Description

TECHNICAL FIELD

[0001] The present disclosure relates to the field of communications, and in particular, to a cross-carrier scheduling method and device, and a storage medium. BACKGROUND

[0002] The initial deployment of new generation mobile communication technology usually occurs in areas with high traffic density and high requirements for new services. Then gradually expand the coverage. In the process of gradually deploying new access technologies, the mixed coverage of new technologies and old technologies becomes a necessary requirement for operator networks.

[0003] Even in areas where new technologies have been deployed, it is often necessary to retain earlier technologies and coexist for a considerable period of time to ensure continuous service for old devices that do not support new technologies. 5G (5th Generation Mobile Communication Technology) NR (New Radio) can be deployed in the same spectrum as LTE (Long Term Evolution), so that the total spectrum capacity can be dynamically shared between the two technologies, with higher spectrum utilization. In the case of LTE, NR sharing the primary carrier, the problem of insufficient PDCCH (Physical Downlink Control Channel) resources on the PCell (Primary Cell) and / or PSCell (Primary Secondary Cell) is prone to occur.

[0088] The cross-carrier scheduling method provided by the present disclosure will be introduced first from the base station side.

[0089] In the first scheme, in the case that the target secondary cell cannot schedule the physical shared channel of the primary cell and / or the primary secondary cell, the scheduling carrier carrying the physical downlink control channel PDCCH is switched from the target secondary cell to the associated secondary cell.

[0090] The present embodiment provides a cross-carrier scheduling method, which is described with reference toFigure 1 As shown in Figure 1 is a cross-carrier scheduling method flow chart according to an embodiment, which can be used for a network side device including but not limited to a base station, and the method can include the following steps:

[0091] In step 101, an associated secondary cell associated with a target secondary cell is configured.

[0092] In the embodiments of the present disclosure, the target secondary cell can be an sSCell, which refers to a secondary cell configured to schedule a physical shared channel of a primary cell and / or a primary secondary cell, wherein the physical shared channel includes but is not limited to a PDSCH (Physical Downlink Shared Channel) and / or a PUSCH (Physical Uplink Shared Channel).

[0093] In step 102, in response to determining that the physical shared channel of the primary cell and / or the primary secondary cell cannot be scheduled through the target secondary cell, a scheduling carrier carrying a physical downlink control channel PDCCH is switched from the target secondary cell to the associated secondary cell.

[0094] The PDCCH is used to schedule the physical shared channel of the primary cell and / or the primary secondary cell.

[0095] In the above embodiments, the network side device can be configured to configure an associated secondary cell associated with a target secondary cell, and in the case that the physical shared channel of the primary cell and / or the primary secondary cell cannot be scheduled through the target secondary cell, the scheduling carrier carrying the physical downlink control channel PDCCH is switched to the associated secondary cell, the PDCCH is used to schedule the physical shared channel of the primary cell and / or the primary secondary cell, the fast switching of the scheduling carrier is realized, the problem of insufficient PDCCH resources of the primary cell and / or the primary secondary cell is solved, and the system resource utilization rate is improved.

[0096] In some optional embodiments, referring to Figure 2 As shown in Figure 2 is a cross-carrier scheduling method flow chart according to an embodiment, which can be used for a network side device including but not limited to a base station, and the method can include the following steps:

[0097] In step 201, an associated secondary cell associated with a target secondary cell is configured.

[0098] The target secondary cell is a secondary cell configured to schedule a physical shared channel of a primary cell and / or a primary secondary cell.

[0099] In step 202, the terminal is sent configuration information of the associated secondary cell.

[0100] In the embodiment of the present disclosure, after the associated secondary cell associated with the target secondary cell is configured, the network side device can send the terminal the configuration information of the associated secondary cell.

[0101] In the embodiment of the present disclosure, the configuration information of the associated secondary cell can include but is not limited to at least one of the following: control resource set of the associated secondary cell; and / or, search space of the associated secondary cell; and / or, index value of the primary cell and / or primary secondary cell in the scheduling information of the associated secondary cell.

[0102] In the embodiment of the present disclosure, the terminal side can determine that the scheduling carrier of the associated secondary cell schedules the physical shared channel of the primary cell and / or the primary secondary cell based on the index value of the primary cell and / or the primary secondary cell in the scheduling information of the associated secondary cell. In addition, the terminal side can determine the resource location of the PDCCH on the scheduling carrier after the network side device switches the scheduling carrier to the associated secondary cell based on at least one of the CORESET (Control Resource Set) of the associated secondary cell and the search space of the associated secondary cell, so as to demodulate the PDCCH to achieve the purpose of scheduling the physical shared channel of the primary cell and / or the primary secondary cell.

[0103] In step 203, in response to determining that the physical shared channel of the primary cell and / or the primary secondary cell cannot be scheduled through the target secondary cell, the scheduling carrier carrying the physical downlink control channel PDCCH is switched from the target secondary cell to the associated secondary cell.

[0104] In the embodiment, the PDCCH is used to schedule the physical shared channel of the primary cell and / or the primary secondary cell.

[0105] In the above embodiment, after the network side device configures the associated secondary cell associated with the target secondary cell, the network side device can send the terminal the configuration information of the associated secondary cell, so as to subsequently determine that the physical shared channel of the primary cell and / or the primary secondary cell cannot be scheduled through the target secondary cell, and perform scheduling carrier switching to switch the scheduling carrier from the target secondary cell to the associated secondary cell. The problem of insufficient PDCCH resources of the primary cell and / or the primary secondary cell is solved, and the system resource utilization rate is improved by better adapting to changes in load and link quality.

[0106] In one possible implementation, the network side device can determine that the physical shared channel of the primary cell and / or the primary secondary cell cannot be scheduled through the target secondary cell in a case where the target secondary cell is determined to be deactivated.

[0107] In another possible implementation, the network-side device may determine that it is impossible to schedule the physical shared channel of the primary cell and / or the primary and secondary cells through the target secondary cell upon receiving the Radio Link Failure (RLF) indication information sent by the terminal.

[0108] In another possible implementation, the network-side device may determine that it is impossible to schedule the physical shared channel of the primary cell and / or the primary and secondary cells through the target secondary cell if it determines that the target secondary cell is deactivated and receives the target secondary cell RLF indication information sent by the terminal.

[0109] In the above embodiments, the network-side equipment can determine, based on different situations, the physical shared channels of the primary cell and / or primary and secondary cells that cannot be scheduled through the target secondary cell, thereby performing carrier switching, which is simple to implement and highly available.

[0110] The second approach involves switching the scheduling carrier carrying the Physical Downlink Control Channel (PDCCH) from the target secondary cell to the primary cell and / or the primary and / or secondary cells when it is impossible to schedule the physical shared channel between the primary and / or secondary cells through the target secondary cell.

[0111] This disclosure provides a cross-carrier scheduling method, referring to... Figure 3 As shown, Figure 3 This is a flowchart illustrating a cross-carrier scheduling method according to an embodiment, which can be used in network-side devices, including but not limited to base stations. The method may include the following steps:

[0112] In step 301, in response to determining that the physical shared channel of the primary cell and / or primary and secondary cells cannot be scheduled through the target secondary cell, an associated secondary cell that is not configured with the target secondary cell is determined.

[0113] The target secondary cell is a secondary cell configured to schedule the physical shared channel between the primary cell and / or the primary and secondary cells.

[0114] In one possible implementation, the network-side device can determine that the primary cell and / or the physical shared channel between the primary and secondary cells cannot be scheduled through the target secondary cell if the target secondary cell is deactivated.

[0115] In another possible implementation, the network-side device may determine, upon receiving the target secondary cell RLF indication information sent by the terminal, that it is impossible to schedule the physical shared channel of the primary cell and / or the primary and secondary cells through the target secondary cell.

[0116] In another possible implementation, the network-side device can determine that the primary cell and / or the primary secondary cell cannot be scheduled by the target secondary cell through the target secondary cell in a case where it is determined that the target secondary cell is deactivated and the target secondary cell RLF indication information sent by the terminal is received.

[0117] In step 302, the scheduling carrier carrying a physical downlink control channel (PDCCH) is switched from the target secondary cell to the primary cell and / or the primary secondary cell.

[0118] The PDCCH is used to schedule a physical shared channel of the primary cell and / or the primary secondary cell.

[0119] In the above embodiment, the network-side device switches the scheduling carrier carrying a physical downlink control channel (PDCCH) from the target secondary cell to the primary cell and / or the primary secondary cell in a case where the primary cell and / or the primary secondary cell cannot be scheduled by the target secondary cell through the target secondary cell and no associated secondary cell associated with the target secondary cell is configured, the PDCCH is used to schedule a physical shared channel of the primary cell and / or the primary secondary cell, the fast switching of the scheduling carrier is implemented, the primary cell and / or the primary secondary cell is self-scheduled, and the system resource utilization rate can be improved by better adapting to the changes in load and link quality.

[0120] In summary, in a case where the primary cell and / or the primary secondary cell cannot be scheduled by the target secondary cell through the target secondary cell, different scheduling carrier switching manners are adopted according to whether an associated secondary cell is configured. When an associated secondary cell associated with the target secondary cell is configured, the scheduling carrier is switched from the target secondary cell to the associated secondary cell, and when no associated secondary cell associated with the target secondary cell is configured, the scheduling carrier is switched from the target secondary cell to the primary cell and / or the primary secondary cell. In this way, the problem of insufficient PDCCH resources of the primary cell and / or the primary secondary cell is solved, the system resource utilization rate can be improved by better adapting to the changes in load and link quality. Next, the cross-carrier scheduling method provided by the present disclosure is introduced from the terminal side.

[0121] In a first scheme, configuration information of an associated secondary cell associated with a target secondary cell is received, and it is determined that a network-side device switches a scheduling carrier carrying a physical downlink control channel (PDCCH) from the target secondary cell to the associated secondary cell.

[0122] The present embodiment provides a cross-carrier scheduling method, as shown in Figure 4 Figure 4 is a flowchart of a cross-carrier scheduling method according to an embodiment, which can be used for a terminal. The method can include the following steps:

[0123] In step 401, configuration information of an associated secondary cell associated with a target secondary cell sent by a network-side device is received.​

[0124] The target secondary cell is a secondary cell configured to schedule a physical shared channel of the primary cell and / or the primary secondary cell.

[0125] In step 402, it is determined that the network side device cannot schedule a physical shared channel of the primary cell and / or the primary secondary cell through the target secondary cell.

[0126] In one possible implementation, the terminal determines that the network side device cannot schedule a physical shared channel of the primary cell and / or the primary secondary cell through the target secondary cell in a case where it is determined that the target secondary cell is deactivated.

[0127] In another possible implementation, the terminal determines that the network side device cannot schedule a physical shared channel of the primary cell and / or the primary secondary cell through the target secondary cell in a case where the target secondary cell RLF indication information is sent to the network side device.

[0128] In step 403, based on the configuration information of the associated secondary cell, it is determined that the network side device will switch a scheduling carrier carrying a physical downlink control channel (PDCCH) from the target secondary cell to the associated secondary cell.

[0129] The PDCCH is used to schedule a physical shared channel of the primary cell and / or the primary secondary cell.

[0130] In the above embodiment, the terminal can determine that the network side device will switch a scheduling carrier from the target cell to the associated secondary cell based on the configuration information of the associated secondary cell sent by the network side device in a case where it is determined that the network side device cannot schedule a physical shared channel of the primary cell and / or the primary secondary cell through the target secondary cell. The fast switching of the scheduling carrier is realized, the problem of insufficient PDCCH resources of the primary cell and / or the primary secondary cell is solved, and the system resource utilization rate is improved.

[0131] In some optional embodiments, the configuration information of the associated secondary cell includes at least one of the following: a control resource set of the associated secondary cell; a search space of the associated secondary cell; and / or an index value in scheduling information of the primary cell and / or the primary secondary cell in the associated secondary cell.

[0132] In the embodiments of the present disclosure, after the terminal switches to the associated secondary cell, the terminal can determine the physical shared channel of the primary cell and / or the primary secondary cell scheduled by the scheduling carrier based on the index value of the primary cell and / or the primary secondary cell in the scheduling information of the associated secondary cell. The terminal can also determine the position of the PDCCH carried on the scheduling carrier based on at least one of the control resource set of the associated secondary cell and the search space of the associated secondary cell, demodulate the PDCCH, and achieve the purpose of scheduling the physical shared channel of the primary cell and / or the primary secondary cell based on the demodulated PDCCH.

[0133] In the second scheme, the configuration information of the associated secondary cell not received is determined, and it is determined that the network side device switches the scheduling carrier carrying the physical downlink control channel PDCCH from the target secondary cell to the primary cell and / or the primary secondary cell.

[0134] The embodiments of the present disclosure provide a cross-carrier scheduling method, as shown in Figure 5 Figure 5 is a flowchart of a cross-carrier scheduling method according to an embodiment, which can be used for a terminal. The method can include the following steps:

[0135] In step 501, it is determined that the network side device cannot schedule the physical shared channel of the primary cell and / or the primary secondary cell through the target secondary cell.

[0136] In one possible implementation, the terminal determines that the network side device cannot schedule the physical shared channel of the primary cell and / or the primary secondary cell through the target secondary cell in a case where it is determined that the target secondary cell is deactivated.

[0137] In another possible implementation, the terminal determines that the network side device cannot schedule the physical shared channel of the primary cell and / or the primary secondary cell through the target secondary cell in a case where it sends the RLF indication information of the target secondary cell to the network side device.

[0138] In another possible implementation, the network side device can determine that it cannot schedule the physical shared channel of the primary cell and / or the primary secondary cell through the target secondary cell in a case where it determines that the target secondary cell is deactivated and receives the RLF indication information of the target secondary cell sent by the terminal.

[0139] In step 502, in response to determining that the configuration information of the associated secondary cell related to the target secondary cell sent by the network side device is not received, it is determined that the network side device switches the scheduling carrier carrying the physical downlink control channel PDCCH from the target secondary cell to the primary cell and / or the primary secondary cell.

[0140] ​In the embodiments of the present disclosure, if the terminal does not receive the configuration information of the associated secondary cell associated with the target secondary cell sent by the network side device, the terminal can determine that the network side device does not configure the target secondary cell, and can determine that the network side device will switch the scheduling carrier from the target secondary cell to the primary cell and / or the primary secondary cell. That is, subsequent self-scheduling will be performed by the primary cell and / or the primary secondary cell.

[0141] In the above embodiments, the fast switching of the scheduling carrier is realized, the self-scheduling of the primary cell and / or the primary secondary cell can be performed in the case that the network side device cannot schedule the physical shared channel of the primary cell and / or the primary secondary cell through the target secondary cell, and the associated secondary cell associated with the target secondary cell is not configured, and the system resource utilization can be improved by better adapting to the changes of load and link quality.

[0142] In some optional embodiments, referring to FIG. 1, Figure 6 Figure 6 FIG. 1 is a flow chart of a cross-carrier scheduling method according to an embodiment, the method can include the following steps:

[0143] In step 601, the network side device configures an associated secondary cell associated with a target secondary cell.

[0144] The target secondary cell is a secondary cell configured to schedule the physical shared channel of the primary cell and / or the primary secondary cell.

[0145] In step 602, the network side device sends the configuration information of the associated secondary cell to the terminal.

[0146] The configuration information of the associated secondary cell includes at least one of the following: a control resource set of the associated secondary cell; a search space of the associated secondary cell; and / or an index value in the scheduling information of the primary cell and / or the primary secondary cell in the associated secondary cell.

[0147] In step 603, the network side device switches the scheduling carrier carrying the physical downlink control channel (PDCCH) from the target secondary cell to the associated secondary cell in response to determining that the physical shared channel of the primary cell and / or the primary secondary cell cannot be scheduled through the target secondary cell.

[0148] The PDCCH is used to schedule the physical shared channel of the primary cell and / or the primary secondary cell.

[0149] ​The network-side device determines that the network-side device cannot schedule a physical shared channel of the primary cell and / or the primary secondary cell through the target secondary cell in response to determining that the target secondary cell is deactivated. Alternatively, the network-side device determines that the network-side device cannot schedule a physical shared channel of the primary cell and / or the primary secondary cell through the target secondary cell in response to receiving the target secondary cell RLF indication information sent by the terminal. Alternatively, the network-side device determines that the network-side device cannot schedule a physical shared channel of the primary cell and / or the primary secondary cell through the target secondary cell in the case that the network-side device determines that the target secondary cell is deactivated and receives the target secondary cell RLF indication information sent by the terminal.

[0150] In step 604, the terminal determines that the network-side device cannot schedule a physical shared channel of the primary cell and / or the primary secondary cell through the target secondary cell.

[0151] In step 605, the terminal determines that the network-side device switches the scheduling carrier from the target secondary cell to the associated secondary cell based on the configuration information of the associated secondary cell.

[0152] In the above embodiment, the network-side device configures an associated secondary cell associated with the target secondary cell, and switches a scheduling carrier carrying a physical downlink control channel (PDCCH) to the associated secondary cell in the case that the network-side device cannot schedule a physical shared channel of the primary cell and / or the primary secondary cell through the target secondary cell, the PDCCH being used to schedule a physical shared channel of the primary cell and / or the primary secondary cell. The above method can realize fast switching of the scheduling carrier, solve the problem of insufficient PDCCH resources of the primary cell and / or the primary secondary cell, and better adapt to changes in load and link quality, thereby improving system resource utilization.

[0153] In some optional embodiments, referring to Figure 7 Figure 7 is a flowchart of a cross-carrier scheduling method according to an embodiment. The method can include the following steps:

[0154] In step 701, the network-side device determines that no associated secondary cell associated with the target secondary cell is configured in response to determining that the network-side device cannot schedule a physical shared channel of the primary cell and / or the primary secondary cell through the target secondary cell.

[0155] ​The network-side device determines that the network-side device cannot schedule a physical shared channel of the primary cell and / or the primary secondary cell through the target secondary cell in response to determining that the target secondary cell is deactivated. Alternatively, the network-side device determines that the network-side device cannot schedule a physical shared channel of the primary cell and / or the primary secondary cell through the target secondary cell in response to receiving the target secondary cell RLF indication information sent by the terminal. Alternatively, the network-side device determines that the network-side device cannot schedule a physical shared channel of the primary cell and / or the primary secondary cell through the target secondary cell in the case that the network-side device determines that the target secondary cell is deactivated and receives the target secondary cell RLF indication information sent by the terminal.

[0156] In step 702, the network-side device switches a scheduling carrier carrying a physical downlink control channel (PDCCH) from the target secondary cell to the primary cell and / or the primary secondary cell.

[0157] The PDCCH is used to schedule a physical shared channel of the primary cell and / or the primary secondary cell.

[0158] In step 703, the terminal determines that the network-side device cannot schedule a physical shared channel of the primary cell and / or the primary secondary cell through the target secondary cell.

[0159] In step 704, the terminal determines that the network-side device switches the scheduling carrier from the target secondary cell to the primary cell and / or the primary secondary cell in response to determining that the configuration information of an associated secondary cell associated with the target secondary cell sent by the network-side device is not received.

[0160] In the above embodiment, the network-side device can switch a scheduling carrier carrying a physical downlink control channel (PDCCH) from the target secondary cell to the primary cell and / or the primary secondary cell in the case that the network-side device cannot schedule a physical shared channel of the primary cell and / or the primary secondary cell through the target secondary cell and an associated secondary cell associated with the target secondary cell is not configured, the PDCCH is used to schedule a physical shared channel of the primary cell and / or the primary secondary cell, the scheduling carrier is switched quickly, the primary cell and / or the primary secondary cell is self-scheduled, the system resource utilization rate is improved, and the load and link quality can be better adapted.

[0161] In summary, in the case that it is determined that the target secondary cell cannot schedule the physical shared channel of the primary cell and / or the primary secondary cell, different scheduling carrier switching manners are taken according to whether the associated secondary cell is configured. When the associated secondary cell associated with the target secondary cell is configured, the scheduling carrier is switched from the target secondary cell to the associated secondary cell, and when the associated secondary cell associated with the target secondary cell is not configured, the scheduling carrier is switched from the target secondary cell to the primary cell and / or the primary secondary cell. In this way, the problem of insufficient PDCCH resources of the primary cell and / or the primary secondary cell is solved, and the system resource utilization rate is improved by better adapting to the changes of load and link quality.
