Abstract
Description
[0001] Divisional Application Instructions
[0002] This application is a divisional application based on the Chinese patent invention application with application number 202080002735.1, application date October 19, 2020, and invention name "Activation indication method and device, activation determination method and device". Technical Field
[0003] 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
[0004] Carrier aggregation (CA) technology allows multiple component carriers (CCs) to be aggregated for use, effectively increasing system bandwidth and network capacity, providing effective support for high-speed data transmission. Currently, up to 16 CCs can be aggregated. In CA, a terminal can simultaneously send and receive data on multiple CCs.
[0005] In 5G NR (New Radio), a CC can also be called a cell. 5G NR introduces dual connectivity (DC) technology. Based on dual connectivity technology, a terminal can maintain a connection with two base stations, one of which is a primary station and the other is a secondary station. All CCs belonging to the primary station form a group (MCG for short), and all CCs belonging to the secondary station form a group (SCG for short). 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 and secondary cells), and other carriers are called SCells (secondary cells).
[0006] In CA / DC scenarios, maintaining radio links across multiple carriers simultaneously raises concerns about power consumption in both terminals and the network. In CA / DC scenarios, primary cells typically provide coverage, while secondary cells provide capacity. When parameters such as terminal data rates change dynamically, network capacity can be adjusted by activating / deactivating secondary cells, thereby adjusting terminal and network power consumption.
[0007] In related technologies, high-level signaling (such as the media access control layer control element MAC CE) is used to instruct the terminal to activate / deactivate the SCell. Since high-level signaling is above the physical layer and requires more processing procedures, there is a large delay when instructing the terminal, which is not conducive to the efficient use of wireless resources and energy saving of the terminal. Summary of the Invention
[0008] In view of this, embodiments of the present disclosure propose 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 to solve technical problems in related technologies.

[0016] According to an eighth aspect of an embodiment of the present disclosure, a computer-readable storage medium is provided, on which a computer program is stored. When the program is executed by a processor, the steps in the above-mentioned activation determination method are implemented.
[0017] According to the embodiments of the present disclosure, since DCI is generally located in the physical downlink control channel PDCCH, it belongs to physical layer information.

[0037] The following will be combined with the accompanying drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the embodiments described are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present disclosure.
[0038] Figure 1 This is a schematic flow chart illustrating an activation indication method according to an embodiment of the present disclosure. The activation indication method illustrated in this embodiment can be applied to base stations, including but 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 device, including but not limited to electronic devices such as mobile phones, tablets, wearable devices, sensors, and IoT devices. In one embodiment, the terminal can be a terminal to which the activation determination method described in any subsequent embodiment is applicable.
[0039] like Figure 1As shown, the activation indication method may include the following steps:
[0040] In step S101, downlink control information DCI (Downlink Control Information) is sent to a terminal, wherein the DCI is used to instruct the terminal to activate and / or deactivate a secondary cell (SCell).
[0041] In one embodiment, different from the related art, the present disclosure can instruct the terminal to activate SCell through DCI, and can also instruct the terminal to deactivate SCell through DCI, and the indicated SCell can be determined by the base station or the terminal.
[0042] Since 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-level signaling such as MAC CE. Therefore, it can be quickly indicated to the terminal, reducing the delay of instructing 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 wireless resources and energy saving of the terminal.
[0043] The embodiments of the present disclosure can instruct the terminal to activate and / or deactivate SCell through DCI, but since the format and indicated information of the existing DCI in the related technology have been determined, in order to achieve functional distinction from the existing DCI, the following several implementation methods are provided for exemplary description.
[0044] Optionally, the format of the DCI used to instruct the terminal to activate and / or deactivate the SCell is different from the format of the DCI used to indicate other information.
[0045] In one embodiment, the DCI used to instruct the terminal to activate and / or deactivate the SCell can be generated by adding a new field to the existing DCI format, for example, adding a new field to DCI format 1_0, DCI format 1_1, DCIformat2_0; or using a separate DCI with a format different from the existing DCI in the related art to indicate the terminal to activate and / or deactivate the SCell.
[0046] Optionally, the radio network temporary identifier RNTI corresponding to the DCI used to indicate the terminal to activate and / or deactivate the SCell (the DCI may be specifically used to indicate the terminal to activate and / or deactivate the SCell) is different from the RNTI corresponding to the DCI used to indicate other information.
[0047] In one embodiment, for the DCI used to instruct the terminal to activate and / or deactivate the SCell, the RNTI corresponding to the DCI may be set to be different from the RNTI corresponding to the DCI used to indicate other information.
[0048] The RNTI can be used by the terminal to derive DCI from the PDCCH. For example, if the RNTI configured for the terminal for the DCI indicating activation and / or deactivation of the SCell (e.g., RNTI1) is different from the RNTI configured for the terminal for the DCI indicating other information (e.g., RNTI2, RNTI3, RNTI4, etc.), the terminal can activate and / or deactivate the SCell based on the DCI derived from the PDCCH based on RNTI1.
[0049] Optionally, the DCI includes at least a first field and a second field, wherein the first field is used to indicate that the terminal activates and / or deactivates the SCell, and the second field is used to indicate other information.
[0050] In one embodiment, the existing DCI in the related art can be reused, but the meanings of the existing fields in the existing DCI in the related art have been determined. The present disclosure can add a field in the DCI, for example, called the first field, to indicate that the terminal activates and / or deactivates the SCell. Then the original field in the DCI, for example, called the second field, can continue to be used to indicate other information, thereby multiplexing the DCI without affecting the original function of the DCI.
[0051] 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.
[0052] Figure 2 FIG is a schematic flow chart of another activation indication method according to an embodiment of the present disclosure. Figure 2 As shown, the method further includes:
[0053] In step S201, the SCells available to the terminal are grouped to obtain grouping information;
[0054] In step S202, the grouping information is sent to the terminal.
[0055] In one embodiment, since the number of SCells available to the terminal may be large, but the bits in the DCI are limited, it may be difficult to provide targeted indications for each SCell. Therefore, the present disclosure may first group the SCells available to the terminal so as to provide indications for the grouped SCell groups. In addition, the grouping information obtained by grouping may be sent to the terminal so that the terminal can determine the specific indication of the DCI based on the grouping information.
[0056] In one embodiment, the number of SCells available to the terminal can be determined first, and the SCells available to the terminal can be grouped only when the number of SCells available to the terminal is greater than a preset number. When the number of SCells available to the terminal is less than a preset number, the SCells available to the terminal do not need to be grouped.
[0057] Optionally, the grouping information includes at least one of the following:
[0058] SCells in each SCell group and the number of groups into which SCells are grouped.
[0059] It should be noted that the grouping information is not limited to the above information, and may also include, for example, the number of SCells in each SCell group, the association between each SCell group and the bits in the DCI, and the like.
[0060] 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 the SCell in the first target group in the SCell after activation grouping and / or the SCell in the second target group in the SCell after deactivation grouping.
[0061] In one embodiment, the DCI may include a first target field, wherein the first target field may be all fields of the DCI or part of the fields in the DCI, and the number of bits of the first target field is equal to the number of groups. Then, the first target field may be used to indicate activation of the SCells in the first target group in the grouped SCells, and the first target field may be used to indicate deactivation of the SCells in the second target group in the grouped SCells, wherein the first target group may be one SCell group or multiple SCell groups (for example, all grouped SCell groups or part of grouped SCell groups), and the second target group may be one SCell group or multiple SCell groups (for example, all grouped SCell groups or part of grouped SCell groups).
[0062] For example, the terminal has 31 available SCells, numbered 0 to 30. The SCells are grouped into four SCell groups. The first SCell group contains eight SCells, namely SCell0 to SCell7, the second SCell group contains eight SCells, namely SCell8 to SCell15, the third SCell group contains eight SCells, namely SCell16 to SCell23, and the fourth SCell group contains seven SCells, namely SCell24 to SCell30.
[0063] 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. Bit 0 indicates deactivation, and bit 1 indicates activation.
[0064] For example, when the first target field in the DCI is 0101, the DCI can instruct the terminal to deactivate the SCells in the first and third SCell groups, and activate the SCells in the second and fourth SCell groups. For example, when the first target field in the DCI is 1111, the DCI can instruct the terminal to activate the SCells in all four SCell groups.
[0065] If each SCell is indicated by one bit, 31 bits are required. However, this embodiment can use a 4-bit field to instruct the terminal to activate and / or deactivate 31 SCells, thereby effectively reducing the bits required for DCI and saving communication resources.
[0066] 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 grouping SCells is 2;
[0067] The second target field is used to indicate activation of the SCells in the first SCell group and deactivation of the SCells in the second SCell group, or the second target field is used to indicate deactivation of the SCells in the first SCell group and activation of the SCells in the second SCell group.
[0068] In one embodiment, the DCI may include a second target field, where the second target field may be all or part of the DCI field. The number of bits in the second target field is 1, and the number of SCell groupings is 2. The base station and the terminal may pre-agreed that for SCells divided into two groups, the two SCell groups may include two situations: one in which the SCells in the first SCell group are activated and the SCells in the second SCell group are deactivated; the other in which the SCells in the first SCell group are deactivated and the SCells in the second SCell group are activated. A single bit can represent both situations.
[0069] For example, the terminal has 31 available SCells, numbered 0 to 30. The SCells are grouped into two SCell groups. The first SCell group contains 16 SCells, SCell0 to SCell15, and the second SCell group contains 16 SCells, SCell18 to SCell130.
[0070] For example, if the second target field in the DCI is 1, the DCI can instruct the terminal to activate 16 SCells in the first SCell group and deactivate 15 SCells in the second SCell group. For example, if the second target field in the DCI is 0, the DCI can instruct the terminal to deactivate 16 SCells in the first SCell group and activate 15 SCells in the second SCell group.
[0071] If each SCell is indicated by one bit, 31 bits are required. However, this embodiment can use a 1-bit field to instruct the terminal to activate and / or deactivate 31 SCells, thereby effectively reducing the bits required for DCI and saving communication resources.
[0072] Figure 3 This is a schematic flow chart illustrating an activation determination method according to an embodiment of the present disclosure. The activation determination method illustrated in this embodiment can be applied to terminals, including but not limited to electronic devices such as mobile phones, tablets, wearable devices, sensors, and IoT devices. The terminal can communicate with a base station as a user equipment, including but not limited to a 4G base station, a 5G base station, and a 6G base station. In one embodiment, the base station can be a base station to which the activation indication method described in any of the above embodiments is applicable.
[0073] like Figure 3 As shown, the activation determination method may include the following steps:
[0074] In step S301, downlink control information DCI sent by a base station is received;
[0075] In step S302, the secondary cell (SCell) is activated and / or deactivated according to the DCI.
[0076] 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-level signaling such as MAC CE. Therefore, it can be quickly indicated to the terminal, reducing the delay of instructing 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 use of wireless resources and energy saving of the terminal.
[0077] Figure 4 FIG. 1 is a schematic flow chart of another activation determination method according to an embodiment of the present disclosure. Figure 4 As shown, the method further includes:
[0078] In step S401, according to the format of the DCI, it is determined that the DCI is used to instruct the terminal to activate and / or deactivate an SCell.
[0079] In one embodiment, the DCI used to instruct the terminal to activate and / or deactivate the SCell can be generated by adding a new field to the existing DCI format, for example, adding a new field to DCI format 1_0, DCI format 1_1, DCIformat2_0; or using a separate DCI with a format different from the existing DCI in the related art to indicate the terminal to activate and / or deactivate the SCell.
[0080] Accordingly, the terminal can determine, based on the format of the DCI, that the DCI is used to instruct the terminal to activate and / or deactivate the SCell, for example, determining that a DCII in a format different from the above-mentioned DCI format 1_0, DCI format 1_1, DCI format 2_0, etc. is used to instruct the terminal to activate and / or deactivate the SCell.
[0081] Figure 5 FIG. 1 is a schematic flow chart of another activation determination method according to an embodiment of the present disclosure. Figure 5 As shown, the method further includes:
[0082] In step S501, according to the radio network temporary identifier RNTI corresponding to the DCI (the DCI may be specifically used to instruct the terminal to activate and / or deactivate the SCell), it is determined that the DCI is used to instruct the terminal to activate and / or deactivate the SCell.
[0083] In one embodiment, for the DCI used to instruct the terminal to activate and / or deactivate the SCell, the RNTI corresponding to the DCI may be set to be different from the RNTI corresponding to the DCI used to indicate other information.
[0084] The RNTI can be used by the terminal to derive DCI from the PDCCH. For example, if the RNTI configured for the terminal for the DCI indicating activation and / or deactivation of the SCell (e.g., RNTI1) is different from the RNTI configured for the terminal for the DCI indicating other information (e.g., RNTI2, RNTI3, RNTI4, etc.), the terminal can activate and / or deactivate the SCell based on the DCI derived from the PDCCH based on RNTI1.
[0085] Figure 6 FIG. 1 is a schematic flow chart of another activation determination method according to an embodiment of the present disclosure. Figure 6 As shown, the activating and / or deactivating SCell according to the DCI includes:
[0086] In step S601, in response to sending a hybrid automatic repeat request acknowledgement HARQ-ACK corresponding to the DCI to the base station, an SCell is activated and / or deactivated according to the DCI.
[0087] In one embodiment, without reusing the existing DCI in the related technology, the terminal can send the HARQ-ACK corresponding to the DCI to the base station when it determines that the DCI is received correctly. In this case, the terminal can determine that the content indicated in the DCI has been successfully obtained, and then can activate and / or deactivate the SCell according to the DCI.
[0088] It should be noted that, before determining that the content indicated in the DCI has been successfully acquired, the terminal still uses the activation and inactivation states of the SCell when the DCI is not received.
[0089] Figure 7 FIG. 1 is a schematic flow chart of another activation determination method according to an embodiment of the present disclosure. Figure 7 As shown, the activating and / or deactivating SCell according to the DCI includes:
[0090] In step S701, a first field is determined in the DCI, where the first field is used to instruct the terminal to activate and / or deactivate an SCell, and the DCI further includes a second field for indicating other information;
[0091] In step S702, the SCell is activated and / or deactivated according to the first field.
[0092] In one embodiment, the existing DCI in the related technology can be reused, but the meanings of the existing fields in the existing DCI in the related technology have been determined. The present disclosure can add a field in the DCI, for example, called the first field, to indicate that the terminal activates and / or deactivates the SCell, then the original field in the DCI, for example, called the second field, can continue to be used to indicate other information.
[0093] The terminal can activate and / or deactivate the SCell based on the first field, and based on the second field, can still determine other information indicated by the second field, thereby multiplexing the DCI without affecting the original function of the DCI.
[0094] 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.
[0095] Figure 8 FIG. 1 is a schematic flow chart of another activation determination method according to an embodiment of the present disclosure. Figure 8 As shown, the activating and / or deactivating SCell according to the DCI includes:
[0096] In step S801, in response to the sending of the physical uplink shared channel PUSCH scheduled by the DCI, or in response to the sending of the HARQ-ACK corresponding to the physical downlink shared channel PDSCH scheduled by the DCI, the SCell is activated and / or deactivated according to the DCI.
[0097] In one embodiment, in the case of existing DCI in the reuse related technology, the terminal can operate based on the channel scheduled by the DCI.
[0098] For example, if DCI is used to schedule PUSCH, then when the PUSCH scheduled by DCI is sent, it can be determined that the content indicated in the DCI has been successfully acquired, and then the SCell can be activated and / or deactivated according to the DCI.
[0099] For example, DCI is used to schedule PDSCH. If the PDSCH scheduled by DCI is correctly received, the HAQR-ACK corresponding to the PDSCH can be sent to the base station. 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.
[0100] It should be noted that, before determining that the content indicated in the DCI has been successfully acquired, the terminal still uses the activation and inactivation states of the SCell when the DCI is not received.
[0101] Figure 9 FIG. 1 is a schematic flow chart of another activation determination method according to an embodiment of the present disclosure. Figure 9 As shown, the method further includes:
[0102] In step S901, grouping information obtained by grouping SCells available to the terminal and sent by the base station is received.
[0103] Optionally, the grouping information includes at least one of the following: SCells in each SCell group, and the number of groups into which the SCells are grouped.
[0104] Figure 10 FIG. 1 is a schematic flow chart of another activation determination method according to an embodiment of the present disclosure. Figure 10 As 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:
[0105] In step S1001, according to the grouping information and the first target field, the first target group in the grouped SCell and the SCell in the first target group are activated, and / or the second target group in the grouped SCell and the SCell in the second target group are deactivated.
[0106] In one embodiment, the DCI may include a first target field, wherein the first target field may be all fields of the DCI or part of the fields in the DCI, and the number of bits of the first target field is equal to the number of groups. Then, the first target field may be used to indicate activation of the SCells in the first target group in the grouped SCells, and the first target field may be used to indicate deactivation of the SCells in the second target group in the grouped SCells, wherein the first target group may be one SCell group or multiple SCell groups (for example, all grouped SCell groups or part of grouped SCell groups), and the second target group may be one SCell group or multiple SCell groups (for example, all grouped SCell groups or part of grouped SCell groups).
[0107] For example, the terminal has 31 available SCells, numbered 0 to 30. The SCells are grouped into four SCell groups. The first SCell group contains eight SCells, namely SCell0 to SCell7, the second SCell group contains eight SCells, namely SCell8 to SCell15, the third SCell group contains eight SCells, namely SCell16 to SCell23, and the fourth SCell group contains seven SCells, namely SCell24 to SCell30.
[0108] 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. Bit 0 indicates deactivation, and bit 1 indicates activation.
[0109] For example, when the first target field in the DCI is 0101, the DCI can instruct the terminal to deactivate the SCells in the first and third SCell groups, and activate the SCells in the second and fourth SCell groups. For example, when the first target field in the DCI is 1111, the DCI can instruct the terminal to activate SCell 1 in all four SCell groups.
[0110] If each SCell is indicated by one bit, 31 bits are required. However, this embodiment can use a 4-bit field to instruct the terminal to activate and / or deactivate 31 SCells, thereby effectively reducing the bits required for DCI and saving communication resources.
[0111] Optionally, the DCI includes a second target field, the number of bits of the second target field is 1, the number of groups for grouping SCells is 2, and activating and / or deactivating SCells according to the DCI includes:
[0112] The SCells in the first SCell group are activated according to the second target field, and the SCells in the second SCell group are deactivated, or the SCells in the first SCell group are deactivated according to the second target field, and the SCells in the second SCell group are activated.
[0113] In one embodiment, the DCI may include a second target field, where the second target field may be all or part of the DCI field. The number of bits in the second target field is 1, and the number of SCell groupings is 2. The base station and the terminal may pre-agreed that for SCells divided into two groups, the two SCell groups may include two situations: one in which the SCells in the first SCell group are activated and the SCells in the second SCell group are deactivated; the other in which the SCells in the first SCell group are deactivated and the SCells in the second SCell group are activated. A single bit can represent both situations.
[0114] For example, the terminal has 31 available SCells, numbered 0 to 30. The SCells are grouped into two SCell groups. The first SCell group contains 16 SCells, SCell0 to SCell15, and the second SCell group contains 16 SCells, SCell18 to SCell130.
[0115] For example, if the second target field in the DCI is 1, the DCI can instruct the terminal to activate 16 SCells in the first SCell group and deactivate 15 SCells in the second SCell group. For example, if the second target field in the DCI is 0, the DCI can instruct the terminal to deactivate 16 SCells in the first SCell group and activate 15 SCells in the second SCell group.
[0116] If each SCell is indicated by one bit, 31 bits are required. However, this embodiment can use a 1-bit field to instruct the terminal to activate and / or deactivate 31 SCells, thereby effectively reducing the bits required for DCI and saving communication resources.
