Description

Technical Field

[0001] The present disclosure relates to the field of communication technologies, and in particular, to an activation indication method, an activation determination method, an activation indication device, an activation determination device, an electronic device, and a computer-readable storage medium. Background Art

[0002] Through Carrier Aggregation (CA) technology, multiple Component Carriers (CCs) can be aggregated for use, thus effectively increasing the system bandwidth and network capacity, and providing effective support for high-rate data transmission. Currently, up to 16 CCs can be aggregated. In the CA scenario, a terminal can simultaneously transmit and receive data on multiple CCs.

[0003] In 5G NR (New Radio), a CC can also be referred to as a cell. The Dual Connectivity (DC) technology is introduced in 5G NR. Based on the DC technology, a terminal can maintain connections with two base stations. One of the two base stations with which the terminal maintains connections is the master station, and the other is the secondary station. All CCs belonging to the master station form a group (abbreviated as MCG), and all CCs belonging to the secondary station form a group (abbreviated as SCG). In the CA / DC scenario, the anchor carrier corresponding to the MCG is called the PCell (Primary Cell), the anchor carrier corresponding to the SCG is called the PSCell (Primary Secondary Cell), and other carriers are called SCell (Secondary Cell).

[0004] In the CA / DC scenario, since the radio links of multiple carriers are maintained simultaneously, the power consumption of the terminal and the network is a problem. In the CA / DC scenario, generally, the primary cell provides coverage, and the secondary cell provides capacity. When parameters such as the data rate of the terminal change dynamically, the network capacity can be changed by activating / deactivating the secondary cell, thereby adjusting the power consumption of the terminal and the network.

[0005] In the related art, the terminal is instructed to activate / deactivate the SCell through high-layer signaling (such as the Medium Access Control layer Control Element MAC CE). Since the high-layer signaling is above the physical layer and requires more processing procedures, there is a relatively large delay when instructing the terminal, which is not conducive to the efficient use of radio resources and the energy saving of the terminal. Summary of the Invention

[0047] Next, the technical solutions in the embodiments of the present disclosure will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present disclosure.

[0048] Figure 1It is a schematic flowchart of an activation indication method shown according to an embodiment of the present disclosure. The activation indication method shown in this embodiment can be applied to a base station, and the base station includes but is not limited to 4G base stations, 5G base stations, and 6G base stations. The base station can communicate with a terminal serving as a user equipment, and the terminal includes but is not limited to electronic devices such as mobile phones, tablet computers, wearable devices, sensors, and Internet of Things devices. In one embodiment, the terminal can be the terminal applicable to the activation determination method described in any subsequent embodiment.

[0049] As Figure 1 shown, the activation indication method may include the following steps:

[0050] In step S101, send downlink control information DCI (Downlink Control Information) to the terminal, where the DCI is used to indicate the terminal to activate and / or deactivate a secondary cell SCell.

[0051] In one embodiment, different from the related art, the present disclosure can indicate to the terminal to activate the SCell through the DCI, and can also indicate to the terminal to deactivate the SCell through the DCI, and the indicated SCell can be determined by the base station or by the terminal.

[0052] Since the DCI is generally located in the physical downlink control channel PDCCH (Physical Downlink Control CHannel), it belongs to physical layer information. The process of the base station sending physical layer information is relatively simple compared to the process of the base station sending high-layer signaling such as MAC CE, so it can be quickly indicated to the terminal, reducing the delay of indicating the terminal to activate and / or deactivate the SCell, so that the terminal can activate and / or deactivate the indicated SCell as soon as possible according to the DCI, which is beneficial to the efficient utilization of radio resources and the energy saving of the terminal.

[0053] The embodiments of the present disclosure can use the DCI to indicate the terminal to activate and / or deactivate the SCell. However, since the format and the indicated information of the existing DCI in the related art have been determined, in order to achieve a functional distinction from the existing DCI, the following several implementation manners are provided for exemplary description.

[0054] Optionally, the format of the DCI used to indicate the terminal to activate and / or deactivate the SCell is different from the format of the DCI used to indicate other information.

[0055] In one embodiment, for the DCI used to indicate the activation and / or deactivation of SCell by the terminal, it can be generated by adding a new field to the existing DCI format. For example, a new field can be added to DCI format 1_0, DCI format 1_1, and DCI format 2_0; alternatively, a separate DCI different from the existing DCI formats in the related art can be used to indicate the activation and / or deactivation of SCell by the terminal.

[0056] Optionally, the radio network temporary identity RNTI corresponding to the DCI used to indicate the activation and / or deactivation of SCell by the terminal (this DCI can be specifically used to indicate the activation and / or deactivation of SCell by the terminal) is different from the RNTI corresponding to the DCI used to indicate other information.

[0057] In one embodiment, for the DCI used to indicate the activation and / or deactivation of SCell by the terminal, it can be set that the RNTI corresponding to this DCI is different from the RNTI corresponding to the DCI used to indicate other information.

[0058] Among them, the RNTI can be used by the terminal to obtain the DCI from the PDCCH. For example, the RNTI (such as RNTI1) configured for the DCI indicating the activation and / or deactivation of SCell by the terminal is different from the RNTIs (such as RNTI2, RNTI3, RNTI4, etc.) configured for the DCI indicating other information. Then, the DCI obtained by the terminal from the PDCCH based on RNTI1 can activate and / or deactivate SCell.

[0059] Optionally, the DCI at least includes a first field and a second field. Among them, the first field is used to indicate the activation and / or deactivation of SCell by the terminal, and the second field is used to indicate other information.

[0060] In one embodiment, the existing DCI in the related art can be reused. However, the meanings of the existing fields in the existing DCI in the related art have been determined. The present disclosure can add a field, such as called the first field, to the DCI to be used to indicate the activation and / or deactivation of SCell by the terminal. Then, the original fields in the DCI, such as called the second field, can continue to be used to indicate other information, so as to reuse the DCI without affecting the original functions of the DCI.

[0061] In one embodiment, the first field may include the first target field in the subsequent embodiments, or may include the second target field in the subsequent embodiments. For example, the first field is the first target field, or the first field is the second target field.

[0062] Figure 2It is a schematic flowchart of another activation indication method shown according to an embodiment of the present disclosure. As Figure 2 shown, the method further includes:

[0063] In step S201, group the SCell available to the terminal to obtain grouping information;

[0064] In step S202, send the grouping information to the terminal.

[0065] In one embodiment, since the number of SCell available to the terminal can be relatively large, but the number of bits in the DCI is limited, it may be difficult to perform targeted indication for each SCell. Therefore, the present disclosure can first group the SCell available to the terminal so as to perform indication for the grouped SCell groups. In addition, the grouping information obtained by grouping can also be sent to the terminal so that the terminal can determine the specific indication situation of the DCI based on the grouping information.

[0066] In one embodiment, the number of SCell available to the terminal can be determined first. The SCell available to the terminal are grouped only when the number of SCell available to the terminal is greater than a preset number, and when the number of SCell available to the terminal is less than the preset number, it is not necessary to group the SCell available to the terminal.

[0067] Optionally, the grouping information includes at least one of the following:

[0068] The SCell in each SCell group, the number of groups for grouping the SCell.

[0069] It should be noted that the grouping information is not limited to the above information. For example, it may also include the number of SCell in each SCell group, the association relationship between each SCell group and the bits in the DCI, etc.

[0070] Optionally, the DCI includes a first target field, the number of bits of the first target field is equal to the number of groups, and the first target field is used to indicate to activate the SCell in the first target group among the grouped SCell and / or deactivate the SCell in the second target group among the grouped SCell.

[0071] In one embodiment, the DCI may include a first target field. Herein, the first target field may be all fields of the DCI or partial fields in the DCI. The number of bits of the first target field is equal to the number of groups. Then, it may be indicated by the first target field to activate the SCell in the first target group among the grouped SCell, or it may also be indicated by the first target field to deactivate the SCell in the second target group among the grouped SCell. Herein, the first target group may be one SCell group or multiple SCell groups (for example, it may be all SCell groups after grouping or partial SCell groups), and the second target group may be one SCell group or multiple SCell groups (for example, it may be all SCell groups after grouping or partial SCell groups).

[0072] For example, there are 31 available SCell for the terminal, numbered from 0 to 30. The SCell are grouped into 4 SCell groups. The first SCell group contains 8 SCell, namely SCell0 to SCell7. The second SCell group contains 8 SCell, namely SCell8 to SCell15. The third SCell group contains 8 SCell, namely SCell16 to SCell23. The fourth SCell group contains 7 SCell, namely SCell24 to SCell30.

[0073] The first target field in the DCI includes 4 bits. For example, the first bit is associated with the first SCell group, the second bit is associated with the second SCell group, the third bit is associated with the third SCell group, and the fourth bit is associated with the fourth SCell group. A bit value of 0 indicates deactivation, and a bit value of 1 indicates activation.

[0074] For example, when the first target field in the DCI is 0101, the DCI may indicate the terminal to deactivate the SCell in the first SCell group and the third SCell group, and activate the SCell in the second SCell group and the fourth SCell group. For example, when the first target field in the DCI is 1111, the DCI may indicate the terminal to activate the SCell in 4 SCell groups.

[0075] If each SCell is indicated by one bit respectively, 31 bits are required. However, in this embodiment, the terminal can be indicated to activate and / or deactivate 31 SCell through a 4-bit field, thus effectively reducing the number of bits occupied by the DCI and being beneficial to saving communication resources.

[0076] Optionally, the DCI includes a second target field. The number of bits of the second target field is 1, and the number of groups for SCell grouping is 2;

[0077] The second target field is used to indicate activating the SCell in the first SCell group and deactivating the SCell in the second SCell group.

[0078] Or

[0079] The second target field is used to indicate deactivating the SCell in the first SCell group and activating the SCell in the second SCell group.

[0080] In one embodiment, the DCI may include a second target field. The second target field may be all fields of the DCI or partial fields of the DCI. The number of bits of the second target field is 1, and the number of groups of SCell grouping is 2. The base station and the terminal may pre-agree that for the SCell divided into two groups, the two SCell groups may include two cases: one case is that the SCell in the first SCell group is activated and the SCell in the second SCell group is deactivated; the other case is that the SCell in the first SCell group is deactivated and the SCell in the second SCell group is activated. Then these two cases can be represented by one bit.

[0081] For example, the available SCell of the terminal is 31, numbered from 0 to 30. The SCell is grouped into 2 SCell groups. The first SCell group contains 16 SCell, which are SCell0 to SCell15, and the second SCell group contains 16 SCell, which are SCell18 to SCell30.

[0082] For example, when the second target field in the DCI is 1, the DCI may indicate that the terminal activates 16 SCell in the first SCell group and deactivates 15 SCell in the second SCell group. For example, when the second target field in the DCI is 0, the DCI may indicate that the terminal deactivates 16 SCell in the first SCell group and activates 15 SCell in the second SCell group.

[0083] If each SCell is indicated by one bit respectively, 31 bits are required. However, in this embodiment, the terminal can be indicated to activate and / or deactivate 31 SCell through a 1-bit field, thereby effectively reducing the number of bits occupied by the DCI and being beneficial to saving communication resources.

[0084] Figure 3FIG. 0 is a schematic flowchart of an activation determination method shown according to an embodiment of the present disclosure. The activation determination method shown in this embodiment can be applied to a terminal, and the terminal includes, but is not limited to, electronic devices such as mobile phones, tablet computers, wearable devices, sensors, and Internet of Things devices. The terminal can communicate with a base station as a user equipment, and the base station includes, but is not limited to, 4G base stations, 5G base stations, and 6G base stations. In one embodiment, the base station can be the base station applicable to the activation indication method described in any of the above embodiments.

[0085] As Figure 3 shown, the activation determination method may include the following steps:

[0086] In step S301, receive downlink control information DCI sent by the base station;

[0087] In step S302, activate and / or deactivate a secondary cell SCell according to the DCI.

[0088] Since DCI is generally located in the physical downlink control channel PDCCH, it belongs to physical layer information. The process of the base station sending physical layer information is relatively simple compared to the process of the base station sending high-layer signaling such as MAC CE. Therefore, it can be quickly indicated to the terminal, reducing the delay of indicating the terminal to activate and / or deactivate the SCell, so that the terminal can activate and / or deactivate the indicated SCell as soon as possible according to the DCI, which is beneficial to the efficient utilization of radio resources and the energy saving of the terminal.

[0089] Figure 4 FIG. 18 is a schematic flowchart of another activation determination method shown according to an embodiment of the present disclosure. As Figure 4 shown, the method further includes:

[0090] In step S401, determine that the DCI is used to indicate the terminal to activate and / or deactivate the SCell according to the format of the DCI.

[0091] In one embodiment, for the DCI used to indicate the terminal to activate and / or deactivate the SCell, it can be generated by adding a new field to the existing DCI format. For example, a new field is added to DCI format 1_0, DCI format 1_1, and DCI format 2_0; or a separate DCI different from the existing DCI format in the related art is used to indicate the terminal to activate and / or deactivate the SCell.

[0092] Accordingly, the terminal can determine, according to the format of the DCI, that the DCI is used to indicate the activation and / or deactivation of the SCell by the terminal. For example, it is determined that a DCI different from the above DCI format 1_0, DCI format 1_1, DCI format 2_0, etc. is used to indicate the activation and / or deactivation of the SCell by the terminal.

[0093] Figure 5 FIG. 4 is a schematic flowchart of another activation determination method shown according to an embodiment of the present disclosure. As Figure 5 shown, the method further includes:

[0094] In step S501, according to the radio network temporary identity RNTI corresponding to the DCI (the DCI can be specifically used to indicate the activation and / or deactivation of the SCell by the terminal), it is determined that the DCI is used to indicate the activation and / or deactivation of the SCell by the terminal.

[0095] In one embodiment, for the DCI used to indicate the activation and / or deactivation of the SCell by the terminal, the RNTI corresponding to the DCI can be set to be different from the RNTI corresponding to the DCI used to indicate other information.

[0096] Among them, the RNTI can be used by the terminal to obtain the DCI from the PDCCH. For example, the RNTI (for example, RNTI1) configured for the DCI indicating the activation and / or deactivation of the SCell by the terminal is different from the RNTI (for example, RNTI2, RNTI3, RNTI4, etc.) configured for the DCI indicating other information. Then, the DCI obtained by the terminal from the PDCCH based on RNTI1 can activate and / or deactivate the SCell.

[0097] Figure 6 FIG. 5 is a schematic flowchart of another activation determination method shown according to an embodiment of the present disclosure. As Figure 6 shown, activating and / or deactivating the SCell according to the DCI includes:

[0098] In step S601, in response to sending a hybrid automatic repeat request acknowledgment HARQ-ACK corresponding to the DCI to the base station, the SCell is activated and / or deactivated according to the DCI.

[0099] In one embodiment, in the case where there is no multiplexing of the existing DCI in the related art, when the terminal determines that it has correctly received the DCI, the terminal can send the HARQ-ACK corresponding to the DCI to the base station. In this case, the terminal can determine that the content indicated in the DCI has been successfully obtained, and then the SCell can be activated and / or deactivated according to the DCI.

[0100] It should be noted that before it is determined that the content indicated in the DCI has been successfully obtained, the terminal still follows the active and inactive states of the SCell in the case where the DCI is not received.

[0101] Figure 7 It is a schematic flowchart of another activation determination method shown according to an embodiment of the present disclosure. As Figure 7 shown, activating and / or deactivating the SCell according to the DCI includes:

[0102] In step S701, a first field is determined in the DCI, where the first field is used to indicate that the terminal activates and / or deactivates the SCell, and the DCI further includes a second field for indicating other information;

[0103] In step S702, the SCell is activated and / or deactivated according to the first field.

[0104] In one embodiment, the existing DCI in the related art can be reused, but the meaning of the existing fields in the existing DCI in the related art has been determined. The present disclosure can add a field in the DCI, for example, called the first field, to be used to indicate that the terminal activates and / or deactivates the SCell. Then, the existing fields in the DCI, for example, called the second field, can continue to be used to indicate other information.

[0105] The terminal can activate and / or deactivate the SCell according to the first field, and still can determine the other information indicated by the second field based on the second field, so as to reuse the DCI without affecting the original function of the DCI.

[0106] The terminal can activate and / or deactivate the SCell according to the first field, and still can determine the other information indicated by the second field based on the second field, so as to reuse the DCI without affecting the original function of the DCI.

[0107] In one embodiment, the first field may include the first target field in the subsequent embodiment, or may include the second target field in the subsequent embodiment. For example, the first field is the first target field, or the first field is the second target field.

[0108] Figure 8 It is a schematic flowchart of another activation determination method shown according to an embodiment of the present disclosure. As Figure 8 shown, activating and / or deactivating the SCell according to the DCI includes:

[0109] In step S801, in response to the physical uplink shared channel PUSCH scheduled by the DCI being sent, or in response to the HARQ-ACK corresponding to the physical downlink shared channel PDSCH scheduled by the DCI being sent, the SCell is activated and / or deactivated according to the DCI.

[0110] In one embodiment, in the case of reusing the existing DCI in related technologies, the terminal can operate based on the channels scheduled by the DCI.

[0111] For example, if the DCI is used to schedule the PUSCH, when the PUSCH scheduled by the DCI is sent, it can be determined that the content indicated in the DCI has been successfully obtained, and then the SCell can be activated and / or deactivated according to the DCI.

[0112] For example, if the DCI is used to schedule the PDSCH, if the PDSCH scheduled by the DCI is correctly received, the HAQR-ACK corresponding to the PDSCH can be sent to the base station, and when the HAQR-ACK corresponding to the PDSCH is sent, it can be determined that the content indicated in the DCI has been successfully obtained, and then the SCell can be activated and / or deactivated according to the DCI.

[0113] It should be noted that before it is determined that the content indicated in the DCI has been successfully obtained, the terminal still follows the activation and deactivation states of the SCell in the case where the DCI has not been received.

[0114] Figure 9 It is a schematic flowchart of another activation determination method shown according to an embodiment of the present disclosure. As Figure 9 shown, the method further includes:

[0115] In step S901, receive the grouping information obtained by grouping the SCell available to the terminal sent by the base station.

[0116] Optionally, the grouping information includes at least one of the following:

[0117] The SCell in each SCell group, the number of groups for grouping the SCell.

[0118] Figure 10 It is a schematic flowchart of another activation determination method shown according to an embodiment of the present disclosure. As Figure 10 shown, the DCI includes a first target field, the number of bits of the first target field is equal to the number of groups, and the activating and / or deactivating the SCell according to the DCI includes:

[0119] In step S1001, according to the grouping information and the first target field, activate the first target group among the grouped SCell and the SCell in the first target group, and / or deactivate the second target group among the grouped SCell and the SCell in the second target group.

[0120] In one embodiment, the DCI may include a first target field. Herein, the first target field may be all fields of the DCI or some fields in the DCI. The number of bits of the first target field is equal to the number of groups. Then, it can be indicated by the first target field to activate the SCell in the first target group among the grouped SCell, or it can also be indicated by the first target field to deactivate the SCell in the second target group among the grouped SCell. Herein, the first target group may be one SCell group or multiple SCell groups (for example, it may be all SCell groups after grouping or some SCell groups), and the second target group may be one SCell group or multiple SCell groups (for example, it may be all SCell groups after grouping or some SCell groups).

[0121] For example, there are 31 available SCell for the terminal, numbered from 0 to 30. The SCell are grouped into 4 SCell groups. The first SCell group contains 8 SCell, namely SCell0 to SCell7. The second SCell group contains 8 SCell, namely SCell8 to SCell15. The third SCell group contains 8 SCell, namely SCell16 to SCell23. The fourth SCell group contains 7 SCell, namely SCell24 to SCell30.

[0122] The first target field in the DCI includes 4 bits. For example, the first bit is associated with the first SCell group, the second bit is associated with the second SCell group, the third bit is associated with the third SCell group, and the fourth bit is associated with the fourth SCell group. A bit value of 0 indicates deactivation, and a bit value of 1 indicates activation.

[0123] For example, when the first target field in the DCI is 0101, the DCI may indicate the terminal to deactivate the SCell in the first SCell group and the third SCell group, and activate the SCell in the second SCell group and the fourth SCell group. For example, when the first target field in the DCI is 1111, the DCI may indicate the terminal to activate the SCell in the 4 SCell groups.

[0124] If each SCell is indicated by one bit respectively, 31 bits are required. However, in this embodiment, the terminal can be indicated to activate and / or deactivate 31 SCell by a 4-bit field, thus effectively reducing the number of bits occupied by the DCI and being beneficial to saving communication resources.

[0125] Optionally, the DCI includes a second target field, the number of bits of the second target field is 1, and the number of groups of SCell grouping is 2. Activating and / or deactivating the SCell according to the DCI includes:

[0126] Activating the SCell in the first SCell group and deactivating the SCell in the second SCell group according to the second target field,

[0127] Or

[0128] Deactivating the SCell in the first SCell group and activating the SCell in the second SCell group according to the second target field.

[0129] In one embodiment, the DCI may include a second target field. Among them, the second target field may be all fields of the DCI or part of the fields in the DCI. The number of bits of the second target field is 1, and the number of groups of SCell grouping is 2. The base station and the terminal may pre-agree that for the SCell divided into two groups, the two SCell groups may include two cases: one case is that the SCell in the first SCell group is activated and the SCell in the second SCell group is deactivated; another case is that the SCell in the first SCell group is deactivated and the SCell in the second SCell group is activated. Then these two cases can be represented by one bit.

[0130] For example, the available SCell of the terminal is 31, and the serial numbers are from 0 to 30. The SCell is grouped into 2 SCell groups. The first SCell group contains 16 SCell, which are SCell0 to SCell15, and the second SCell group contains 16 SCell, which are SCell18 to SCell130.

[0131] For example, when the second target field in the DCI is 1, the DCI may instruct the terminal to activate 16 SCell in the first SCell group and deactivate 15 SCell in the second SCell group. For example, when the second target field in the DCI is 0, the DCI may instruct the terminal to deactivate 16 SCell in the first SCell group and activate 15 SCell in the second SCell group.

[0132] If each SCell is indicated by one bit respectively, 31 bits are required. However, in this embodiment, a 1-bit field can be used to indicate the terminal to activate and / or deactivate 31 SCell, thereby effectively reducing the number of bits occupied by the DCI and being beneficial to saving communication resources.
