[0004] Extended reality (XR) refers to all combinations of real and virtual environments and human-computer interactions created by computer technology and wearable devices. It includes various forms such as augmented reality (AR), mixed reality (MR), and virtual reality (VR), as well as the intersections between them. For VR services, uplink transmission primarily uses dense small data packet transmission, while downlink transmission mainly involves multimedia data transmission such as video and audio. Downlink video data generally requires a very high data rate. For AR services, in addition to dense small data packet transmission, uplink transmission may also include multimedia data such as video, audio, and scene images. The downlink data transmission characteristics are basically the same as those of VR services.

It should be noted that this application embodiment only uses a base station in an NR system as an example for description and does not limit the specific type of base station.

[0059] The following description, in conjunction with the accompanying drawings, details the method for sending and receiving data by a control terminal, the network-side device, and the terminal provided in this application, through some embodiments and application scenarios.

[0060] Figure 2 shows a flowchart of a method for a control terminal to send and receive data according to an embodiment of this application. This method 200 can be executed by a network-side device. As shown in Figure 2, the method may include step S202 and / or step S204. The figure illustrates an example including steps S202 and S204.

[0061] S202: The network-side device sends a first DCI to the terminal on the first serving cell. The first DCI does not contain a first indication field. The first DCI indicates that the terminal should not skip the first gap and / or restriction occasion corresponding to the first serving cell.

[0062] The first serving cell may correspond to the first interval, or the first serving cell may correspond to the restriction time, or the first serving cell may correspond to both the first interval and the restriction time.

[0063] S204: The network-side device sends a second DCI to the terminal on the first serving cell. The second DCI includes a first indication field, which is used to indicate whether the terminal skips the first gap and / or restriction occasion corresponding to the second serving cell.

[0064] The first indication field in this embodiment can also be understood as an information field indicating gap / restriction occasion skipping. Specifically, the first indication field is used to indicate whether the terminal skips the first interval and / or restriction occasion corresponding to the second serving cell.

[0065] In this embodiment, "the terminal does not skip the first interval and / or the restriction period" means that the terminal can perform measurement operations within the first interval and / or the restriction period (whether the terminal performs measurement operations can be determined by the terminal itself), and the terminal will not transmit or receive data. "The terminal skips the first interval and / or the restriction period" means that the terminal can refrain from measurement within the first interval and / or the restriction period; that is, the terminal can transmit or receive data (whether the terminal transmits or receives data depends on the base station's configuration or scheduling). Therefore, this method of indicating whether the terminal skips the first interval and / or the restriction period can control whether the terminal transmits or receives data.

[0066] In this embodiment of the application, the terminal transmits and receives data during the first interval and / or the restricted time, which may include at least one of the following: detecting the Physical Downlink Control Channel (PDCCH), receiving the Physical Downlink Shared Channel (PDSCH), receiving the Channel State Information Reference Signal (CSI-RS), transmitting the Physical Uplink Shared Channel (PUSCH), transmitting the Physical Uplink Control Channel (PUCCH), and transmitting the Sounding Reference Signal (SRS), etc.

[0067] In this embodiment of the application, the first DCI is a scheduling DCI format that does not include the first indication field, and the second DCI is a DCI format that includes the first indication field. The DCI format is a DCI format for scheduling PUSCH or PDSCH transmission.

[0068] Among them, the scheduling DCI format that does not include the first indication field may include at least one of the following: fallback DCI format, scheduling DCI format with non-configurable DCI field (DCI format that can schedule data transmission), and DCI format without a configured first indication field.

[0069] The scheduling DCI format may include at least one of the following: DCI format 0_0, DCI format 1_0, DCI format 0_1, DCI format 1_1, DCI format 2_0, DCI format 2_1, DCI format 3_0, DCI format 3_1, DCI format 4_0, DCI format 4_1, and DCI format 4_2.

[0070] The fallback DCI format may include at least one of the following: DCI format 0_0 and DCI format 1_0.

[0071] Among them, the scheduling DCI format that is not configurable in the DCI domain may include at least one of the following: DCI format 4_0, DCI format 4_1.

[0072] The second DCI includes at least one of the following: a multi-carrier scheduling DCI format, and a DCI domain-configurable scheduling DCI format. The second DCI may include scheduling DCI formats other than DCI format 0_0 and DCI format 1_0.

[0073] The multi-carrier scheduling DCI format may include at least one of the following: DCI format 0_3 and DCI format 1_3.

[0074] The configurable scheduling DCI format in the DCI domain can include at least one of the following: DCI format 0_1, DCI format 1_1, DCI format 0_2, DCI format 2_1, DCI format 3_1, and DCI format 4_2. Multi-carrier scheduling DCI can schedule serving cells across multiple frequency ranges, each of which can include one or more serving cells, without specific limitations.

[0075] Additionally, it should be noted that in the prior art, the fields included in DCI format 4_0 and DCI format 4_1 are predefined and cannot be configured. However, both of these DCI formats contain some reserved bits. For example, DCI 4_0 has 14 reserved bits, and DCI 4_1 has 3 reserved bits. In the prior art, these reserved bits exist for DCI size alignment and do not contain any information. In one implementation, when gap / restriction skipping is enabled on the terminal, one or more reserved bits can be used to indicate whether the UE should perform gap / restriction skipping. In this embodiment, DCI format 4_0 or DCI format 4_1 contains a corresponding indication field, which should belong to the second DCI format.

[0076] In this application embodiment, the above method may include the following first method and / or second method:

[0077] The first method: The first DCI instructs the terminal not to skip the first interval or restriction point corresponding to the first serving cell, which is after the end position of the first DCI and where the start position is at least a preset time interval from the end position. In this method, the preset time interval Toffset related to the first DCI can be set as needed, and the specific value is not limited.

[0078] The second method: The first indication field is used to indicate whether the terminal should skip the first interval or restriction opportunity corresponding to the second serving cell after the end position of the second DCI and where the start position is not less than a preset time interval from the end position. In this method, the preset time interval Toffset related to the second DCI can be set as needed, and the specific value is not limited.

[0079] In this embodiment, the first indication field in the second DCI may include 1 bit of information, which saves the size of the DCI. Alternatively, the first indication field in the second DCI may include multiple bits of information, which allows for more precise indication by distinguishing different bits. In practical applications, the implementation method of using 1 bit of information or multiple bits of information can be selected according to different scenarios, and there is no specific limitation.

[0080] In one scenario, the first indication field in the second DCI may include 1 bit of information, and the above method may include one of the following:

[0081] 1) The second serving cell includes the first serving cell, and the first indication field is used to indicate whether the terminal skips the first interval and / or restriction time corresponding to the first serving cell. In this case, the first indication field is used to indicate the first interval and / or restriction time corresponding to the scheduling cell.

[0082] 2) The second serving cell includes a target scheduled cell. The first indication field is used to indicate whether the terminal should skip the first interval and / or restriction time corresponding to the target scheduled cell. The target scheduled cell is one or more cells scheduled by the second DCI. In this case, the first indication field has the ability to indicate all cells scheduled by the second DCI. When making a specific indication, one or more cells can be selected as the target scheduled cell as needed to initiate the corresponding indication to the terminal. This approach allows for more flexible indication.

[0083] For example, among all the cells scheduled by the second DCI, the first indication field can indicate whether the terminal should skip the first interval and / or restriction time corresponding to one or more cells, while no indication is given for the remaining cells.

[0084] The target scheduled cell can be determined by at least one of the following: a preset rule (e.g., the cell with the largest or smallest index among all scheduled cells, or the cell corresponding to the gap occasion that is no earlier than the preset time interval Toffset after the DCI and closest to the end position of the DCI), a Radio Resource Control (RRC) configuration, or an indication of the second DCI.

[0085] In one implementation, the target scheduled cell includes multiple cells scheduled by the second DCI, and the first indication field, including 1 bit of information, can be used for:

[0086] Indicates whether the terminal should skip the first interval or restriction opportunity after the end position of the second DCI for each scheduled cell in the target scheduled cell and the start position is not less than a preset time interval from the end position.

[0087] In this case, 1 bit of information can be used to indicate multiple cells, which can save the size of the second DCI.

[0088] In this context, the preset time interval for each scheduled cell in the target scheduled cell is independent. That is, the preset time interval for each scheduled cell can be determined independently. The preset time intervals for each scheduled cell can be the same or different; there is no specific limitation.

[0089] In another scenario, the first indication field in the second DCI may include multi-bit information, and the above method may include one of the following:

[0090] 1) The bits in the multi-bit information correspond one-to-one with the multiple cells that can be scheduled by the second DCI. The base station selects the target bit in the first indication field to indicate whether the terminal skips the first interval and / or restriction time corresponding to the target cell corresponding to the target bit. The target bit is one or more bits in the multi-bit information.

[0091] In this case, the number of bits in the multi-bit information is the same as the maximum number of cells that can be scheduled by the second DCI. By selecting one or more target bits, it is possible to provide instructions separately for some or all of the cells that can be scheduled by the second DCI, which is a relatively flexible approach.

[0092] 2) The bits in the multi-bit information correspond one-to-one with the multiple frequency ranges that can be scheduled by the second DCI. The base station selects the target bit in the first indication field to indicate whether the terminal should skip the first interval and / or restriction opportunity corresponding to the serving cell in the frequency range corresponding to the target bit. The target bit is one or more bits in the multi-bit information.

[0093] In this case, the number of bits in the multi-bit information is the same as the maximum number of frequency ranges that the second DCI can schedule. By selecting one or more target bits, it is possible to indicate a portion or the entire frequency range within the frequency range that the second DCI can schedule, providing a relatively flexible approach.

[0094] In one implementation, the target bit includes multiple bits from multi-bit information, and the target bit corresponds to multiple frequency ranges. The first indication field uses the target bit for indication.

[0095] Whether the terminal skips the first interval or restriction opportunity after the end position of the serving cell in each of the multiple frequency ranges corresponding to the target bit and the start position is not less than a preset time interval from the end position in the second DCI.

[0096] Within the second DCI schedulable frequency range, each frequency range corresponds to its own preset time interval. In other words, the preset time interval for each frequency range can be determined independently. The preset time intervals for each frequency range can be the same or different; there is no specific limitation.

[0097] In this embodiment of the application, the first DCI may indicate intervals and / or timing restrictions that have temporal conflicts, or it may indicate intervals and / or timing restrictions that have the same starting position.

[0098] When a network-side device determines that a time-domain conflict exists, it can handle the conflict based on the priority configured for the measurement interval and / or constraint timing. Specifically, this can include: applying the corresponding higher-priority measurement interval and / or constraint timing (effective), and abandoning the corresponding lower-priority measurement interval and / or constraint timing (ineffective). Each of the two measurement intervals and / or constraint timings determined to have a time-domain conflict has a corresponding priority, and these priorities are different.

[0099] In this embodiment of the application, the aforementioned time-domain conflict includes at least one of the following: time-domain overlap, and time-domain interval less than a specified threshold. That is, the interval with a time-domain conflict includes: an interval with time-domain overlap, and / or an interval with a time-domain interval less than a specified threshold. The timing for limiting time-domain conflicts includes: timing for limiting time-domain overlap, and / or timing for limiting time-domain intervals less than a specified threshold.

[0100] The specified threshold can be set as needed, such as 4ms, but this application embodiment does not impose a specific limitation on it.

[0101] In this embodiment of the application, the first DCI can be used for one of the following:

[0102] 1) Instruct the terminal not to skip all first intervals and / or restriction opportunities corresponding to the time domain conflict of the first serving cell, wherein the first serving cell has multiple intervals and / or restriction opportunities with time domain conflicts;

[0103] 2) Instruct the terminal not to skip any first intervals and / or restriction opportunities corresponding to the same starting position of the first serving cell;

[0104] 3) Instruct the terminal not to skip the first interval and / or restriction timing after time-domain conflict resolution for the first serving cell, wherein the first serving cell has multiple intervals and / or restriction timings with time-domain conflicts. Time-domain conflict resolution refers to selecting the interval and / or restriction timing with higher priority as the first interval and / or restriction timing after time-domain conflict resolution.

[0105] In this embodiment of the application, the first indication field in the second DCI can be used for one of the following:

[0106] 1) Instructing the terminal whether to skip all first intervals and / or restriction opportunities of time-domain conflict corresponding to the second serving cell, wherein the second serving cell has multiple intervals and / or restriction opportunities of time-domain conflict;

[0107] 2) Instruct the terminal whether to skip all first intervals and / or restriction opportunities corresponding to the same starting position of the second serving cell;

[0108] 3) Instructs the terminal whether to skip the first interval and / or restriction timing after time-domain conflict handling for the second serving cell, wherein the second serving cell has multiple intervals and / or restriction timings with time-domain conflicts. Time-domain conflict handling refers to selecting the interval and / or restriction timing with higher priority as the first interval and / or restriction timing after time-domain conflict handling.

[0109] In this embodiment of the application, the above method may include one of the following:

[0110] 1) The second serving cell corresponds to multiple concurrent measurement gaps and / or restriction times for time-domain conflicts. The first indication field is used to indicate whether the terminal skips the interval and / or restriction time after the time-domain conflict handling.

[0111] 2) Multiple non-concurrent intervals and / or restriction opportunities for time-domain conflicts corresponding to the second serving cell, the first indication field is used to indicate whether the terminal skips all intervals and / or restriction opportunities for time-domain conflicts corresponding to the second serving cell, or the first indication field is used to indicate whether the terminal skips all first intervals and / or restriction opportunities for the same starting position corresponding to the second serving cell.

[0112] In this embodiment of the application, the first interval and / or restriction timing may be an interval and / or restriction timing that is allowed to be skipped, configured by the network-side device or reported by the terminal.

[0113] In this embodiment of the application, the above method may further include: the network-side device receiving capability information reported by the terminal, which may include one of the following:

[0114] 1) The terminal supports the first mode;

[0115] 2) The terminal supports the second mode;

[0116] 3) The terminal supports a third mode;

[0117] 4) The terminal supports both the first and second modes;

[0118] 5) The terminal supports both the second and third modes;

[0119] The first mode and the second mode both include: when the first indication field is a first value, it is used to instruct the terminal to skip the first interval and / or restriction time corresponding to the second serving cell; when the first indication field is a second value, it is used to instruct the terminal not to skip the first interval and / or restriction time corresponding to the second serving cell, or to instruct the terminal to maintain the same behavior as before within the first interval and / or restriction time corresponding to the second serving cell.

[0120] The first mode further includes: if the first indication field is a first value, then the first indication field in the DCI indicating the first interval and / or the DCI limiting the timing after the second DCI is also a first value.

[0121] The second mode further includes: if there are multiple second DCIs that indicate the first interval and / or the timing of the restriction through the first indication field, the terminal determines whether to skip the first interval and / or the timing of the restriction based on the last received second DCI.

[0122] The third mode includes: when the first indication field is a first value, it is used to instruct the terminal to skip the first interval and / or restriction timing corresponding to the second serving cell; when the first indication field is a second value, it represents reserved bit information or indication information that the terminal ignores the indication field.

[0123] In addition, in the various modes described above, the first indication field can be 1 bit of information or multiple bits of information. When the first indication field is 1 bit of information, for example, the first value can be 1 and the second value can be 0, or the first value can be 0 and the second value can be 1. This application embodiment does not specifically limit this.

[0124] When the first indication field is multi-bit information, for any one of the bits, for example, the first value can be 1 and the second value can be 0, or the first value can be 0 and the second value can be 1. This application embodiment does not specifically limit this.

[0125] In this embodiment of the application, the terminal may determine the last received second DCI in any of the following ways:

[0126] 1) The method of determining the PUCCH resource for Hybrid Automatic Repeat request-Acknowledgement (HARQ-ACK) in NR is the same. For details, please refer to the relevant NR protocol.

[0127] 2) The method determines the order based on at least one of the following: sorting by PDCCH monitoring occasion, sorting by serving cell index, sorting by control resource set pool index, and sorting by frequency (high to low). The sorting by monitoring occasion can be from front to back, the sorting by index can be from small to large, and the sorting by frequency can be from low to high, etc., without specific limitations.

[0128] The method provided in this application embodiment involves a network-side device sending a first downlink control information (DCI) to a terminal on a first serving cell. The first DCI does not include a first indication field and indicates that the terminal does not skip the first interval and / or restriction time corresponding to the first serving cell. Alternatively, the network-side device sends a second DCI to the terminal on the first serving cell, and the second DCI includes a first indication field. The first indication field is used to indicate whether the terminal skips the first interval and / or restriction time corresponding to the second serving cell. This provides a solution for how to indicate whether the terminal skips a certain interval and / or restriction time, thereby controlling the terminal's data transmission and reception and improving the effectiveness of the communication system.

[0129] Figure 3 illustrates a flowchart of a method for a control terminal to send and receive data according to an embodiment of this application. This method 300 can be executed by a network-side device. As shown in Figure 3, taking the sending of a first DCI as an example, the method may include the following steps.

[0130] S302: The network-side device sends a first DCI to the terminal on the first serving cell. The first DCI does not contain a first indication field. The first DCI indicates that the terminal should not skip the first interval or restriction time corresponding to the first serving cell after the end position of the first DCI and where the start position is not less than a preset time interval from the end position.

[0131] In this embodiment of the application, the first DCI is a scheduling DCI format that does not include the first indication field, and the second DCI is a DCI format that includes the first indication field. The DCI format is a DCI format for scheduling PUSCH or PDSCH transmission.

[0132] The scheduling DCI format that does not include the first indication field may include at least one of the following: a rollback DCI format, a scheduling DCI format where the DCI field is not configurable, or a DCI format where the first indication field is not configured.

[0133] The fallback DCI format may include at least one of the following: DCI format 0_0, DCI format 1_0.

[0134] The scheduling DCI format with a non-configurable DCI field can include at least one of the following: DCI format 4_0 and DCI format 4_1. For some DCI formats, such as fallback DCI, in order to ensure the size of the DCI during RRC reconfiguration, the information fields are often predefined by the protocol and cannot be configured through RRC. Some DCI formats have configurable information fields, but the base station can configure the UE not to include the first indication field. Since fallback DCI and scheduling DCI formats with a non-configurable DCI field, or some DCI formats that do not have a configured first indication field, do not contain information fields that explicitly indicate gap / restriction occasion skipping, this application embodiment uses fallback DCI formats and / or scheduling DCI formats that do not contain the corresponding indication field to directly indicate whether the UE should perform gap / restriction occasion skipping.

[0135] The above method, based on the end position of the DCI and the preset time interval, solves the problem of how a DCI that does not contain a corresponding indication field (the field indicating gap / restriction occasion skipping) can indicate whether a gap / restriction occasion is skipping. This enables control over the terminal's data transmission and reception, improving the effectiveness of the communication system.

[0136] Figure 4 illustrates a flowchart of a method for a control terminal to send and receive data according to an embodiment of this application. This method 400 can be executed by a network-side device. As shown in Figure 4, taking the transmission of a second DCI as an example, the method may include the following steps.

[0137] S402: The network-side device sends a second DCI to the terminal on the first serving cell. The second DCI includes a first indication field. The first indication field is used to indicate whether the terminal skips the first interval or restriction opportunity corresponding to the second serving cell after the end position of the second DCI and the start position is not less than a preset time interval from the end position.

[0138] In this embodiment, the second DCI includes at least one of the following: a multi-carrier scheduling DCI format and a DCI domain-configurable scheduling DCI format. The multi-carrier scheduling DCI format includes at least one of the following: DCI format 0_3 and DCI format 1_3. The DCI domain-configurable scheduling DCI format may include at least one of the following: DCI format 0_1, DCI format 1_1, DCI format 0_2, DCI format 2_1, DCI format 3_1, and DCI format 4_2.

[0139] Optionally, in this embodiment, the second DCI includes at least one of the following: DCI format 4_0, DCI format 4_1. For DCI format 4_0 or DCI format 4_1, the first indicator field may be a reserved bit in the prior art.

[0140] For the information field indicating gap / restriction occasion skipping, i.e., the first indication field, this information field should be configurable, considering that not all UEs support it, or that UEs do not always need gap / restriction occasion skipping, or to save DCI size. For example, for DCI formats 0_1, 1_1 and DCI formats 0_2, 1_2, 4_2, the base station can configure whether this information field exists for each DCI format through RRC parameters.

[0141] The above method, based on the end position of DCI and the preset time interval, solves the problem of how DCI containing the corresponding indication field indicates whether gap / restriction occasions are skipped, thereby controlling the terminal's data transmission and reception and improving the effectiveness of the communication system.

[0142] Figure 5 illustrates a schematic diagram of DCIs without corresponding indication fields and DCIs with corresponding indication fields provided in this application embodiment. As shown in Figure 5, five scenarios are included. In the first scenario, there are two DCIs with corresponding indication fields. The first indication field of the two DCIs includes one bit with a value of 1, which is used to indicate that the terminal skips the first gap or restriction occasion corresponding to the second serving cell. As can be seen from the figure, this is specifically the first gap or restriction occasion after a preset time interval T_offset between the starting position and the ending position of the DCI.

[0143] In the second scenario, the first is the second DCI (including a first indicator field with a value of 1 for 1 bit), and the second is the backoff DCI (not including the first indicator field). The backoff DCI is used to instruct the terminal not to skip the first interval and / or restriction timing corresponding to the first serving cell. As can be seen from the figure, it is specifically the first interval or restriction timing after the preset time interval T_offset between the starting position and the end position of the backoff DCI.

[0144] In the third scenario, there are two backoff DCIs, excluding the first indication field, which are used to instruct the terminal not to skip the first interval and / or restriction timing corresponding to the first serving cell. As shown in the figure, specifically, it is the first interval or restriction timing after the preset time interval T_offset between the starting position and the end position of the last backoff DCI.

[0145] In the fourth scenario, the first is the second DCI (including a first indicator field with a value of 1 for 1 bit), and the second is the back-off DCI (not including the first indicator field). The back-off DCI is used to instruct the terminal not to skip the first interval and / or restriction timing corresponding to the first serving cell. As can be seen from the figure, it is specifically the first interval or restriction timing after the preset time interval T_offset between the starting position and the end position of the back-off DCI.

[0146] In the fifth scenario, there are two second DCIs. The first DCI includes a first indication field with a value of 1, and the second DCI includes a first indication field with a value of 0. The second DCI is used to indicate that the terminal should not skip the first interval or restriction opportunity corresponding to the second serving cell. As shown in the figure, it is specifically the first interval or restriction opportunity after a preset time interval T_offset between the start position and the end position of the DCI.

[0147] Figure 6 illustrates a flowchart of a method for a control terminal to send and receive data according to an embodiment of this application. This method 600 can be executed by a network-side device. As shown in Figure 6, taking the sending of a second DCI and the first indication field including 1 bit of information as an example, the method may include the following steps.

[0148] S602: The network-side device sends a second DCI to the terminal on the first serving cell. The second DCI contains a first indication field, which includes 1 bit of information to indicate whether the terminal skips the first serving cell or the first interval and / or the restriction time corresponding to the target scheduled cell.

[0149] The above method includes two scenarios as follows:

[0150] 1) The second serving cell includes the first serving cell (scheduling cell), and the first indication field is used to indicate whether the terminal skips the first interval and / or restriction time corresponding to the first serving cell.

[0151] 2) The second serving cell includes the target scheduled cell, and the first indication field is used to indicate whether the terminal skips the first interval and / or the restriction time corresponding to the target scheduled cell.

[0152] In this embodiment, the second DCI can be a multi-carrier scheduling DCI format, including DCI format 0_3 and / or DCI format 1_3. The multi-carrier scheduling DCI can schedule the UE to transmit PUSCH or receive PDSCH on multiple cells. The scheduled cell can be indicated by the scheduled cells indicator field in the multi-carrier scheduling DCI.

[0153] In this embodiment of the application, for DCI formats 0_3 and 1_3, network-side devices such as base stations can configure whether they include an information field for indicating gap / restriction occasion skipping through higher-layer parameters. For example, the base station can configure whether DCI formats 0_3 and 1_3 include this information field, and configure whether the information field includes 1 bit or more bits, under IE PDSCH-config and PUSCH-config, respectively.

[0154] In this embodiment of the application, the target scheduled cell can be one or more cells scheduled by the second DCI. The target scheduled cell can be determined by at least one of the following: preset rules, radio resource control configuration, and indication from the second DCI.

[0155] For example, the target scheduled cell can be any of the following cells determined according to preset rules: the first scheduled cell, the last scheduled cell, the cell with the largest or smallest index among all scheduled cells, or the cell corresponding to the nearest gap / restriction occasion after the preset time interval Toffset after DCI. Alternatively, the target scheduled cell can be multiple scheduled cells configured in RRC, etc.

[0156] In one implementation, the target scheduled cells include multiple cells scheduled by the second DCI. Accordingly, the first indication field can be specifically used to indicate whether the terminal skips a first interval or restriction opportunity after the end position of the second DCI for each of the target scheduled cells and where the start position is at least a preset time interval from the end position. That is, the indication of the first indication field applies to all target scheduled cells.

[0157] In this context, the preset time interval for each scheduled cell in the target scheduled cell is independent. That is, the preset time interval for each scheduled cell can be determined independently. The preset time intervals for each scheduled cell can be the same or different; there is no specific limitation.

[0158] In another implementation, the target scheduled cell includes cells within multiple frequency ranges scheduled by the second DCI. Accordingly, the first indication field can be specifically used to indicate whether the terminal skips a first interval or restriction opportunity corresponding to a cell in each of the multiple frequency ranges after the end position of the second DCI and where the start position is at least a preset time interval from the end position. That is, the indication of the first indication field applies to cells in all frequency ranges.

[0159] Figure 7 illustrates a schematic diagram of the DCI using 1 bit information for indication provided in this embodiment of the application. Referring to Figure 7, the UE is configured with a per-FR measurement gap as an example. The DCI format on cell 0 can schedule cells 0, 1, and 2. The frequency ranges of cells 0, 1, and 2 include FR1 and FR2; the frequency domains of cells 0 and 1 belong to FR1, and the frequency domain of cell 2 belongs to FR2. Gap configuration 1 is the FR1 gap configuration (i.e., the gap configuration for FR1 measurement), and gap configuration 2 is the FR2 gap configuration (i.e., the gap configuration for FR2 measurement). The base station transmits a DCI 0_3 or 1_3 on cell 0, where the Scheduled cells indicator field indicates that the DCI schedules PUSCH / PDSCH transmission on cells 0 and 2. This DCI 0_3 or 1_3 contains a 1-bit information field to indicate gap / restriction skipping.

[0160] In one implementation, the aforementioned 1-bit information can be applied to the scheduling cell, i.e., cell 0. When the value of this bit is 1, it can instruct the UE to skip the first gap occasion in cell 0 after the DCI end position and where the start position is at least a preset time interval T_offset1 from the end position. Optionally, since cell 1 in FR1 corresponds to the same gap occasion as cell 0, the value of this bit is also 1, which can simultaneously instruct the UE to skip the first FR1 gap in cell 1 after the DCI end position and where the start position is at least a preset time interval T_offset1 from the end position. In this scenario, the first indication field in the DCI is effective for all cells within a certain frequency range. Therefore, in cells 0 and 1, the UE can transmit and receive data in a gap-free manner on the skipped FR1 gap. Optionally, no measurements are performed, such as detecting PDCCH, receiving PDSCH or CSI-RS, and sending PUSCH, PUCCH, SRS, etc.

[0161] In another implementation, the aforementioned 1-bit information can be applied to all scheduled cells, namely cells 0 and 2, as shown by the two curves with arrows in the figure. When the value of this bit is 1, it instructs the UE to skip the first gap occasion in cell 0 after the DCI end position and where the start position is at least a preset time interval T_offset1 from the end position. It also instructs the UE to skip the first gap occasion in cell 2 after the DCI end position and where the start position is at least a preset time interval T_offset2 from the end position. In this scenario, the first indication field in the DCI is effective for all scheduled cells. Therefore, within cells 0 and 2, the UE can transmit and receive data in a gap-free manner on the skipped FR1 and FR2 gaps, respectively, without performing measurements, such as detecting PDCCH, receiving PDSCH or CSI-RS, and sending PUSCH, PUCCH, SRS, etc. Optionally, since cell 1 and cell 0 within FR1 correspond to the same gap occasion, the UE can also be instructed to skip the first FR1 gap in cell 1 after the DCI end position, provided that the start position is at least a preset time interval T_offset1 from the end position. In this scenario, the first indication field in the DCI is effective for all cells within a certain frequency range. Therefore, within cell 0 and cell 1, the UE can transmit and receive data in a gap-free manner on the skipped FR1 gap. Optionally, measurements can be omitted, such as detecting PDCCH, receiving PDSCH or CSI-RS, and transmitting PUSCH, PUCCH, SRS, etc.

[0162] It is worth mentioning that the time intervals T_offset1 and T_offset2 mentioned above can be the same or different, such as being defined or determined independently, and there are no specific restrictions.

[0163] In another implementation, the aforementioned 1-bit information can be applied to a scheduled cell, such as the cell with the smallest or largest cell index among the scheduled cells according to predefined rules, or a cell explicitly configured or indicated by the base station. For example, this 1-bit information is used to indicate one of the scheduled cells 0 and 2, specifically cell 0. When the value of this bit is 1, it can instruct the UE to skip the first FR1 gap in cell 0 that is after the DCI end position and after the start position is at least T_offset1 from the end position. Therefore, within cell 0, the UE can transmit and receive data in a gap-free manner without performing measurements, such as detecting PDCCH, receiving PDSCH or CSI-RS, and sending PUSCH, PUCCH, SRS, etc. Optionally, since cell 1 and cell 0 correspond to the same gap in FR1, the value of this bit can also simultaneously instruct the UE to skip the first FR1 gap in cell 1 that is after the DCI end position and after the start position is at least a preset time interval T_offset1 from the end position. Therefore, within cell 1, the UE can transmit and receive data in a way that does not involve a gap on the skipped gap, without performing measurements, such as detecting PDCCH, receiving PDSCH or CSI-RS, and sending PUSCH, PUCCH, SRS, etc.

[0164] The above method can indicate multiple cells with just 1 bit of information, which is flexible. Moreover, based on the end position of DCI and the preset time interval, it solves the problem of how to indicate whether gap / restriction occasions are skipped in multi-carrier modulation DCI, thereby controlling the terminal's data transmission and reception and improving the effectiveness of the communication system.

[0165] Figure 8 shows a flowchart of a method for a control terminal to send and receive data according to an embodiment of this application. This method 800 can be executed by a network-side device. As shown in Figure 8, taking the sending of a second DCI and the first indication field including multi-bit information as an example, the method may include the following steps S802 and / or S804. The figure illustrates the example including steps S802 and S804.

[0166] S802: The network-side device sends a second DCI to the terminal on the first serving cell. The second DCI includes a first indication field, which includes multi-bit information and selects a target bit to indicate whether the terminal should skip the first interval and / or restriction time corresponding to the target cell corresponding to the target bit.

[0167] In this multi-bit information, each bit corresponds one-to-one with a number of cells that can be scheduled by the second DCI. That is, the number of bits in the multi-bit information is the same as the maximum number of cells that can be scheduled by the second DCI, such as the number of scheduled cells indicated by the Scheduled cells indicator field. The target bit in the first indicator field can be one or more bits from the multi-bit information. When the target bit in the first indicator field is multiple bits, each bit can correspond to a scheduled cell, such as the bits in the multi-bit information corresponding sequentially to the scheduled cells in ascending cell index order.

[0168] It is worth mentioning that when multiple scheduled cells correspond to the same gap / restriction occasion configuration, the UE expects the bit values ​​corresponding to the scheduled cells with the same gap / restriction occasion configuration to be the same, such as both being 1 or both being 0. Therefore, the network-side device can make corresponding DCI indications based on this rule.

[0169] In this embodiment of the application, the target cell can be multiple cells in the intra-band or multiple cells in the inter-band, etc., and is not specifically limited.

[0170] The above steps, by selecting one or more target bits, can be used to provide instructions for some or all cells in the second DCI schedulable cells, which is a relatively flexible approach.

[0171] S804: The network-side device sends a second DCI to the terminal on the first serving cell. The second DCI includes a first indication field, which includes multi-bit information and selects a target bit to indicate whether the terminal should skip the first interval and / or restriction timing corresponding to the serving cell within the frequency range corresponding to the target bit.

[0172] In this context, each bit in the multi-bit information corresponds one-to-one with one of the multiple frequency ranges schedulable by the second DCI; that is, the number of bits in the multi-bit information is the same as the maximum number of frequency ranges schedulable by the second DCI. The target bit in the first indication field can be one or more bits from the multi-bit information.

[0173] The above steps, by selecting one or more target bits, can be used to indicate a portion or the entire frequency range within the schedulable frequency range of the second DCI, making the method quite flexible.

[0174] In one implementation, the target bit may include multiple bits in multi-bit information, and the target bit corresponds to multiple frequency ranges. The first indication field may select the target bit to indicate whether the terminal skips the first interval or restriction opportunity after the end position of the serving cell in each of the multiple frequency ranges corresponding to the target bit and the start position is not less than a preset time interval from the end position.

[0175] For example, when the UE is configured with a per FR measurement gap, the DCI 0_3 or 1_3 sent by the base station may contain a first indication field with 2 bits of information, which is used to indicate whether the UE skips the gap / restriction occasions corresponding to FR1 and FR2, respectively.

[0176] For example, when the DCI only schedules the UE to perform PUSCH or PDSCH transmissions on the serving cell of FR1 or FR2, and the UE expects the base station to only instruct the UE to skip the gap / restriction occasion corresponding to FR1 or FR2, the first indication field can include 2 bits of information, but selects a bit corresponding to FR1 or FR2 as the target bit to instruct the UE to skip the gap / restriction occasion corresponding to FR1 or FR2. In this case, the remaining bits other than the target bit, i.e., the bits corresponding to FR2 or FR1, can be either indicated as 0, reserved bits, or bits ignored by the UE.

[0177] Each of the aforementioned frequency ranges corresponds to its own preset time interval. In other words, the preset time interval for each frequency range can be determined independently. The preset time intervals for each frequency range can be the same or different; there is no specific limitation.

[0178] Figure 9 illustrates a schematic diagram of DCI using multi-bit information for indication provided in this embodiment of the application. Referring to Figure 9, the UE is configured with a per-FR measurement gap as an example. The DCI format on cell 0 can schedule cells 0, 1, and 2. The frequency ranges of cells 0, 1, and 2 include FR1 and FR2; the frequency domains of cells 0 and 1 belong to FR1, and the frequency domain of cell 2 belongs to FR2. Gap configuration 1 is the FR1 gap configuration, and gap configuration 2 is the FR2 gap configuration. The base station transmits a DCI 0_3 or 1_3 on cell 0, where the Scheduled cells indicator indicates that the DCI schedules PUSCH / PDSCH transmission on cells 0 and 2. This DCI 0_3 or 1_3 contains a 2-bit information field, corresponding to FR1 and FR2 respectively, used to indicate gap / restriction skipping.

[0179] In one implementation, the aforementioned multi-bit information can be applied to the scheduled cells indicated by the Scheduled cells indicator field. The number of bits in this multi-bit information is the number of scheduled cells, as shown in the figure (3). That is, the first indicator field includes 3 bits, corresponding to cells 0, 1, and 2 respectively, meaning there is a one-to-one correspondence between the bits and the cells. For example, if the value of the 3 bits is "110", it instructs the UE to skip the first gap / restriction occasion after the DCI ends for cells 0 and 1, provided the start position is at least a preset time interval T_offset1 from the end position, and not to skip the first gap / restriction occasion after the DCI ends for cell 2, provided the start position is at least a preset time interval T_offset2 from the end position. Optionally, considering that the gap / restriction occasions corresponding to cells 0 and 1 are the same, the base station should indicate the same value for the bits corresponding to cells 0 and 1, as shown in the figure (both are 1).

[0180] In another implementation, the aforementioned multi-bit information can be applied to multiple frequency ranges. The number of bits in this multi-bit information is the number of frequency ranges that the second DCI can schedule, as shown in the figure, which is two: FR1 and FR2. That is, the first indication field includes two bits, corresponding to cells in FR1 and FR2 respectively. For example, if the value of the two bits is "10", it instructs the UE to skip the first gap / restriction occasion after the DCI for the cell corresponding to FR1 ends, where the start position is at least a preset time interval T_offset1, and not to skip the first gap / restriction occasion after the DCI for the cell corresponding to FR2 ends, where the start position is at least a preset time interval T_offset2.

[0181] Figure 10 illustrates a schematic diagram of DCI indication under time-domain conflict provided in an embodiment of this application. Referring to Figure 10, the second serving cell has multiple intervals and / or restriction occasions of time-domain conflict. The first indication field in the second DCI may include 1 bit of information. In one implementation, the first indication field may indicate whether the terminal skips all first intervals and / or restriction occasions of the time-domain conflict corresponding to the second serving cell. As shown in Figure FR1, cell 0 has a time-domain conflict gap and a restriction occasion, which overlap in the time domain. The value of the 1 bit of information in the first indication field is 1, which is used to indicate that the terminal skips the time-domain conflict gap and restriction occasion. Specifically, it may indicate that the terminal skips the first time-domain conflict gap and restriction occasion after the DCI corresponding to cell 0 ends and the start position is not less than a preset time interval T_offset from the end position.

[0182] In another implementation, the first indication field can use 1 bit of information to indicate whether the terminal should skip the first interval and / or restriction opportunity after time-domain conflict resolution for the second serving cell. For example, if the time-domain conflict is a concurrent gap / restriction occasion, the UE first processes the gap / restriction occasion according to priority to determine the gap / restriction occasion after time-domain conflict resolution. Then, the first indication field uses 1 bit of information to indicate the gap / restriction occasion after time-domain conflict resolution.

[0183] In another implementation, the first indication field can use 1 bit of information to indicate whether the terminal should skip a certain gap / restriction occasion of a time-domain conflict corresponding to the second serving cell. If there are multiple gap / restriction occasions of time-domain conflict, the earliest gap / restriction occasion can be determined according to its starting position, indicating whether the terminal should skip the earliest starting gap / restriction occasion among the time-domain conflicts. The base station can use DCIs transmitted at different time positions to indicate whether the UE should skip multiple gap / restriction occasions of time-domain conflict.

[0184] In this embodiment of the application, the network-side device can also receive capability information reported by the terminal, which includes one of the following:

[0185] 1) The terminal supports the first mode;

[0186] 2) The terminal supports the second mode;

[0187] 3) The terminal supports a third mode;

[0188] 4) If the terminal supports both the first and second modes, the base station can be configured to use either the first or the second mode to instruct the UE.

[0189] 5) If the terminal supports both the second and third modes, the base station can be configured to use either the second or third mode to instruct the UE.

[0190] The first mode and the second mode both include: when the first indication field is a first value, it is used to instruct the terminal to skip the first interval and / or restriction time corresponding to the second serving cell; when the first indication field is a second value, it is used to instruct the terminal not to skip the first interval and / or restriction time corresponding to the second serving cell, or to instruct the terminal to maintain the same behavior as before within the first interval and / or restriction time corresponding to the second serving cell.

[0191] The first mode further includes: if the first indication field is a first value, then the first indication field in the DCI indicating the first interval and / or the DCI limiting the timing after the second DCI is also a first value.

[0192] The second mode further includes: if there are multiple second DCIs that indicate the first interval and / or the timing of the restriction through the first indication field, the terminal determines whether to skip the first interval and / or the timing of the restriction based on the last received second DCI.

[0193] The third mode includes: when the first indication field is a first value, it is used to instruct the terminal to skip the first interval and / or restriction timing corresponding to the second serving cell; when the first indication field is a second value, it represents reserved bit information or indication information that the terminal ignores the indication field.

[0194] Figure 11 illustrates a schematic diagram of DCI indication when the terminal supports different modes according to an embodiment of this application. Referring to Figure 11, the base station can adopt different DCI indications depending on the different modes supported by the terminal. In the first mode, a bit in the first indication field, when its value is 1, instructs the UE to skip the gap / restriction occasion corresponding to the second serving cell, and when its value is 0, instructs the UE not to skip the gap / restriction occasion corresponding to the second serving cell, that is, the UE's behavior within the gap / restriction occasion can remain the same as its previous behavior (as legacy).

[0195] In this scenario, when the UE receives a DCI with a first indication field value of 1, the UE does not expect the value of this bit to be different in DCIs indicating the same gap / restriction occasion; that is, it expects the bit to be 1 in all of them. Therefore, the base station uses a bit value of 1 in all DCIs indicating the same gap / restriction occasion. The diagram shows three DCIs indicating the same gap / restriction occasion. The first DCI uses a bit value of 0, the second DCI uses a bit value of 1, and the UE does not expect this bit to be 0 in subsequent DCIs indicating the same gap / restriction occasion. Therefore, the base station sets this bit to 1 in all DCIs indicating the same gap / restriction occasion after the second DCI, as shown in the third DCI in the diagram. In this method, once a gap / restriction occasion is indicated as skipped, the UE cannot be instructed not to skip that gap / restriction occasion again. This method is relatively simple for UE implementation.

[0196] In the second mode, if there are multiple DCIs indicating the first gap and / or restriction occasion, the terminal determines whether to skip the first gap and / or restriction occasion based on the last received DCI. In the diagram, the first DCI in the second mode uses a first indication field with a value of 1, and the second DCI uses a first indication field with a value of 0. Therefore, based on the indication of the later DCI, the UE determines not to skip the corresponding gap / restriction occasion, and the UE can maintain the same behavior as before, such as not needing to receive PDCCH / PDSCH / CSI-RS, or not needing to transmit PUCCH / PUSCH / SRS, etc.

[0197] In the second mode described above, there are no restrictions on the instructions given to the base station, and previous instructions to the UE can be changed at will, offering a certain degree of flexibility. However, the UE needs to wait until a certain gap / restriction occasion before it can indicate all possible DCIs for that gap / restriction occasion, and needs to find which is the later / latest DCI to determine whether to skip that gap / restriction occasion. Alternatively, the UE can also implement its own method, receiving a DCI and executing the corresponding instruction according to the corresponding instruction, without waiting for the last DCI, executing the instruction according to the latest received DCI each time. In this case, the UE implementation is more complex.

[0198] In this embodiment of the application, the terminal may determine the last received second DCI in any of the following ways:

[0199] 1) The method for determining the PUCCH resource for HARQ-ACK feedback in NR is the same; please refer to the relevant NR protocol for details.

[0200] 2) The method determines the order based on at least one of the following: sorting by PDCCH monitor occasion, sorting by serving cell index, sorting by CORESET pool index, and sorting by corresponding frequency. The sorting by monitor occasion can be from front to back, the sorting by index can be from smallest to largest, and the sorting by frequency can be from low frequency to high frequency, etc., without specific limitations.

[0201] In the third mode, a first indication field of 1 can be used to instruct the terminal to skip the first interval and / or restriction occasion corresponding to the second serving cell; a first indication field of 0 indicates reserved bit information or that the terminal ignores the indication information in that field. As shown in the figure, the first DCI in the third mode uses a bit with a value of 1, and the second DCI uses a bit with a value of 0. Therefore, when the UE receives the first DCI, where the first indication field uses a bit with a value of 1, the corresponding gap / restriction occasion will be skipped. When the UE receives the second DCI, where the first indication field uses a bit with a value of 0, the UE can ignore the indication. In this method, there are no restrictions on the base station's indication, but the base station's skip instruction cannot change the UE's behavior; however, the implementation on the UE side is relatively simple.

[0202] When a UE operates in dual-connectivity mode, such as EN-DC, NE-DC, or NR-DC, the serving cell configured for the UE may belong to different RATs (Radio Access Technologies), each with its own gap / restriction configuration. However, a RAT's own gap / restriction configuration may affect the UE's data transmission and reception on the serving cell of another RAT. For example, in existing NR specifications, during per-UE measurement intervals, besides receiving signals for RRM measurements and random access procedures as per relevant protocols, the UE does not need to receive / transmit E-UTRAN-NR dual connections to / from the corresponding E-UTRAN PCell, E-UTRAN cell, and NR serving cell. If each RAT might send its own DCI instructing the UE to skip a certain gap / restriction occasion, the other network will not know this information and therefore will not know that a certain gap / restriction occasion has been skipped. Consequently, it will not perform data scheduling during the corresponding gap / restriction occasion, thus reducing the system performance improvement brought about by skipping gap / restriction occasions. To address this issue and improve resource utilization more effectively in the corresponding scenarios, at least one of the following methods can be adopted:

[0203] Method 1. When the UE is configured for dual-link, use higher-layer signaling, such as RRC or MAC CE, to instruct the UE to skip one or more gap / restriction occasions.

[0204] Method 2. When the UE is configured with dual-link, the base station cannot configure the UE to perform gap / restriction skipping.

[0205] Method 3, the method of dynamically instructing the UE to skip gap / restriction occasions (DCI indication method), is only applicable when the UE is not configured for dual-linkage. Alternatively, when the UE is configured for dual-linkage, the UE does not expect to be configured to skip gap / restriction occasions via dynamic indication (DCI indication method).

[0206] Method 4. Base station / RAT exchange gap / restriction configuration information and / or gap / restriction occasion skipping information. For example, base station / RAT exchange gap / restriction configuration information. Optionally, the base station exchanges information on gap / restriction occasion skipping (which may be at least one skipped / non-skipped, consecutive / non-consecutive gap / restriction occasions) to the other base station for a period of time.

[0207] Method 5. Optionally, methods 1, 3, and 4 above are applicable to the MR-DC case.

[0208] Method 6. Optionally, methods 1, 3, and 4 above are applicable when MCG and SCG use different frequency domain ranges.

[0209] Method 7. Optionally, Method 2 above is applicable to EN-DC and / or NE-DC cases.
