[0023] This disclosure provides a communication method, communication device, communication system, storage medium, and program product.

[0024] In a first aspect, embodiments of this disclosure propose a communication method executed by a first terminal. The method includes: receiving first information sent by a network device, the first information being used to instruct multiple terminals to perform secondary cell removal or secondary cell deactivation on a secondary cell corresponding to a first carrier, the multiple terminals including the first terminal, and the first carrier being a secondary carrier in carrier aggregation; and performing secondary cell removal or secondary cell deactivation on the secondary cell corresponding to the first carrier based on the first information.

[0025] In the above embodiments, the first terminal can receive first information sent by the network device. The first information is used to instruct multiple terminals to perform secondary cell removal or secondary cell deactivation on the secondary cell corresponding to the first carrier in carrier aggregation. The first terminal, as one of these multiple terminals, can perform secondary cell removal or secondary cell deactivation on the secondary cell corresponding to the first carrier based on the first information, so as to achieve the purpose of instructing multiple terminals to remove or deactivate the secondary cell through the first information, thereby reducing the signaling waste in instructing the secondary cell removal or deactivation process in carrier aggregation.

[0026] In conjunction with some embodiments of the first aspect, in some embodiments, the plurality of terminals belong to a terminal group, and the first information is obtained by scrambling a first identifier used to identify the terminal group; the step of removing or deactivating the secondary cell corresponding to the first carrier based on the first information includes: matching the first terminal group identifier of the first terminal with the first identifier used to scramble the first information, and removing or deactivating the secondary cell corresponding to the first carrier based on the first information.

[0027] In the above embodiments, by dividing terminal groups and using a first identifier to identify the terminal group to scramble the first information, it is ensured that only the first terminal whose first terminal group identifier matches the first identifier used to scramble the first information can parse the first information. This allows for secondary cell removal or deactivation of the secondary cell corresponding to the first carrier based on the first information. This ensures that while the first information can be used to indicate secondary cell removal or deactivation for multiple terminals in the terminal group identified by the first identifier, it also ensures that only specific terminals can perform secondary cell removal or deactivation based on the first information, thus guaranteeing the legality of the secondary cell removal or deactivation process.

[0028] In conjunction with some embodiments of the first aspect, in some embodiments, the method further includes: receiving the first terminal group identifier sent by the network device.

[0029] In the above embodiments, an optional implementation method for the terminal to obtain the first terminal group identifier is provided, that is, the network device configures the first terminal group identifier for the terminal, so as to ensure that the terminal can remove or deactivate the secondary cell based on the first information based on the first terminal group identifier configured for it by the network device.

[0030] In conjunction with some embodiments of the first aspect, in some embodiments, the first terminal group identifier and the identifier type of the first identifier are both Group Wireless Network Temporary Identifier (RNTI).

[0031] In the above embodiments, a first terminal group identifier and an optional identifier type of the first identifier are provided to ensure that the indication of the divided terminal group can be achieved through the group RNTI.

[0032] In conjunction with some embodiments of the first aspect, in some embodiments, receiving the first information sent by the network device includes any one of the following: receiving the first information sent by the network device on a secondary cell, wherein the first information is used to perform secondary cell removal or secondary cell deactivation on the secondary cell; receiving the first information sent by the network device on a first secondary cell or a primary cell, wherein the first information is used to perform secondary cell removal or secondary cell deactivation on a plurality of secondary cells, and the first secondary cell is at least one of the plurality of secondary cells.

[0033] In the above embodiments, an optional implementation method is provided to realize the interaction between the network device and the terminal based on the first information when the first information is used to remove or deactivate a secondary cell, and when the first information is used to remove or deactivate multiple secondary cells. That is, when the first information is used to remove or deactivate a secondary cell, the network device and the terminal can transmit and receive the first information on the secondary cell. When the first information is used to remove or deactivate multiple secondary cells, the network device and the terminal can transmit and receive the first information on the primary cell or the first secondary cell among the multiple secondary cells, thereby ensuring the legality of the transmission and reception process of the first information.

[0034] In conjunction with some embodiments of the first aspect, in some embodiments, the first information is obtained by scrambling a second identifier; the step of removing or deactivating a secondary cell corresponding to the first carrier based on the first information includes any one of the following: the second identifier is an identifier for paging messages, the device paging identifier configured by the network device for the first terminal matches the second identifier used to scramble the first information, and the secondary cell corresponding to the first carrier is removed or deactivated based on the first information; or the second identifier is an identifier for system information broadcasting, the system information identifier configured by the network device for the first terminal matches the second identifier used to scramble the first information, and the secondary cell corresponding to the first carrier is removed or deactivated based on the first information.

[0035] In the above embodiments, the first information is scrambled by using a second identifier for identifying paging messages or for identifying system information broadcasts. This ensures that only a first terminal whose device paging identifier matches the second identifier used to identify paging messages when scrambling the first information, or a second terminal whose system information identifier matches the second identifier used to identify system information broadcasts when scrambling the first information, can parse the first information. This allows for secondary cell removal or deactivation of the secondary cell corresponding to the first carrier based on the first information. While ensuring that secondary cell removal or deactivation instructions for multiple terminals whose device paging identifiers or system information identifiers meet the requirements can be implemented through the first information, it also ensures that only specific terminals can implement secondary cell removal or deactivation based on the first information, thus guaranteeing the legality of the secondary cell removal or deactivation process.

[0036] In conjunction with some embodiments of the first aspect, in some embodiments, the second identifier is an identifier for paging messages, the second identifier being a Paging Radio Network Temporary Identifier (P-RNTI); or, the second identifier is an identifier for system information broadcasting, the second identifier being a System Information Radio Network Temporary Identifier (SI-RNTI).

[0037] In the above embodiments, optional identifier types are provided for identifying a second identifier for paging messages and a second identifier for identifying system information broadcasts, so as to realize the reuse of P-RNTI and SI-RNTI and improve the utilization rate of P-RNTI and SI-RNTI.

[0038] In conjunction with some embodiments of the first aspect, in some embodiments, the plurality of terminals belong to multiple terminal groups, and the first information includes multiple third identifiers for identifying the plurality of terminal groups; the step of removing or deactivating the secondary cell corresponding to the first carrier based on the first information includes: the second terminal group identifier of the first terminal matches any of the third identifiers included in the first information, and removing or deactivating the secondary cell corresponding to the first carrier based on the first information.

[0039] In the above embodiments, by dividing terminal groups and carrying a third identifier for identifying terminal groups in the first information, it is ensured that only the first terminal whose second terminal group identifier matches the third identifier included in the first information can perform secondary cell removal or secondary cell deactivation on the secondary cell corresponding to the first carrier based on the first information. This ensures that while the first information can be used to indicate secondary cell removal or secondary cell deactivation for multiple terminals in the terminal group identified by the third identifier, it also ensures that only specific terminals can perform secondary cell removal or secondary cell deactivation based on the first information, thereby ensuring the legality of the secondary cell removal or deactivation process.

[0040] In conjunction with some embodiments of the first aspect, in some embodiments, the identifier type of both the second terminal group identifier and the third identifier is a group identifier ID.

[0041] In the above embodiments, an optional identifier type is provided for the second terminal group identifier and the third identifier to ensure that the division of the terminal group can be indicated by the group ID.

[0042] In conjunction with some embodiments of the first aspect, in some embodiments, the first information is used to perform secondary cell removal or secondary cell deactivation on one or more secondary cells, and the first information further includes index information of the one or more secondary cells.

[0043] In the above embodiments, the flexibility and versatility of the first information are improved by configuring the first information for performing secondary cell removal or secondary cell deactivation on one or more secondary cells. Furthermore, by carrying index information of one or more secondary cells in the first information, the terminal can determine these one or more secondary cells based on the index information included in the first information, thereby ensuring the smooth execution of the secondary cell removal or deactivation process for these one or more secondary cells.

[0044] In conjunction with some embodiments of the first aspect, in some embodiments, the first information is carried via the Physical Downlink Control Channel (PDCCH).

[0045] In the above embodiments, the first information is carried by PDCCH, thereby enabling the reuse of PDCCH and improving the utilization rate of PDCCH.

[0047] In the above embodiments, by providing a new cell state, namely, allowing the first terminal to retain the configuration of the secondary cell corresponding to the first carrier but not to perform the measurement of the secondary cell corresponding to the first carrier, the network device can configure this cell state for the terminal through the second information. The terminal can then receive the second information sent by the network device to configure the cell state of the secondary cell corresponding to the first carrier as the first state, thereby improving the flexibility and diversity of the cell state configuration process.

[0051] In the above embodiments, when the second information is used to indicate the cell status of the secondary cells corresponding to one or more groups of first carriers, the terminal can receive the third information sent by the network device by sending the third information to the terminal. The thirteenth information is used to indicate the carrier group to which each first carrier belongs. Based on the third information, the terminal can determine the carrier group to which each first carrier belongs. Thus, when the second information is used to indicate the cell status of the secondary cells corresponding to one or more groups of first carriers, the terminal can determine the cell status of the secondary cells corresponding to each first carrier based on the carrier group to which each first carrier belongs.

[0052] In conjunction with some embodiments of the first aspect, in some embodiments, the second information is used to indicate any one of the following: the duration of the cell state of a secondary cell corresponding to one or more first carriers, the duration of the cell state of a secondary cell corresponding to a first carrier in one or more frequency bands, or the duration of the cell state of a group or more groups of secondary cells corresponding to first carriers.

[0107] Figure 1 is a schematic diagram of the architecture of a communication system according to an embodiment of the present disclosure. As shown in Figure 1, the communication system 100 includes a terminal 101 and a network device 102.

[0113] In some embodiments, the access network device may be composed of a central unit (CU) and a distributed unit (DU). The CU may also be called a control unit. The CU-DU structure can separate the protocol layer of the access network device. Some of the protocol layer functions are centrally controlled by the CU, while the remaining part or all of the protocol layer functions are distributed in the DU and centrally controlled by the CU. However, this is not the only possibility.

[0114] In some embodiments, the core network equipment may include a first network element, such as an Access and Mobility Management Function (AMF).

[0127] In some embodiments, each of the above network elements may be part of the core network equipment.

[0128] It is understood that the communication system described in this disclosure is for the purpose of more clearly illustrating the technical solutions of this disclosure, and does not constitute a limitation on the technical solutions proposed in this disclosure. As those skilled in the art will know, with the evolution of system architecture and the emergence of new business scenarios, the technical solutions proposed in this disclosure are also applicable to similar technical problems.

[0129] The following embodiments of this disclosure can be applied to the communication system 100 shown in FIG1, or to some of the main bodies, but are not limited thereto. The main bodies shown in FIG1 are illustrative. The communication system may include all or some of the main bodies in FIG1, or may include other main bodies outside of FIG1. ​​The number and form of each main body are arbitrary. Each main body may be physical or virtual. The connection relationship between the main bodies is illustrative. The main bodies may not be connected or may be connected. The connection can be in any way, it can be a direct connection or an indirect connection, it can be a wired connection or a wireless connection.

[0130] The embodiments disclosed herein can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), Future Radio Access (FRA), New-Radio Access Technology (RAT), New Radio (NR), New radio access (NX), Future generation radio access (FX), Global System for Mobile communications (GSM), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), and IEEE 802.20, Ultra-Wideband (UWB), Bluetooth (a registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X) systems, systems utilizing other communication methods, and next-generation systems built upon them, etc. Furthermore, multiple systems can be combined (e.g., a combination of LTE or LTE-A with 5G).

[0131] In some embodiments, cells in carrier aggregation can be divided into primary cells (PCell), secondary cells (SCell), and serving cells.

[0132] In some embodiments, the primary cell can operate on the primary CC for the initial connection establishment and connection re-establishment processes.

[0133] In some embodiments, the secondary cell can operate on the secondary CC to provide additional radio resources after a Radio Resource Control (RRC) connection is established.

[0134] In some embodiments, for a terminal in RRC connected state (RRC_CONNECTED), if no CA is configured for it, it has only one Serving Cell (i.e., PCell). If a CA is configured, its Serving Cell set consists of PCell and SCell.

[0135] In some embodiments, SCells can be configured via RRC signaling (such as RRC reconfiguration messages). SCells can be activated or deactivated. For example, a base station can instruct a terminal to activate or deactivate one or more SCells via a Media Access Control (MAC) control element (CE).

[0136] In some embodiments, SCell removal or deactivation is indicated for a single terminal. Therefore, the base station can use dedicated RRC signaling or MAC CE to indicate SCell removal or deactivation. However, when carrier shutdown is introduced into network power-saving features, since carrier shutdown is system-level, i.e., it applies to all UEs that aggregate the carrier, using signaling that indicates a single terminal to remove or deactivate the SCell would result in wasted signaling. Furthermore, sending a large amount of dedicated signaling is not conducive to network power saving.

[0137] In view of the above, this disclosure aims to provide a communication method, communication device, communication system, storage medium, and program product to solve the above problems.

[0138] Figure 2 is an interactive schematic diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 2, the embodiments of the present disclosure relate to a communication method, which includes:

[0139] Step S2101: The network device sends the second information to the first terminal.

[0140] In some embodiments, the network device sends second information to multiple terminals. The first terminal can be any one of these multiple terminals. The following describes the communication method provided in the embodiments of this disclosure by taking the interaction process between the network device and the first terminal among the multiple terminals as an example.

[0141] It should be noted that these multiple terminals can be terminals in a connected state, that is, the first terminal can be a terminal in a connected state.

[0142] In some embodiments, the first terminal receives second information sent by a network device, but is not limited thereto. The first terminal may also receive second information sent by other entities, in which case step S2101 may be omitted.

[0143] In some embodiments, the first terminal obtains the second information specified by the protocol, in which case step S2101 can be omitted.

[0144] In some embodiments, the first terminal obtains the second information from the upper layer(s), in which case step S2101 can be omitted.

[0145] In some embodiments, the first terminal performs processing to obtain the second information, in which case step S2101 can be omitted.

[0146] In some embodiments, the first terminal autonomously implements the function indicated by the second information, or the above function is a default or default value, in which case step S2101 can be omitted.

[0147] In some embodiments, the second information is used to configure the cell state of the secondary cell corresponding to the first carrier for multiple terminals. It should be noted that the first terminal is one of these multiple terminals, and the second information can be used to configure the cell state of the secondary cell corresponding to the first carrier for the first terminal.

[0148] In some embodiments, the terms "cell", "component carrier (CC)", "frequency carrier", and "carrier frequency" can be used interchangeably.

[0149] In some embodiments, the name of the second information is not limited, and it may be, for example, "first configuration information".

[0150] In some embodiments, the names of information, etc., are not limited to the names described in the embodiments. Terms such as "information", "message", "signal", "signaling", "report", "configuration", "indication", "instruction", "command", "channel", "parameter", "domain", "field", "symbol", "symbol", "codebook", "codeword", "codepoint", "bit", "data", "program", and "chip" can be used interchangeably.

[0151] In some embodiments, the terms "codebook," "codeword," and "precoding matrix" can be used interchangeably. For example, a codebook can be a collection of one or more codewords / precoding matrices.

[0152] In some embodiments, the second information can be carried by the first signaling. That is, the network device can send the first signaling to the first terminal, and the first signaling includes the second information; the first terminal can receive the first signaling sent by the network device to obtain the second information included in the first signaling.

[0153] In some embodiments, the first signaling is any one of Radio Resource Control (RRC) signaling, Media Access Control (MAC) control element (CE), and Downlink Control Information (DCI), but is not limited thereto.

[0154] In some embodiments, the terms “downlink control information (DCI),” “downlink (DL) assignment,” “DL DCI,” “uplink (UL) grant,” and “UL DCI” can be used interchangeably.

[0155] Taking RRC signaling as an example, when configuring a secondary cell for a first terminal, the network device can send RRC signaling including second information to the first terminal to explicitly indicate the initial state of the secondary cell through RRC signaling. Optionally, RRC signaling can be an RRC reconfiguration message, but it is not limited to this.

[0156] In some embodiments, the first carrier can be any one of the multiple carriers used in carrier aggregation.

[0157] In some embodiments, the first carrier is a secondary carrier in carrier aggregation.

[0158] In some embodiments, the second information is used to indicate the cell status of the secondary cell corresponding to the first carrier.

[0159] In some embodiments, the first carrier can be one or more carriers, carriers on one or more frequency bands, or a group or more groups of carriers. That is, the second information is used to indicate any one of the following: the cell status of the secondary cell corresponding to one or more first carriers, the cell status of the secondary cell corresponding to one or more first carriers on one or more frequency bands, or the cell status of the secondary cell corresponding to one or more groups of first carriers. In other words, the network device can indicate the cell status of the secondary cell corresponding to one or more first carriers, one or more first carriers on one or more frequency bands, or one or more groups of first carriers through first signaling such as MAC CE or DCI.

[0160] In some embodiments, the second information is used to indicate the cell status of a group or more groups of secondary cells corresponding to the first carriers, and the carrier group information to which each first carrier belongs can be configured by the network device to multiple terminals.

[0161] In some embodiments, the carrier group information to which each first carrier belongs can be configured by the network device to multiple terminals through third information, which is used to indicate the carrier group to which each first carrier belongs.

[0162] In some embodiments, the name of the third information is not limited, and it may be, for example, "second configuration information".

[0163] In some embodiments, a network device may send third information to multiple terminals, and a first terminal, as one of these multiple terminals, may receive the third information sent by the network device.

[0164] In some embodiments, the third information may be configured by the network device to each terminal when configuring the secondary cell, but is not limited thereto.

[0165] Taking the indication of any one of the following via MAC CE or DCI: the cell status of a secondary cell corresponding to one or more first carriers, the cell status of a secondary cell corresponding to a first carrier in one or more frequency bands, or the cell status of a secondary cell corresponding to one or more groups of first carriers, each bit in MAC CE or DCI can correspond to a first carrier, a frequency band, or a carrier group.

[0166] In some embodiments, when indicating the cell status of secondary cells corresponding to one or more groups of first carriers via DCI, it can also be achieved through a Physical Downlink Control Channel (PDCCH) scrambled with a group Radio Network Temporary Identifier (RNTI). The introduction to group RNTI will be detailed below and will not be repeated here.

[0167] In some embodiments, the second information can also be used to indicate the duration of the cell state of the secondary cell corresponding to the first carrier. As mentioned above, the first carrier can be one or more carriers, carriers in one or more frequency bands, or a group or more groups of carriers. That is, the second information can also be used to indicate any one of the following: the duration of the cell state of the secondary cell corresponding to one or more first carriers, the duration of the cell state of the secondary cell corresponding to one or more first carriers in one or more frequency bands, or the duration of the cell state of the secondary cell corresponding to a group or more groups of first carriers.

[0168] In some embodiments, terms such as “time,” “moment,” “point in time,” and “time location” can be used interchangeably, as can terms such as “time,” “duration,” “segment,” “time window,” and “window.”

[0169] In some embodiments, the cell state can be multiple. For example, the cell state indicated by the second information can be any one of the first state, the second state, the third state, and the fourth state, but is not limited thereto.

[0170] In some embodiments, the first state is a cell state that allows the first terminal to retain the configuration of the secondary cell corresponding to the first carrier but not to perform measurements of the secondary cell corresponding to the first carrier. That is, the terminal behavior allowed in the first state is: retaining the configuration of the secondary cell corresponding to the first carrier but not performing measurements of the secondary cell corresponding to the first carrier; or, for a secondary cell configured in the first state, the terminal can retain the configuration of the secondary cell but not perform measurements of the secondary cell.

[0171] In some embodiments, the name of the first state is not limited, and it may be, for example, "SCell closed state", "SCell OFF state", etc.

[0172] In some embodiments, the second state indicates that the secondary cell corresponding to the first carrier has not yet been configured. For a secondary cell configured in the second state, the first terminal may not retain the configuration of the secondary cell and does not need to perform secondary cell measurements. That is, the allowed terminal behavior in the second state is: not retaining the configuration of the secondary cell corresponding to the first carrier and not performing measurements of the secondary cell corresponding to the first carrier; or, for a secondary cell configured in the second state, the terminal may not retain the configuration of the secondary cell and does not need to perform measurements of the secondary cell.

[0173] In some embodiments, the name of the second state is not limited, and may be, for example, "SCell not configured state", "not configured state", etc.

[0174] In some embodiments, the third state indicates that the secondary cell corresponding to the first carrier is configured but not activated. For a secondary cell configured in the third state, the first terminal may retain the configuration of the secondary cell and perform some measurements for that secondary cell. That is, the terminal behavior allowed in the third state is: retaining the configuration of the secondary cell corresponding to the first carrier and performing some measurements for that secondary cell; or, for a secondary cell configured in the third state, the terminal may retain the configuration of the secondary cell and perform some measurements for that secondary cell.

[0175] In some embodiments, the name of the third state is not limited, and it may be, for example, "SCell configuration inactive state".

[0176] In some embodiments, the fourth state is used to indicate that the secondary cell corresponding to the first carrier is configured and activated. For a secondary cell configured in the fourth state, the first terminal can retain the configuration of the secondary cell and perform secondary cell measurements. That is, the terminal behavior allowed in the fourth state is: retaining the configuration of the secondary cell corresponding to the first carrier and performing secondary cell measurements; or, for a secondary cell configured in the fourth state, the terminal can retain the configuration of the secondary cell and perform measurements for the secondary cell.

[0177] In some embodiments, the name of the fourth state is not limited, and it may be, for example, "SCell configuration and activation state", "SCell enabled state", "SCell open state", "SCell ON state", etc.

[0178] In some embodiments, the first terminal may configure the cell status of the secondary cell corresponding to the first carrier and decide whether to perform a measurement of the secondary cell corresponding to the first carrier based on the received second information.

[0179] In step S2102, the network device sends the first information to the first terminal.

[0180] In some embodiments, a network device sends first information to multiple terminals. The first terminal can be any one of these multiple terminals. The following describes the communication method provided in this disclosure embodiment using the interaction process between the network device and the first terminal among the multiple terminals as an example.

[0181] In some embodiments, the first terminal receives first information sent by a network device, but is not limited thereto. The first terminal may also receive first information sent by other entities, in which case step S2102 may be omitted.

[0182] In some embodiments, the first terminal obtains the first information specified by the protocol, in which case step S2102 can be omitted.

[0183] In some embodiments, the first terminal obtains the first information from the upper layer(s), in which case step S2102 can be omitted.

[0184] In some embodiments, the first terminal performs processing to obtain the first information, in which case step S2102 can be omitted.

[0185] In some embodiments, the first terminal autonomously implements the function indicated by the first information, or the above function is a default or default value, in which case step S2102 can be omitted.

[0186] In some embodiments, the first information is used to instruct multiple terminals to perform secondary cell removal or secondary cell deactivation on the secondary cell corresponding to the first carrier. The multiple terminals include the first terminal, so the first information can be used to instruct the first terminal to perform secondary cell removal or secondary cell deactivation.

[0187] In some embodiments, the first information may be used to instruct multiple terminals to change the cell state of the secondary cell obtained by aggregating the first carrier.

[0188] These multiple terminals can be multiple terminals that aggregate the first carrier into a secondary cell. That is, the first information can be used to instruct the multiple terminals that aggregate the first carrier into a secondary cell to perform secondary cell removal or secondary cell deactivation, or in other words, the first information can be used to instruct the multiple terminals that aggregate the first carrier into a secondary cell to change the cell state of the secondary cell obtained by aggregating the first carrier.

[0189] Alternatively, these multiple terminals can be multiple terminals performing carrier aggregation based on the first carrier. That is, the first information can be used to instruct the multiple terminals performing carrier aggregation based on the first carrier to perform secondary cell removal or secondary cell deactivation on the secondary cell corresponding to the first carrier. In other words, the first information can be used to instruct the multiple terminals performing carrier aggregation based on the first carrier to change the cell state of the secondary cell obtained by aggregating the first carrier.

[0190] In some embodiments, the first information can be used to perform secondary cell removal or secondary cell deactivation on one or more secondary cells. Alternatively, the first information can be used to change or update the cell status of one or more secondary cells.

[0191] In some embodiments, the name of the first information is not limited, and it may be, for example, "indication information", "cell status indication information", etc.

[0192] In some embodiments, a network device may group terminals within its network coverage area to divide terminals within its network coverage area into multiple terminal groups.

[0193] In some embodiments, the network device may group terminals that aggregate the same carrier into a secondary cell into a terminal group. Optionally, the network device may group terminals that aggregate the same carrier into a secondary cell and whose secondary cells are assigned the same SCell index into a terminal group.

[0194] In some embodiments, the segmented terminal group can be identified by a first identifier. Optionally, the first identifier can be a group RNTI, but is not limited thereto.

[0195] In some embodiments, the network device can configure a first terminal group identifier for each terminal according to the divided terminal groups. Optionally, the network device can configure the first identifier as the first terminal group identifier for each terminal. Each terminal can receive the first identifier sent by the network device and store the received first identifier as the first terminal group identifier for subsequent confirmation of its own terminal group. The first identifier can be a group RNTI, therefore, the first terminal group identifier can also be a group RNTI.

[0196] It should be noted that for terminals assigned to the same terminal group, the network device configures the same First Terminal Group Identifier (RNTI). However, for terminals assigned to different terminal groups, the network device can configure different First Terminal Group Identifiers. In other words, the network device can configure the same group RNTI for terminals assigned to the same terminal group.

[0197] In some embodiments, when a network device decides to shut down the first carrier for energy-saving reasons, it can generate first information by using a first identifier to identify a terminal group consisting of multiple terminals. The first information is obtained by scrambling the first identifier, thereby enabling the network device to send the first information obtained by scrambling the first identifier to the first terminal. As mentioned above, these multiple terminals may be multiple terminals that aggregate the first carrier into secondary cells, or in other words, these multiple terminals may be multiple terminals that perform carrier aggregation based on the first carrier.

[0198] In some embodiments, the first information is used to perform secondary cell removal or secondary cell deactivation on a secondary cell. In this case, the network device can send the first information on the secondary cell, and correspondingly, the first terminal can receive the first information sent by the network device on the secondary cell.

[0199] In some embodiments, the first information is used to perform secondary cell removal or secondary cell deactivation on multiple secondary cells. The network device can send the first information on the first secondary cell or the primary cell, and correspondingly, the first terminal can receive the first information sent by the network device on the first secondary cell or the primary cell. The first secondary cell can be at least one of multiple secondary cells.

[0200] In some embodiments, when the first information is obtained by scrambling the first identifier, if the first information is used to perform secondary cell removal or secondary cell deactivation on multiple secondary cells, the first information may also include index information (i.e., SCell index) of multiple secondary cells, so as to implement the indication for removal or deactivation of these multiple cells through the index information of multiple secondary cells.

[0201] It should be noted that when multiple cells are removed or deactivated by using the index information of multiple secondary cells, the SCell index configured for the same carrier is the same for terminals within the terminal group identified by the first identifier.

[0202] In some embodiments, the first information can be carried via PDCCH. That is, network devices can instruct multiple terminals to remove or deactivate one or more secondary cells by sending a PDCCH scrambled with group RNTI (i.e., the first identifier).

[0203] Through the above embodiments, the first information can be used to instruct multiple terminals in a terminal group identified by the first identifier to perform cell removal or cell deactivation, so as to realize cell removal or cell deactivation instruction based on group-based signaling.

[0204] In some embodiments, cell removal or cell deactivation can also be indicated via broadcast-based signaling.

[0205] In some embodiments, a second identifier that the network device has configured for the terminal can be reused to implement a cell removal or cell deactivation indication based on broadcast-based signaling.

[0206] In some embodiments, the second identifier may be an identifier for paging messages, or the second identifier may be an identifier for system information broadcasting.

[0207] Optionally, the second identifier is an identifier used for paging messages. The second identifier can be a Paging Radio Network Temporary Identifier (P-RNTI), but is not limited to this. Optionally, the second identifier is an identifier used for system information broadcasting. The second identifier can be a System Information Radio Network Temporary Identifier (SI-RNTI), but is not limited to this.

[0208] In some embodiments, the network device may configure a second identifier for the paging message as a device paging identifier to the terminal. The terminal may receive the second identifier for the paging message sent by the network device and store the received second identifier as a device paging identifier for subsequent parsing of the first information obtained by scrambling based on the second identifier. The second identifier for the paging message may be a P-RNTI, and therefore, the device paging identifier may also be a P-RNTI.

[0209] In some embodiments, the network device may configure a second identifier for system information broadcasting as a system information identifier to the terminal. The terminal may receive the second identifier for system information broadcasting sent by the network device and store the received second identifier as a system information identifier for subsequent parsing of the first information obtained by scrambling based on the second identifier. The second identifier for system information broadcasting may be SI-RNTI, and therefore, the system information identifier may also be SI-RNTI.

[0210] It should be noted that by reusing the second identifier used for paging messages and the second identifier used for system information broadcasting, the network device can use the second identifier to scramble the first information, thereby broadcasting the first information scrambled based on the second identifier, so that the first terminal can receive the first information scrambled based on the second identifier.

[0211] In some embodiments, when the first information obtained by scrambling the second identifier is used to implement cell removal or cell deactivation indication, the network device may also divide the terminal group. The division method can be referred to above and will not be repeated here.

[0212] In some embodiments, when a cell removal or cell deactivation indication is implemented using the first information obtained by scrambling the second identifier, the divided terminal group can be identified by a third identifier. Optionally, the third identifier can be a group identifier (group ID), but is not limited thereto.

[0213] In some embodiments, the network device can configure a second terminal group identifier for each terminal according to the divided terminal groups. Optionally, the network device can configure a third identifier as the second terminal group identifier for each terminal. Each terminal can receive the third identifier sent by the network device and store the received third identifier as the second terminal group identifier for subsequent determination of its own terminal group. The third identifier can be a group ID, therefore, the second terminal group identifier can also be a group ID.

[0214] It should be noted that for terminals assigned to the same terminal group, the network device configures the same second terminal group identifier. However, for terminals assigned to different terminal groups, the network device can configure different second terminal group identifiers. In other words, the network device can configure the same group ID for terminals assigned to the same terminal group.

[0215] In some embodiments, when a network device decides to shut down the first carrier for energy-saving reasons, it may carry a third identifier in the first information to identify a terminal group consisting of multiple terminals. That is, the third identifier for identifying the terminal group is carried in the first information obtained by scrambling with a second identifier, thereby enabling the broadcast of the first information including the third identifier. As mentioned above, these multiple terminals may be multiple terminals that aggregate the first carrier into secondary cells, or in other words, these multiple terminals may be multiple terminals that perform carrier aggregation based on the first carrier.

[0216] In some embodiments, when the first information is obtained by scrambling the second identifier, the first information is used to perform secondary cell removal or secondary cell deactivation on one or more secondary cells. The first information also includes index information (i.e., SCell index) of the one or more secondary cells, so as to implement the indication for removal or deactivation of the one or more cells through the index information of the one or more secondary cells.

[0217] Optionally, if the first information is obtained by scrambling the second identifier, and if the first information is used to instruct multiple terminal groups to remove or deactivate one or more secondary cells, the first information may include the third identifiers of these multiple terminal groups, and each third identifier may correspond to an index. Then, for a terminal whose device paging identifier matches the second identifier used for paging messages or whose system information identifier matches the second identifier used for system information broadcasting, it can determine the secondary cell that it needs to remove or deactivate based on its own second device group identifier, the third identifier carried in the first information, and the corresponding index information.

[0218] It should be noted that when multiple cells are removed or deactivated by using the index information of multiple secondary cells, the SCell index configured for the same carrier is the same for terminals within the terminal group identified by the third identifier.

[0219] In some embodiments, the first information can be carried via PDCCH. That is, network devices can instruct multiple terminals to remove or deactivate one or more secondary cells by sending a PDCCH scrambled with P-RNTI or SI-RNTI (i.e., the second identifier).

[0220] It should be noted that whether the secondary cell is removed or activated via the first information instruction can be determined by the network device based on requirements and network conditions. Optionally, if nothing is transmitted on the first carrier of shutdown, the network device can instruct the terminal to remove the SCell; if a Synchronization Signal Block (SSB) signal is transmitted on the first carrier of shutdown, or even if no SSB signal is transmitted on the first carrier of shutdown but the network device has configured a measurable reference carrier for the SCell, the network device can instruct the terminal to deactivate the SCell.

[0221] In some embodiments, the terms "synchronization signal block (SSB)," "synchronization signal (SS)," "reference signal (RS)," "pilot," and "pilot signal" can be used interchangeably.

[0222] In step S2103, the first terminal removes or deactivates the secondary cell corresponding to the first carrier based on the first information.

[0223] In some embodiments, the first information is obtained by scrambling a first identifier used to identify a terminal group, and only terminals whose first terminal group identifier matches the first identifier can successfully parse the first information.

[0224] In some embodiments, the first terminal group identifier of the first terminal matches the first identifier used for scrambling the first information. Therefore, the first terminal can remove or deactivate the secondary cell corresponding to the first carrier based on the first information.

[0225] In some embodiments, the first information is used to perform secondary cell removal or secondary cell deactivation on a secondary cell. The first terminal will receive the first information on the secondary cell, and thus can perform secondary cell removal or secondary cell deactivation on the secondary cell for which the first information is received.

[0226] In some embodiments, the first information is used to perform secondary cell removal or secondary cell deactivation on multiple secondary cells. In this case, the first terminal may receive the first information in the first secondary cell or the primary cell. At this time, the first information may include index information of multiple secondary cells. The first terminal may perform secondary cell removal or secondary cell deactivation based on the secondary cell indicated by the index information included in the first information.

[0227] In some embodiments, the first information is obtained by scrambling a second identifier used for paging messages, and only terminals whose assigned device paging identifier matches the second identifier can successfully parse the first information.

[0228] In some embodiments, the first information is obtained by scrambling a second identifier used for paging messages. The device paging identifier configured by the network device for the first terminal matches the second identifier used to scramble the first information. Based on the first information, the first terminal can remove or deactivate a secondary cell corresponding to the first carrier. Optionally, the first terminal can remove or deactivate one or more secondary cells based on the index information in the first information.

[0229] In some embodiments, the first information is obtained by scrambling a second identifier used for system information broadcasting, and only terminals whose assigned system information identifier matches the second identifier can successfully parse the first information.

[0230] In some embodiments, the first information is obtained by scrambling a second identifier used for system information broadcasting. The system information identifier configured by the network device for the first terminal matches the second identifier used to scramble the first information. Based on the first information, the first terminal can remove or deactivate a secondary cell corresponding to the first carrier. Optionally, the first terminal can remove or deactivate one or more secondary cells based on the index information in the first information.

[0231] In some embodiments, the first information is obtained by scrambling a second identifier used for paging messages or a second identifier used for system information broadcasting. The first information may also include a third identifier used to identify a terminal group. The first terminal can match the second terminal group identifier configured for it by the network device with the third identifier included in the first information to determine whether it needs to perform secondary cell removal or secondary cell deactivation.

[0232] In some embodiments, if the second terminal group identifier of the first terminal matches the third identifier included in the first information, the first terminal can remove or deactivate the secondary cell corresponding to the first carrier based on the first information. Optionally, the third identifier included in the first information may correspond to index information, so that the first terminal can perform secondary cell removal or deactivation for the secondary cell indicated by the index information corresponding to the third identifier that matches its own second terminal identifier.

[0233] In some embodiments, “get,” “obtain,” “receive,” “transmit,” “bidirectional transmission,” and “send and / or receive” can be used interchangeably and can be interpreted as receiving from other entities, obtaining from protocols, obtaining from higher layers, obtaining through self-processing, or autonomous implementation, among other meanings.

[0234] In some embodiments, terms such as “send,” “transmit,” “report,” “distribute,” “transmit,” “bidirectional transmission,” “send and / or receive” can be used interchangeably.

[0235] In some embodiments, terms such as "certain," "preset," "default," "set," "indicated," "a certain," "any," and "first" can be used interchangeably. "Certain A," "preset A," "default A," "set A," "indicated A," "a certain A," "any A," and "first A" can be interpreted as A pre-defined in a protocol or the like, or as A obtained through setting, configuration, or instruction, or as specific A, a certain A, any A, or first A, but are not limited thereto.

[0236] In some embodiments, the determination or judgment can be made by a value represented by 1 bit (0 or 1), or by a true or false value (boolean), or by a comparison of numerical values ​​(e.g., a comparison with a predetermined value), but is not limited thereto.

[0237] In some embodiments, "not expecting to receive" can be interpreted as not receiving on time domain resources and / or frequency domain resources, or as not performing subsequent processing on the data after receiving it; "not expecting to send" can be interpreted as not sending, or as sending but not expecting the receiver to respond to the sent content.

[0238] The communication method involved in the embodiments of this disclosure may include at least one of steps S2101 to S2103. For example, step S2102 may be implemented as an independent embodiment, step S2103 may be implemented as an independent embodiment, step S2101+S2102 may be implemented as an independent embodiment, step S2101+S2103 may be implemented as an independent embodiment, and step S2102+S2103 may be implemented as an independent embodiment, but is not limited thereto.

[0239] In some embodiments, steps S2101 and S2102 may be performed in an alternate order or simultaneously.

[0240] In some embodiments, steps S2101 and S2103 are optional, and one or more of these steps may be omitted or substituted in different embodiments.

[0241] In some embodiments, steps S2101 and S2102 are optional, and one or more of these steps may be omitted or substituted in different embodiments.

[0242] In some embodiments, other optional implementations described before or after the specification corresponding to FIG2 may be referred to.

[0243] According to the solution provided in the embodiments of this disclosure, a method for indicating cell status in carrier aggregation can be provided to introduce effective signaling to notify the UE of the cell status it is working on in order to save signaling overhead and network power consumption.

[0244] In some embodiments, group-based or broadcast-based signaling may be introduced to indicate SCell removal or deactivation.

[0245] In some embodiments, when a carrier is shut down, the network can instruct the UE to remove or deactivate a SCell by sending group-based signaling. Optionally, the network configures a specific group RNTI for the terminal. For example, the network assigns terminals that aggregate a carrier into SCells (or further define them with the same SCell index) to a group and configures the same group RNTI for these terminals. When the network decides to shut down the carrier for energy saving, the network can send a PDCCH through the group RNTI, indicating the SCell status in the PDCCH, such as indicating SCell removal or SCell deactivation. A PDCCH can indicate the status of only one SCell, for example, a PDCCH scrambled with the group RNTI sent on the SCell indicates the status of that SCell. A PDCCH can also indicate the status of multiple SCells, in which case multiple SCell indices can be used to indicate the status of multiple SCells (in which case the SCell index configured for the same carrier is the same for UEs in this group). In some embodiments, a terminal in connected state receives the group RNTI configured by the network and listens to the PDCCH scrambled with the group RNTI. If a PDCCH scrambled by group RNTI is detected, the terminal should remove or deactivate the SCell as indicated in the PDCCH.

[0246] In some embodiments, group-based SCell removal or deactivation can be extended to broadcast-based SCell removal or deactivation. For example, P-RNTI or SI-RNTI can be reused to indicate SCell removal or deactivation in the PDCCH (e.g., a short message in paging DCI). UEs that aggregate the carrier into SCells perform SCell removal or deactivation according to network instructions. UEs that do not aggregate the carrier into SCells ignore the network instruction information.

[0247] Optionally, if nothing is transmitted on the shutdown carrier, the network can instruct the terminal to remove the SCell. If the shutdown carrier is still transmitting an SSB signal, or even if no SSB signal is transmitted but the network has configured a measurable reference carrier for the SCell, the network can instruct the terminal to deactivate the SCell.

[0248] In some embodiments, RRC, MAC CE, or DCI signaling may also be introduced to indicate the SCell ON / OFF status.

[0249] In some embodiments, when configuring a SCell, the network can explicitly indicate the initial state of the SCell, such as ON or OFF, through RRC signaling (e.g., RRC reconfiguration messages). Terminal behavior in the SCell OFF state can include one or more of the following: the terminal retains the SCell configuration and does not perform SCell measurements.

[0250] In some embodiments, the network uses MAC CE / DCI to indicate the ON / OFF status of one or more carriers, carriers on one or more bands, or a group or more carrier groups. If the indication is based on a carrier group, the group information to which the carrier belongs can be configured to the UE when configuring the SCell. Each bit in the MAC CE / DCI corresponds to a carrier / cell, a band, or a carrier group. The MAC CE can also indicate the specific on / off duration information of the carrier / band / carrier group. The DCI indication of the ON / OFF status of a group of carriers can also be implemented through a PDCCH scrambled with group RNTI.

[0352] It should be understood that the division of units or modules in the above device is only a logical functional division. In actual implementation, they can be fully or partially integrated into a single physical entity, or they can be physically separated. Furthermore, the units or modules in the device can be implemented by a processor calling software: for example, the device includes a processor connected to a memory containing instructions. The processor calls the instructions stored in the memory to implement any of the above methods or to implement the functions of the units or modules in the above device. The processor can be, for example, a general-purpose processor, such as a Central Processing Unit (CPU) or a microprocessor, and the memory can be internal or external to the device. Alternatively, the units or modules in the device can be implemented in the form of hardware circuits. The functionality of some or all of the units or modules can be achieved through the design of these hardware circuits, which can be understood as one or more processors. For example, in one implementation, the hardware circuit is an application-specific integrated circuit (ASIC). The functionality of some or all of the units or modules is achieved through the design of the logical relationships between the components within the circuit. In another implementation, the hardware circuit can be implemented using a programmable logic device (PLD). Taking a field-programmable gate array (FPGA) as an example, it can include a large number of logic gates. The connection relationships between the logic gates are configured through configuration files, thereby achieving the functionality of some or all of the units or modules. All units or modules of the above device can be implemented entirely through processor-called software, entirely through hardware circuits, or partially through processor-called software with the remaining parts implemented through hardware circuits.

[0353] In this embodiment, the processor is a circuit with signal processing capabilities. In one implementation, the processor can be a circuit with instruction read and execute capabilities, such as a Central Processing Unit (CPU), a microprocessor, a graphics processing unit (GPU) (which can be understood as a microprocessor), or a digital signal processor (DSP). In another implementation, the processor can implement certain functions through the logical relationships of hardware circuits. The logical relationships of the aforementioned hardware circuits are fixed or reconfigurable. For example, the processor is a hardware circuit implemented using an application-specific integrated circuit (ASIC) or a programmable logic device (PLD), such as an FPGA. In a reconfigurable hardware circuit, the process of the processor loading a configuration document and configuring the hardware circuit can be understood as the process of the processor loading instructions to implement the functions of some or all of the above units or modules. Furthermore, it can also be a hardware circuit designed for artificial intelligence, which can be understood as an ASIC, such as a Neural Network Processing Unit (NPU), a Tensor Processing Unit (TPU), or a Deep Learning Processing Unit (DPU).
