[0002] In the current wireless communication system, if the base station is configured with cross-carrier scheduling, the terminal only detects and receives the corresponding downlink control channel on the scheduling carrier, and determines the target carrier of the received DCI scheduling through the CIF (Carrier indicator) field contained in the DCI (Downlink Control Information). Data on different scheduling carriers are scheduled through different DCIs.

[0145] In order to increase scheduling efficiency and save DCI overhead, future communication technologies may need to consider using a DCI sent on a scheduling cell to schedule data transmission on multiple scheduled carriers. The combination of multiple carriers scheduled by a DCI needs to be dynamically changed according to business conditions. However, when a DCI is used to schedule data transmission on multiple CCs (component carriers), there is currently no clear solution for how to determine the multiple CCs scheduled by the DCI.

[0146] Based on this, a carrier indication scheme is also provided in an embodiment of the present invention. The specific implementation of the present invention is described below with reference to the accompanying drawings.

[0147] In the description process, the implementation on the UE and base station sides will be described respectively, and then an example of the coordinated implementation of the two will be given to better understand the implementation of the solution given in the embodiment of the present invention. This description does not mean that the two must be implemented in coordination or must be implemented separately. In fact, when the UE and the base station are implemented separately, they also solve the problems on the UE side and the base station side respectively, and when the two are used in combination, better technical effects will be obtained.

[0148] Figure 1 A schematic diagram of a flow chart of a carrier determination method on a terminal side is provided, as shown in the figure, which may include:

[0149] Step 101: A terminal receives a DCI, where the DCI schedules N CCs, where N is a positive integer greater than or equal to 2.

[0150] Step 102: The terminal determines N CCs scheduled by the base station through the DCI.

[0151] Correspondingly, an indication scheme on the base station side is also provided.

[0152] Figure 2 The flowchart of the carrier indication method implementation on the network side is shown in the figure, which may include:

[0153] Step 201: The base station determines N CCs to be scheduled, where N is a positive integer greater than or equal to 2.

[0154] Step 202: The base station indicates the N CCs scheduled on one DCI to the terminal.

[0155] Specifically, the base station indicates a combination of multiple CCs scheduled by a DCI through the information field already included in the current DCI or introduces a new information field or configures through high-level signaling. After receiving the scheduled DCI, the terminal determines the multiple CCs for data transmission by parsing the information field already included in the DCI or the newly introduced information field or high-level signaling.

[0156] The specific instructions are given below.

[0157] In implementation, the terminal determines the N CCs scheduled by the base station through the DCI in one of the following ways or a combination thereof:

[0158] Determine the N CCs scheduled by the DCI according to the CIF field in the DCI; or,

[0159] Determine the N CCs scheduled by the DCI according to a bit field in the DCI used to indicate the N CCs scheduled by the DCI; or,

[0160] The N CCs scheduled by the DCI are determined according to an instruction of a higher layer signaling.

[0161] Accordingly, in implementation, the base station indicates the N CCs scheduled by the terminal base station through DCI in one of the following ways or a combination thereof:

[0162] Indicating the N CCs scheduled by the DCI by using a CIF field in the DCI; or,

[0163] Indicating the N CCs scheduled by the DCI through a bit field in the DCI used to indicate the N CCs scheduled by the DCI; or,

[0164] The N CCs scheduled by the DCI are indicated through high-layer signaling.

[0165] 1. Indicating the implementation of the N CCs scheduled by the DCI through the CIF field in the DCI.

[0166] In implementation, when determining the N CCs scheduled by the DCI based on the CIF field in the DCI, the CIF field contains information for indicating the N CCs including the scheduled carrier; or, the CIF field contains information for indicating a combination of N CCs other than the scheduled carrier, wherein the scheduled carrier is the carrier for sending the DCI.

[0167] Correspondingly, in implementation, when the base station indicates the N CCs scheduled by the DCI through the CIF field in the DCI, the CIF field contains information for indicating the N CCs including the scheduled carrier; or, the CIF field contains information for indicating a combination of N CCs other than the scheduled carrier, wherein the scheduled carrier is the carrier for sending the DCI.

[0168] Specifically, the CIF information field included in the one scheduling DCI is used to indicate data transmission on N carriers including the scheduling carrier; or, the CIF information field included in the one scheduling DCI is used to indicate a combination of N carriers excluding the scheduling carrier.

[0169] 1. Implementation of information indicating N CCs including scheduled carriers.

[0170] In implementation, when the CIF field includes information indicating N CCs including a scheduled carrier, the N CCs scheduled by the base station are determined in one of the following ways or a combination thereof:

[0171] Indicated in the CIF field is a group of carriers in a plurality of carrier combinations, wherein the plurality of carrier combinations are pre-configured through high-layer signaling, and each carrier combination includes a scheduled carrier; or,

[0172] When N=2, the CIF is used to indicate a scheduled carrier other than the scheduling carrier; or,

[0173] The CIF indicates the starting carrier number of the N carriers scheduled by the DCI, and N consecutive CCs starting from the starting carrier number.

[0174] Correspondingly, in implementation, when the base station includes information indicating N CCs including the scheduled carrier in the CIF field, the base station indicates the N CCs scheduled by the base station in one of the following ways or a combination thereof:

[0175] Indicated in the CIF field is a group of carriers in a plurality of carrier combinations, wherein the plurality of carrier combinations are pre-configured through high-layer signaling, and each carrier combination includes a scheduled carrier; or,

[0176] When N=2, the CIF is used to indicate a scheduled carrier other than the scheduling carrier; or,

[0177] The CIF indicates the starting carrier number of the N carriers scheduled by the DCI, and N consecutive CCs starting from the starting carrier number.

[0178] The specific ones are as follows:

[0179] 1) The combination of the N scheduled carriers is pre-configured through high-level signaling (e.g., RRC signaling (RRC signaling; RRC: Radio Resource Control)), and the CIF is used to indicate data transmission on a group of carriers including the scheduled carrier scheduled by the DCI, and the scheduled carrier specifically refers to the carrier on which the scheduled DCI is sent.

[0180] 2) When N=2, the CIF is used to indicate a scheduled carrier other than the scheduling carrier scheduled by the DCI, that is, the DCI indicates data transmission on a total of two carriers, namely, the scheduling carrier and one scheduled carrier. For example, when CC#0 is the scheduling carrier and the scheduled carrier number indicated by the CIF is CC#5, the DCI schedules data transmission on CC#0 and CC#5.

[0181] 3) The CIF indicates the starting carrier number of the multiple carriers scheduled by the one DCI, and the one DCI schedules data transmission on N consecutive CCs starting from the CC indicated by the CIF.

[0182] During implementation, the terminal side may further include:

[0183] When the CIF field points to the scheduled carrier, it means that the DCI does not support simultaneous scheduling of multiple CCs at this time.

[0184] Accordingly, in implementation, the base station side may further include:

[0185] When the CIF field points to the scheduled carrier, it indicates that the DCI does not support simultaneous scheduling of multiple CCs at this time.

[0186] Specifically, when the CIF field points to the CC where the DCI is transmitted, it means that simultaneous scheduling of multiple CCs is not supported at this time.

[0187] In implementation, before the terminal determines the N CCs scheduled by the base station through the DCI, the method further includes:

[0188] When the DCI coincides with a PDCCH candidate of other DCIs on the scheduled carrier and the DCI formats are the same, it is determined that the DCI transmitted on the PDCCH candidate is the DCI for scheduling N CCs.

[0189] Accordingly, in implementation, the base station side may further include:

[0190] The configuration DCI overlaps with the PDCCH candidate of other DCIs on the scheduling carrier, and the DCI format is the same, so as to indicate that the DCI transmitted on the PDCCH candidate is the DCI for scheduling N CCs.

[0191] Specifically, when a scheduling DCI for scheduling multiple CCs completely overlaps with a PDCCHcandidate (candidate PDCCH; PDCCH: physical downlink control channel) of other scheduling DCIs on the scheduling carrier, and the DCI format (DCI format) is the same, the terminal considers that the DCI transmitted on the PDCCH candidate is the DCI for scheduling multiple CCs.

[0236] Specifically, the N CCs scheduled by the one DCI are indicated through high-level signaling. Further, the high-level configuration is per search space configuration or per CORESET (per control resource set; CORESET: control resource set, Control resource set) configuration, that is, indicating that a DCI transmitted in a specific search space or CORESET is used to schedule data transmission on N CCs.

[0237] During implementation, the method may further include:

[0238] The combination of N CCs is updated through MAC CE.

[0239] Specifically, the combination of the N scheduled carriers may be updated through MAC CE.

[0240] The following is an explanation through examples.

[0241] Embodiment 1:

[0242] The network side schedules data transmission on multiple CCs through one DCI. The base station indicates the data transmission on N carriers scheduled by the DCI through the CIF field carried in the DCI. After receiving the DCI, the terminal determines data transmission on N carriers through the CIF field carried in the DCI. In this embodiment, it is assumed that N=2.

[0243] Assume that the CIF field in the DCI contains 3 bits. Then the CIF field is used to indicate that the DCI schedules other carriers scheduled by the DCI in addition to the data transmission on the current carrier. For example, a DCI for scheduling data transmission on multiple CCs is sent in the search space determined by nCI. At this time, nCI = 0, then the CIF field is a non-zero value, which is used to indicate a carrier in the carrier set for cross-carrier scheduling configured by the base station.

[0244] For example, the CIF field contains 3 bits of information, and the CCs for cross-carrier scheduling configured by the base station for the terminal are {CC#0, CC#5, CC#6, CC#13, CC#15, CC#19, CC#23, CC#26}, and CC#0 is the scheduled carrier. The set of scheduled carriers indicated by the CIF field at this time is shown in the following table. That is, the current RRC configuration signaling can be reused at this time, and there is no need to introduce new RRC parameters to configure the scheduled carriers other than the scheduled carrier.

[0245]

[0246] When a scheduling DCI for scheduling multiple CCs completely overlaps with a PDCCH candidate for scheduling other scheduling DCIs on the scheduling carrier and has the same DCI format, the terminal considers that the DCI transmitted on the PDCCH candidate is the DCI for scheduling multiple CCs.

[0247] Further, the base station may update the combination of the N scheduled carriers through MAC CE.

[0248] Embodiment 2:

[0249] The network side schedules data transmission on multiple CCs through one DCI. The base station indicates the data transmission on the N carriers scheduled by the DCI through the CIF field carried in the DCI. After receiving the DCI, the terminal determines the data transmission on the N carriers through the CIF field carried by the DCI. In this embodiment, it is assumed that N=3, that is, the one DCI schedules data transmission on the other two carriers except the scheduled carrier.

[0250] Assume that the CIF field in the DCI contains 3 bits. Then the CIF field is used to indicate that the DCI schedules the other two carriers scheduled by the DCI in addition to the data transmission on the carrier. The combination of the two carriers is configured in advance through high-level signaling (RRC signaling), for example, the following corresponding relationship is configured through high-level signaling. Of course, the following table is only a specific example, and this embodiment does not impose any limitation on the carrier combination.

[0251]

[0252] When a scheduling DCI for scheduling multiple CCs completely overlaps with a PDCCH candidate for scheduling other scheduling DCIs on the scheduling carrier and has the same DCI format, the terminal considers that the DCI transmitted on the PDCCH candidate is the DCI for scheduling multiple CCs.

[0253] Further, the base station may update the combination of the N scheduled carriers through MAC CE.

[0254] Embodiment 3:

[0255] The network side schedules data transmission on multiple CCs through one DCI. The base station indicates the data transmission on the N carriers scheduled by the DCI through the CIF field carried in the DCI. After the terminal receives the DCI, it determines the starting carrier number of the N carriers through the CIF field carried by the DCI. The one DCI schedules data transmission on N consecutive CCs starting from the CC indicated by the CIF. Among them, N can be determined by the following method:

[0256] N is configured through high-level signaling. When the high-level configuration is default, it means that the DCI can only schedule data transmission on a single carrier;

[0257] Alternatively, N is determined by a method predefined by the protocol, for example, N=2;

[0258] Alternatively, N is indicated by a newly introduced information bit in the DCI, for example, an information field of M bits is used to indicate the number of 2M consecutive carriers pre-configured by high-level signaling, or to indicate that the number of consecutive carriers is any value between 1 and 2M.

[0259] Embodiment 4:

[0260] As in Embodiment 2-3, the one scheduling DCI indicates data transmission on N scheduled carriers other than the scheduling carrier through the CIF field. The combination of the N scheduled carriers is pre-configured through high-layer signaling and does not include the scheduling carrier.

[0261] Embodiment 5:

[0262] The network side schedules data transmission on multiple CCs through one DCI. A new carrier combination indication field is introduced in the DCI to indicate the combination of N CCs scheduled by the DCI. The specific method is similar to that of Embodiments 1-4 and will not be described in detail here.

[0263] Embodiment 6:

[0264] The network side schedules data transmission on multiple CCs through one DCI. The base station indicates the combination of multiple CCs scheduled by the DCI through high-layer signaling. The combination of multiple CCs can be:

[0265] CC combination including scheduled carrier;

[0266] Or, a CC combination that does not include a scheduled carrier;

[0267] There is no restriction on the specific combination in the implementation. Specifically, assuming that the multiple CC combinations configured by the high-level signaling are {CC#0, CC#1} or {CC#1}, and assuming that CC#0 is the scheduled carrier, it means that the DCI schedules data transmission on CC#0 and CC#1 at the same time. Of course, there is no restriction on the specific number of CCs in the implementation.

[0268] Furthermore, the high-level configuration is a per search space configuration or a per CORESET configuration, that is, indicating that a DCI transmitted within a specific search space or CORESET is used to schedule data transmission on the multiple CCs.

[0269] Furthermore, the combination of the multiple scheduled carriers may be updated via MAC CE.

[0270] Based on the same inventive concept, an embodiment of the present invention also provides a base station, a user terminal, a carrier determination device, a carrier indication device, and a computer-readable storage medium.
