Description

Technical Field

[0001] This application relates to the field of wireless communication technologies, and in particular, to a scheduling method and device. Background Art

[0002] The Physical Downlink Control Channel (PDCCH) carries Downlink Control Information (DCI), which includes resource allocation and other control information for one or more User Equipments (UEs). The DCI is divided into different formats according to the type of indication information, and each format corresponds to a size or parsing method of the DCI information. Referring to 3GPP TS 38.211 V17.0.0, the NR system currently supports three DCI formats for scheduling the Physical Downlink Shared Channel (PDSCH): DCI format 1_0, DCI format 1_1, and DCI format 1_2, and three DCI formats for scheduling the Physical Uplink Shared Channel (PUSCH): DCI format 0_0, DCI format 0_1, and DCI format 0_2. These 6 types of DCI are used to schedule the PDSCH or PUSCH of a cell.

[0003] Each PDCCH contains a Cyclic Redundancy Check (CRC) for the UE to verify whether the received PDCCH is correct, and the CRC is scrambled using a Radio Network Temporary Identifier (RNTI) related to the UE, enabling the UE to detect and determine which PDCCHs it needs to receive.

[0004] The CRC of the PDCCH using a certain DCI format can be scrambled with different RNTIs, representing different data transmission authorization methods scheduled by the current PDCCH. Different data transmission authorization methods correspond to different interpretation methods of at least one control field in the DCI format. The RNTI is a 16-bit identifier, including: TC-RNTI, C-RNTI, CS-RNTI, MCS-RNTI, SP-CSI-RNTI, SI-RNTI, P-RNTI, RA-RNTI, etc. Each RNTI corresponds to a different use of the DCI information in the PDCCH. For example, the TC-RNTI is assigned to the UE for Message 2 in the random access phase and is used to identify the UE before successful random access; the C-RNTI is used after successful random access and is used for the PDCCH of dynamically scheduling the uplink and downlink shared channels of the UE; the SI-RNTI is used for the PDCCH of the UE to schedule system information.

[0005] In the PDCCH for scheduling the PDSCH, when the CRC is scrambled with the C-RNTI, it is used to schedule dynamic PDSCH data, and when the CRC is scrambled with the CS-RNTI, it is used to activate or deactivate semi-persistent scheduled PDSCH data. When the CRC is scrambled with the MCS-RNTI and the C-RNTI, it is used to schedule the dynamic PDSCH. In these two cases, the MCS field in the PDCCH for determining the modulation and coding scheme corresponds to different MCS tables, and each case corresponds to a predefined MCS table, that is, the MCS field in the PDCCH is interpreted through the predefined MCS table.

[0006] According to the prior art, the PDCCH using DCI format 0_X or DCI format 1_X has only one CRC check, and there is only one RNTI for scrambling the CRC check bit. In this way, the transmission authorization methods of multiple PUSCHs scheduled by DCI format 0_X are the same, and the transmission authorization methods of multiple PDSCHs scheduled by DCI format 1_X are the same. In this way, the scheduling flexibility of DCI format 0_X and DCI format 1_X is greatly limited, and the data transmission efficiency in the system is also low. Summary of the Invention

[0051] To make the objectives, technical solutions and advantages of the present application clearer, the technical solutions of the present application will be clearly and completely described below in conjunction with specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts shall fall within the protection scope of the present application.

[0052] The following will detail the technical solutions provided by each embodiment of the present application in conjunction with the drawings.

[0053] Figure 1 It is a schematic diagram of the pre - transmission processing procedure of the prior - art PDCCH.

[0054] The pre - transmission processing of the PDCCH includes: determining DCI information, adding CRC, scrambling the CRC with RNTI. Then perform interleaving and channel coding, and map to transmission resources after modulation.

[0055] When the UE supports carrier aggregation, one scheduling indication method is to separately send PDCCHs carrying DCI format 1_0, 1_1, 1_2, 0_0, 0_1, or 0_2 for the scheduled carriers. Another scheduling indication method is to design a new DCI format 0_X for scheduling multiple PUSCHs on multiple cells, and design a new DCI format 1_X for scheduling multiple PDSCHs on multiple cells. Among them, the transport blocks carried by the respective PUSCHs scheduled by the DCI format 0_X are independent of each other, and the transport blocks carried by the respective PDSCHs scheduled by the DCI format 1_X are independent of each other.

[0056] The application scenario of this application is for a network device (gNB) to schedule data of a terminal device (UE). The core concept is to include indication information in the DCI format 0_X / DCI format 1_X to determine the respective transmission authorization methods of the multiple PUSCHs / PDSCHs scheduled.

[0057] Figure 2 It is a flowchart of an embodiment of the method of this application.

[0058] This application proposes a scheduling method in a wireless communication system, including the following steps:

[0059] Step 101, the CRC in the PDCCH is scrambled with a set identifier; the set identifier is the first RNTI, or an identifier generated by scrambling the first RNTI.

[0060] Step 102, the PDCCH is used to schedule N physical shared channels, N≥2; the PDCCH carries indication information, and the indication information is used to identify the respective transmission authorization methods of the N physical shared channels.

[0061] Preferably, the first RNTI is used as the indication information. The CRC of the PDCCH uses the first RNTI. On the one hand, it is used for the terminal device to identify whether the PDCCH is control information targeted at itself. On the other hand, it is used to determine the transmission authorization mode of each of the N physical shared channels scheduled by the PDCCH. The network device and the terminal device preset the correspondence between the first RNTI and the transmission authorization mode of each of the N physical shared channels. For example, assume N = 2. When the preset value of the first RNTI is X1, the transmission authorization modes of the first physical shared channel and the second physical shared channel are both configured uplink authorizations; when the value of the first RNTI is X2, the transmission authorization mode of the first physical shared channel is a configured uplink authorization, and the transmission authorization mode of the second physical shared channel is a dynamic uplink authorization; when the value of the first RNTI is X3, the transmission authorization mode of the first physical shared channel is a dynamic uplink authorization, and the transmission authorization mode of the second physical shared channel is a configured uplink authorization; when the value of the first RNTI is X4, the transmission authorization modes of the first physical shared channel and the second physical shared channel are both dynamic uplink authorizations... If the indication information is equivalent to the first RNTI, there is no need to preset a dedicated field in the PDCCH to indicate the transmission authorization mode of each of the N physical shared channels. The indication efficiency of the control information is high, and it overcomes the constraints on the scheduling flexibility of DCI format 0_X / DCI format 1_X, improving the data transmission efficiency in the system.

[0062] Alternatively, preferably, the sequence scrambled with the first RNTI is used as the indication information. The network device and the terminal device preset the correspondence between the scrambling sequence and the transmission authorization mode of each of the N physical shared channels. The network device or the terminal device determines the transmission authorization mode of each of the N physical shared channels according to the correspondence between the scrambling sequence and the transmission authorization mode of each of the N physical shared channels, and the first RNTI.

[0063] Preferably, the indication information is carried by a set field in the PDCCH, and the set field is independent of the scheduling fields of each of the N physical shared channels. For example: The target field of the DCI format of the PDCCH carries the indication information. The target field is independent of the scheduling indication fields of the at least two physical shared channels.

[0064] For example, the network device and the terminal device preset the correspondence between the indication information (i.e., the indication value of the target field in this embodiment) and the transmission authorization modes of N physical shared channels. The correspondence can be indexed by the first configuration information. For example, N = 2, and taking the target field containing 2 bits as an example. When the preset target field indicates "00", the transmission authorization modes of the first physical shared channel and the second physical shared channel are both configured uplink authorizations; when the target field indicates "01", the transmission authorization mode of the first physical shared channel is a configured uplink authorization, and the transmission authorization mode of the second physical shared channel is a dynamic uplink authorization; when the target field indicates "10", the transmission authorization mode of the first physical shared channel is a dynamic uplink authorization, and the transmission authorization mode of the second physical shared channel is a configured uplink authorization; when the target field indicates "11", the transmission authorization modes of the first physical shared channel and the second physical shared channel are both dynamic uplink authorizations.

[0065] At this time, the terminal device determines the transmission authorization modes of the N physical shared channels respectively by obtaining the information carried in the target field in the PDCCH. If the target field is independent of the scheduling indication fields of the at least two physical shared channels, the transmission authorization modes of the N physical shared channels can be jointly indicated, saving the control information load. For example, N = 8, and the set of transmission authorization modes contains 6 elements. If the transmission authorization mode of each physical shared channel is independently indicated, then bit information is required. With the joint indication method, the possible combination modes of the transmission authorization modes of the N physical shared channels can be preset, and the valid combination modes of the transmission authorization modes of each physical shared channel can be indicated with fewer bits.

[0066] Alternatively, the indication information is carried by the scheduling indication fields of the N physical shared channels in the PDCCH (see the Figure 3 illustrated embodiment). Optionally, the indication information is carried by the scheduling fields of the at least two physical shared channels respectively. For example, some fields in the first field set indicate which one in the set of transmission authorization modes is the transmission authorization mode of the first PUSCH. The fields in the second field set indicate which one in the set of transmission authorization modes is the transmission authorization mode of the second PUSCH. If the indication information is carried by the scheduling fields of the at least two physical shared channels respectively, the scheduling mode of the transmission authorization mode of each physical shared channel is the most flexible, and the system data transmission efficiency is high. Figure 3Arrangement for multiple physical shared channel scheduling information fields. The PDCCH is used to schedule N physical shared channels, where N ≥ 2. For example, the PDCCH uses DCI format 0_X or DCI format 1_X, which includes the scheduling information of N physical shared channels. Taking DCI format 0_X as an example, assume N = 2. The PDCCH contains a first field set for indicating the scheduling information of the first scheduled PUSCH and a second field set for indicating the scheduling information of the second scheduled PUSCH. The first field set and the second field set are independent of each other. Optionally, in addition to the first field set and the second field set, the PDCCH also includes a common field set, which is the common scheduling information for controlling the first PUSCH and the second PUSCH.

[0067] Preferably, in the PDCCH, the scheduling indication field of the nth physical shared channel contains a second RNTI corresponding to the transmission authorization mode of the nth physical shared channel, where n ≤ N (see Figure 4 the illustrated embodiment). Optionally, if the target field is independent of the scheduling indication fields of the N physical shared channels, the target field may contain a second RNTI related to the scheduling information of each of the N physical shared channels. The processing procedure for the network device to send the DCI information in the PDCCH includes adding CRCs to the scheduling information of each of the N physical shared channels respectively, scrambling each CRC with the second RNTI corresponding to its transmission authorization mode, and then adding a unified CRC to these information and scrambling the CRC position with the first RNTI.

[0068] Figure 4 Schematic diagram of the multi-level RNTI scrambling processing procedure. As shown in the figure, after adding CRC-1 to the scheduling information of the first physical shared channel, scramble this CRC-1 with the second RNTI-1 corresponding to its transmission authorization mode. After adding CRC-2 to the scheduling information of the second physical shared channel respectively, scramble this CRC-2 with the second RNTI-2 corresponding to its transmission authorization mode,..., after adding CRC-N to the scheduling information of the Nth physical shared channel respectively, scramble this CRC-N with the second RNTI-N corresponding to its transmission authorization mode. The information after adding CRC and scrambling for the scheduling information of each physical shared channel is taken as a whole and a comprehensive CRC is added again. If there is a common field, the information of the common field is added to the DCI before adding the comprehensive CRC, and the comprehensive CRC is added together. Then scramble the first RNTI on the comprehensive CRC.

[0069] It should be noted that the second RNTI exists independently relative to the first RNTI, and the second RNTIs used for scrambling the CRCs of the N physical shared channels are independent of each other and can be the same or different.

[0070] The first RNTI is used for the terminal device to identify whether the control information of the PDCCH is targeted at itself. The second RNTI of the respective scheduling information of N physical shared channels in the PDCCH is used to indicate the respective transmission authorization methods of the data of multiple PUSCH / PDSCH scheduled by DCI format 0_X / DCI format 1_X. In this way, not only is the constraint on the scheduling flexibility of DCI format 0_X / DCI format 1_X overcome, the data transmission efficiency in the system is improved, but also the reception reliability of the PDCCH and the reliability of the indication of the respective transmission authorization methods of N physical shared channels are improved.

[0071] If the physical shared channel is a PUSCH, the transmission authorization methods include at least two of: configured uplink authorization, type-1 dynamic uplink authorization, type-2 dynamic uplink authorization, type-3 dynamic uplink authorization, and semi-persistent CSI scheduling authorization.

[0072] If the physical shared channel is a PDSCH, the transmission authorization methods include at least two of: SPS PDSCH authorization, type-1 dynamic downlink authorization, type-2 dynamic downlink authorization, type-3 dynamic downlink authorization, semi-persistent CSI scheduling authorization, paging downlink authorization, system information downlink authorization, random access response downlink authorization, and message B downlink authorization.

[0073] Step 103: In response to the PDCCH, determine that the kth PUSCH is a configured uplink authorization for new data transmission, or determine that the kth PDSCH is for activating or deactivating SPS PDSCH transmission.

[0074] For the uplink, specifically, if the indication information indicates that the transmission authorization method of the kth PUSCH is a configured uplink authorization and k ≤ N, then:

[0075] The new data indication field corresponding to the kth PUSCH is a first value, and in response to the PDCCH, determine that the kth PUSCH is a configured uplink authorization; or the new data indication field corresponding to the kth PUSCH is a second value, and in response to the PDCCH, determine that the kth PUSCH is a dynamic uplink authorization.

[0076] Preferably, if the indication information indicates that the transmission authorization method of the kth PUSCH is a dynamic uplink authorization, in response to the PDCCH, determine that the kth PUSCH is for new data block transmission and k ≤ N.

[0077] For the downlink, specifically, if the indication information indicates that the transmission authorization method of the kth PDSCH is SPS PDSCH and k ≤ N, then:

[0078] The first characteristic field corresponding to the k-th PDSCH is the third value, and in response to the PDCCH, it is determined that the k-th PDSCH is an active SPS PDSCH transmission; or, the second characteristic field corresponding to the k-th PDSCH is the fourth value, and in response to the PDCCH, it is determined that the k-th PDSCH is a deactivated SPS PDSCH transmission.

[0079] Figure 5 FIG. is a flowchart of an embodiment in which the method of the present application is applied to a network device.

[0080] The present application provides a scheduling method in a wireless communication system for a network device, including the following steps 201 to 203:

[0081] Step 201: Transmit a PDCCH, where the CRC is scrambled with a set identifier. Preferably, the set identifier is a first RNTI, or an identifier generated by scrambling the first RNTI.

[0082] For example, after the network device adds a CRC to the DCI information, it scrambles the CRC position with the first RNTI, and after completing the pre-transmission processing, it transmits the PDCCH.

[0083] For another example, the network device scrambles the first RNTI with the indication information to generate the set identifier.

[0084] Step 202: The PDCCH is used to schedule N physical shared channels, N≥2; the PDCCH carries indication information for identifying the transmission authorization method of each of the N physical shared channels.

[0085] The network device pre-obtains configuration information for determining the correspondence between the indication information and the transmission authorization method of each of the N physical shared channels. After determining the correspondence between the indication information and the combination of the transmission authorization methods of each of the N physical shared channels, the network device determines the indication information according to the correspondence between the indication information and the combination of the transmission authorization methods of each of the N physical shared channels and the transmission authorization method of each of the N physical shared channels to be scheduled.

[0086] Preferably, the indication information is the same as the first RNTI, and the first RNTI corresponds to the transmission authorization mode of each of the N physical shared channels. Optionally, the network device pre-obtains first configuration information for determining the correspondence between the first RNTI and the transmission authorization mode of each of the N physical shared channels. After determining the correspondence between the first RNTI and the transmission authorization mode of each of the N physical shared channels, the network device determines the first RNTI according to the correspondence between the first RNTI and the transmission authorization mode of each of the N physical shared channels, and the transmission authorization mode of each of the scheduled N physical shared channels.

[0087] Alternatively, the indication information is a sequence scrambled with the first RNTI, and a combination of the transmission authorization modes of each of the N physical shared channels corresponds to a preset scrambling sequence. The network device pre-obtains second configuration information for determining the correspondence between the scrambling sequence and the transmission authorization mode of each of the N physical shared channels. After determining the correspondence between the scrambling sequence and the transmission authorization mode of each of the N physical shared channels, the network device determines the scrambling sequence according to the correspondence between the scrambling sequence and the transmission authorization mode of each of the N physical shared channels, and the transmission authorization mode of each of the scheduled N physical shared channels, and then scrambles the first RNTI with the scrambling sequence.

[0088] Step 203: Determine the response of the PDCCH according to the transmission authorization mode of each of the N physical shared channels, and transmit the physical shared channel.

[0089] For the specific response, see step 303. The network device processes according to the transmission authorization mode of each of the N physical shared channels, receives the PDSCH or transmits the PUSCH, or activates / deactivates the SPS PDSCH / configured grant PUSCH.

[0090] Figure 6 This is a flowchart of an embodiment of the method of the present application for a terminal device.

[0091] The present application proposes a scheduling method in a wireless communication system for a terminal device, including the following steps:

[0092] Step 301: Receive a PDCCH, where the CRC is scrambled with a set identifier; the set identifier is the first RNTI, or an identifier generated by scrambling the first RNTI.

[0093] The terminal device obtains the PDCCH through PDCCH blind detection. The first RNTI is used by the terminal device to determine that it needs to respond to this PDCCH. Responding to the PDCCH includes sending or receiving information according to the indication, activating or deactivating the SPS PDSCH / configured grant PUSCH, etc.

[0094] Step 302: The PDCCH is used to schedule N physical shared channels, where N ≥ 2; identify the indication information carried by the PDCCH, and the indication information is used to identify the transmission authorization mode of each of the N physical shared channels.

[0095] After obtaining the PDCCH, the terminal device needs to interpret the indication of the PDCCH. The PDCCH contains indication information for determining the transmission authorization mode of each of the N physical shared channels. The transmission authorization mode of the physical shared channel determines how to interpret the corresponding control field in the PDCCH. Still assuming N = 2, the first physical shared channel is PUSCH, and the corresponding transmission authorization mode is configured grant PUSCH. The first set of fields in the PDCCH corresponding to this PUSCH is the control information of the network device for this configured grant PUSCH. Further, the second physical shared channel is also PUSCH, and the corresponding transmission authorization mode is dynamically scheduled PUSCH. The second set of fields in the PDCCH corresponding to this PUSCH is the control information for this dynamically scheduled PUSCH. The transmission authorization mode of the k-th (k ≤ N) physical shared channel is one of the set of transmission authorization modes, and the interpretation methods of at least one of the control fields corresponding to any two items in the set of transmission authorization modes are different. For example, the control information of the configured grant PUSCH and the control information of the dynamically scheduled PUSCH both include the HARQ process number field. In the control information of the configured grant PUSCH, the HARQ process number field is all indicated as "0" for the terminal device to verify this transmission mode, while the HARQ process number field in the control information of the dynamically scheduled PUSCH is used to indicate the process number of the second PUSCH. The interpretation methods of at least one of the control fields corresponding to any two items are different. Through the indication information, the terminal device determines how to interpret the control information of each physical shared channel in the PDCCH. The field interpretation method corresponding to each physical shared channel corresponds to its transmission authorization mode.

[0096] The terminal device pre-obtains configuration information for determining the correspondence between the indication information and the transmission authorization mode of each of the N physical shared channels. After determining the correspondence between the indication information and the combination of the transmission authorization modes of each of the N physical shared channels, the network device determines the transmission authorization mode of each of the N physical shared channels according to the correspondence between the indication information and the combination of the transmission authorization modes of each of the N physical shared channels, and the identified indication information.

[0097] Preferably, the indication is the same as the first RNTI, and the first RNTI corresponds to the transmission authorization mode of each of the N physical shared channels. Optionally, the terminal device pre-obtains first configuration information for determining the correspondence between the first RNTI and the transmission authorization mode of each of the N physical shared channels. After determining the correspondence between the first RNTI and the transmission authorization mode of each of the N physical shared channels, the terminal device determines the transmission authorization mode of each of the N physical shared channels according to the correspondence between the first RNTI and the transmission authorization mode of each of the N physical shared channels, and the identified first RNTI.

[0098] Alternatively, the indication is a sequence scrambled with the first RNTI, and the first RNTI corresponds to the transmission authorization mode of each of the N physical shared channels. The terminal device pre-obtains second configuration information for determining the correspondence between the scrambling sequence and the transmission authorization mode of each of the N physical shared channels. After determining the correspondence between the scrambling sequence and the transmission authorization mode of each of the N physical shared channels, the terminal device determines the transmission authorization mode of each of the N physical shared channels according to the correspondence between the scrambling sequence and the transmission authorization mode of each of the N physical shared channels, and the identified scrambling sequence.

[0099] Step 303: Determine the transmission authorization mode of each of the N physical shared channels according to the indication information; in response to the PDCCH, transmit the physical shared channel.

[0100] The physical shared channel is a PUSCH, and the set of the transmission authorization modes includes at least two of the configured uplink authorization, the first type of dynamic uplink authorization, the second type of dynamic uplink authorization, the third type of dynamic uplink authorization, and the semi-persistent CSI scheduling authorization; the first type of dynamic uplink authorization, the second type of dynamic uplink authorization, and the third type of dynamic uplink authorization correspond to the TC-RNTI, the C-RNTI, and the MCS-RNTI, respectively.

[0101] Referring to Section 7.3 of 3GPP TS 38.212 V17.0.0, when the PDCCH for scheduling the PUSCH uses DCI format 0_0, DCI format 0_1, or DCI format 0_2, the CRC can be scrambled with any one of CS-RNTI, TC-RNTI, C-RNTI, MCS-RNTI, and SP-CSI-RNTI, corresponding to different interpretation methods for their respective segments in the DCI format. In the embodiments of the present application, in order to overcome the constraints on the scheduling flexibility of DCI format 0_X and improve the data transmission efficiency in the system, the transmission authorization methods for each of the N PUSCHs scheduled by DCI format 0_X are independent and can be the same or different, each being one of the set of transmission authorization methods. The set of transmission authorization methods includes at least two of configured uplink authorization, type-I dynamic uplink authorization, type-II dynamic uplink authorization, type-III dynamic uplink authorization, and semi-persistent CSI scheduling authorization, corresponding to the interpretation of the PUSCH control information field when scrambling the CRC of the PDCCH with CS-RNTI, TC-RNTI, C-RNTI, MCS-RNTI, and SP-CSI-RNTI respectively.

[0102] For the physical shared channel PDSCH, the set of transmission authorization methods includes at least two of SPS PDSCH authorization, type-I dynamic downlink authorization, type-II dynamic downlink authorization, type-III dynamic downlink authorization, semi-persistent CSI scheduling authorization, paging downlink authorization, system information downlink authorization, random access response downlink authorization, and message B downlink authorization; the SPS PDSCH authorization, type-I dynamic downlink authorization, type-II dynamic downlink authorization, type-III dynamic downlink authorization, semi-persistent CSI scheduling authorization, paging downlink authorization, system information downlink authorization, random access response downlink authorization, and message B downlink authorization correspond to CS-RNTI, TC-RNTI, C-RNTI, MCS-RNTI, P-RNTI, SI-RNTI, RA-RNTI, and MSGB-RNTI respectively.

[0103] Referring to Section 7.3 of 3GPP TS 38.212 V17.0.0, when the PDCCH for scheduling the PDSCH uses DCI format 1_0, DCI format 1_1, or DCI format 1_2, the CRC can be scrambled with any one of CS-RNTI, TC-RNTI, C-RNTI, MCS-RNTI, P-RNTI, SI-RNTI, RA-RNTI, and MSGB-RNTI, corresponding to different interpretation methods for their respective segments in the DCI format. In this embodiment, in order to overcome the constraints on the scheduling flexibility of DCI format 1_X and improve the data transmission efficiency in the system, the transmission authorization methods for each of the N PDSCHs scheduled by DCI format 1_X can be different, each being one in the set of transmission authorization methods. The set of transmission authorization methods includes at least two of SPS PDSCH authorization, the first type of dynamic downlink authorization, the second type of dynamic downlink authorization, the third type of dynamic downlink authorization, semi-persistent CSI scheduling authorization, paging downlink authorization, system information downlink authorization, random access response downlink authorization, and message B downlink authorization, corresponding to the interpretation of the PDSCH control information field when scrambling the CRC of the PDCCH with CS-RNTI, TC-RNTI, C-RNTI, MCS-RNTI, P-RNTI, SI-RNTI, RA-RNTI, and MSGB-RNTI respectively.

[0104] The physical shared channel is the PUSCH; when the indication information indicates that the transmission authorization method for the k-th PUSCH is the configured uplink authorization, if the new data indication field corresponding to the k-th PUSCH is the first value, the response to the PDCCH includes determining the k-th PUSCH as the configured uplink authorization; if the new data indication field corresponding to the k-th PUSCH is the second value, the response to the PDCCH includes determining the k-th PUSCH as the dynamic uplink authorization.

[0105] The system MAC entity includes HARQ entities for each serving cell with a configured uplink, which maintain multiple parallel HARQ processes. Each HARQ process supports one TB (Transport Block). Each HARQ process is associated with a HARQ process number. Uplink grants are received dynamically on the PDCCH or configured semi-persistently by the RRC. The MAC entity transmits PUSCH data on the UL-SCH according to the uplink grant. To perform the requested transmission, the MAC layer receives HARQ information from the physical layer. The PUSCH does not have dedicated ACK / NACK feedback, and the UE determines whether the PUSCH is correctly received by whether it obtains a retransmission request from the gNB.

[0106] Referring to 3GPP TS 38.321 V17.0.0, for DCI formats 0_0, 0_1, and 0_2, when the CRC in the PDCCH is scrambled with CS-RNTI, if the field new data indication NDI (New Data indication) is equal to 0, the uplink grant is considered an activated configured uplink authorization. If the field NDI = 1, the uplink grant sent with CS-RNTI is considered a dynamic uplink authorization for scheduling the retransmission of data for the corresponding HARQ process. When the CRC in the PDCCH is scrambled with C-RNTI, if the corresponding HARQ process number is indicated as a configured uplink authorization by a previous uplink grant, regardless of whether the value of the field NDI is 0 or 1, it represents that the current dynamic uplink authorization is a new data block transmission. When DCI format 0_X is used to schedule N PUSCHs, if the PDCCH does not have the indication information and the CRC of the PDCCH is scrambled with C-RNTI or scrambled with CS-RNTI. In this way, it is impossible to distinguish whether the scheduled PUSCHs are retransmissions of data for the HARQ process or new data blocks according to whether the RNTI is CS-RNTI or C-RNTI combined with the status of NDI, so that all the PUSCHs scheduled by DCI format 0_X are either new data block transmissions of dynamic uplink authorizations or retransmissions of the corresponding data of configured uplink authorizations, and the scheduling flexibility of DCI format 0_X is greatly limited.

[0107] In this embodiment, the indication information of the PDCCH is used to determine the transmission authorization method of each of the N physical shared channels, so that each PUSCH scheduled by DCI format 0_X can be a dynamic uplink authorization or a configured uplink authorization. In this way, when the indication information indicates that the transmission authorization method of the kth PUSCH is a configured uplink authorization, if the new data indication field corresponding to the kth PUSCH is the first value, the response to the PDCCH includes determining the kth PUSCH as a configured uplink authorization; if the new data indication field corresponding to the kth PUSCH is the second value, the response to the PDCCH includes determining the kth PUSCH as a dynamic uplink authorization. The first value is, for example, 0, and the second value is, for example, 1.

[0108] The first RNTI is used for the terminal device to identify whether the PDCCH is control information for itself, and the indication information is used to determine the transmission authorization method of each of the multiple PUSCHs scheduled by DCI format 0_X. For the case where the scheduled PUSCH is a configured uplink authorization, it is possible to further combine the NDI indication to determine whether the current PUSCH is an activated configured uplink authorization or a new data transmission of a dynamic uplink authorization, further improving the scheduling flexibility of DCI format 0_X and the data transmission efficiency in the system.

[0109] When the indication information indicates that the transmission authorization mode of the k-th PUSCH is dynamic uplink authorization, the response to the PDCCH includes determining that the k-th PUSCH is used for new data block transmission.

[0110] The physical shared channel is PDSCH; when the indication information indicates that the transmission authorization mode of the k-th PDSCH is SPS PDSCH, if the first characteristic field corresponding to the k-th PDSCH is the third value, the response to the PDCCH includes determining the k-th PDSCH as an active SPS PDSCH transmission; if the second characteristic field corresponding to the k-th PDSCH is the fourth value, the response to the PDCCH includes determining the k-th PDSCH as a deactivated SPS PDSCH transmission.

[0111] Referring to 3GPP TS 38.213 V17.0.0, for DCI formats 1_0, 1_1, and 1_2, when the CRC in the PDCCH is scrambled with CS-RNTI, if the DCI format indication field information therein is '1', the NDI field information is all '0', the DFI flag field (if any) is all '0', and the PDSCH-to-HARQ_feedback field (if any) has a reasonable value, then this PDCCH is the PDCCH for activating SPS PDSCH. If the UE detects that the CRC in the PDCCH is scrambled with C-RNTI and the DCI format indication field information therein is '0', then this PDCCH is the PDCCH for scheduling dynamic PUSCH, etc. If the PDCCH does not have the indication information, when DCI format 1_X is used to schedule N PDSCHs, the CRC of the PDCCH is scrambled with C-RNTI or CS-RNTI. In this way, it is impossible to distinguish the PDCCH for activating SPS PDSCH transmission, the PDSCH for deactivating SPS PDSCH transmission, and the PUDSCH for dynamic scheduling according to whether the RNTI is CS-RNTI or C-RNTI and the status of other fields. As a result, the PUSCH scheduled by DCI format 1_X is the PDCCH for activating SPS PDSCH transmission, the PDSCH for deactivating SPS PDSCH transmission, or the PUDSCH for dynamic scheduling, and the scheduling flexibility of DCI format 1_X is greatly restricted.

[0112] In this embodiment, the indication information of the PDCCH is used to determine the transmission authorization mode of each of the N physical shared channels, so that each PDSCH scheduled by the DCI format 1_X can be any one of an active SPS PDSCH transmission, a deactivated SPS PDSCH transmission, or a dynamic PDSCH transmission. In this way, when the indication information indicates that the transmission authorization mode of the k-th PUSCH is an SPS PDSCH, if the first characteristic field corresponding to the k-th PDSCH is the third value, the response to the PDCCH includes determining the k-th PDSCH as an active SPS PDSCH transmission; if the second characteristic field corresponding to the k-th PDSCH is the fourth value, the response to the PDCCH includes determining the k-th PDSCH as a deactivated SPS PDSCH transmission. When the preset value of the first characteristic field is the third value, the k-th PDSCH is an SPS PDSCH transmission. The first characteristic field is, for example, the DCI format indication field information, the NDI field, the DFI flag field, and the PDSCH-to-HARQ_feedback field. The third value is, for example, the DCI format indication field information is '1', the NDI field information is all '0', the DFI flag field (if any) is all '0', and the PDSCH-to-HARQ_feedback field (if any) has a reasonable value.

[0113] The first RNTI is used for the terminal device to identify whether the PDCCH is control information for itself, and the indication information is used to determine the transmission authorization mode of each of the multiple PDSCHs scheduled by the DCI format 1_X. For the case where the scheduled PDSCH is an SPS PDSCH, the first characteristic field and the second characteristic field can be further combined to determine whether the current response to the PDSCH is an active or deactivated scheduling, further improving the scheduling flexibility of the DCI format 1_X and the data transmission efficiency in the system.
