system or a 5G system, and the second communication system is an LTE system or an NR system such as an EPC system or a 5G system.

Example 1

The terminal indicates, through a terminal capability signaling (UE capability information), that the network device has a no gap capability. The scenario that the terminal reports the terminal capability signaling to the network device may include: when the network equipment needs the UE wireless access capability information, a UE capability query message (UE capability query) is sent to the UE in the RRC _ connected state, and then the terminal reports a terminal capability signaling. Or, when the terminal is currently in the RRC _ idle state and is switched to the RRC _ connected state, the terminal capability signaling may be actively or passively reported to the network device. It should be understood that the RAT type, the supported band combination list, and the like are included in the terminal capability signaling.

Referring to fig. 4, a schematic flowchart of a communication method according to an embodiment of the present application is shown. The method may be applied in the communication system shown in fig. 3 or a similar communication system. As shown in fig. 4, the process of the method includes:

401, the terminal sends an RRC reconnection request (RRC connection request) to the network device.

It is to be understood that before 401, the terminal is in an idle state, and if the terminal needs to switch from the idle state to a connected state, 401 may be performed.

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

It is understood that the RRC reconnection configuration may include a configuration in which the terminal re-accesses 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 completion message is used for indicating the terminal to complete RRC reconnection configuration.

405, the terminal receives a UE capability query message (UE capability inquiry) sent by the network device.

In the embodiment of the application, the network device may indicate, through the UE capability query message, whether the terminal reporting terminal has a no gap capability. For example, the UE capability query message may carry indication information for indicating whether the terminal reports itself with a no gap capability.

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

Example 1, in the case that the terminal has the no gap capability, the network device may be indicated by the UE capability signaling that the terminal has the no gap capability. For example, the terminal may indicate through a display manner, for example, the UE capability signaling may include indication information for indicating that the terminal is provided with no gap capability. Or, the terminal may indicate in an implicit manner, for example, that the UE capability signaling does not include gap configuration information, and when it is determined that the UE capability signaling does not include gap configuration information after the network device receives the UE capability signaling, it is determined that the terminal has no gap capability. Under the condition that the terminal does not have the no gap capability, the network equipment terminal can be indicated to have no gap capability through the UE capability signaling. For example, the terminal may indicate in an explicit manner, for example, indication information for indicating that the terminal is not capable of no gap may be included in the UE capability signaling.

Example 2, in the case that the terminal has no gap capability, the base station terminal may be indicated to have no gap capability through UE capability signaling in a display manner. Under the condition that the terminal does not have the no gap capability, the base station terminal can be indicated to have no gap capability in a display or recessive mode through UE capability signaling. For example, the UE capability signaling includes indication information for indicating that the terminal does not have a no-gap capability, or indicates that the terminal does not have a no-gap capability when the UE capability signaling does not include gap configuration information.

In other embodiments, the terminal may further indicate, by the UE capability signaling, the network device to indicate to the target network device that the terminal is provided with no gap capability. For example, the terminal instructs the source base station to indicate the terminal has no gap capability to the target base station through UE capability signaling. Then in the cell handover (handover) procedure, the source base station may indicate to the target base station that the terminal has no gap capability.

Example 2

The terminal indicates the network device terminal to have no gap capability through a cell switching request or an RRC reconfiguration complete message (RRC reconfiguration complete message). Suitable application scenarios include, for example, a cell handover procedure (handover). The cell switching request is a request which is sent by the terminal to the network equipment and is used for requesting cell switching. The RRC reconfiguration complete message (RRC reconfiguration complete message) is used to confirm successful completion of RRC connection reconfiguration (The RRC reconfiguration complete message is used to configure The communication function of an RRC connection reconfiguration). For example, when the terminal connects to the target network device based on RRC reconfiguration message (RRC reconfiguration message), the terminal may indicate that the target network device has no gap capability through RRC reconfiguration message.

Wherein, the RRC reconfiguration message may be wirelessly carried in SRB1 or SRB 3; the logical channel for carrying the RRC reconfiguration message is a Dedicated Control Channel (DCCH).

Referring to fig. 5, a schematic flowchart of another communication method provided in the embodiment of the present application is shown. The method may be applied in the communication system shown in fig. 3. As shown in fig. 5, the flow of the method includes:

500, the source base station provides a service for the terminal. I.e. the terminal is currently accessing the source base station.

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

Illustratively, 501 may be in a variety of ways.

In the method 1, the terminal indicates that the source base station terminal has no gap capability through the terminal capability signaling (UE capability information). Referring to the description of the embodiment shown in fig. 4, the description is not repeated here.

In the mode 2, the terminal indicates whether the source base station terminal has no gap capability through the cell switching request.

Example 1, in the case that the terminal has the no gap capability, the base station terminal may be indicated to have the no gap capability in a display or implicit manner through the cell handover request. For example, when the cell handover request carries indication information for indicating that the terminal has a no gap capability, or when the cell handover request does not include gap configuration information, it is determined that the terminal has the no gap capability. And under the condition that the terminal does not have the no gap capability, the terminal can indicate that the base station terminal does not have the no gap capability through the cell switching request in a display mode. For example, the cell handover request includes indication information indicating that the terminal does not have a no gap capability.

Example 2, in the case that the terminal has no gap capability, the base station terminal may be indicated to have no gap capability through a cell handover request in a display manner. Under the condition that the terminal does not have the no gap capability, the terminal can indicate that the base station terminal does not have the no gap capability through the cell switching request in a display or recessive mode. For example, the cell handover request includes indication information indicating that the terminal does not have the no-gap capability, or when the cell handover request does not include the gap configuration information, the cell handover request indicates that the terminal does not have the no-gap capability.

It should be noted that, the above-mentioned modes 1 and 2 are two examples of reporting whether the terminal has the no-gap capability to the source base station, and other modes of reporting whether the terminal has the no-gap capability are also feasible.

Mode 1 and mode 2 may be used alone or in combination, and the present embodiment is not limited thereto. For example, after the terminal indicates that the source base station has the no-gap capability through the UE capability signaling, the terminal does not need to indicate that the terminal has the no-gap capability to the source base station through the cell handover request. For another example, after the terminal indicates that the source base station has the no gap capability through the UE capability signaling, the terminal may also indicate that the terminal has the no gap capability to the source base station through the 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 the other base stations that the terminal is no-gap capable. When the source base station determines that the terminal needs to be switched from the source base station to the target base station, the target base station may be indicated to have a no gap capability. In short, after the terminal is reconnected to the source base station, the source base station may be indicated by UE capability signaling or a cell handover request to inform other base stations that the terminal has no gap capability. The source base station may identify that the terminal is no gap capable and needs to refer to other base stations. And when the source base station determines that the terminal needs to be switched from the source base station to the target base station, automatically indicating that the target base station terminal has 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 no gap capability.

Optionally, in 502, the source base station may indicate in a display or implicit manner. For example, the cell handover request sent by the source base station to the target base station carries indication information (e.g., 1bit) 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, the terminal is indicated to have a no gap capability.

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

503, the source bs receives a handover request acknowledgement (handover request acknowledge) sent by the target bs.

It should be understood that, after receiving the cell handover request sent by the source base station, the target base station sends a handover request response to the source base station if the terminal access is granted, where the handover request response is used to indicate that the target base station grants the terminal access.

The source base station transmits RRC reconfiguration message (RRC reconfiguration message) to the terminal 504.

Optionally, the target base station may indicate the RRC reconfiguration information through the handover request response, so that the terminal is handed over to the target cell based on the RRC reconfiguration information. Or after the target base station sends the switching request response to the source base station, the target base station sends RRC reconfiguration information to the source base station. Alternatively, the target base station may directly transmit the RRC reconfiguration information to the terminal.

Among them, the RRC reconfiguration message may be used to modify the RRC connection command, and may transmit commands for measurement configuration, mobility control, radio resource configuration (including RBs, MAC main configuration, and physical channel configuration), and the like. The RRC reconfiguration message may be wirelessly carried in SRB1 or SRB 3. The logical channel carried by the RRC reconfiguration message is DCCH.

And 505, the terminal is switched 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 no gap capability.

It should be understood that, after the terminal is handed over to the target base station, an RRC reconfiguration complete message may be sent to the target base station to instruct the terminal to complete RRC reconfiguration.

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

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

Example 2, in the case that the terminal has the no gap capability, the base station terminal may be indicated to have the no gap capability in a display manner through an RRC reconfiguration complete message. Under the condition that the terminal does not have the no gap capability, the base station terminal can be indicated to have no gap capability in a display or recessive mode through the RRC reconfiguration completion message. 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 the gap configuration information, the RRC reconfiguration complete message indicates that the terminal does not have the no-gap capability.

It should be noted that, in the above 401, the terminal indicates, through the UE capability signaling or the cell handover request, that the source base station terminal has the no gap capability, and may also indicate, to the other base stations, that the terminal indicates that the terminal has the no gap capability, where the terminal may not need to indicate, through the RRC reconfiguration complete message, that the target base station terminal has the no gap capability. Or, in the above 401, when the terminal does not indicate that the source base station terminal has the no gap capability, or does not indicate that the source base station indicates that the target base station terminal has the no gap capability, the terminal may indicate that the target base station terminal has the no gap capability through the RRC reconfiguration complete message. Of course, in the above 401, under the condition that the terminal has indicated that the source base station terminal has the no gap capability through the UE capability signaling or the cell handover request, and indicates that the source base station indicates that the terminal has the no gap capability to other base stations, the terminal further indicates that the target base station terminal has the no gap capability through the RRC reconfiguration complete message.

As described above, the terminal supports at least two communication links, different communication links support different frequencies or frequency bands (i.e., the terminal supports multiple frequencies/frequency bands), and the terminal may use one communication link to maintain communication with the serving cell and perform neighbor cell measurement through the other communication link, that is, the terminal with at least two communication links has no gap capability. Therefore, the terminal can also report the frequency/frequency band combination with no gap capability.

For example, the terminal may report the frequency/frequency band combination with no gap capability through the following manner 1 or manner 2.

In the mode 1, the terminal reports all frequency/frequency band combinations supporting the no gap capability.

It is to be understood that the terminal may send fourth indication information to the network device, for indicating that the network device supports all frequency/frequency band combinations of no gap capability. The fourth indication information may be carried in a terminal capability signaling, a cell handover request, or an RRC reconfiguration complete message.

Assume that the terminal supports five frequencies/bands f1-f 5. Then any two or more combinations between these 5 frequencies/bands will enable the terminal to have the capability of no gap neighbor measurement. Therefore, the terminal may report the 5 frequencies/bands or all combinations between the 5 frequencies/bands to the receiving end (e.g., the source base station or the target base station).

For example, when the receiving end is the source base station, the terminal may 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 to be understood that the source base station may also indicate to the target base station all frequencies/frequency combinations for which the terminal is no gap capable, by means of a cell handover command sent to the target base station.

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

In the mode 1, the terminal reports all frequency/frequency band combinations with no gap capability to the receiving end. A receiving end, such as a source base station or a target base station, may 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, the source base station may communicate with the terminal through the frequency f1, so that the terminal may perform neighbor cell measurement through a certain frequency/frequency band of the frequencies f2-f5, so as to ensure that data of a serving cell is not interrupted.

In the method 2, the terminal reports one or more frequency/frequency band combinations supported by the network device among all frequency/frequency band combinations of which the terminal supports no gap capability to the network device (source base station or target base station).

It is to be understood that the terminal may send fourth indication information to the network device, where the fourth indication information indicates 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. The fourth indication information may be carried in a terminal capability signaling, a cell handover request, or an RRC reconfiguration complete message.

It is to be understood that the terminal supports a certain number of frequencies/bands, and the network device may also support a certain number of frequencies/bands. The frequencies/frequency bands supported by both may be wholly or partially identical. Taking the network device as the target base station as an example, assuming that the target base station supports 6 frequencies f3-f8, and the terminal supports five frequencies f1-f 5. The terminal may indicate, to the target base station, that the terminal has a neighbor measurement capability of no gap on any two frequency/frequency band combinations of f3-f5 in the 6 frequencies supported by the target base station. That is, in the method 2, the terminal may report only one or more frequency combinations that the terminal has no gap capability among all frequency/frequency band combinations supported by the network device.

For example, when the network device is a source base station, the terminal may indicate, to the source base station, one or more frequency combinations that the terminal has no gap capability among all frequency/frequency band combinations supported by the source base station through UE capability signaling or a cell handover request. It is to be understood that the source base station may indicate to the target base station one or more frequency combinations at the target base station indicating that the terminal is no gap capable by means of a cell handover request sent to the target base station.

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

And 507, the target base station provides service for the terminal.

It can be understood that the above-mentioned processes 501-506 implement the handover of the terminal from the source base station to the target base station, and then the target base station provides the service for the terminal.
