Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution provided by the embodiment of the present disclosure is also applicable to similar technical problems.

[0172] The data reception processing method and device provided by the present disclosure are described in detail below with reference to the accompanying drawings.

[0173] The moments involved in the various embodiments of the present disclosure are numbered in chronological order, such as moment t1, moment t2, and moment t3, where t2 is the moment after moment t1, t3 is the moment after moment t2, and so on. The present disclosure does not limit this.

[0174] See Figure 2 , Figure 2 This is a flow chart of a data reception processing method provided by an embodiment of the present disclosure, which is configured to be executed by a terminal device. Figure 2 As shown, the method may include but is not limited to the following steps:

[0175] Step 21: Receive first downlink control information DCI sent by a network device, where the first DCI is used to indicate that there is data transmission in a hybrid automatic repeat request HARQ process.

[0176] It can be understood that when the network device determines that there is data transmission in the HARQ process, it can send a first DCI to the terminal device. The first DCI can be the DCI of the PDCCH indicated by the G-RNTI, or it can be the DCI of the PDCCH indicated by the C-RNTI. This disclosure does not limit this.

[0177] After receiving the first DCI, the terminal device can determine that there is data transmission in the HARQ process indicated by the first DCI.

[0178] Step 22: In response to the physical downlink control channel PDCCH identifier corresponding to the first DCI being a broadcast or multicast scheduling identifier, determine the type of data transmitted in the HARQ process indicated by the first DCI according to the type of the first DCI and the content contained in the first DCI.

[0179] The PDCCH identifier may be a unicast scheduling identifier C-RNTI, or a broadcast or multicast scheduling identifier G-RNTI, which is not limited in the present disclosure.

[0180] Correspondingly, the type of the first DCI may be a DCI with a unicast scheduling identifier, or may be a DCI with a broadcast or multicast scheduling identifier, which is not limited in the present disclosure.

[0181] Optionally, the unicast scheduling identifier style or presentation form may be pre-set according to protocol agreement or network device configuration, such as C-RNTI-1, C-RNTI-2, etc., which is not limited in this disclosure.

[0182] Optionally, the style or presentation form of the broadcast or multicast scheduling identifier can be set in advance according to the protocol agreement or network equipment configuration, for example, it can be: G-RNTI-1, G-RNTI-2, etc., which is not limited in this disclosure.

[0183] Optionally, the type of the first DCI may be determined according to a radio network temporary identifier (RNTI) corresponding to the first DCI.

[0184] For example, the PDCCH corresponding to the first DCI is indicated by C-RNTI, that is, the RNTI corresponding to the first DCI is C-RNTI, then the type of the first DCI can be a DCI with a unicast scheduling identifier, that is, the PDCCH type indicated by C-RNTI; or, the PDCCH corresponding to the first DCI is indicated by G-RNTI, that is, the RNTI corresponding to the first DCI is G-RNTI, then the type of the first DCI can be a DCI with a broadcast or multicast scheduling identifier, that is, the PDCCH type indicated by G-RNTI, etc., and the present disclosure does not limit this.

[0185] Optionally, the content included in the first DCI may include at least one of the following: a value of a new data indicator (New Data Indicator, NDI) or a HARQ process number.

[0186] Optionally, the possible values of NDI may be pre-set according to the protocol agreement or network device configuration. For example, the value of NDI may be 1, or the value of NDI may be 0, etc., which is not limited in this disclosure.

[0187] Optionally, the style or presentation form of the HARQ process number may be pre-set, for example, it may be: HARQ process 1 (HARQ process 1), HARQ process 2, etc., which is not limited in the present disclosure.

[0188] In addition, the type of data transmitted in the HARQ process indicated by the first DCI may be: new transmission data, or retransmission data, etc., which is not limited in the present disclosure.

[0189] Optionally, the type of data transmitted in the HARQ process indicated by the first DCI may be determined based on protocol agreement or configuration of the network device and according to the type of the first DCI and the content included in the first DCI.

[0190] For example, the protocol stipulates that: when the type of DCI is PDCCH indicated by G-RNTI and the value of NDI contained in DCI is 0, it indicates that the type of data transmitted in the HARQ process indicated by the DCI is: new transmission data. When the type of DCI is PDCCH indicated by G-RNTI and the value of NDI contained in DCI is 1, it indicates that the type of data transmitted in the HARQ process indicated by the DCI is: retransmission data. When the type of DCI is PDCCH indicated by C-RNTI and the value of NDI contained in DCI is 1, it indicates that the type of data transmitted in the HARQ process indicated by the DCI is: new transmission data. When the type of DCI is PDCCH indicated by C-RNTI and the value of NDI contained in DCI is 0, it indicates that the type of data transmitted in the HARQ process indicated by the DCI is: retransmission data.

[0191] Therefore, when the terminal device receives the first DCI of the PDCCH indicated by G-RNTI-1, and the value of the NDI contained in the first DCI is 1, according to the protocol agreement, it can be determined that the type of data transmitted in the HARQ process indicated by the first DCI is: retransmission data.

[0192] It should be noted that the above examples are merely illustrative and cannot be used as limitations on the methods for determining the type of the first DCI, the content included, and the type of data transmitted in the HARQ process indicated by the first DCI in the embodiments of the present disclosure.

[0193] It can be understood that after determining the type of data transmitted in the HARQ process indicated by the first DCI, the terminal device can process the received data according to the determined type of data.

[0194] For example, when the received data is newly transmitted data for a certain HARQ process, the terminal device can store the newly transmitted data in the cache of the HARQ process. If old data was previously stored in the HARQ process, the old data will be overwritten by the newly transmitted data. Alternatively, when the received data is retransmitted data for a certain HARQ process, the terminal device can combine the retransmitted data with the old data previously stored in the HARQ process and decode them, thereby effectively avoiding data loss.

[0195] In an embodiment of the present disclosure, a terminal device may first receive a first DCI sent by a network device, where the PDCCH identifier corresponding to the first DCI is a broadcast or multicast scheduling identifier. Based on the type of the first DCI and the content contained in the first DCI, the terminal device may determine the type of data transmitted in the HARQ process indicated by the first DCI. This allows the terminal device to accurately determine the type of data transmission, thereby ensuring that the terminal device and the network device have a consistent understanding of the data transmission indication, effectively avoiding data loss and improving data transmission reliability.

[0196] See Figure 3 , Figure 3 This is a flow chart of a data reception processing method provided by an embodiment of the present disclosure, which is configured to be executed by a terminal device. Figure 3 As shown, the method may include but is not limited to the following steps:

[0197] Step 31: Receive a first DCI sent by a network device, where the first DCI is used to indicate that there is data transmission in a HARQ process.

[0198] Optionally, the content included in the first DCI may include at least one of the following: an NDI value or a HARQ process number.

[0199] It should be noted that the specific content and implementation form of the NDI value, HARQ process number, etc. can be referred to other embodiments of the present disclosure and will not be repeated here.

[0200] Step 32. When the PDCCH identifier corresponding to the first DCI is a broadcast or multicast scheduling identifier, in response to the HARQ process number in the first DCI being the same as the HARQ process number in the second DCI and the NDI value in the first DCI being different from the NDI value in the second DCI, it is determined that the data transmitted in the HARQ process indicated by the first DCI is new transmission data, wherein the second DCI is the same as the physical downlink control channel PDCCH corresponding to the first DCI and has the smallest time difference between the receiving times.

[0201] It should be noted that the specific content and implementation form of the PDCCH identifier can be referred to other embodiments of the present disclosure and will not be repeated here.

[0202] Optionally, the same PDCCH may include at least one of the following: the same scheduling identification information of the PDCCH and the same resource configuration information of the PDCCH.

[0203] For example, the scheduling identification information of the PDCCH corresponding to the first DCI and the second DCI is the same, that is, the first DCI and the second DCI both correspond to the PDCCH indicated by G-RNTI-1, or the first DCI and the second DCI can also both correspond to the PDCCH indicated by G-RNTI-2, etc. This disclosure does not limit this.

[0204] It is understandable that the resource configuration information of the PDCCH is the same, which may be the same time domain resource configuration information, such as using the same search space (SS) configuration, etc., and the present disclosure does not limit this.

[0205] Alternatively, the resource configuration information of the PDCCH is the same, and the frequency domain resource configuration information may be the same, for example, the same control resource set (CORESET) configuration is used, etc., which is not limited in the present disclosure.

[0206] For example, the terminal device receives the DCI of the PDCCH indicated by G-RNTI-1 at time t1, and the HARQ process in the DCI is 1 and the NDI value is 1. The terminal device receives the DCI of the PDCCH indicated by C-RNTI-1 at time t2, and the HARQ process in the DCI is 1 and the NDI value is 1. Afterwards, the terminal device receives the first DCI of the PDCCH indicated by G-RNTI-1 at time t3, and the HARQ process in the first DCI is 1 and the NDI value is 0. By comparison, it can be seen that the PDCCH corresponding to the DCI received by the terminal device at time t1 is the same as the PDCCH corresponding to the first DCI, and the HARQ process is also the same, that is, the DCI received at time t1 is the second DCI. Among them, the NDI value in the first DCI is 0, and the NDI value in the second DCI is 1, and the two are different, so it can be determined that the first DCI indicates that the data transmitted in the process with HARQ process 1 is new data.

[0207] Alternatively, the terminal device receives a DCI for the PDCCH indicated by G-RNTI-1 at time t1, wherein the HARQ process in the DCI is 1 and the NDI value is 1. The terminal device receives a DCI for the PDCCH indicated by C-RNTI-1 at time t2, wherein the HARQ process in the DCI is 1 and the NDI value is 1. The terminal device receives a DCI for the PDCCH indicated by G-RNTI-1 at time t3, wherein the HARQ process in the DCI is 1 and the NDI value is 0. Thereafter, the terminal device receives a first DCI for the PDCCH indicated by G-RNTI-1 at time t4, wherein the HARQ process in the first DCI is 1 and the NDI value is 1. By comparison, it can be seen that the PDCCH corresponding to the DCI received by the terminal device at times t3 and t1 is the same as the PDCCH corresponding to the first DCI, and the HARQ process is also the same, and the time interval between the DCI received at time t3 and the reception time of the first DCI is the smallest, thereby determining that the DCI received at time t3 is the second DCI. Among them, the NDI value in the first DCI is 1, and the NDI value in the second DCI is 0, which are different. Therefore, it can be determined that the first DCI indicates that the data transmitted in the HARQ process 1 process is new data.

[0208] It should be noted that the above-mentioned HARQ process number, NDI values, etc. are only for illustrative purposes and cannot be used as a limitation on the HARQ process number, NDI values, and the determination of the type of data transmitted in the HARQ process indicated by the first DCI in the embodiments of the present disclosure.

[0209] Optionally, in a case where the PDCCH identifier corresponding to the first DCI is a broadcast or multicast scheduling identifier, in response to the HARQ process number in the first DCI being the same as the HARQ process number in the second DCI, and the NDI value in the first DCI being the same as the NDI value in the second DCI, it is determined that the data transmitted in the HARQ process indicated by the first DCI is retransmitted data, wherein the second DCI is the same as the physical downlink control channel PDCCH corresponding to the first DCI, and the DCI with the smallest time difference between the receiving times.

[0210] For example, the terminal device receives the DCI of the PDCCH indicated by G-RNTI-1 at time t1, and the HARQ process in the DCI is 1 and the NDI value is 1. The terminal device receives the DCI of the PDCCH indicated by C-RNTI-1 at time t2, and the HARQ process in the DCI is 1 and the NDI value is 1. Afterwards, the terminal device receives the first DCI of the PDCCH indicated by G-RNTI-1 at time t3, and the HARQ process in the first DCI is 1 and the NDI value is 0. By comparison, it can be seen that the PDCCH corresponding to the DCI received by the terminal device at time t1 is the same as the PDCCH corresponding to the first DCI, and the HARQ process is also the same, that is, the DCI received at time t1 is the second DCI. Among them, the value of NDI in the first DCI is the same as the value of NDI in the second DCI, so it can be determined that the first DCI indicates that the data transmitted in the process with HARQ process 1 is retransmitted data.

[0211] It should be noted that the above-mentioned HARQ process number, NDI values, etc. are only for illustrative purposes and cannot be used as a limitation on the HARQ process number, NDI values, and the determination of the type of data transmitted in the HARQ process indicated by the first DCI in the embodiments of the present disclosure.

[0212] In an embodiment of the present disclosure, a terminal device may first receive a first DCI sent by a network device, and then determine the type of data transmitted in the HARQ process indicated by the first DCI based on the HARQ process number and NDI value in a second DCI that has the same PDCCH as the first DCI and has the smallest time difference between reception times, and the HARQ process number and NDI value in the first DCI. Thus, the terminal device can accurately determine the type of data transmission, thereby enabling the terminal device and the network device to have a consistent understanding of the data transmission indication, effectively avoiding data loss and improving data transmission reliability.

[0213] See Figure 4 , Figure 4 This is a flow chart of a data reception processing method provided by an embodiment of the present disclosure, which is configured to be executed by a terminal device. Figure 4 As shown, the method may include but is not limited to the following steps:

[0214] Step 41: Receive a first DCI sent by a network device, where the first DCI is used to indicate that there is data transmission in a HARQ process.

[0215] Optionally, the content included in the first DCI may include at least one of the following: an NDI value or a HARQ process number.

[0216] It should be noted that the value of NDI, HARQ process number and other contents and specific implementation forms can be referred to other embodiments of the present disclosure and will not be repeated here.

[0217] Step 42. When the PDCCH identifier corresponding to the first DCI is a broadcast or multicast scheduling identifier, in response to the HARQ process number in the first DCI being the same as the HARQ process number in the third DCI, and the NDI value in the first DCI being different from the NDI value in the third DCI, it is determined that the data transmitted in the HARQ process indicated by the first DCI is new data, wherein the third DCI has the smallest difference between the receiving time and the receiving time of the first DCI, and the type is a unicast scheduling identifier or a broadcast or multicast scheduling identifier.

[0218] It should be noted that the specific content and implementation form of the PDCCH identifier, unicast scheduling identifier or broadcast or multicast scheduling identifier can be referred to other embodiments of the present disclosure and will not be repeated here.

[0219] For example, the terminal device receives the DCI of the PDCCH indicated by G-RNTI-1 at time t1, and the HARQ process in the DCI is 1 and the NDI value is 1. The terminal device receives the DCI of the PDCCH indicated by C-RNTI-1 at time t2, and the HARQ process in the DCI is 1 and the NDI value is 1. Afterwards, the terminal device receives the first DCI of the PDCCH indicated by G-RNTI-1 at time t3, and the HARQ process in the first DCI is 1 and the NDI value is 0. By comparison, it can be seen that the PDCCH corresponding to the DCI received by the terminal device at time t1 is the same as the PDCCH corresponding to the first DCI, and the HARQ process is also the same, that is, the DCI received at time t1 is the third DCI. Among them, the NDI value in the first DCI is 0, and the NDI value in the third DCI is 1, and the two are different, so it can be determined that the first DCI indicates that the data transmitted in the process with HARQ process 1 is new data.

[0220] Alternatively, the terminal device receives the DCI of the PDCCH indicated by G-RNTI-1 at time t1, and the HARQ process in the DCI is 1 and the value of NDI is 1. The terminal device receives the DCI of the PDCCH indicated by C-RNTI-1 at time t2, and the HARQ process in the DCI is 1 and the value of NDI is 1. Afterwards, the terminal device receives the first DCI of the PDCCH indicated by G-RNTI-1 at time t3, and the HARQ process in the first DCI is 1 and the value of NDI is 0. By comparison, it can be seen that the DCI received by the terminal device at time t2 is the DCI of the unicast scheduling identifier, and the first DCI is the DCI of the broadcast or multicast scheduling identifier, and the DCI received at time t2 has the same HARQ process as the first DCI, that is, the DCI received at time t2 is the third DCI. Among them, the NDI value in the first DCI is 0, and the NDI value in the third DCI is 1, which are different. Therefore, it can be determined that the first DCI indicates that the data transmitted in the HARQ process 1 process is new data.

[0221] It should be noted that the above-mentioned HARQ process number, NDI values, etc. are only for illustrative purposes and cannot be used as a limitation on the HARQ process number, NDI values, and the determination of the type of data transmitted in the HARQ process indicated by the first DCI in the embodiments of the present disclosure.

[0222] Optionally, when the PDCCH identifier corresponding to the first DCI is a broadcast or multicast scheduling identifier, in response to the HARQ process number in the first DCI being the same as the HARQ process number in the third DCI, and the NDI value in the first DCI being the same as the NDI value in the third DCI, it is determined that the data transmitted in the HARQ process indicated by the first DCI is retransmitted data, wherein the third DCI is a DCI with the smallest difference between the receiving time and the receiving time of the first DCI, and the type is a broadcast or multicast scheduling identifier or a unicast scheduling identifier.

[0223] For example, the terminal device receives the DCI of the PDCCH indicated by G-RNTI-1 at time t1, and the HARQ process in the DCI is 1 and the NDI value is 0. The terminal device receives the DCI of the PDCCH indicated by C-RNTI-1 at time t2, and the HARQ process in the DCI is 1 and the NDI value is 1. Afterwards, the terminal device receives the first DCI of the PDCCH indicated by G-RNTI-1 at time t3, and the HARQ process in the first DCI is 1 and the NDI value is 0. By comparison, it can be seen that the PDCCH corresponding to the DCI received by the terminal device at time t1 is the same as the PDCCH corresponding to the first DCI, and the HARQ process is also the same, that is, the DCI received at time t1 is the third DCI. Among them, the value of NDI in the first DCI is the same as the value of NDI in the third DCI, so it can be determined that the first DCI indicates that the data transmitted in the process with HARQ process 1 is retransmitted data.

[0224] Alternatively, the terminal device receives a DCI for the PDCCH indicated by G-RNTI-1 at time t1, wherein the HARQ process in the DCI is 1 and the value of NDI is 1. The terminal device receives a DCI for the PDCCH indicated by C-RNTI-1 at time t2, wherein the HARQ process in the DCI is 1 and the value of NDI is 0. Afterwards, the terminal device receives a first DCI for the PDCCH indicated by G-RNTI-1 at time t3, wherein the HARQ process in the first DCI is 1 and the value of NDI is 0. By comparison, it can be seen that the DCI received by the terminal device at time t2 is a DCI with a unicast scheduling identifier, while the first DCI is a DCI with a broadcast or multicast scheduling identifier. The DCI received at time t2 has the same HARQ process as the first DCI, that is, the DCI received at time t2 is the third DCI. Among them, the value of NDI in the first DCI is the same as the value of NDI in the third DCI, so it can be determined that the first DCI indicates that the data transmitted in the process with HARQ process 1 is retransmitted data.

[0225] It should be noted that the above-mentioned HARQ process number, NDI values, etc. are only for illustrative purposes and cannot be used as a limitation on the HARQ process number, NDI values, and the determination of the type of data transmitted in the HARQ process indicated by the first DCI in the embodiments of the present disclosure.

[0226] In an embodiment of the present disclosure, a terminal device may first receive a first DCI sent by a network device, and the identifier of the PDCCH corresponding to the first DCI is a broadcast or multicast scheduling identifier. Then, based on the HARQ process number and NDI value in the third DCI with the smallest time difference between the reception times corresponding to the first DCI and the type of which is a broadcast or multicast scheduling identifier or a unicast scheduling identifier, and the HARQ process number and NDI value in the first DCI, the type of data transmitted in the HARQ process indicated by the first DCI is determined. Thus, the terminal device can accurately determine the type of data transmission, thereby enabling the terminal device and the network device to have a consistent understanding of the data transmission indication, effectively avoiding data loss and improving the reliability of data transmission.

[0227] See Figure 5 , Figure 5 This is a flow chart of a data reception processing method provided by an embodiment of the present disclosure, which is configured to be executed by a terminal device. Figure 5 As shown, the method may include but is not limited to the following steps:

[0228] Step 51: Receive a first DCI sent by a network device, where the first DCI is used to indicate that there is data transmission in a HARQ process.

[0229] Optionally, the content included in the first DCI may include at least one of the following: an NDI value or a HARQ process number.

[0230] It should be noted that the value of NDI, HARQ process number and other contents and specific implementation forms can refer to other embodiments of the present disclosure and will not be repeated here.

[0231] Step 52. When the PDCCH corresponding to the first DCI is identified as a broadcast or multicast scheduling identifier, in response to the HARQ process number in the first DCI being the same as the HARQ process number in the fourth DCI and the NDI value in the first DCI being different from the NDI value in the fourth DCI, it is determined that the data transmitted in the HARQ process indicated by the first DCI is new data, wherein the fourth DCI is a DCI that is different from the PDCCH corresponding to the first DCI, has the smallest difference between the receiving times, and has the corresponding PDCCH identified as a broadcast or multicast scheduling identifier.

[0232] It should be noted that the specific content and implementation form of the PDCCH identifier, unicast scheduling identifier or broadcast or multicast scheduling identifier can be referred to other embodiments of the present disclosure and will not be repeated here.

[0233] For example, the terminal device receives the DCI of the PDCCH indicated by G-RNTI-2 at time t1, and the HARQ process in the DCI is 1 and the NDI value is 1. The terminal device receives the DCI of the PDCCH indicated by C-RNTI-1 at time t2, and the HARQ process in the DCI is 1 and the NDI value is 1. Afterwards, the terminal device receives the first DCI of the PDCCH indicated by G-RNTI-1 at time t3, and the HARQ process in the first DCI is 1 and the NDI value is 0. By comparison, it can be seen that the DCI received by the terminal device at time t1 has the same identifier as the PDCCH corresponding to the first DCI, and both are broadcast or multicast scheduling identifiers, but the corresponding PDCCH is different from the PDCCH corresponding to the first DCI, but the HARQ process is the same, that is, the DCI received at time t1 is the fourth DCI. Among them, the NDI value in the first DCI is 0, and the NDI value in the fourth DCI is 1, which are different. Therefore, it can be determined that the first DCI indicates that the data transmitted in the HARQ process 1 process is new data.

[0234] It should be noted that the above-mentioned HARQ process number, NDI values, etc. are only for illustrative purposes and cannot be used as a limitation on the HARQ process number, NDI values, and the determination of the type of data transmitted in the HARQ process indicated by the first DCI in the embodiments of the present disclosure.

[0235] Optionally, when the PDCCH corresponding to the first DCI is identified as a broadcast or multicast scheduling identifier, in response to the value of the HARQ process number in the first DCI being the same as the HARQ process number in the fourth DCI, and the value of the NDI in the first DCI being the same as the NDI value in the fourth DCI, it is determined that the data transmitted in the HARQ process indicated by the first DCI is retransmitted data, wherein the fourth DCI is a DCI that is different from the PDCCH corresponding to the first DCI, has the smallest difference between the receiving times, and the corresponding PDCCH is identified as a broadcast or multicast scheduling identifier.

[0236] For example, the terminal device receives the DCI of the PDCCH indicated by G-RNTI-2 at time t1, and the HARQ process in the DCI is 1 and the NDI value is 0. The terminal device receives the DCI of the PDCCH indicated by C-RNTI-1 at time t2, and the HARQ process in the DCI is 1 and the NDI value is 1. Afterwards, the terminal device receives the first DCI of the PDCCH indicated by G-RNTI-1 at time t3, and the HARQ process in the first DCI is 1 and the NDI value is 0. By comparison, it can be seen that the DCI received by the terminal device at time t1 has the same identifier as the PDCCH corresponding to the first DCI, and both are broadcast or multicast scheduling identifiers, but the corresponding PDCCH is different from the PDCCH corresponding to the first DCI, but the HARQ process is the same, that is, the DCI received at time t1 is the fourth DCI. The value of NDI in the first DCI is the same as the value of NDI in the fourth DCI, so it can be determined that the first DCI indicates that the data transmitted in the HARQ process 1 is retransmitted data.

[0237] It should be noted that the above-mentioned HARQ process number, NDI values, etc. are only for illustrative purposes and cannot be used as a limitation on the HARQ process number, NDI values, and the determination of the type of data transmitted in the HARQ process indicated by the first DCI in the embodiments of the present disclosure.

[0238] In an embodiment of the present disclosure, a terminal device may first receive a first DCI sent by a network device, wherein the PDCCH corresponding to the first DCI is identified as a broadcast or multicast scheduling identifier, and the type of data transmitted in the HARQ process indicated by the first DCI may be determined based on the HARQ process number and NDI value in a fourth DCI that is different from the PDCCH corresponding to the first DCI, has the smallest time difference between reception times, and has a corresponding PDCCH identified as a broadcast or multicast scheduling identifier, and the HARQ process number and NDI value in the first DCI. Thus, the terminal device may accurately determine the type of data transmission, thereby enabling the terminal device and the network device to have a consistent understanding of the data transmission indication, effectively avoiding data loss and improving the reliability of data transmission.

[0239] See Figure 6 , Figure 6 This is a flow chart of a data reception processing method provided by an embodiment of the present disclosure, which is configured to be executed by a terminal device. Figure 6 As shown, the method may include but is not limited to the following steps:

[0240] Step 61: Receive a first DCI sent by a network device, where the first DCI is used to indicate that there is data transmission in a HARQ process.

[0241] Optionally, the content included in the first DCI may include at least one of the following: an NDI value or a HARQ process number.

[0242] It should be noted that the value of NDI, HARQ process number and other contents and specific implementation forms can refer to other embodiments of the present disclosure and will not be repeated here.

[0243] Step 62. When the PDCCH corresponding to the first DCI is identified as a broadcast or multicast scheduling identifier, in response to the HARQ process number in the first DCI being the same as the HARQ process number in the fifth DCI, it is determined that the data transmitted in the HARQ process indicated by the first DCI is new data, wherein the fifth DCI is a DCI that is different from the PDCCH corresponding to the first DCI, has the smallest difference between the receiving times, and has a corresponding PDCCH identifier that is a broadcast or multicast scheduling identifier or a unicast scheduling identifier.

[0244] It should be noted that the specific content and implementation form of the PDCCH identifier, unicast scheduling identifier or broadcast or multicast scheduling identifier can be referred to other embodiments of the present disclosure and will not be repeated here.

[0245] For example, the terminal device receives the DCI of the PDCCH indicated by G-RNTI-2 at time t1, and the HARQ process in the DCI is 1. Afterwards, the terminal device receives the first DCI of the PDCCH indicated by G-RNTI-1 at time t2, and the HARQ process in the first DCI is 1. By comparison, it can be seen that the DCI received by the terminal device at time t1 has the same identifier as the PDCCH corresponding to the first DCI, and both are broadcast or multicast scheduling identifiers, but the corresponding PDCCH is different from the PDCCH corresponding to the first DCI, but the HARQ process is the same, that is, the DCI received at time t1 is the fifth DCI, so it can be determined that the first DCI indicates that the data transmitted in the process with HARQ process 1 is new data.

[0246] Alternatively, the terminal device receives a DCI of the PDCCH indicated by C-RNTI-2 at time t1, and the HARQ process in the DCI is 1. Thereafter, the terminal device receives the first DCI of the PDCCH indicated by G-RNTI-1 at time t2, and the HARQ process in the first DCI is 1. By comparison, it can be seen that the PDCCH identifier corresponding to the DCI received by the terminal device at time t1 is a unicast scheduling identifier, while the PDCCH identifier corresponding to the first DCI is a broadcast or multicast scheduling identifier. The two are different, but the HARQ process is the same, that is, the DCI received at time t1 is the fifth DCI, so it can be determined that the first DCI indicates that the data transmitted in the HARQ process 1 process is new data.

[0247] It should be noted that the above-mentioned HARQ process number, NDI values, etc. are only for illustrative purposes and cannot be used as a limitation on the HARQ process number, NDI values, and the determination of the type of data transmitted in the HARQ process indicated by the first DCI in the embodiments of the present disclosure.

[0248] In an embodiment of the present disclosure, a terminal device can first receive the first DCI sent by a network device, and when the identifier of the PDCCH corresponding to the first DCI is a broadcast or multicast scheduling identifier, based on the HARQ process number in the fifth DCI that is different from the PDCCH corresponding to the first DCI, has the smallest time difference between the receiving times, and whose corresponding PDCCH is a broadcast or multicast scheduling identifier or a unicast scheduling identifier, and the HARQ process number in the first DCI, it can be determined that the data transmitted in the HARQ process indicated by the first DCI is new data. In this way, the terminal device can accurately determine the type of data transmission, so that the terminal device and the network device have a consistent understanding of the data transmission indication, effectively avoiding data loss and improving the reliability of data transmission.

[0249] See Figure 7 , Figure 7 This is a flow chart of a data reception processing method provided by an embodiment of the present disclosure, which is configured to be executed by a terminal device. Figure 7 As shown, the method may include but is not limited to the following steps:

[0250] Step 71: Receive a first DCI sent by a network device, where the first DCI is used to indicate that there is data transmission in a HARQ process.

[0251] Optionally, the content included in the first DCI may include at least one of the following: an NDI value or a HARQ process number.

[0252] It should be noted that the value of NDI, HARQ process number and other contents and specific implementation forms can refer to other embodiments of the present disclosure and will not be repeated here.

[0253] Step 72: In response to the first data indicated by the first DCI being retransmitted data corresponding to any historical data, and any historical data having been overwritten or cleared, giving up receiving the first data.

[0254] For example, the terminal device receives a DCI indicated by the PDCCH of G-RNTI-1 at time t1, and the DCI indicates the data transmission of HARQ process 1. At time t2, the terminal device receives a DCI indicated by the PDCCH of C-RNTI-1, and the DCI indicates the new transmission data of HARQ process 1. At time t3, the terminal device receives the first DCI indicated by the PDCCH of G-RNTI-1, and the first DCI indicates that HARQ process 1 retransmits the data scheduled at time t1. That is, the first data received at time t3 is the retransmitted data corresponding to the historical data at time t1, and the historical data has been overwritten at time t2. Therefore, in order to make the terminal device and the network device have a consistent understanding of the data transmission indication and to ensure the reliability of data transmission, the reception of the first data at time t3 can be abandoned.

[0255] In the disclosed embodiment, a terminal device may first receive a first DCI sent by a network device. Thereafter, if the first data indicated by the first DCI is retransmitted data corresponding to any historical data and any historical data has been overwritten or cleared, the terminal device may abandon receiving the first data. Thus, the terminal device can accurately determine the type of data transmission, thereby enabling the terminal device and the network device to have a consistent understanding of the data transmission indication, effectively avoiding data loss and improving the reliability of data transmission.

[0256] See Figure 8 , Figure 8 This is a flow chart of a data reception processing method provided by an embodiment of the present disclosure, which is configured to be executed by a terminal device. Figure 8 As shown, the method may include but is not limited to the following steps:

[0257] Step 81: Receive a first DCI sent by a network device, where the first DCI is used to indicate that there is retransmitted data corresponding to any historical data in a HARQ process.

[0258] Optionally, the content included in the first DCI may include at least one of the following: an NDI value or a HARQ process number.

[0259] It should be noted that the value of NDI, HARQ process number and other contents and specific implementation forms can be referred to other embodiments of the present disclosure and will not be repeated here.

[0260] Step 82: In response to the first data transmission time indicated by the first DCI being after the second data transmission time indicated by the sixth DCI, giving up receiving the first data, wherein the HARQ process number in the sixth DCI is the same as the HARQ process number in the first DCI.

[0261] For example, the terminal device receives a DCI indicated by the PDCCH of G-RNTI-1 at time t1, and the DCI indicates that HARQ process 1 has data to transmit. At time t2, the terminal device receives a DCI indicated by the PDCCH of C-RNTI-1, and the DCI indicates that HARQ process 1 transmits new data at time t3. The terminal device can also simultaneously receive the first DCI indicated by the PDCCH of G-RNTI-1 at time t2, and the first DCI indicates that HARQ process 1 retransmits the data scheduled at time t1 at time t4, that is, the sending time of the first data indicated by the first DCI is t4. By comparison, it can be seen that the HARQ process of the DCI received by the terminal device at time t2 is the same as the HARQ process of the first DCI, that is, the DCI received at time t2 is the sixth DCI, and the sending time of the second data indicated by the sixth DCI is t3. If time t4 is after time t3, the terminal device can give up receiving the first data at time t4.

[0262] It should be noted that the above examples are only illustrative and cannot be used as limitations on the first data and sending time indicated by the first DCI, the second data and sending time indicated by the sixth DCI, etc. in the embodiments of the present disclosure.

[0263] Optionally, the terminal device may also give up receiving the first data when the sending time of the first DCI is after the sending time of the sixth DCI, wherein the HARQ process number in the sixth DCI is the same as the HARQ process number in the first DCI.

[0264] For example, the terminal device receives a DCI indicated by the PDCCH of G-RNTI-1 at time t1, and the DCI indicates that HARQ process 1 has data transmission. At time t2, the terminal device receives a DCI indicated by the PDCCH of C-RNTI, and the DCI indicates the new transmission data of HARQ process 1. At time t3, the terminal device receives the first DCI indicated by the PDCCH of G-RNTI-1, and the first DCI indicates that HARQ process 1 retransmits the data scheduled at time t1. By comparison, it can be seen that the HARQ process of the DCI received by the terminal device at time t2 is the same as the HARQ process of the first DCI, that is, the DCI received at time t2 is the sixth DCI, and the sending time of the sixth DCI is time t2. The sending time of the first DCI is time t3, which is after time t2. In this case, the terminal device can give up receiving the first data at time t3.

[0265] It should be noted that the above examples are only illustrative and cannot be used as limitations on the first data and sending time indicated by the first DCI, the second data and sending time indicated by the sixth DCI, etc. in the embodiments of the present disclosure.

[0266] In an embodiment of the present disclosure, a terminal device may first receive a first DCI sent by a network device, where the first data indicated by the first DCI may be retransmitted data corresponding to any historical data. Subsequently, when the transmission time of the first data indicated by the first DCI is after the transmission time of the second data indicated by the sixth DCI, the terminal device may abandon receiving the first data. This allows the terminal device and the network device to have a consistent understanding of the data transmission indication, effectively avoiding data loss and improving data transmission reliability.

[0267] See Figure 9 , Figure 9 This is a flow chart of a data reception processing method provided by an embodiment of the present disclosure, which is configured to be executed by a terminal device. Figure 9 As shown, the method may include but is not limited to the following steps:

[0268] Step 91: Receive a first DCI sent by a network device, where the first DCI is used to indicate that there is retransmitted data corresponding to any historical data in a HARQ process.

[0269] Optionally, the content included in the first DCI may include at least one of the following: an NDI value or a HARQ process number.

[0270] It should be noted that the value of NDI, HARQ process number and other contents and specific implementation forms can refer to other embodiments of the present disclosure and will not be repeated here.

[0271] Step 92: Receive a first specified rule sent by the network device.

[0272] Optionally, the first specified rule may include any of the following: the receiving priority of newly transmitted data scheduled by unicast is higher than the receiving priority of retransmitted data scheduled by multicast; or the receiving priority of retransmitted data is higher than the receiving priority of newly transmitted data; or the interest priority of the terminal device, etc.

[0273] Optionally, the first specified rule may also be multiple. If there is no conflict among the multiple rules, the terminal device may perform subsequent processing based on the multiple rules.

[0274] It can be understood that if the terminal device receives multiple first specified rules sent by the network device and there are conflicts between the multiple rules, the terminal device can first determine the priority between the rules based on the configuration of the network device or in accordance with the protocol agreement, so that the terminal device can perform subsequent processing based on the priority between the rules.

[0275] Optionally, the first designated rule may also be determined according to an agreement, which is not limited in this disclosure.

[0276] In the present disclosure, step 91 and step 92 may be executed in parallel, or step 91 may be executed first and then step 92, or step 92 may be executed first and then step 91. The present disclosure does not limit this.

[0277] Step 93, in response to the fact that the sending time of the first data indicated by the first DCI and the sending time of the second data indicated by the sixth DCI at least partially overlap, determine the receiving priority of the first data and the second data based on the first specified rule, wherein the HARQ process number in the sixth DCI is the same as the HARQ process number in the first DCI.

[0278] Optionally, the first specified rule is: the newly transmitted data scheduled by unicast has a higher reception priority than the retransmitted data scheduled by multicast. The first data indicated by the first DCI is the retransmitted data scheduled by multicast, and the second data indicated by the sixth DCI is the newly transmitted data scheduled by unicast. If the sending time of the first data indicated by the first DCI partially overlaps with the sending time of the second data indicated by the sixth DCI, the terminal device can determine that the reception priority of the second data is higher than the reception priority of the first data based on the fact that the newly transmitted data scheduled by unicast has a higher reception priority than the retransmitted data scheduled by multicast.

[0279] Optionally, the first specified rule is: retransmitted data has a higher reception priority than newly transmitted data. The first data indicated by the first DCI is retransmitted data, the second data indicated by the sixth DCI is newly transmitted data, and the sending time of the first data indicated by the first DCI partially overlaps with the sending time of the second data indicated by the sixth DCI. Based on the higher reception priority of the retransmitted data than the newly transmitted data, it can be determined that the reception priority of the first data is higher than the reception priority of the second data.

[0280] Optionally, the first specified rule is: the interest priority of the terminal device. For example, the terminal device preferentially receives the retransmitted data scheduled by unicast, and later receives the newly transmitted data scheduled by multicast. The first data indicated by the first DCI is the retransmitted data scheduled by unicast, and the second data indicated by the sixth DCI is the newly transmitted data scheduled by multicast. The sending time of the first data indicated by the first DCI partially overlaps with the sending time of the second data indicated by the sixth DCI. According to the interest priority of the terminal device, it can be determined that the reception priority of the first data is higher than the reception priority of the second data.

[0281] It should be noted that the above examples are merely illustrative and cannot be used as limitations on the first specified rule, first data, second data, etc. in the embodiments of the present disclosure.

[0282] In an embodiment of the present disclosure, a terminal device may first receive a first DCI sent by a network device, where the first DCI is used to indicate that there is retransmitted data corresponding to any historical data in a HARQ process. If the first data indicated by the first DCI is retransmitted data corresponding to any historical data, and the transmission time of the first data at least partially overlaps with the transmission time of the second data indicated by a sixth DCI, the reception priority of the first data and the second data may be determined based on a first specified rule, and the HARQ process number in the sixth DCI is the same as the HARQ process number in the first DCI. Thus, the terminal device and the network device can have a consistent understanding of the data transmission indication, effectively avoiding data loss and improving the reliability of data transmission.

[0283] See Figure 10 , Figure 10 This is a flow chart of a data reception processing method provided by an embodiment of the present disclosure, which is configured to be executed by a terminal device. Figure 10 As shown, the method may include but is not limited to the following steps:

[0284] Step 101: In response to the fact that the sending time of the first DCI is after the sending time of the seventh DCI, giving up receiving the first data indicated by the first DCI.

[0285] For example, the network device sends the first DCI indicated by the PDCCH of G-RNTI-1 at time t1, and the first data indicated by the first DCI is the new transmission data. At time t2, the network device sends the seventh DCI indicated by the PDCCH of C-RNTI-1. If time t1 is after time t2, the terminal device can give up receiving the first data indicated by the first DCI.

[0286] It should be noted that the above examples are merely illustrative and cannot be used as limitations on the first data and sending time indicated by the first DCI, the sending time of the seventh DCI, etc. in the embodiments of the present disclosure.

[0287] Optionally, the terminal device may also determine the reception priority of the first data and the third data indicated by the seventh DCI based on the configuration information sent by the network device.

[0288] For example, if the terminal device receives configuration information sent by the network device indicating that the reception priority of newly transmitted data is higher than the reception priority of retransmitted data, and if the type of first data indicated by the first DCI is newly transmitted data and the type of third data indicated by the seventh DCI is retransmitted data, it can be determined based on the received configuration information that the reception priority of the first data is higher than the reception priority of the third data.

[0289] It should be noted that the above examples are merely illustrative and cannot be used as limitations on the first data indicated by the first DCI, the third data indicated by the seventh DCI, etc. in the embodiments of the present disclosure.

[0290] Optionally, the terminal device may also determine the reception priority of the first data and the third data indicated by the seventh DCI based on the second specified rule.

[0291] The second specified rule may be sent by the network device to the terminal device, or may be determined by the terminal device according to a protocol agreement, which is not limited in the present disclosure.

[0292] Optionally, the second specified rule may include any one of the following: the receiving priority of newly transmitted data scheduled by unicast is higher than the receiving priority of newly transmitted data scheduled by multicast; or the interest priority of the terminal device.

[0293] Optionally, the second specified rule is: newly transmitted data scheduled by unicast has a higher reception priority than newly transmitted data scheduled by multicast. The type of the first data indicated by the first DCI is newly transmitted data scheduled by multicast, and the type of the third data indicated by the seventh DCI is newly transmitted data scheduled by unicast. Therefore, according to the second specified rule, it can be determined that the reception priority of the third data indicated by the seventh DCI is higher than the reception priority of the first data indicated by the first DCI.

[0294] Optionally, the second specified rule is: interest priority of the terminal device. For example, the terminal device preferentially receives newly transmitted data scheduled by multicast, and later receives newly transmitted data scheduled by unicast. The first data indicated by the first DCI is newly transmitted data scheduled by unicast, and the third data indicated by the seventh DCI is newly transmitted data scheduled by multicast. Therefore, according to the second specified rule, it can be determined that the reception priority of the third data indicated by the seventh DCI is higher than the reception priority of the first data indicated by the first DCI.

[0295] It should be noted that the above examples are merely illustrative and cannot be used as limitations on the first data indicated by the first DCI, the third data indicated by the seventh DCI, etc. in the embodiments of the present disclosure.

[0296] Step 102: In response to the terminal device giving up receiving the data transmitted in the HARQ process indicated by the first DCI, feedback information is returned to the network device, wherein the feedback information is used to indicate to the network device that the reception of the data transmitted in the HARQ process indicated by the first DCI has failed.

[0297] For example, the terminal device gives up receiving the data transmitted in the HARQ process 1 indicated by the first DCI, and can return a feedback message to the network device indicating that the data transmission in the HARQ process 1 indicated by the first DCI has failed to be received, etc. This disclosure does not limit this.

[0298] Optionally, in order to save network resources, the terminal device may also give up returning feedback information to the network device after giving up receiving data transmitted in the HARQ process indicated by the first DCI.

[0299] For example, the terminal device gives up receiving the data transmitted in the HARQ process 2 indicated by the first DCI, and may not return a feedback message of the failure to receive the data transmitted in the HARQ process 2 indicated by the first DCI to the network device, etc. This disclosure does not limit this.

[0300] In the embodiment of the present disclosure, if the first DCI transmission time is after the seventh DCI transmission time, the terminal device may abandon receiving the first data indicated by the first DCI and then return feedback information to the network device indicating a failure to receive the data transmitted in the HARQ process indicated by the first DCI. This allows the terminal device and the network device to have a consistent understanding of the data transmission indication, effectively avoiding data loss and improving data transmission reliability.

[0301] See Figure 11 , Figure 11 This is a flow chart of a data reception processing method provided by an embodiment of the present disclosure, which is configured to be executed by a network device. Figure 11As shown, the method may include but is not limited to the following steps:

[0302] Step 111: In response to data transmission in a hybrid automatic repeat request (HARQ) process, determine the type of first downlink control information (DCI) corresponding to the HARQ process and the content contained in the first DCI according to the type of data to be transmitted.

[0303] Optionally, the type of the first DCI may be determined according to the RNTI corresponding to the first DCI.

[0304] It should be noted that the type of the first DCI and the specific implementation of determining the type of the first DCI can refer to the description of other embodiments of the present disclosure and will not be repeated here.

[0305] Optionally, the content included in the first DCI may include at least one of the following: a value of the new data indication NDI or a HARQ process number.

[0306] It should be noted that the content and specific implementation form contained in the first DCI can refer to the description of other embodiments of the present disclosure and will not be repeated here.

[0307] Specifically, when the network device determines that HARQ process 1 in the DCI of the PDCCH indicated by G-RNTI-1 has new data at time t3, the network device can determine that the type of the first DCI corresponding to HARQ process 1 is the PDCCH indicated by G-RNTI-1. Thereafter, the network device can determine the value of the NDI corresponding to HARQ process 1 in the DCI of the PDCCH indicated by G-RNTI-1 at time t3 based on the value of the NDI corresponding to HARQ process 1 in the DCI of the PDCCH indicated by G-RNTI-1 sent at previous times.

[0308] For example, in the PDCCH DCI indicated by G-RNTI-1 sent at time t2, the NDI value corresponding to HARQ process 1 is 1, and the DCI at time t2 indicates retransmitted data. However, the data to be transmitted at time t3 is new data. Therefore, the network device can determine that the NDI value corresponding to HARQ process 1 in the PDCCH DCI indicated by G-RNTI-1 at time t3 is 0.

[0309] Alternatively, when the network device determines that HARQ process 1 in the DCI of the PDCCH indicated by G-RNTI-1 at time t3 has retransmitted data, the network device can determine that the type of the first DCI corresponding to HARQ process 1 is the PDCCH indicated by G-RNTI-1. Thereafter, the network device can determine the value of the NDI corresponding to HARQ process 1 in the DCI of the PDCCH indicated by G-RNTI-1 at time t3 based on the value of the NDI corresponding to HARQ process 1 in the DCI of the PDCCH indicated by G-RNTI-1 at each previous time.

[0310] For example, if the NDI value for HARQ process 1 in the PDCCH DCI indicated by G-RNTI-1 at time t2 is 1, and the DCI at time t2 indicates retransmitted data, and the data to be transmitted at time t3 is also retransmitted data, the network device can determine that the NDI value for HARQ process 1 in the PDCCH DCI indicated by G-RNTI-1 at time t3 is 1.

[0311] It should be noted that the above examples are merely illustrative and cannot be used as limitations on the type of data to be transmitted, the type of the first DCI, and the content contained in the first DCI in the embodiments of the present disclosure.

[0312] It should be noted that the network device determines the specific implementation form of the type of the first DCI corresponding to the HARQ process and the content included in the first DCI according to the type of data to be transmitted. This can be achieved by referring to the way in which the terminal device determines the type of data transmitted in the HARQ process according to the type of the first DCI and the content included in the first DCI in other embodiments of the present disclosure, and performing the reverse operation. It will not be repeated here.

[0313] Step 112: Send a first DCI to the terminal device, where the first DCI is used to indicate that there is data transmission in the HARQ process.

[0314] It is understood that after determining the type of the first DCI corresponding to the HARQ process and the content contained in the first DCI, the network device can send the first DCI to the terminal device, so that the terminal device can determine the type of data transmitted in the HARQ process based on the first DCI. In this way, the terminal device and the network device can have a consistent understanding of the data transmission indication, thereby reducing data loss and improving the reliability of data transmission.

[0315] In an embodiment of the present disclosure, when data is being transmitted in a HARQ process, a network device can determine the type of first downlink control information (DCI) corresponding to the HARQ process and the content contained in the first DCI based on the type of data to be transmitted. The device then sends the first DCI to a terminal device, where the first DCI indicates that data is being transmitted in the hybrid automatic repeat request (HARQ) process. This allows the terminal device and the network device to have a consistent understanding of the data transmission indication, effectively preventing data loss and improving data transmission reliability.

[0316] See Figure 12 , Figure 12 This is a flow chart of a data reception processing method provided by an embodiment of the present disclosure, which is configured to be executed by a network device. Figure 12 As shown, the method may include but is not limited to the following steps:

[0317] Step 121: Send a first specified rule to the terminal device, wherein the first specified rule is used to indicate to the terminal device the reception priority of the newly transmitted data and the retransmitted data transmitted based on the same HARQ process.

[0318] Optionally, the first specified rule may include any one of the following: the receiving priority of newly transmitted data scheduled by unicast is higher than the receiving priority of retransmitted data scheduled by multicast; or the receiving priority of retransmitted data is higher than the receiving priority of newly transmitted data; or the interest priority of the terminal device.

[0319] It should be noted that the operations and corresponding effects performed by the terminal device in the present disclosure based on the first specified rules can refer to the descriptions of other embodiments of the present disclosure and will not be repeated here.

[0320] Step 122: Send a second specified rule to the terminal device, wherein the second specified rule is used to indicate to the terminal device the reception priority of multiple newly transmitted data transmitted based on the same HARQ process.

[0321] Optionally, the second specified rule may include any one of the following: the receiving priority of newly transmitted data scheduled by unicast is higher than the receiving priority of newly transmitted data scheduled by multicast; or the interest priority of the terminal device.

[0322] It should be noted that the operations and corresponding effects performed by the terminal device in the present disclosure based on the second specified rules can refer to the descriptions of other embodiments of the present disclosure and will not be repeated here.

[0323] Step 123: In response to data transmission in the HARQ process, the type of first downlink control information DCI corresponding to the HARQ process and the content included in the first DCI are determined according to the type of the data to be transmitted.

[0324] Optionally, the type of the first DCI may be determined according to the RNTI corresponding to the first DCI.

[0325] It should be noted that the type of the first DCI and the specific implementation of determining the type of the first DCI can refer to the description of other embodiments of the present disclosure and will not be repeated here.

[0326] Optionally, the content included in the first DCI may include at least one of the following: a value of the new data indication NDI or a HARQ process number.

[0327] It should be noted that the content and specific implementation form contained in the first DCI can refer to the description of other embodiments of the present disclosure and will not be repeated here.

[0328] In the present disclosure, step 121, step 122 and step 123 can be executed in parallel, or step 121 can be executed first and then step 122, and then step 123, or step 122 can be executed first, then step 121, and then step 123, or step 123 can be executed first, then step 121, and then step 122, and so on. The present disclosure does not limit this.

[0329] Step 124: Send a first DCI to the terminal device, where the first DCI is used to indicate that there is data transmission in the hybrid automatic repeat request HARQ process.

[0330] In an embodiment of the present disclosure, a network device can send a first specified rule and a second specified rule to a terminal device so that the terminal device can receive data in an orderly manner. Furthermore, when data is being transmitted in a HARQ process, the network device can determine the type of first downlink control information (DCI) corresponding to the HARQ process and the content contained in the first DCI based on the type of data to be transmitted, and then send the first DCI to the terminal device. This allows the terminal device and the network device to have a consistent understanding of the data transmission indication, effectively preventing data loss and improving data transmission reliability.

[0331] In the embodiments provided above, the methods provided in the embodiments of the present disclosure are described from the perspectives of network devices and terminal devices, respectively. To implement the various functions provided in the methods provided in the embodiments of the present disclosure, the network devices and terminal devices may include hardware structures and software modules, and the aforementioned functions may be implemented in the form of hardware structures, software modules, or hardware structures and software modules. Certain of the aforementioned functions may be implemented in the form of hardware structures, software modules, or hardware structures and software modules.

[0332] See Figure 13 , which is a structural diagram of a communication device 130 provided in an embodiment of the present disclosure. Figure 13The communication device 130 shown may include a transceiver module 1301 and a processing module 1302 .

[0333] The transceiver module 1301 may include a sending module and / or a receiving module. The sending module is used to implement a sending function, and the receiving module is used to implement a receiving function. The transceiver module 1301 may implement a sending function and / or a receiving function.

[0334] Communication device 130 is a terminal device:

[0335] The transceiver module 1301 is configured to receive first downlink control information DCI sent by a network device, wherein the first DCI is used to indicate that there is data transmission in a hybrid automatic repeat request HARQ process;

[0336] The processing module 1302 is used to determine the type of data transmitted in the HARQ process indicated by the first DCI in response to the physical downlink control channel PDCCH identifier corresponding to the first DCI being a broadcast or multicast scheduling identifier, according to the type of the first DCI and the content contained in the first DCI.

[0337] Optionally, the processing module 1302 is further configured to determine the type of the first DCI according to a radio network temporary identifier RNTI corresponding to the first DCI.

[0338] Optionally, the content included in the first DCI includes at least one of the following: a value of a new data indication NDI or a HARQ process number.

[0339] Optionally, the processing module 1302 is specifically configured to:

[0340] In response to the HARQ process number in the first DCI being the same as the HARQ process number in the second DCI, and the NDI value in the first DCI being different from the NDI value in the second DCI, determining that the data transmitted in the HARQ process indicated by the first DCI is new data;
