However, for illustrative purposes, the following description will describe a New Radio (NR) system, and NR terminology will be used in most of the following description, but these technologies are applicable to systems other than NR systems, such as 6th Generation (6G) communication systems.

[0022] FIG. 1 shows a schematic diagram of a wireless communication system applicable to the embodiments of the present application. The wireless communication system includes a terminal 11 and a network device 12. Here, the terminal 11 may be referred to as a terminal device or user equipment (UE), and may be a terminal-side device such as a mobile phone, a tablet personal computer, a laptop computer (also called a notebook computer), a personal digital assistant (PDA), a personal digital assistant, a netbook, an ultra-mobile personal computer (UMPC), a mobile internet device (MID), a wearable device, a vehicle-mounted equipment (VUE), a pedestrian-mounted equipment (PUE), etc. Wearable devices include smart watches, bracelets, earphones, glasses, etc. It should be noted that the specific type of the terminal 11 is not limited to the embodiments of the present application.

As long as the same technical effect can be achieved, the base station is not limited to a specific technical term. In the embodiments of the present application, only a base station in an NR system is taken as an example, but it should be noted that the specific type of the base station is not limited.

[0023] Hereinafter, the technical means provided in the embodiments of the present application will be described in detail with reference to the drawings through several embodiments and use cases thereof.

[0024] 2 shows a flowchart of a gap placement method 200 provided in an exemplary embodiment of the present application, which may be performed by a terminal, but is not limited to this, and may specifically be performed by hardware and / or software implemented in the terminal. In this embodiment, the method 200 may include at least the following steps S210 and S220.

[0025] In S210, the terminal transmits a first request to the network device.

[0026] Here, the first request is used to request the network device to configure or reconfigure at least one gap associated with a DC state. In this embodiment, "associated with a DC state" can be understood as requesting the network device to configure at least one gap for the DC state by the first request when the terminal is configured in the DC state, or requesting the network device to pre-configure a gap in the DC state by the first request when the terminal is not configured in the DC state (e.g., currently in a single-connection state). It should be noted that the network configures a gap for the terminal before the terminal is configured in dual-connection, and this configured gap can be used in the single-connection state.

[0027] It should be noted that the gap described in this embodiment may be a Multiple Subscriber Identity Module (Multi-SIM) gap or other gap. It can be understood that the terminal requests a network device to set a gap in order to allow the terminal to temporarily not perform a specific operation in the network during the gap period. For example, the terminal may not monitor the scheduling of the network during the gap period, or may not monitor the channel of the network in which it is located during the gap period. The specific purpose for the terminal to use the gap is not limited by this application. For example, the terminal requests a gap in network 1, and network 1 allows the terminal not to monitor the scheduling of the network during the gap period. The terminal can perform a measurement service in the network during the gap period, or transition to a network of another subscriber identity module to perform a service.

[0028] Note that this application does not limit the name of the gap, and for example, the gap may also be referred to as a gap, withdrawal time, withdrawal time length, withdrawal gap, suspend time, suspend time length, suspend gap, deactivation time, deactivation time length, deactivation gap, etc.

[0029] Optionally, if the first request is used to request multiple gaps, the multiple gaps may be gaps with different time information and different types, gaps with the same time information and different types, gaps with different time information and the same type, etc., and are not limited here.

[0030] In this embodiment, the network device that receives the first request may differ depending on whether the terminal is in a DC state. For example, when the terminal is in a DC state, the network device may include an MN and / or an SN. That is, when the terminal is in a DC state, the terminal may send the first request only to an MN to request the MN to configure or rearrange at least one gap, or may send the first request only to an SN to request the SN to configure or rearrange at least one gap, or may send the first request to an MN and an SN at different times or simultaneously to request the MN and the SN to configure or rearrange at least one gap, respectively.

[0031] It should be noted that when the terminal sends the first request only to the MN, the gap configuration information may be determined independently by the MN, or the MN may forward the first request or information related to the SN in the first request to the SN, and then the SN may determine the gap configuration information independently, or the MN and SN may negotiate to determine the gap configuration information.

[0032] Alternatively, when the terminal sends the first request only to the SN, the SN may determine the gap allocation information independently, or the SN may forward the first request or information related to the MN in the first request to the MN, and then the MN may determine the gap allocation information independently, or the MN and SN may negotiate to determine the gap allocation information.

[0033] Alternatively, when the terminal sends the first request to the MN and the SN, the first request may include information related to the MN and the SN at the same time, or may include only information related to the MN, or may include only information related to the SN, and the gap configuration information may be determined by the MN and the SN in consultation with each other or independently.

[0034] Further, for example, when the terminal is not placed in the DC state, the network device receiving the first request may include a first serving base station (not including an MN or an SN) that provides access service to the terminal, and the gap configuration information is determined by the first serving base station and a second serving base station, and the second serving base station includes at least one candidate SN. This can be understood as meaning that when the terminal is not placed in the DC state, gap configuration information in the DC state, such as MCG gap configuration information, SCG gap configuration information, etc., may be pre-configured by the first serving base station and / or the second serving base station.

[0035] Furthermore, if there is a candidate SN (i.e., a second serving base station) for the terminal, the candidate SN may be involved in the gap configuration procedure. For example, if no SN is configured for the terminal, but the current serving base station (i.e., the first serving base station) of the terminal attempts to configure candidate SN1 as the SN for the terminal, the first serving base station of the current terminal may transmit at least part of the information of the first request and / or at least part of the information of the gap configuration information determined by the MN to the candidate SN before transmitting gap configuration information to the terminal, so that the candidate SN1 may determine appropriate gap configuration information, for example, an SCG gap. In one implementation, when the terminal sends a first request to the network device, the network device may instruct the terminal whether or not the terminal is allowed to send the first request by a broadcast message or dedicated signaling.

[0036] It should be noted that the first request described in this application may be sent via Radio Resource Control (RRC), Medium Access Control-Control Element (MAC CE) or Uplink Control Information (UCI), and the subsequent Gap placement information may be sent via RRC, MAC CE or Downlink Control Information (DCI), and this application is not limited thereto.

[0037] In S220, the terminal receives gap arrangement information transmitted from the network device.

[0038] Here, the gap configuration information is used for the terminal to configure or reconfigure at least one of the gaps in a DC state.

[0039] In one implementation, after receiving gap arrangement information sent from the network device, the terminal may re-send a first request to the network device. In this way, if the gap arrangement information sent from the network device does not meet the gap needs of the terminal or the gap needs of the terminal have changed, the terminal may request the network device to adjust the gap arrangement by re-sending the first request so as to correspond to the gap needs of the terminal.

[0040] In this embodiment, flexible gap placement can be realized according to the DC state by requesting gap placement from the corresponding network equipment after fully considering whether the terminal is placed in the DC state or not; on the other hand, the terminal can directly request an MCG gap from the MN and directly request an SCG gap from the SN, which does not require consultation and information exchange between the MN and the SN, avoids problems such as the transmission of gap placement-related information between network interfaces, reduces gap request / placement delay and system signaling overhead, and effectively improves the communication performance of the terminal in the DC state (or architecture).

[0041] 3 shows a flowchart of a gap placement method 300 provided in an exemplary embodiment of the present application, which may be performed by a terminal, but is not limited to this, and may be specifically performed by hardware and / or software implemented in the terminal. In this embodiment, the method 300 may include at least the following steps S310, S320, and S330.

[0042] In S310, the terminal sends a first request to the network device.

[0043] Here, the first request is used to request the network device to configure or reconfigure at least one gap associated with a DC state.

[0044] It should be noted that the implementation procedure of S310 can be referred to the relevant description in the method embodiment 200. In addition, as one possible implementation form, the first request may include at least one of the following items (1)-(8):

[0045] (1) GAP identifier.

[0046] Here, the gap identifiers may be included in the first request explicitly or implicitly, for example, the gap identifiers may be implicitly indicated in descending order of gap duration. For example, if a terminal requests three gaps with durations of 80, 40, and 20, the identifiers of these three gaps are ordered by gap duration, and the order of appearance of the three gaps indicates the first, second, and third identifiers. If the terminal requests to use the first gap, it means that a gap with a duration of 80 will be used.

[0047] Furthermore, if the first request is used to request one gap arrangement, the first request does not need to include a gap identifier, and if the first request is used to request multiple gap arrangements, the first request may include a gap identifier to distinguish between multiple different gaps.

[0048] (2) Gap type.

[0049] Here, the gap type includes at least one of a gap for each terminal (per UE), a gap for each frequency range (per FR), an FR1 gap, an FR2 gap, a gap for each cell group (per CG), an MCG gap, an SCG gap, a periodic gap, a one-shot gap, a gap for each transmission direction (per direction gap), a gap for the uplink direction (UL), and a gap for the downlink direction (DL).

[0050] In this embodiment, some gap types may be configured in a manner such as protocol specification or network configuration, etc. For example, if the terminal requests per FR gap, the network device may implicitly recognize that the per FR gap type requested by the terminal includes a UL gap and a DL gap; for example, if the first request is sent in cell group A and the gap type is a one-shot gap, the network device may implicitly recognize that the requested gap type is the gap of cell group A.

[0051] In other embodiments, the gap type may be a gap for each carrier, a gap for each Bandwidth Part (BWP), a gap for each serving cell, or a gap of other granularity, and the present application is not limited thereto.

[0052] (3) Gap related time information.

[0053] Here, the relevant time information of the gap includes at least one of gap length, gap period, gap start time, gap end time, and gap scale factor. In this embodiment, different gaps may have the same or different time information, such as gap length, gap period, gap start time, gap end time, etc.

[0054] In one embodiment, the gap-related time information may further include a gap scale factor for dividing the at least one gap. For example, the terminal may send a first request to request allocation of at least one gap and indicate a scale factor of 1, and then the network configures the gap to the terminal. When the terminal operates in a single-connection state, no scale factor is used. When the terminal operates in a dual-connection state, the terminal determines that the MCG gap and the SCG gap are the first and second half gaps of the configured gap, respectively, according to the configured gap duration and scale factor.

[0055] It should be noted that the gap scale factor may be a specific number defined by a protocol or configured in a network, or an index value or number value of a certain mapping relationship, and is not limited thereto.

[0056] (4) First instruction information for indicating a request type of the first request, including at least one of adding a gap allocation, modifying a gap allocation, and releasing a gap allocation, wherein adding a gap allocation may be understood as allocating or newly increasing a gap, modifying a gap allocation may be understood as rearranging a gap, and releasing a gap allocation may be understood as deleting or canceling a gap.

[0057] (5) Second instruction information for requesting enabling or disabling of at least one gap.

[0058] For example, one bit of instruction information may instruct the terminal to perform an enable (which may be understood as requesting use, including using the allocated gap or using it immediately after allocation) or disable (which may be understood as not using, including not using it immediately after allocation or stopping use of the allocated gap) operation on the allocated gap.

[0059] Further, for example, the second indication information may be a number of bits indicating a gap identifier, that is, indicating the gap identifier corresponding to the gap to be enabled or disabled.

[0060] Further, for example, the second indication information may indicate a gap type, that is, the gap type corresponding to the gap to be enabled or disabled.

[0061] (6) Third instruction information for instructing the terminal to return to the network early during the gap period.

[0062] In one implementation, the third indication information is not only used to instruct the terminal to return to the network early during the gap period, but also to instruct the terminal to monitor the channel during the gap period, or the terminal to monitor network scheduling, or the terminal to request network scheduling, or to dynamically indicate the gap end time of the terminal, etc., and is not limited thereto.

[0063] (7) Fourth instruction information for instructing the terminal to request gap relocation during the gap period or to request gap switching during the gap period.

[0064] In one implementation, assuming that the gap currently used by the terminal is gap A, the terminal can use the fourth instruction information to indicate that gap A needs to be relocated during gap A, or to request switching from gap A to gap B.

[0065] Here, gap A or gap B may be a periodic gap or a one-shot gap.

[0066] (8) Fifth instruction information for instructing a DC-related operation mode of the terminal during a gap period.

[0067] Here, the operation mode may include an uplink power sharing mode, a DC state, a non-DC state, etc.

[0068] For example, the fifth indication information may indicate an uplink power sharing mode to be requested for configuration when the terminal is configured in a DC, and further, for example, the fifth indication information may indicate whether a gap requested for configuration in the first request when the terminal is not configured in a DC is applicable when the terminal is configured in a DC. Further, for example, the fifth indication information may be used to further indicate whether the terminal wants to be configured in a DC state.

[0069] Based on the above, in order to improve the efficiency and reliability of gap placement, as one possible implementation form in this embodiment, when the network equipment includes an MN and at least one of the following items (1)-(8) is satisfied, the terminal can send a first request to the MN.

[0070] The first request is used to request per UE gap configuration or reconfiguration.

[0071] Here, per UE gap may be understood to mean that the gap type requested in the first request is at least a per UE type gap, and as can be understood, per UE gap may further be a periodic gap type, a one-shot gap type, or other gap type, and as long as they do not contradict each other, this application does not limit this, and the same applies below, and detailed explanations will be omitted.

[0072] (2) The first request is used to request placement or rearrangement of an FR1 gap.

[0073] In one implementation, when an intra-FR1 DC is configured in a terminal and the first request is used to request configuration or rearrangement of an FR1 gap, the terminal may send a first request to the MN. Here, "intra-FR1 DC" may be understood to mean that both the MCG and the MCG operate in FR1.

[0074] In another implementation, when an MCG FR1 and an SCG FR2 are configured in the terminal and the first request is used to request configuration or rearrangement of an FR1 gap, the terminal may transmit the first request to the MN. Here, "MCG FR1 and SCG FR2" may be understood to mean that the MCG operates in FR1 and the SCG operates in FR2.

[0075] (3) The first request is used to request placement or rearrangement of an FR2 gap.

[0076] In one implementation, when an intra-FR2 DC is configured in a terminal and the first request is used to request configuration or rearrangement of an FR2 gap, the terminal may send a first request to the MN.

[0077] In another implementation, the terminal may further be configured to send a first request to the MN when an MCG FR2 and an SCG FR1 are configured in the terminal and the first request is used to request configuration or rearrangement of an FR2 gap.

[0078] (4) The first request is used to request placement or rearrangement of an MCG gap.

[0079] In one implementation, the terminal may send a first request to the MN when the network equipment indicates that it supports MCG gap placement and the first request is used to request placement or relocation of an MCG gap.

[0080] (5) The first request is used to request placement of an SCG gap when an SN has not been added.

[0081] Here, "SN not added" may be understood to mean that the terminal is not placed in a DC state, but an SCG gap needs to be placed in advance.

[0082] (6) The terminal performed a condition handover (CHO).

[0083] In one implementation, when an MCG gap and / or an SCG gap are configured in a terminal, the terminal performs a condition switch, i.e., switches to a target MN, when a CHO execution condition is met, and at this time, the gap demand of the MCG gap and / or the SCG gap may change, so the terminal can send a first request to the target MN during the switch execution.

[0084] (7) The first request is used to request that the terminal return to the network early during a gap period.

[0085] Here, "early return to the network" may be understood as the terminal returning to the network early when the gap end time or duration of the gap has not yet been reached. "Returning to the network" may also be understood as remaining in the network, or being able to monitor scheduling in the network, or being able to transmit and receive in the network, or being able to monitor channels in the network, etc.

[0086] In one implementation, the first request may be used to indicate that at least the remaining time of the currently used gap is invalidated or at least the remaining time of the current gap is cancelled.

[0087] In another implementation, the first request can further be used to dynamically indicate the gap end time. For example, if the network allocates a long gap, the end time of the gap can be the time when the terminal sends the first request, the time when the network receives the first request, or the time indicated in the first request.

[0088] (8) The first request is used to request the terminal to rearrange a gap during a gap period or to switch a gap.

[0089] In one implementation, assuming that the gap currently used by the terminal is gap A, the terminal can use the fourth instruction information to indicate that gap A needs to be relocated during gap A, or to request switching from gap A to gap B.

[0090] Based on this, when transmitting a first request to the MN, the UE may transmit the first request to the MN via an MCG and / or may transmit the first request to the MN via a split Signaling Radio Bearer (SRB) 1 or SRB 3. For example, in the case of an MCG RLF, the UE may transmit the first request together with MCG failure information when transmitting it to the MN via split SRB 1 or SRB 3.

[0091] In addition, as another possible implementation form of this embodiment, the terminal may send a first request to the SN when the network device includes an SN and at least one of the following (1)-(6) is satisfied.

[0092] (1) The first request is used to request placement or rearrangement of an SCG gap.

[0093] (2) When MCG FR2 and SCG FR1 are configured in the terminal, the first request is used to request the configuration or rearrangement of the FR1 gap.

[0094] Here, "MCG FR2 and SCG FR1" may be understood to mean that when the terminal is placed in the DC state, the MCG operates in FR2 and the SCG operates in FR1.

[0095] (3) When MCG FR1 and SCG FR2 are configured in the terminal, the first request is used to request configuration or rearrangement of the FR2 gap.

[0096] Here, "MCG FR1 and SCG FR2" may be understood to mean that when the terminal is placed in the DC state, the MCG operates in FR1 and the SCG operates in FR2.

[0097] (4) The terminal has performed a conditional master secondary cell change (CPC).

[0098] In one implementation, when an MCG gap and / or an SCG gap are configured in the UE, the terminal performs condition switching, i.e., switches to a target SN, when a CPC execution condition is met, and at this time, the gap demand of the MCG gap and / or the SCG gap may change, so the UE can send a first request to the target SN during CPC execution.

[0099] (5) The terminal needs to return to the network early during the gap period set by the SN.

[0100] (6) During the gap period allocated by the SN, the terminal requests gap rearrangement or gap switching.

[0101] Based on this, when the terminal sends a first request to the SN, it can be realized by any one of the following methods 1 to 3. Method 1: When the terminal is configured with split SRB1 or SRB3 and the SCG in which the terminal is located is in an activated state, the terminal sends the first request to the SN via split SRB1 or SRB3. Method 2: When a split SRB1 or SRB3 is configured in the terminal but the SCG is in a deactivated state, the terminal sends the first request to the SN via the MCG. Method 3: When the terminal is not configured with split SRB1 or SRB3, the terminal sends the first request to the SN via an MCG.

[0102] Furthermore, considering that the network equipment is different, after the network equipment receives the first request sent from the terminal, the network equipment (e.g., MN, SN, or serving base station) may determine the gap configuration information independently, or may determine the gap configuration information through mutual consultation (e.g., MN and SN).

[0103] For example, when the network device includes an MN and gap configuration information needs to be determined by the SN, or when the MN and the SN need to negotiate to determine gap configuration information, the MN sends at least one of the following items (1)-(5) to the SN. (1) At least some of the information included in the first request. For example, only the gap request information related to the SN in the first request may be sent to the SN, or all of the information included in the first request may be sent. (2) At least a portion of the gap allocation information allocated by the MN. For example, the at least a portion of the information may be gap allocation information that indicates only periodic gaps in the gap allocation information. (3) At least a portion of the gap allocation information allocated by the source SN when the SN is the target SN after switching. (4) At least some of the information in the first request received by the source SN when the SN is the target SN after switching. (5) Placement information of the gap that the terminal has requested to use or the gap that the terminal is using.

[0104] Furthermore, for example, when the network equipment includes an SN and gap configuration information needs to be determined by the MN, or when the SN and the MN need to negotiate to determine gap configuration information, the SN sends at least one of the following items (1)-(3) to the MN. (1) At least some of the information included in the first request. (2) At least a portion of the gap placement information placed by the SN. (3) Placement information of the gap that the terminal has requested to use or the gap that the terminal is using.

[0105] Further, for example, when the network equipment includes a first serving base station and gap arrangement information needs to be determined by a second serving base station, or when the first serving base station and the second serving base station need to negotiate to determine gap arrangement information, the first serving base station transmits at least one of the following (1)-(3) to the second serving base station: (1) At least some of the information included in the first request. (2) At least a portion of the gap configuration information configured by the first serving base station. (3) Placement information of the gap that the terminal has requested to use or the gap that the terminal is using.

[0106] In addition, as one possible implementation form, the terminal may send a first request to the network equipment after receiving instruction information sent from the network equipment, where the instruction information is used to indicate that the network equipment supports the terminal's gap request, for example, to indicate that the terminal supports requesting an MCG gap, an SCG gap, a periodic gap, a per UE gap, etc., thereby ensuring the reliability of gap configuration.

[0107] In S320, the terminal receives gap arrangement information transmitted from the network device.

[0108] Here, the gap placement information is used to place or rearrange at least one of the gaps.

[0109] It should be noted that for the implementation procedure of S310, reference can be made to the relevant description in the method embodiment 200. In addition, in one possible implementation form, the gap configuration information may be sent by the network device to the terminal via MCG SRB1, SRB3, or split SRB1. Of course, in this embodiment, the gap configuration information may include at least one of the following items (1)-(7): (1) GAP identifier. (2) Gap type. (3) Gap related time information. (4) Sixth instruction information for instructing the enabling or disabling of at least one gap arrangement. (5) Seventh instruction information for instructing the terminal to release at least one gap arrangement. (6) Eighth instruction information for instructing a DC-related operation mode during the gap period. (7) Ninth instruction information for instructing the terminal to switch the gap.

[0110] Here, for a related explanation about the fact that the gap configuration information may include (1)-(7), please refer to the explanation for the first request above, and detailed explanations will be omitted here to avoid duplication. Here, the ninth indication information may be only 1-bit information instructing gap switching, at which time the terminal switches to a default gap, or the ninth indication information may be several bits instructing an identifier of a target gap to switch to.

[0111] Considering that the gap configuration information is a gap used when the terminal is configured in DC state, as one possible implementation form, at least one of the following items (1)-(9) included in the gap configuration information may be determined by the MN.

[0112] (1) Placement of per UE gap.

[0113] (2) Placement of per FR gap.

[0114] (3) The arrangement of the FR1 gap when an intra-FR1 DC is arranged at the terminal.

[0115] Here, "intra-FR1 DC" may be understood to mean that when the terminal is placed in a DC state, both the MCG and the SCG have serving cells operating in FR1.

[0116] (4) The arrangement of the FR2 gap when an intra-FR2 DC is arranged at the terminal.

[0117] Here, "intra-FR2 DC" may be understood to mean that when the terminal is placed in a DC state, both the MCG and the SCG have serving cells operating in FR2.

[0118] Intra-FR1 DC and intra-FR2 DC may exist simultaneously, in which case the terminal can request a per FR gap.

[0119] (5) The arrangement of the FR1 gap when MCG FR1 and SCG FR2 are arranged at the terminal.

[0120] (6) The arrangement of the FR2 gap when MCG FR2 and SCG FR1 are arranged at the terminal.

[0121] (7) The arrangement of the MCG gap.

[0122] (8) The placement of the one shot gap requested for the MN.

[0123] (9) The allocation of a periodic gap requested for the MN.

[0124] Correspondingly, at least one of the following items (1) to (5) included in the gap placement information is determined by the SN. (1) The arrangement of the FR1 gap when MCG FR2 and SCG FR1 are arranged in the terminal. (2) The arrangement of the FR2 gap when MCG FR1 and SCG FR2 are arranged at the terminal. (3) The location of the SCG gap. (4) The placement of the one shot gap requested for the SN. (5) The requested periodic gap placement for the SN.

[0125] In S330, the terminal allocates or rearranges at least one gap according to the gap allocation information.

[0126] Here, as one possible implementation form, the process of the terminal allocating a gap according to the gap arrangement information may include a step of determining a time unit in which the start time or end time of the gap is located according to the gap arrangement information, and the time unit includes at least one of a system frame number (SFN), a subframe position, a slot position, and a symbol position.

[0127] For example, when a network device places two start time parameters, such as radio frame number information and subframe information, in the gap placement information, T startSFN / T startSubframe where T startSFN is related to the starting radio frame, and T startSubframe T startSFN In this way, the terminal determines the SFN where the gap start time is located and the corresponding subframe in the SFN as T startSFN mod 1024 (or T startSFN ) and T startSubframe can be set to.

[0128] Furthermore, for example, the network device may include a start time parameter, such as T start When the gap start time is set to SFN=T, the UE sets the SFN where the gap start time is located and the corresponding subframe in the SFN. startSFN / 10 and T startSubframeSet mod to 10.

[0129] Furthermore, for example, for a periodic gap, a network device may include a start time parameter T start and the period parameter T priod When the gap start time is set, the terminal sets the SFN where the gap start time is located and the corresponding subframe in the SFN as SFN mod(T priod / 10)=FLOOR(T startSFN / 10) and T startSubframe Can be set to mod 10.

[0130] Furthermore, for example, when the MCG gap and the SCG gap are configured in the terminal, the time unit in which the start time or end time of the MCG gap or the SCG gap is located is determined based on the time difference between the MCG and SCG (for example, SFTD, SFN timing difference) or the time difference between the PCell and PSCell. For example, the terminal calculates the SFN in which the gap start time of the MCG gap is located and the corresponding subframe in the SFN, and determines T startSFNMCG , T startSubframeMCG SFN where the gap start time of the SCG Gap is located and the corresponding subframe in the SFN are T startSFNSCG =T startSubframeMCG +sfnOffset, T startSubframeSCG =T startSubframeMCG +subframeOffset. sfnOffset and subframeOffset are the SFN offset amount and the subframe time domain offset amount between MCG and SCG.

[0131] Based on the above explanation, the gap arrangement procedure provided in this embodiment will be further explained below using Examples 1 to 3. (Example 1)

[0132] Assuming that the terminal needs to request a periodic gap, for example, an MCG periodic gap, an SCG periodic gap, from a network device, the following steps are taken:

[0133] S11: When the terminal receives the first indication information sent from the MN, the terminal sends a first request to the MN via the MCG to request the MN to configure (or allocate) an MCG periodic gap. The first indication information indicates that the terminal can request the MN to configure (or allocate) an MCG periodic gap.

[0134] S12: When the terminal receives the second instruction information sent from the SN, it sends a first request to the SN via SRB3 to request the SN to configure an SCG periodic gap, and the second instruction information is to instruct the terminal that the terminal can request an SCG periodic gap from the SN.

[0135] S13: The terminal receives MCG periodic gap configuration information from the MN and receives SCG periodic gap configuration information from the SN.

[0136] Here, before or after the terminal receives the MCG periodic gap configuration information / SCG periodic gap configuration information, the MN may send the MCG periodic gap configuration to the SN, and the SN may send the SCG periodic gap configuration to the MN.

[0137] S14: The terminal sends a first request to the MN to request modification of the MCG periodic gap arrangement.

[0138] S15: The terminal receives updated MCG periodic gap arrangement information from the MN, and before or after the terminal receives the updated MCG periodic gap arrangement information, the MN may send the updated MCG periodic gap arrangement to the SN. (Example 2)

[0139] Assuming that the terminal needs to request a per UE gap from the network equipment, the following steps are performed.

[0140] S21: When the terminal receives the first indication information sent from the MN, it sends a first request to the MN to request the MN to allocate a per UE gap, and the first indication information is to indicate that the terminal can request a per UE gap.

[0141] S22: The terminal receives per UE gap configuration information from the MN.

[0142] Optionally, during the process in which the network device configures the per UE gap for the terminal, the MN may send a first request and / or per UE gap configuration information to the SN, and the MN may further receive a response to the first request sent from the SN, such as an SN preference on per UE gap.

[0143] S23: The terminal retransmits the first request to the mobile node to request modification of the per UE gap configuration.

[0144] S24: The terminal receives the updated per UE gap configuration information from the MN.

[0145] Optionally, the MN may send updated per UE gap configuration information to the SN before or after the UE receives the updated per UE gap configuration. (Example 3)

[0146] Assuming that the terminal needs to request a per UE gap from the network device for a per CG gap period, the following steps are performed.

[0147] S31: The SN of network A placed an SCG gap at the terminal.

[0148] S32: The terminal transitions to network B during the SCG gap period, monitors paging, and receives a paging message.

[0149] S33: The terminal sends a first request to the MN of network A during the SCG gap period to request per UE gap configuration.

[0150] Optionally, instruct the MN to deactivate or release the SCG gap. Correspondingly, the MN may further instruct the SN that the UE has now deactivated or released the SCG gap.

[0151] S34: The terminal receives per UE gap configuration information configured by the network device.

[0152] S35: per UE gap period, the terminal sends a busy indication in network B.

[0153] In this embodiment, by fully considering whether the terminal is placed in the DC state or not, not only is the flexibility of gap request / placement improved, but the gap granularity can also be made finer (e.g., per UE gap, per FR gap, FR1 gap, FR2 gap, per CG gap, MCG gap, SCG gap, periodic gap, etc.), and the UE communication performance in the DC state is further ensured.

[0154] 4 shows a flowchart of a gap placement method 400 provided in an exemplary embodiment of the present application, which may be performed by a terminal, but is not limited to this, and may be specifically performed by hardware and / or software implemented in the terminal. In this embodiment, the method 400 may include at least the following steps S410, S420, S430, and S440.

[0155] In S410, the terminal sends a first request to the network device.

[0156] The first request is for requesting the network device to configure or reconfigure at least one gap associated with a DC state.

[0157] In S420, the terminal receives gap arrangement information transmitted from the network device.

[0158] The gap placement information is for placing or rearranging at least one of the gaps.

[0159] It should be noted that for the implementation procedures in S410 to S420, reference can be made to the relevant descriptions in the method embodiments 200 and / or 300, and detailed descriptions thereof will be omitted to avoid repetition.

[0160] At S430, the terminal sends a second request to the network device.

[0161] Here, the second request is for requesting the network device to use a target gap, which is at least one gap that has been placed.

[0162] Here, the second request includes at least one of the following items (1) to (3):

[0163] (1) An identifier of the target gap.

[0164] Here, the target gap identifier can be indicated in an implicit or explicit manner.

[0165] (2) The type of the target gap.

[0166] Here, the target gap type may be at least one of per UE gap, per FR gap, FR1 gap, FR2 gap, per CG gap, MCG gap, SCG gap, periodic gap, one shot gap, per direction gap, UL gap, and DL gap.

[0167] (3) The time domain offset required to apply to the start time of the target gap.

[0168] In this embodiment, similar to sending the first request, the terminal can also send a second request to the MN and / or SN, and the MN and / or SN further decide whether to allow the terminal to use the target gap.

[0169] In one implementation, when the network device includes an MN and at least one of the following conditions (1) to (5) is satisfied, the terminal may transmit the second request to the MN.

[0170] (1) The target gap is the gap placed by the MN.

[0171] (2) The target gap is a gap related to the MCG.

[0172] (3) The target gap is a gap placed by the SN, but the SCG is in a deactivated state.

[0173] Here, it can be understood that when there is a Gap in the SCG and the SCG is in a deactivated state, the terminal can perform MSIM tasks without needing the Gap, but considering that the SN does not know whether the terminal uses the Gap, in order to ensure the reliability of data transmission, when downlink data arrives at the SN, the SN needs to initiate an SCG activation flow.

[0174] (4) During the target gap period, the terminal needs to return to the network early.

[0175] (5) During the target gap period, a gap other than the target gap among at least one gap is used or a request is made to switch to another gap.

[0176] Here, assuming that the target gap is per CG gap, during the per CG gap period, the terminal can request per UE gap, for example, if per CG gap is used for paging reception, and as a result, when paging is received, the terminal requests per UE gap to send a busy indication.

[0177] In another implementation form, if the network device includes an SN and at least one of the following (1) to (5) is satisfied, the terminal may send a second request to the SN.

[0178] (1) The target gap is the gap placed by the SN.

[0179] (2) The target gap is a gap related to the SCG. For example, the target gap is a gap placed by the MN, but the target gap is a gap associated with the SCG.

[0180] (3) The target gap is a gap placed by the MN or a gap associated with the MCG, but the MCG is in an unreachable state. Here, the MCG being in an unreachable state may be understood as an MCG radio link failure.

[0181] (4) During the target gap period, the terminal returns to the network early.

[0182] (5) During the target gap period, a gap other than the target gap among at least one gap is used or a request is made to switch to another gap.

[0183] In addition, the second request described in this embodiment can be sent by MAC CE, RRC, or UCI. In one implementation, when an SRB3 or split SRB1 is configured in the terminal and the SCG is in an activated state, the terminal can send the second request to the SN.

[0184] In S440, when the terminal receives response information transmitted from the network device, the terminal uses or does not use the target gap according to the response information.

[0185] It should be noted that in each of the above embodiments, as long as the first request and the second request are transmitted by the terminal during the gap period, the first request or the second request may be a terminal-initiated random access, a scheduling request (SR), a buffer status report (BSR), uplink data, or uplink signaling, etc., and is not limited thereto.

[0186] Based on the above explanation, the gap arrangement procedure in this embodiment will be explained below using Examples 1 and 2. (Example 1)

[0187] Assuming that a terminal needs to request a one shot gap, such as an MCG one shot gap or an SCG one shot gap, from a network device, the following steps are performed.

[0188] S11: When the terminal receives first instruction information sent from the MN, it sends a first request to the MN by MCG to request the MN to allocate an MCG one shot gap, and the first instruction information is to instruct the terminal that it can request an MCG one shot gap from the MN.

[0189] S12: When the terminal receives the second instruction information sent from the SN, it sends a first request to the SN via SRB3 to request the SN to allocate an SCG one shot gap, and the second instruction information is to instruct the terminal that it can request an SCG one shot gap from the SN.

[0190] S13: The terminal receives MCG one shot gap configuration information from the MN and receives SCG one shot gap configuration information from the SN.

[0191] S14: The terminal sends a second request to the SN to request the use of the SCG one shot gap.

[0192] S15: The terminal uses SCG one shot gap to switch to another SIM's network and execute the service.

[0193] S16: If the terminal returns to the network early during the SCG one shot gap operation period, the terminal can perform one of the following items (1)-(6). (1) Initiate random access to SN. (2) Send SR to SN. (3) Send a BSR to the SN. (4) Transmit uplink data to SN. (5) Send other uplink signaling to the SN. (6) A return notification is sent to the MN. (Example 2)

[0194] Assuming that the terminal needs to request a per UE gap from the network device for a per CG gap period, the following steps are performed.

[0195] S21: The SN of network A placed an SCG gap at the terminal.

[0196] S22: The terminal transitions to network B during the SCG gap period, monitors paging, and receives a paging message.

[0197] S23: The terminal sends a second request to the MN of network A during the SCG gap period to request the use of the configured per UE gap.

[0198] Optionally, instruct the MN to deactivate or release the SCG gap. Correspondingly, the MN may further instruct the SN that the UE has now deactivated or released the SCG gap.

[0199] In this embodiment, when gap placement information is requested from a network device by a first request, a second request is further made to the network device to request the use of a target gap. This not only improves the flexibility of gap placement, but also maintains synchronization of the transmission and reception status between the terminal and the network device, thereby preventing data scheduled to a certain node from being missed when the terminal switches to another network to execute a service.

[0200] 5 shows a flowchart of a gap placement method 500 provided in an exemplary embodiment of the present application, which may be performed by, but is not limited to, a network device, and may be specifically performed by hardware and / or software implemented in the network device. In this embodiment, the method 500 may include at least the following steps S510 and S520.

[0201] At S510, a network device receives a first request sent from a terminal to request the network device to configure or reconfigure at least one gap associated with a DC state.

[0202] At S520, the network device sends gap allocation information to the terminal.

[0203] Here, the gap configuration information is used by the terminal to configure or reconfigure at least one of the gaps. In one possible implementation, when the terminal is configured in a DC state, the network equipment includes a master node MN or a secondary node SN, and the gap configuration information is determined by the MN and / or the SN, and when the terminal is not configured in a DC state, the network equipment deviceincludes a first serving base station that provides access service to the terminal, and the gap allocation information is determined by the first serving base station and / or a second serving base station that includes at least one candidate SN.

[0204] In another possible implementation form, the first request includes at least one of: first instruction information for indicating a request type of the first request, including at least one of a gap identifier, a gap type, associated time information of the gap, adding a gap configuration, modifying a gap configuration, and releasing a gap configuration; second instruction information for requesting enabling or disabling of at least one gap; third instruction information for instructing the terminal to return to the network early during the gap period; fourth instruction information for instructing the terminal to request gap relocation during the gap period or request gap switching during the gap period; and fifth instruction information for instructing a dual connectivity DC-related operation mode of the terminal during the gap period.

[0205] In another possible implementation, the gap type includes at least one of per UE gap, per FR gap, FR1 gap, FR2 gap, per CG gap, MCG gap, SCG gap, periodic gap, one shot gap, gap in each transmission direction, UL gap, DL gap.

[0206] In another possible implementation, the relevant time information of the gap includes at least one of a gap length, a gap period, a gap start time, a gap end time, and a gap scale factor.

[0207] In another possible implementation form, the gap configuration information includes at least one of a gap identifier, a gap type, associated time information of the gap, sixth instruction information for instructing the terminal to enable or disable at least one gap configuration, seventh instruction information for instructing the terminal to release at least one gap configuration, eighth instruction information for instructing a DC-related operating mode during the gap period, and ninth instruction information for instructing the terminal to switch the gap.

[0209] In another possible implementation form, at least one of the items included in the gap arrangement information, such as the arrangement of the FR1 gap when MCG FR2 and SCG FR1 are arranged in the terminal, the arrangement of the FR2 gap when MCG FR1 and SCG FR2 are arranged in the terminal, the arrangement of the SCG gap, the arrangement of the one-shot gap requested to the SN, and the arrangement of the periodic gap requested to the SN, is determined by the SN.

[0210] In another possible implementation form, the MN transmits to the SN at least one of the following items: at least some of the information included in the first request, at least some of the information in the gap configuration information configured by the MN, at least some of the information in the gap configuration information configured by the source SN when the SN is the target SN after switching, at least some of the information in the first request received by the source SN when the SN is the target SN after switching, and configuration information of the gap that the terminal has requested to use or configuration information of the gap that the terminal is using.

[0211] In another possible implementation form, the SN transmits to the MN at least some of the information included in the first request, at least some of the information in the gap configuration information configured by the SN, and configuration information of the gap that the terminal has requested to use or configuration information of the gap that the terminal is using.

[0212] In another possible implementation form, the method further includes a step in which the network device receives a second request sent from the terminal to request the network device to use a target gap belonging to at least one of the gaps, and a step in which the network device sends response information to the terminal to instruct the terminal to use or not use the target gap.

[0213] In another possible implementation, the second request includes at least one of an identifier of the target gap, a type of the target gap, and a time domain offset amount required to be applied to the start time of the target gap.

[0214] It should be noted that for the implementation steps of each implementation mode provided in this embodiment, reference can be made to the relevant descriptions in the method embodiments 200-400, and in order to avoid repetitive description, this embodiment will not describe them in detail.

[0215] In this embodiment, by taking into full consideration whether the terminal is placed in a DC state or not and then requesting gap placement from the corresponding network equipment, flexible gap placement can be realized according to the DC state, thereby avoiding problems such as the transmission of gap placement-related information between network interfaces, reducing gap request / placement delays and system signaling overhead, and improving the communication performance of the UE in the DC state (or architecture).

[0216] It should be noted that the gap placement method 200-500 provided in the embodiments of the present application may be performed by a gap placement device or a control module for executing the gap placement method 200-500 in the gap placement device. The gap placement device provided in the embodiments of the present application will be described by taking the gap placement device performing the gap placement method 200-500 as an example.
