Description

Technical Field

[0001] This application relates to the field of communications, and more particularly to a communication method, apparatus, communication device, and storage medium. Background Technology

[0002] In uplink carrier aggregation in New Radio (NR), the number of uplink carriers that can be aggregated reported by the terminal must be carriers that can be transmitted simultaneously, which depends on the number of transmit links of the terminal. The maximum number of uplink carriers that the network side configures and activates for the terminal is also equal to the number of uplink carriers that can be aggregated reported by the terminal.

[0003] In carrier aggregation scenarios, NR allows the configuration of a secondary cell (SCell) for the terminal in addition to the special cell (SpCell) that can transmit the Physical Uplink Control Channel (PUCCH). This SCell is called the PUCCH SCell. The base station configures the Hybrid Automatic Repeat Request (HARQ-ACK) feedback for each downlink serving cell of the terminal on either the SpCell or the PUCCH SCell.

[0004] Due to the limitations of the uplink transmission link, such as Figure 1 As shown, the number of uplink carriers / bands currently configured and activated can only be equal to the number of uplink transmit links at most. However, the number of downlink carriers / bands aggregated is greater than the number of uplink carriers / bands. Therefore, for multiple spectrums, all downlink carriers can be aggregated, but uplink carriers cannot be fully aggregated, and sufficient spectrum resources cannot be fully utilized.

[0094] The present invention will be further described in detail below with reference to the embodiments, starting with a description of the relevant technologies.

[0095] In related technologies, a potential optimization method is proposed: the number of uplink carriers / bands configured or activated by the base station for the terminal can be greater than the number of uplink transmit links of the terminal. Then, signaling is used to instruct the terminal on which carriers / cells can perform uplink transmission / carrier aggregation. This achieves flexible spectrum utilization and decouples it from the terminal's uplink transmit link capacity. However, there is a configuration problem regarding the cells transmitting PUCCH. Since the base station can use dynamic signaling to instruct the terminal on the uplink carriers / cells currently used / aggregated, these cells may not be SpCells or PUCCH SCells. The terminal's downlink HARQ-ACK feedback does not know which uplink cell to transmit in. Therefore, it is necessary to solve the configuration and determination problem of cells that can transmit PUCCH in the uplink carrier handover scenario of dynamic carrier aggregation, that is, to determine which cell's PUCCH will transmit the HARQ feedback of a certain cell's Physical Downlink Shared Channel (PDSCH).

[0096] Based on this, the method provided in this embodiment of the invention involves a network device determining a first signaling, which is used to indicate at least two cells activated by the terminal, or to indicate at least two carrier units for carrier aggregation by the terminal; the first signaling and configuration information are used by the terminal to determine the cell for transmitting HARQ feedback; the configuration information includes at least two first cells configured with PUCCH resources; the first signaling is sent to the terminal; correspondingly, the terminal receives the first signaling from the network device; the first signaling is used to indicate at least two cells activated by the terminal; or the first signaling is used to indicate at least two carrier units for carrier aggregation by the terminal; the cell for transmitting HARQ feedback is determined according to the first signaling and configuration information; the configuration information includes at least two first cells configured with PUCCH resources.

[0104] In some embodiments, the configuration information is determined based on a preset protocol, or configured by a network device to the terminal.

[0105] In some embodiments, the at least two first cells are used for terminals to transmit HARQ feedback of the same cell.

[0106] In some embodiments, the configuration information includes at least one of the following:

[0107] Information on at least two primary communities;

[0108] Cell index; the cell index is used to associate at least two first cells, or to associate cells that transmit HARQ feedback.

[0109] In some embodiments, the configuration information further includes:

[0111] Specifically, the configuration information can be provided to the network device and the terminal in advance through a protocol-predefined method; or the network device can determine the configuration information and send it to the terminal.

[0112] Specifically, network devices can configure at least two cells for terminals that can transmit HARQ feedback or are configured with PUCCH resources;

[0113] The network device can also configure the sorting or priority of the at least two cells for the terminal.

[0114] In application, the network device sends a first signaling instruction to indicate at least two cells activated by the terminal or to indicate carrier units for carrier aggregation performed by the terminal; here, indicating at least two cells activated by the terminal or to indicate carrier units for carrier aggregation performed by the terminal refers to the cells or carrier units that the network device indicates the terminal can perform uplink transmission. The first signaling instruction and configuration information together determine which cell's PUCCH specifically transmits the HARQ feedback of the PDSCH.

[0115] In some embodiments, the at least two cells or the at least two carrier units are used for uplink transmission.

[0116] In some embodiments, the first signaling is used to indicate the dormant uplink (UL) bandwidth portion (BWP) of the cell or to activate the UL BWP;

[0117] Corresponding to the first signaling indication activating the UL BWP, the cell corresponding to the UL BWP is in an active state, capable of carrier aggregation or uplink transmission;

[0119] In some embodiments, the first signaling is downlink control information (DCI).

[0120] Figure 3 A flowchart illustrating another communication method provided in an embodiment of the present invention; as shown Figure 3 As shown, the method is applied to terminals such as mobile phones, smartphones, laptops, digital radio receivers, personal digital assistants (PDAs), tablet computers (PADs), portable multimedia players (PMPs), wearable devices (such as smart bracelets, smartwatches, etc.), navigation devices, etc.; the method includes:

[0121] Step 301: Receive first signaling from the network device; the first signaling is used to indicate at least two cells activated by the terminal; or, the first signaling is used to indicate at least two carrier units for carrier aggregation by the terminal;

[0122] Step 302: Determine the cell transmitting HARQ feedback based on the first signaling and configuration information; the configuration information includes: at least two first cells configured with PUCCH resources.

[0123] In some embodiments, the configuration information is determined based on a preset protocol, or configured by a network device to the terminal.

[0124] In some embodiments, the at least two first cells are used for terminals to transmit HARQ feedback of the same cell.

[0125] In some embodiments, the configuration information includes at least one of the following:

[0126] Information on at least two primary communities;

[0127] Cell index; the cell index is used to associate at least two first cells, or to associate cells that transmit HARQ feedback.

[0128] In some embodiments, the configuration information further includes: the sorting or priority of each of the at least two first cells.

[0129] The terminal determines the cell for transmitting HARQ feedback information based on the order or priority of the cells configured with PUCCH resources (i.e., the at least two first cells mentioned in the configuration information) configured by the network device, combined with the carrier unit indicating uplink carrier aggregation or the cell indicating activation of the current first signaling (the cell for transmitting HARQ feedback information determined here is the cell on which the terminal transmits HARQ feedback on the PUCCH of at least one first cell).

[0130] In some embodiments, the at least two cells or at least two carrier units are used for uplink transmission.

[0131] In some embodiments, determining the cell transmitting HARQ feedback includes at least one of the following:

[0132] The cell for transmitting HARQ feedback is determined based on at least two cells indicated by the first signaling, and the priorities of the at least two first cells and the at least two first cells.

[0133] The cell for transmitting HARQ feedback is determined based on at least two carrier units indicated by the first signaling and the priority of the first cell corresponding to the at least two carrier units.

[0134] In some embodiments, determining the cell transmitting HARQ feedback includes at least one of the following:

[0135] The cell with the highest priority among the at least two cells indicated by the first signaling is determined as the cell that transmits HARQ feedback;

[0136] The cell with the highest priority among the first cells corresponding to the at least two carrier units indicated by the first signaling is determined as the cell that transmits HARQ feedback.

[0137] An application example is provided, assuming that the configuration information includes: cells configured with PUCCH resources, specifically cell 1, cell 2, and cell 3, with priority from high to low as cell 1, cell 2, and cell 3; the first signaling instructs the terminal to activate cell 2, cell 3, and cell 4;

[0138] Based on configuration information and the first signaling, the terminal determines that the cells that can transmit HARQ feedback include: cell 2 and cell 3; and considering priority, cell 2 is selected as the final cell for the terminal to transmit HARQ feedback.

[0139] Another application example is provided, assuming that the configuration information is the same as the example above, including: cells configured with PUCCH resources, specifically cell 1, cell 2, and cell 3, with priority from high to low as cell 1, cell 2, and cell 3;

[0140] The first signaling instruction indicates that the carrier units for carrier aggregation performed by the terminal are carrier unit 1 (corresponding to cell 1) and carrier unit 3 (corresponding to cell 3);

[0141] Based on configuration information and the first signaling, the terminal determines that the cells that can transmit HARQ feedback include: cell 1 and cell 3; and considering priority, cell 1 is selected as the final cell for the terminal to transmit HARQ feedback.

[0142] In some embodiments, determining the cell transmitting HARQ feedback includes at least one of the following:

[0143] The cell transmitting HARQ feedback is determined based on at least two cells indicated by the first signaling, the cell index, and the at least two first cells;

[0144] The cell for transmitting HARQ feedback is determined based on at least two carrier units indicated by the first signaling, the cell index, and the first cell corresponding to the at least two carrier units.

[0145] For example, the cell index is used to associate cells that transmit HARQ feedback. The cell index can be understood as a virtual index that directly associates with cells that transmit HARQ feedback. For example, the cell index can be set to associate with the Nth cell in the first signaling or with the Nth cell in the order determined by the first signaling and configuration information. N is associated with the value of the cell index, for example, N equals the cell index.

[0146] Assume the configuration information includes: cell index is index 1, and cells configured with PUCCH resources include cell 1, cell 2, and cell 3. The first signaling instruction instructs the terminal to activate cells 2, 3, and 4.

[0147] Based on the configuration information and the first signaling, the terminal uses cell 2, which corresponds to cell 3, as the first cell in the sequence number or serial number. That is, cell 2, the terminal uses cell 2 as the cell for the final terminal transmission of HARQ feedback.

[0148] Another application example is provided, assuming the configuration information is the same as the example above, including: the cell index is index 1, and the cells configured with PUCCH include cell 1, cell 2, and cell 3. The first signaling instructs the terminal to activate cell 3 and cell 4.

[0149] Based on the configuration information and the first signaling, the terminal determines that index 1 corresponds to the first cell in cell 3, which is sorted by number or sequence number, i.e., cell 3. The terminal uses cell 3 as the cell for the final terminal transmission of HARQ feedback.

[0150] Another application example is provided, in which the cell index is used to associate at least two first cells. The cell index can be understood as a real index used to associate the corresponding cells.

[0151] Suppose that the configuration information includes: cell index is index 1 (associated with cell 1 and cell 2); or, it includes multiple indexes, each associated with a cell, such as: index 2 (associated with cell 1) and index 3 (associated with cell 2); the cells configured with PUCCH include cell 1 and cell 2; the priority of the above cells from high to low is cell 1 and cell 2.

[0152] The first signaling instruction instructs the terminal to activate cells 2 and 3;

[0153] Based on the configuration information and the first signaling, the terminal determines that the cells that can transmit HARQ feedback include: cell 2.

[0154] Another application example is provided, where the configuration information includes: cells configured with PUCCH include cell 1 and cell 2; the cell index is index 1; or, it includes multiple indices, each associated with a cell, such as: index 2 (associated with cell 1) and index 3 (associated with cell 2). The first signaling instructs the terminal to activate cell 2 and cell 3.

[0155] The network device can also send other signaling to indicate that the terminal's current HARQ feedback cell index 1 is associated with cell 2, or to indicate that the terminal's current HARQ feedback cell index is index 3. Based on the configuration information and the first signaling, the terminal determines that the cells that can transmit HARQ feedback include: cell 2.

[0156] In this way, the cell transmitting HARQ feedback can be modified by changing the association between the cell index (here referring to the virtual cell index) and the cell.

[0157] In some embodiments, a network device can determine which cells a terminal can perform uplink transmission, activate, or perform carrier aggregation by using the indication of a dormant UL BWP.

[0158] Specifically, the first signaling is used to instruct the cell to either sleep or activate the UL BWP;

[0159] Corresponding to the first signaling indication activating the UL BWP, the cell corresponding to the UL BWP is in an active state, capable of carrier aggregation or uplink transmission;

[0160] Corresponding to the first signaling indication that the UL BWP is in a dormant state, the cell corresponding to the UL BWP is either in an inactive state or cannot perform carrier aggregation or uplink transmission.

[0161] In some embodiments, the first signaling is DCI.

[0162] In this embodiment of the invention, through protocol predefinition and / or the first signaling of the network device, it is indicated that the HARQ feedback of a cell of the terminal can be transmitted on the PUCCH resources of at least two cells. That is, multiple uplink cells associated with a cell for transmitting HARQ feedback PUCCH signaling can be configured for a cell, so that the terminal can dynamically adapt to different UL carrier aggregation configuration scenarios. The terminal always has the configuration of cells with PUCCH resources configured, which can be used for HARQ feedback of PDSCH.

[0163] Provide an application example, such as Figure 4 As shown, the communication method includes:

[0164] Step 401: The network device sends configuration information to the terminal;

[0165] The configuration information includes:

[0166] The network device is configured for the terminal with at least two cells that have PUCCH resources or can transmit HARQ feedback information;

[0167] The sorting or priority of the at least two cells.

[0168] Step 402: The network device sends the first signaling to the terminal;

[0169] The first signaling is used to indicate the cell activated by the terminal, or the carrier unit performing carrier aggregation, or the carrier unit or cell that can perform uplink transmission.

[0170] Step 403: The terminal determines the cell from which HARQ feedback is transmitted;

[0171] Specifically, the PUCCH of which cell the HARQ feedback is transmitted is determined based on at least one of the following:

[0172] The configuration information mentions at least two cells;

[0173] The sorting or priority of the at least two cells mentioned in the configuration information;

[0174] The cell that the terminal is activating, or the carrier unit that is performing carrier aggregation, or the carrier unit or cell that can perform uplink transmission.

[0175] Here, the terminal selects the cell with the highest priority or order in the configuration information according to the first signaling to transmit the PUCCH. The PUCCH is used by the terminal to transmit HARQ feedback, that is, the cell with the highest priority or order is selected by the terminal as the cell for transmitting HARQ feedback according to the first signaling.

[0176] For example, the network device configures N uplink cells for the terminal; the network device also configures M corresponding cells (M<=N) for a certain downlink cell of the terminal that can transmit PUCCH or have PUCCH resources. Furthermore, the network device configures the priority or order of the M cells.

[0177] The network device instructs the terminal via the first signaling to perform uplink carrier aggregation on the carrier unit, or to instruct the terminal on the number of cells that can perform uplink transmission, which is T (T<=N);

[0178] The terminal determines the cells corresponding to the T cells or carrier units indicated by the first signaling and the union of the M cells. The cell with the highest priority or highest order in the union is used as the uplink cell for transmitting the HARQ feedback of the downlink cell. That is, the HARQ feedback of the PDSCH of the downlink cell is transmitted on the PUCCH of the uplink cell.

[0179] The uplink cell is a cell that can perform at least uplink transmission; the downlink cell is a cell that can perform at least downlink transmission.

[0180] Another application example is provided, such as Figure 5 As shown, the communication method includes:

[0181] Step 501: The network device sends configuration information to the terminal;

[0182] The configuration information includes:

[0183] The network device configures a cell index for the terminal, which is associated with at least two cells configured with PUCCH resources or cells that can transmit HARQ feedback.

[0184] The configuration information may be predefined, or pre-configured by the network device or instructed to the terminal; no limitation is made here.

[0185] Step 502: The network device sends the first signaling to the terminal;

[0186] The first signaling is used to indicate the cell activated by the terminal, or the carrier unit performing carrier aggregation, or the carrier unit or cell that can perform uplink transmission.

[0187] Step 503: The terminal determines the cell from which HARQ feedback is transmitted;

[0188] Specifically, the terminal determines the cell from which HARQ feedback is transmitted based on at least one of the following:

[0189] The cell index; based on the association between the cell index and the cells, at least two corresponding cells can be identified;

[0190] The cell that the terminal is activating, or the carrier unit that is performing carrier aggregation, or the carrier unit or cell that can perform uplink transmission.

[0191] Here, the terminal determines the cell associated with the cell index for transmitting PUCCH according to the first signaling and predefined rules. The PUCCH is used by the terminal to transmit HARQ feedback; that is, the cell for transmitting HARQ feedback is determined.

[0192] Alternatively, the terminal may, according to the first signaling, select the cell with the highest sorting or priority among the cells associated with the cell index for transmitting PUCCH; here, the PUCCH is used by the terminal to transmit HARQ feedback, that is, the cell with the highest sorting or priority is selected as the cell for transmitting HARQ feedback according to the first signaling.

[0193] Alternatively, the terminal receives other signaling sent by the network device, which is used to indicate the uplink cell associated with the cell index, and the uplink cell is used to transmit PUCCH; here, the PUCCH is used by the terminal to transmit HARQ feedback, that is, to modify the correspondence between the cell index and the cell through other signaling, so as to modify the cell transmitting HARQ feedback.

[0194] For example, the network device configures N uplink cells for the terminal; the network device configures a certain downlink cell of the terminal with the index I of the cell that can transmit PUCCH or has PUCCH resources.

[0195] The network device instructs the terminal to activate T cells / perform uplink carrier aggregation via the first signaling. The intersection of T cells and N cells is M cells.

[0196] The correspondence between the cell index I and the T cells is predefined. For example, index I corresponds to the I-th cell among the T cells (the T cells are sorted according to a certain cell index); or, the network device indicates or configures which cell among the T cells index I corresponds to through signaling; or the terminal determines the uplink cell for transmitting the HARQ feedback of the downlink cell based on the priority of at least one cell among the T cells corresponding to cell index I.

[0197] Alternatively, the correspondence between the cell index I and the M cells can be predefined. For example, index I corresponds to the I-th cell among the M cells (the M cells are sorted according to a certain cell index); or the network device can indicate or configure which cell among the M cells index I corresponds to through signaling; or the terminal can determine the uplink cell for transmitting the HARQ feedback of the downlink cell based on the priority of at least one cell among the M cells corresponding to cell index I.

[0198] The terminal determines the uplink cell for transmitting the HARQ feedback of the downlink cell based on the correspondence, that is, the terminal transmits the HARQ feedback of the downlink cell on the PUCCH of the uplink cell.

[0199] Another application embodiment is provided, wherein the communication method includes:

[0200] When network equipment is configured for terminals in different active cells, or carrier units that perform carrier aggregation, or cells or carrier units that can perform uplink transmission, it can transmit PUCCH or cells configured with PUCCH resources.

[0201] The terminal determines the cell that can transmit PUCCH based on the activated cell, the carrier unit performing carrier aggregation, or the cell or carrier unit that can perform uplink transmission. The PUCCH is used by the terminal to transmit HARQ feedback.

[0202] For example, the network device configures N uplink cells for the terminal; the network device instructs the terminal via the first signaling to use T carrier units for uplink carrier aggregation or to activate T cells (T<=N).

[0203] When a network device is configured for a terminal's downlink cell in different active cells, or in a carrier unit that performs carrier aggregation, or in a cell or carrier unit that can perform uplink transmission, it can transmit HARQ feedback or a cell configured with PUCCH resources.

[0204] The terminal determines the uplink cell for transmitting the HARQ feedback of the downlink cell based on the information of the T uplink cells corresponding to the carrier units that are activated or undergoing carrier aggregation as indicated by the current first signaling (such as whether PUCCH resources are configured, the priority of each cell, etc.).

[0205] For example, for a given downlink cell, rules can be predefined to indicate how to select the cell for transmitting HARQ feedback; for example, the configuration for the cell transmitting HARQ feedback is as follows:

[0206] If cell 1 and cell 2 are activated, cell 1 is selected to transmit HARQ feedback; if cell 2 and cell 3 are activated, cell 2 is selected to transmit HARQ feedback; if cell 1 and cell 3 are activated, cell 1 is selected to transmit HARQ feedback.

[0207] When applying the application, the cell for transmitting HARQ feedback is determined based on the above predefined rules and the actual situation.
