Description

[0001] This application is a divisional application of application number 202180000759.8, filed on March 18, 2021, entitled "Carrier scheduling method and apparatus, scheduling mode switching method and apparatus". Technical Field

[0002] This disclosure relates to the field of wireless communication technology, and in particular to a carrier scheduling method and apparatus, and a scheduling mode switching method and apparatus. Background Technology

[0003] Currently, 5G (5th Generation) NR (New Radio) can be deployed in the same spectrum as LTE (Long Term Evolution), allowing for dynamic sharing of total spectrum capacity between the two technologies and resulting in high spectrum utilization. However, when LTE and NR share the primary carrier, insufficient PDCCH (Physical Downlink Control Channel) resources on the PCell (Primary Cell) / PSCell (Primary Secondary Cell) can easily occur.

[0004] To address the issue of insufficient PDCCH resources on PCell / PSCell in the aforementioned scenarios, 3GPP (Third Generation Partnership Project) Rel-17 proposed a candidate scheme: scheduling PCell / PSCell using SCell (Secondary Cell) and scheduling two PDSCH (Physical Downlink Shared Channel) channels using DCI (Downlink Control Information) signaling.

[0005] However, the current 5G NR standard can only support one DCI signaling to schedule one PDSCH / PUSCH on one cell, that is, there is a one-to-one correspondence between the scheduling carrier and the scheduled carrier. In this way, the signaling overhead is relatively large. Summary of the Invention

[0006] The first aspect of this disclosure provides a carrier scheduling method, comprising: sending a configuration message of a scheduled carrier group to a user equipment (UE), the configuration message indicating one or more scheduled carrier groups and the scheduled carriers contained in each scheduled carrier group; and sending a first downlink control information (DCI) to the UE, the first DCI being used to determine: a scheduled carrier group, wherein each scheduled carrier in the same scheduled carrier group corresponds to a scheduling carrier.

[0007] Optionally, the first DCI is further configured to determine: a scheduling carrier for scheduling the scheduled carrier group.

[0008] Optionally, the configuration message of the scheduled carrier group includes the number of one or more scheduled carrier groups, and the number of the scheduled carriers contained in each scheduled carrier group.

[0009] Optionally, sending the configuration message of the scheduled carrier group to the UE includes: sending the configuration message of the scheduled carrier group to the UE via a first Radio Resource Control (RRC) signaling.

[0010] Optionally, the scheduling mode of the UE includes a joint scheduling mode and an independent scheduling mode, and the first DCI is further used to determine that the scheduling mode corresponding to the scheduled carrier group is a joint scheduling mode.

[0011] The second aspect of this disclosure provides another carrier scheduling method, comprising: receiving a configuration message of a scheduled carrier group sent by a network-side device, the configuration message indicating one or more scheduled carrier groups and the scheduled carriers contained in each scheduled carrier group; and receiving a first downlink control information (DCI) sent by the network-side device, the first DCI being used to determine: a scheduled carrier group, wherein each scheduled carrier in the same scheduled carrier group corresponds to a scheduling carrier.

[0012] A third aspect of this disclosure provides a carrier scheduling apparatus, comprising: a transmitting module, configured to transmit a configuration message of a scheduled carrier group to a UE, the configuration message indicating one or more scheduled carrier groups and the scheduled carriers contained in each scheduled carrier group; and transmitting first downlink control information (DCI) to the UE, the first DCI being configured to determine: a scheduled carrier group, wherein each scheduled carrier within the same scheduled carrier group corresponds to a scheduling carrier.

[0013] The fourth aspect of this disclosure provides another carrier scheduling apparatus, comprising: a receiving module, configured to receive a configuration message of a scheduled carrier group sent by a network-side device, the configuration message indicating one or more scheduled carrier groups and the scheduled carriers contained in each scheduled carrier group; and receiving first downlink control information (DCI) sent by the network-side device, the first DCI being used to determine: a scheduled carrier group, wherein each scheduled carrier in the same scheduled carrier group corresponds to a scheduling carrier.

[0014] A fifth aspect of this disclosure provides a communication device, including: a transceiver; a memory; and a processor, respectively connected to the transceiver and the memory, configured to control the wireless signal transmission and reception of the transceiver by executing computer-executable instructions on the memory, and capable of implementing the carrier scheduling method proposed in the first aspect of this disclosure, or implementing the carrier scheduling method proposed in the second aspect of this disclosure.

[0015] A sixth aspect of this disclosure provides a computer storage medium storing computer-executable instructions; when executed by a processor, the computer-executable instructions can implement the carrier scheduling method proposed in the first aspect of this disclosure, or implement the carrier scheduling method proposed in the second aspect of this disclosure.

[0016] The carrier scheduling method and apparatus provided in this disclosure send a configuration message of a scheduled carrier group to the UE via a network-side device, and also send the association relationship between the scheduled carrier group and the corresponding scheduling carrier to the UE. The configuration message of the scheduled carrier group and the association relationship are used to instruct the UE to determine the scheduled carrier group and the scheduling carrier. Therefore, one scheduling carrier can correspond to a group of scheduled carriers, thereby enabling one DCI signaling to schedule multiple PDSCH / PUSCHs on multiple cells, saving signaling overhead.

Depending on the context, the words “if” and “suppose” as used herein may be interpreted as “when”, “when”, or “in response to a determination”.

[0022] Embodiments of this disclosure are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this disclosure, and should not be construed as limiting this disclosure.

[0023] With the continuous emergence of new-generation internet applications such as AR (Augmented Reality), VR (Virtual Reality), and vehicle-to-vehicle communication, higher demands are being placed on wireless communication technology, driving its continuous evolution to meet the needs of these new applications. Currently, cellular mobile communication technology is in the evolutionary stage of a new generation of wireless communication technology, one important feature of which is the flexible configuration supporting multiple service types.

[0024] Different service types have different transmission requirements for wireless communication technologies. For example, eMBB (enhanced Mobile Broadband) services focus on high bandwidth and high speed, URLLC (Ultra Reliable Low Latency Communication) services focus on relatively high reliability and relatively low latency, and mMTC (massive Machine Type Communication) services focus on a massive number of connections. Therefore, next-generation wireless communication systems need flexible and configurable designs to support the transmission requirements of various service types.

[0025] In the research of wireless communication technology, satellite communication is considered an important aspect of the future development of wireless communication technology. Satellite communication refers to communication conducted by ground-based radio communication equipment using satellites as relay nodes. A satellite communication system can consist of a satellite component and a ground component. Satellite communication has the following characteristics: First, it has a large communication range; communication can be conducted between any two points within the coverage area of ​​the radio waves emitted by the satellite. Second, it is not easily affected by land-based disasters, meaning that satellite communication has high reliability.

[0026] Satellite communication can serve as an important supplement to terrestrial cellular communication systems, offering the following advantages: First, extended coverage: For areas that cannot be covered by terrestrial cellular communication systems or where the cost of coverage is relatively high, such as oceans, deserts, and remote mountainous areas, satellite communication can solve the communication problems in these areas at a relatively low cost. Second, emergency communications: In extreme situations such as disasters like earthquakes that render terrestrial cellular communication infrastructure unavailable, satellite communications can quickly establish communication connections and improve rescue efficiency. Third, it provides industry applications: for example, for time-sensitive services that require long-distance transmission, satellite communication can be used to reduce the latency of service transmission.

[0027] The initial deployment of next-generation mobile communication technology, 5G NR, typically occurs in areas with relatively high traffic density and high demand for new services, followed by a gradual expansion of coverage. During this gradual deployment, the mixed coverage of new and old technologies becomes an inevitable requirement for operator networks. Even in areas where new technologies have been deployed, older technologies must usually be retained, and both new and old technologies must coexist for a considerable period to ensure continued service for older equipment that does not support the new technologies.

[0028] Currently, 5G NR can be deployed on the same spectrum as LTE, allowing for dynamic sharing of total spectrum capacity between the two technologies and resulting in high spectrum utilization. However, when LTE and NR share the primary carrier, insufficient PDCCH resources on the PCell / PSCell can easily occur.

[0029] To address the issue of insufficient PDCCH resources on PCell / PSCell in the aforementioned scenarios, the 3GPP Rel-17 project proposed a candidate scheme for scheduling PCell / PSCell using SCell, and scheduling two PDSCHs using one DCI signaling.

[0030] However, the current 5G NR standard does not yet support one DCI signaling to schedule two PDSCH / PUSCH (Physical Uplink Shared Channel) on two cells.

[0031] To address the aforementioned issues, this disclosure provides a carrier scheduling method and apparatus, and a scheduling mode switching method and apparatus.

[0032] Figure 1 This is a schematic flowchart illustrating a carrier scheduling method provided in an embodiment of the present disclosure. This carrier scheduling method can be applied to network-side devices.

[0033] In this context, network-side equipment is exemplified by base stations. A base station can include multiple cells that provide services to UEs (User Equipment). Depending on the specific application, each cell can contain multiple TRPs (Transmitting Receiving Points), or it can be a device in the access network that communicates with wireless terminal devices through one or more sectors on the air interface, or other names. For example, the base station involved in the embodiments of this disclosure can be a BTS (Base Transceiver Station) in GSM (Global System for Mobile communications) or CDMA (Code Division Multiple Access), or a base station (NodeB) in WCDMA (Wide-band Code Division Multiple Access), or an evolved Node B (eNB or e-NodeB) in LTE (long term evolution) system, or a 5G base station (gNB) in the 5G network architecture (next generation system), or a HeNB (Home evolved Node B), relay node, femto, pico, etc., and is not limited in the embodiments of this disclosure.

[0034] The UE can be a device that provides voice and / or data connectivity to a user, a handheld device with wireless connectivity, or other processing devices connected to a wireless modem. The name of the UE may vary in different systems. A wireless UE can communicate with one or more CNs (Core Networks) via a RAN (Radio Access Network). A wireless UE can be a mobile terminal device, such as a mobile phone (or "cellular" phone), or a computer with a mobile terminal device, for example, a portable, pocket-sized, handheld, computer-embedded, or vehicle-mounted mobile device, which exchanges voice and / or data with the radio access network.

[0035] For example, a UE can be a PCS (Personal Communication Service) phone, a cordless phone, a SIP (Session Initiated Protocol) phone, a WLL (Wireless Local Loop) station, a PDA (Personal Digital Assistant), or other similar devices. A wireless UE can also be referred to as a system, subscriber unit, subscriber station, mobile station, mobile station, remote station, access point, remote terminal, access terminal, user terminal, user agent, or user device; however, this disclosure does not limit the terminology used in this embodiment.

[0036] like Figure 1 As shown, the carrier scheduling method may include the following steps: Step 101: Send the configuration message of the scheduled carrier group to the UE.

[0037] In this embodiment of the disclosure, the scheduled carrier group may include one or more scheduled carriers, wherein a scheduled carrier refers to a carrier that transmits PDSCH or PUSCH.

[0038] In one possible implementation of this disclosure, the configuration message for a scheduled carrier group may include one or more scheduled carrier groups, and the scheduled carriers contained in each scheduled carrier group. Optionally, the configuration message for a scheduled carrier group may further include the number of each scheduled carrier group, and the number of the scheduled carriers contained in each scheduled carrier group.

[0039] In this embodiment of the disclosure, the network-side device can send a configuration message of the scheduled carrier group to the UE.

[0040] Step 102: Send the association relationship between the scheduled carrier group and the corresponding scheduled carrier to the UE. The configuration message of the scheduled carrier group and the association relationship are used to instruct the UE to determine the scheduled carrier group and the scheduled carrier.

[0041] In this embodiment of the disclosure, the scheduling carrier refers to the carrier that transmits the PDCCH.

[0042] In this embodiment of the disclosure, each scheduled carrier in the same scheduled carrier group corresponds to one scheduled carrier.

[0043] In this embodiment, the network-side device can send the association relationship between the scheduled carrier group and the corresponding scheduling carrier to the UE. Correspondingly, after receiving the configuration message of the scheduled carrier group and the association relationship between the scheduled carrier group and the corresponding scheduling carrier, the UE can determine the scheduled carrier group and the corresponding scheduling carrier based on the configuration message and the association relationship. Thus, one scheduling carrier can correspond to a group of scheduled carriers, thereby enabling one DCI signaling to schedule multiple PDSCH / PUSCHs on multiple cells, saving signaling overhead.

[0044] In one possible implementation of this disclosure, when the configuration message of the scheduled carrier includes a scheduled carrier group, the UE can determine the scheduled carrier group to which each scheduled carrier belongs based on the configuration message of the scheduled carrier group, and determine the scheduling carrier corresponding to the scheduled carrier group based on the association between the scheduled carrier group and its corresponding scheduling carrier.

[0045] In one possible implementation of this disclosure, when the configuration message of the scheduled carrier includes multiple scheduled carrier groups, the UE can determine a target scheduled carrier and determine the scheduled carrier group corresponding to the target scheduled carrier based on the above-mentioned association relationship.

[0046] It should be noted that the above-described example of step 102 being executed after step 101 is only an example of this disclosure, but this disclosure is not limited thereto. For example, step 102 may also be executed before step 101, or step 102 may be executed in parallel with step 101, without any limitation.

[0047] The carrier scheduling method of this disclosure involves sending a configuration message of a scheduled carrier group to the UE via a network-side device, and sending the UE an association relationship between the scheduled carrier group and the corresponding scheduling carrier. The configuration message and association relationship of the scheduled carrier group are used to instruct the UE to determine the scheduled carrier group and the scheduling carrier. Therefore, one scheduling carrier can correspond to a group of scheduled carriers, thereby enabling a single DCI signaling to schedule multiple PDSCH / PUSCHs on multiple cells, saving signaling overhead.

[0048] This disclosure provides another carrier scheduling method. Figure 2 This is a flowchart illustrating another carrier scheduling method provided in an embodiment of this disclosure. This carrier scheduling method can be applied to network-side devices. The carrier scheduling method can be executed alone, or it can be executed in conjunction with any embodiment of this disclosure or possible implementations within those embodiments, or it can be executed in conjunction with any technical solution in related technologies.

[0049] like Figure 2 As shown, the carrier scheduling method may include the following steps: Step 201: Send a configuration message for the scheduled carrier group to the UE, wherein the configuration message for the scheduled carrier group includes one or more scheduled carrier groups.

[0050] In the embodiments of this disclosure, step 201 can be implemented in any of the ways described in the various embodiments of this disclosure. The embodiments of this disclosure do not limit this and will not elaborate further.

[0051] In one possible implementation of the embodiments of this disclosure, the network-side device can send a configuration message of the scheduled carrier group to the UE through RRC signaling, referred to in this disclosure as the first RRC (Radio Resource Control) signaling.

[0052] Step 202: Send the association relationship between the scheduled carrier group and the corresponding scheduled carrier to the UE. The configuration message of the scheduled carrier group and the association relationship are used to instruct the UE to determine the scheduled carrier group and the scheduled carrier.

[0053] In the embodiments of this disclosure, step 202 can be implemented in any of the various embodiments of this disclosure. This disclosure does not limit this and will not elaborate further.

[0054] Step 203: Send indication information to the UE, wherein the indication information is used to indicate to the UE the number of the scheduled carrier corresponding to each scheduled carrier group.

[0055] In this embodiment of the disclosure, the network-side device can send indication information to the UE, wherein the indication information is used to indicate to the UE the number of the scheduling carrier corresponding to each scheduled carrier group, so that after receiving the indication information, the UE can determine the scheduling carrier according to the number of the scheduling carrier corresponding to the scheduled carrier group, and determine the scheduled carrier group corresponding to the scheduling carrier according to the above-mentioned association relationship.

[0056] In one possible implementation of this application, the network-side device can send indication information to the UE via MAC CE (Medium Access Control-Control Element) signaling, referred to as the first MACCE signaling in this disclosure.

[0057] As one possible implementation, when the configuration message of a scheduled carrier group includes a scheduled carrier group, the network-side device can configure the number of the scheduled carrier corresponding to the scheduled carrier group through the first MAC CE signaling. Thus, after receiving the first MAC CE signaling, the UE can determine the scheduled carrier based on the number of the scheduled carrier corresponding to the scheduled carrier group, and determine the scheduled carrier group corresponding to the scheduled carrier based on the above-mentioned association.

[0058] As another possible implementation, when the configuration message of the scheduled carrier group includes multiple scheduled carrier groups, the network-side device can indicate the number of the scheduled carrier corresponding to one of the multiple scheduled carrier groups through the first MAC CE signaling, which is denoted as the number of the target scheduled carrier in this disclosure. Thus, after receiving the first MAC CE signaling, the UE can determine the target scheduled carrier based on the number of the target scheduled carrier and determine the scheduled carrier group corresponding to the target scheduled carrier based on the above-mentioned correlation.

[0059] In another possible implementation of the embodiments of this disclosure, the network-side device can send indication information to the UE through the second RRC signaling and the second MAC CE signaling.

[0060] As one possible implementation, when the configuration message of a scheduled carrier group includes a scheduled carrier group, the network-side device can configure the number of the scheduled carrier corresponding to the scheduled carrier group through RRC signaling. Thus, after receiving the RRC signaling, the UE can determine the scheduled carrier based on the number of the scheduled carrier corresponding to the scheduled carrier group, and determine the scheduled carrier group corresponding to the scheduled carrier based on the above-mentioned association.

[0061] As another possible implementation, when the configuration message of a scheduled carrier group includes multiple scheduled carrier groups, the network-side device can configure the number of the scheduled carrier corresponding to each scheduled carrier group through the second RRC signaling, and indicate the number of the scheduled carrier corresponding to one of the multiple scheduled carrier groups through the second MAC CE signaling. In this disclosure, this number is referred to as the target scheduled carrier number. Thus, after receiving the second MAC CE signaling, the UE can determine the target scheduled carrier based on the target scheduled carrier number, and determine the scheduled carrier group corresponding to the target scheduled carrier based on the above-mentioned correlation.

[0062] In another possible implementation of the embodiments of this disclosure, the network-side device can send indication information to the UE via the first DCI signaling.

[0063] As one possible implementation, when the configuration message of a scheduled carrier group includes a scheduled carrier group, the network-side device can configure the number of the scheduled carrier corresponding to the scheduled carrier group through the first DCI signaling. Thus, after receiving the first DCI signaling, the UE can determine the scheduled carrier based on the number of the scheduled carrier corresponding to the scheduled carrier group, and determine the scheduled carrier group corresponding to the scheduled carrier based on the above-mentioned association.

[0064] As another possible implementation, when the configuration message of the scheduled carrier group includes multiple scheduled carrier groups, the network-side device can indicate the number of the scheduled carrier corresponding to one of the multiple scheduled carrier groups through the first DCI signaling, which is denoted as the number of the target scheduled carrier in this disclosure. Thus, after receiving the first DCI signaling, the UE can determine the target scheduled carrier based on the number of the target scheduled carrier and determine the scheduled carrier group corresponding to the target scheduled carrier based on the above-mentioned correlation.

[0065] As an example, the network-side device can configure the number of the scheduling carrier corresponding to each scheduled carrier group through RRC signaling, and indicate the number of the scheduling carrier corresponding to one of the multiple scheduled carrier groups through the first DCI signaling. In this disclosure, this number is referred to as the target scheduling carrier number. Thus, after receiving the first DCI signaling, the UE can determine the target scheduling carrier based on the target scheduling carrier number, and determine the scheduled carrier group corresponding to the target scheduling carrier based on the above-mentioned correlation.

[0066] Therefore, network-side devices can send indication messages in multiple ways, which can improve the flexibility and applicability of this method.

[0067] It should be noted that the execution order of steps 201, 202 and 203 is not limited in the embodiments of this disclosure. The above is only an example of executing steps 201 to 203 in sequence. However, this disclosure is not limited to this. For example, steps 201, 203 and 202 can be executed in sequence, or steps 202, 201 and 203 can be executed in sequence, or steps 201 to 203 can be executed in parallel, etc.

[0068] The carrier scheduling method of this disclosure involves sending a configuration message of a scheduled carrier group to the UE via a network-side device, and sending the UE an association relationship between the scheduled carrier group and the corresponding scheduling carrier. The configuration message and association relationship of the scheduled carrier group are used to instruct the UE to determine the scheduled carrier group and the scheduling carrier. Therefore, one scheduling carrier can correspond to a group of scheduled carriers, thereby enabling a single DCI signaling to schedule multiple PDSCH / PUSCHs on multiple cells, saving signaling overhead.

[0069] It should be noted that the above-mentioned possible implementations can be executed individually or in combination, and this disclosure does not limit them.

[0070] This disclosure provides another carrier scheduling method. Figure 3 This is a flowchart illustrating another carrier scheduling method provided in an embodiment of this disclosure. This carrier scheduling method can be applied to network-side devices. The carrier scheduling method can be executed alone, or it can be executed in conjunction with any embodiment of this disclosure or possible implementations within those embodiments, or it can be executed in conjunction with any technical solution in related technologies.

[0071] like Figure 3 As shown, the carrier scheduling method may include the following steps: Step 301: Send the configuration message of the scheduled carrier group to the UE.

[0072] In the embodiments of this disclosure, step 301 can be implemented in any of the various embodiments of this disclosure. This disclosure does not limit this and will not elaborate further.

[0073] Step 302: Send the association relationship between the scheduled carrier group and the corresponding scheduled carrier to the UE through the third RRC signaling and / or the third MAC CE signaling.

[0074] Among them, the configuration message and association of the scheduled carrier group are used to instruct the UE to determine the scheduled carrier group and the scheduled carrier.

[0075] In one possible implementation of the embodiments of this disclosure, the network-side device can send the association relationship between the scheduled carrier group and the scheduled carrier corresponding to the scheduled carrier group to the UE through RRC signaling, referred to as the third RRC signaling in this disclosure.

[0076] As an example, network-side devices can configure a scheduled carrier to correspond to a group of scheduled carriers via third RRC signaling.

[0077] In another possible implementation of the embodiments of this disclosure, the network-side device can send the association relationship between the scheduled carrier group and the scheduled carrier corresponding to the scheduled carrier group to the UE through MAC CE signaling, which is referred to as the third MAC CE signaling in this disclosure.

[0078] As an example, network-side devices can configure a scheduled carrier to correspond to a group of scheduled carriers via a third MAC CE signaling.

[0079] In another possible implementation of the embodiments of this disclosure, the network-side device can send the association relationship between the scheduled carrier group and the scheduled carrier corresponding to the scheduled carrier group to the UE through the third RRC signaling and the third MAC CE signaling.

[0080] As an example, a network-side device can configure a scheduled carrier to correspond to a scheduled carrier group via third RRC signaling, or it can configure a scheduled carrier to correspond to multiple scheduled carrier groups via third RRC signaling. When a network-side device configures a scheduled carrier to correspond to multiple scheduled carrier groups via third RRC signaling, meaning that one scheduled carrier has an association with multiple scheduled carrier groups, the network-side device can also indicate the unique scheduled carrier group corresponding to each scheduled carrier via third MAC CE signaling, that is, the one-to-one correspondence between the scheduled carrier group and the scheduled carrier is indicated via third MAC CE signaling.

[0081] Therefore, network-side devices can transmit the association between the scheduled carrier group and the corresponding scheduled carrier in various ways, which can improve the flexibility and applicability of the method.

[0082] The carrier scheduling method of this disclosure involves sending a configuration message of a scheduled carrier group to the UE via a network-side device, and sending the UE an association relationship between the scheduled carrier group and the corresponding scheduling carrier. The configuration message and association relationship of the scheduled carrier group are used to instruct the UE to determine the scheduled carrier group and the scheduling carrier. Therefore, one scheduling carrier can correspond to a group of scheduled carriers, thereby enabling a single DCI signaling to schedule multiple PDSCH / PUSCHs on multiple cells, saving signaling overhead.

[0083] It should be noted that the above-mentioned possible implementations can be executed individually or in combination, and this disclosure does not limit them.

[0084] This disclosure provides another carrier scheduling method. Figure 4 This is a flowchart illustrating another carrier scheduling method provided in an embodiment of this disclosure. This carrier scheduling method can be applied to network-side devices. The carrier scheduling method can be executed alone, or it can be executed in conjunction with any embodiment of this disclosure or possible implementations within those embodiments, or it can be executed in conjunction with any technical solution in related technologies.

[0085] like Figure 4 As shown, the carrier scheduling method may include the following steps: Step 401: Send the configuration message of the scheduled carrier group to the UE.

[0086] Step 402: Send the association relationship between the scheduled carrier group and the corresponding scheduled carrier to the UE.

[0087] Among them, the configuration message and association of the scheduled carrier group are used to instruct the UE to determine the scheduled carrier group and the scheduled carrier.

[0088] In the embodiments of this disclosure, steps 401 and 402 can be implemented in any of the various embodiments of this disclosure. This disclosure does not limit these steps and will not elaborate further.

[0089] Step 403: Send a scheduling mode indication message to the UE. The scheduling mode indication message is used to indicate the scheduling mode adopted by the UE. The scheduling mode includes joint scheduling mode and independent scheduling mode.

[0090] In this embodiment of the disclosure, the joint scheduling mode refers to one DCI signaling scheduling two or more PDSCH / PUSCH, that is, one scheduling carrier corresponds to multiple scheduled carriers (the scheduled carrier group includes multiple scheduled carriers).

[0091] In this embodiment of the disclosure, the independent scheduling mode means that one DCI signaling schedules one PDSCH / PUSCH, that is, one scheduling carrier corresponds to one scheduled carrier (the scheduled carrier group includes one scheduled carrier).

[0092] In this embodiment of the disclosure, the network-side device can send scheduling mode indication information to the UE, wherein the scheduling mode indication information is used to indicate the scheduling mode adopted by the UE. Correspondingly, after receiving the scheduling mode indication information, the UE can send a response message to the network-side device. Correspondingly, after receiving the response message, the network-side device can switch the scheduling mode of the scheduled carrier group corresponding to the UE according to the response message.

[0093] In one possible implementation of the embodiments of this disclosure, the network-side device can send a scheduling mode indication message to the UE via RRC signaling, referred to as the fourth RRC signaling in this disclosure.

[0094] In another possible implementation of the embodiments of this disclosure, the network-side device can send a scheduling mode indication message to the UE via MAC CE signaling, referred to as the fourth MAC CE signaling in this disclosure.

[0095] Optionally, as a possible implementation, after receiving the HARQ-ACK (Hybrid Automatic Repeat Request-ACK) message corresponding to the PDSCH carrying the fourth MAC CE signaling, the network-side device can switch the scheduling mode of the scheduled carrier group corresponding to the UE.

[0096] For example, if the UE previously used a standalone scheduling mode, and the fourth MAC CE signaling indicates that the UE is using a joint scheduling mode, after receiving the fourth MAC CE signaling, the UE can send a HARQ-ACK message corresponding to the PDSCH carrying the fourth MAC CE signaling back to the network-side device. Thus, after receiving the HARQ-ACK message corresponding to the PDSCH carrying the fourth MAC CE signaling, the network-side device can switch the scheduling mode of the UE's corresponding scheduled carrier group from standalone scheduling mode to joint scheduling mode.

[0097] In another possible implementation of the embodiments of this disclosure, the network-side device can send a scheduling mode indication message to the UE via DCI signaling, referred to as the second DCI signaling in this disclosure.

[0098] As an example, network-side equipment can add a field to the DCI signaling that schedules PDSCH / PUSCH (in this case, the DCI signaling is the second DCI signaling), whereby the added field is used to indicate the scheduling mode adopted by the UE.

[0099] For example, an indication field can be added to the second DCI signaling, and the indication information is located in the aforementioned indication field. For instance, when the indication field is 1 bit, a 1 can indicate the joint scheduling mode and a 0 can indicate the individual scheduling mode. Of course, a 0 can also indicate the joint scheduling mode and a 1 can indicate the individual scheduling mode. For another example, when the indication field is multiple bits, different bit values ​​can be used to indicate the joint scheduling mode or the individual scheduling mode. For instance, taking a 2-bit indication field as an example, a 01 can indicate the joint scheduling mode and a 10 can indicate the individual scheduling mode, or a 11 can indicate the joint scheduling mode and a 00 can indicate the individual scheduling mode, and so on. This disclosure does not impose any limitations on this.

[0100] Optionally, as a possible implementation, when the scheduling mode changes, after the network-side device receives the HARQ-ACK of the PDSCH scheduled by the second DCI signaling, or after receiving the PUSCH scheduled by the second DCI signaling, the scheduling mode of the scheduled carrier group corresponding to the UE can be switched.

[0101] As another example, network-side devices can use new DCI signaling formats, including defining a new RNTI (Radio Network Temporary Identifier), to generate second DCI signaling.

[0102] Optionally, as a possible implementation, when the scheduling mode changes, after the network-side device receives the feedback ACK (ACK knowledge signal) of the second DCI signaling, the scheduling mode of the scheduled carrier group corresponding to the UE can be switched.

[0103] Therefore, network-side devices can send scheduling mode indication messages in multiple ways, which can improve the flexibility and applicability of the method.

[0104] It should be noted that the execution order of steps 401, 402 and 403 is not limited in this embodiment of the present disclosure. The above is only an example of executing steps 401, 402 and 403 in sequence.

[0105] The carrier scheduling method of this disclosure involves sending a configuration message of a scheduled carrier group to the UE via a network-side device, and sending the UE an association relationship between the scheduled carrier group and the corresponding scheduling carrier. The configuration message and association relationship of the scheduled carrier group are used to instruct the UE to determine the scheduled carrier group and the scheduling carrier. Therefore, one scheduling carrier can correspond to a group of scheduled carriers, thereby enabling a single DCI signaling to schedule multiple PDSCH / PUSCHs on multiple cells, saving signaling overhead.

[0106] It should be noted that the above-mentioned possible implementations can be executed individually or in combination, and this disclosure does not limit them.

[0107] This disclosure provides a method for switching scheduling modes. Figure 5 This is a flowchart illustrating a scheduling mode switching method provided in an embodiment of this disclosure. This scheduling mode switching method can be applied to network-side devices. The scheduling mode switching method can be executed alone, or it can be executed in conjunction with any embodiment of this disclosure or possible implementations within those embodiments, or it can be executed in conjunction with any technical solution in related technologies.

[0108] like Figure 5 As shown, the carrier scheduling method may include the following steps: Step 501: Send a scheduling mode indication message to the UE. The scheduling mode indication message is used to indicate the scheduling mode adopted by the UE. The scheduling mode includes joint scheduling mode and independent scheduling mode.

[0109] In this embodiment of the disclosure, the joint scheduling mode refers to one DCI signaling scheduling two or more PDSCH / PUSCH, that is, one scheduling carrier corresponds to multiple scheduled carriers (the scheduled carrier group includes multiple scheduled carriers).

[0110] In this embodiment of the disclosure, the independent scheduling mode means that one DCI signaling schedules one PDSCH / PUSCH, that is, one scheduling carrier corresponds to one scheduled carrier (the scheduled carrier group includes one scheduled carrier).

[0111] In this embodiment of the disclosure, the network-side device can send scheduling mode indication information to the UE, wherein the scheduling mode indication information is used to indicate the scheduling mode adopted by the UE, and the scheduling mode includes joint scheduling mode and independent scheduling mode.

[0112] In one possible implementation of the embodiments of this disclosure, the network-side device can send a scheduling mode indication message to the UE via RRC signaling.

[0113] In another possible implementation of the embodiments of this disclosure, the network-side device can send a scheduling mode indication message to the UE via MAC CE signaling.

[0114] In another possible implementation of the embodiments of this disclosure, the network-side device can send a scheduling mode indication message to the UE via DCI signaling.

[0115] As an example, network-side devices can add a field to the DCI signaling that schedules PDSCH / PUSCH, where the added field is used to indicate the scheduling mode adopted by the UE.

[0116] For example, an indication field can be added to the DCI signaling, and the indication information is located in the aforementioned indication field. For instance, when the indication field is 1 bit, a 1 can indicate the joint scheduling mode and a 0 can indicate the individual scheduling mode. Of course, a 0 can also indicate the joint scheduling mode and a 1 can indicate the individual scheduling mode. As another example, when the indication field is multiple bits, different bit values ​​can be used to indicate the joint scheduling mode or the individual scheduling mode. For instance, taking a 2-bit indication field as an example, a 01 can indicate the joint scheduling mode and a 10 can indicate the individual scheduling mode, or a 11 can indicate the joint scheduling mode and a 00 can indicate the individual scheduling mode, and so on. This disclosure does not impose any limitations on this.

[0117] As another example, network-side devices can use a new DCI signaling format, including defining a new RNTI, to generate the aforementioned DCI signaling.

[0118] Step 502: Receive the response message from the UE and switch the scheduling mode of the scheduled carrier group corresponding to the UE according to the response message.

[0119] In this embodiment of the disclosure, after receiving the scheduling mode indication information, the UE can send a response message to the network-side device. Correspondingly, after receiving the response message, the network-side device can switch the scheduling mode of the scheduled carrier group corresponding to the UE according to the response message.

[0120] As one possible implementation, after receiving the HARQ-ACK message corresponding to the PDSCH carrying the aforementioned MAC CE signaling, the network-side device can switch the scheduling mode of the scheduled carrier group corresponding to the UE.

[0121] As another possible implementation, after receiving the HARQ-ACK of the PDSCH scheduled by the DCI signaling, or after receiving the PUSCH scheduled by the DCI signaling, the network-side device can switch the scheduling mode of the scheduled carrier group corresponding to the UE.

[0122] As another possible implementation, after receiving the feedback ACK of DCI signaling, the network-side device can switch the scheduling mode of the scheduled carrier group corresponding to the UE.

[0123] The scheduling mode switching method of this disclosure embodiment sends a scheduling mode indication message to the UE through a network-side device. The scheduling mode indication message indicates the scheduling mode adopted by the UE, including a joint scheduling mode and an independent scheduling mode. The method also receives a response message from the UE and switches the scheduling mode of the scheduled carrier group corresponding to the UE based on the response message. Therefore, the network-side device can switch the scheduling mode of the scheduled carrier group corresponding to the UE.

[0124] It should be noted that the above-mentioned possible implementations can be executed individually or in combination, and this disclosure does not limit them.

[0125] This disclosure provides another carrier scheduling method. Figure 6 This is a flowchart illustrating another carrier scheduling method provided in an embodiment of the present disclosure. This carrier scheduling method can be applied to a UE.

[0127] Step 602: Receive the association relationship between the scheduled carrier group and the corresponding scheduled carrier sent by the network-side device.

[0128] Step 603: Determine the scheduled carrier group and the scheduled carrier based on the configuration message and association relationship of the scheduled carrier group.

[0129] In one possible implementation of this disclosure, the UE can determine the scheduled carrier group to which each scheduled carrier belongs based on the configuration message of the scheduled carrier group; and determine the scheduled carrier based on the association between the scheduled carrier group and the corresponding scheduled carrier.

[0130] In one possible implementation of this disclosure, the configuration message of the scheduled carrier group includes the number of one or more scheduled carrier groups, and the number of the scheduled carriers contained in each scheduled carrier group.

[0131] In one possible implementation of this disclosure, when the configuration message of the scheduled carrier group includes one or more scheduled carrier groups, the UE may also receive indication information sent by the network-side device, wherein the indication information is used to indicate to the UE the number of the scheduled carrier corresponding to each scheduled carrier group.

[0132] In one possible implementation of this disclosure, the UE may receive a configuration message of a scheduled carrier group sent by a network-side device via a first RRC signaling.

[0133] In one possible implementation of this disclosure, the UE may receive the association relationship sent by the network-side device through third RRC signaling and / or third MAC CE signaling.

[0134] In one possible implementation of this disclosure, the UE may also receive a scheduling mode indication message sent by a network-side device, wherein the scheduling mode includes a joint scheduling mode and an independent scheduling mode; and determine the scheduling mode adopted by the UE according to the scheduling mode indication message.

[0135] In one possible implementation of this disclosure, the UE may receive a scheduling mode indication message sent by the network-side device via a fourth RRC signaling.

[0136] In one possible implementation of this disclosure, the UE may receive a scheduling mode indication message sent by the network-side device via a fourth MACCE signaling.

[0137] In one possible implementation of this disclosure, the UE may receive a scheduling mode indication message sent by the network-side device via a second DCI signaling.

[0138] It should be noted that the aforementioned Figures 1 to 5 The explanation of the method executed by the network-side device in any embodiment also applies to the method executed by the UE in the same embodiment. The implementation principle is similar and will not be repeated here.

[0139] The carrier scheduling method of this disclosure involves the UE receiving a configuration message of a scheduled carrier group sent by a network-side device, and receiving an association relationship between the scheduled carrier group and the corresponding scheduling carrier sent by the network-side device. Based on the configuration message and the association relationship, the UE determines the scheduled carrier group and the scheduling carrier. Therefore, one scheduling carrier can correspond to a group of scheduled carriers, enabling a single DCI signaling to schedule multiple PDSCH / PUSCHs on multiple cells, thus saving signaling overhead.

[0140] It should be noted that the above-mentioned possible implementations can be executed individually or in combination, and this disclosure does not limit them.
