[0028] The embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0029] Currently, the NR system supports configuring semi-static transmission for terminal devices. Semi-static transmission can only be used after being activated by activating DCI (a specific dedicated DCI, which is designed differently from the DCI for scheduling data). For example, after the semi-static transmission is activated, semi-static transmission data can be received at the (periodic) position of the semi-static transmission, and a semi-static release control signaling is supported to simultaneously release at least two activated semi-static transmissions. The semi-static transmission here can be semi-static transmission of downlink data (also called Semi-Persistent Scheduling Physical Downlink Shared Channel (SPS PDSCH)) or semi-static transmission of uplink data (also called Configured Grant Physical Uplink Shared Channel (CG PUSCH)).

[0030] Currently in the NR system, an activated DCI can activate a semi-static transmission. At the same time, the NR system also supports at least 2 transmissions of different priorities, such as high-priority transmission and low-priority transmission. For a semi-static transmission, it supports configuring a semi-static transmission for the terminal device through Radio Resource Control (RRC) signaling, and uses RRC signaling to clearly indicate the priority of the semi-static transmission, that is, high or low priority. In addition, the NR system also supports two different priority levels of Hybrid Automatic Repeat request-Acknowledgement (HARQ-ACK) codebook transmissions, such as high-priority HARQ-ACK codebook transmissions and low-priority HARQ-ACK codebook transmissions. The reliability and latency required for HARQ-ACK transmissions of different priorities are different.

[0031] Therefore, when designing activation of DCI and semi-static transmission, the following four problems may still exist:

[0032] 1. An activation DCI is used to activate at least two semi-static transmissions at the same time, especially when the semi-static transmissions are configured with priorities by RRC signaling, what rules should the activation DCI follow to activate at least two semi-static transmissions at the same time?

[0033] 2. If a deactivation DCI (used to deactivate an activated semi-static transmission, which is a specific DCI whose design is different from the DCI for scheduling data) simultaneously deactivates at least two activated semi-static transmissions, how is the HARQ-ACK corresponding to this deactivation DCI fed back in the HARQ-ACK codebook (for example, when the HARQ-ACK codebook is a semi-static codebook, and when the HARQ-ACK codebook is a dynamic codebook)?

[0034] 3. Since different semi-static transmissions have different priorities, how can a deactivated DCI deactivate at least two activated semi-static transmissions to simplify the corresponding subsequent HARQ-ACK codebook and feedback (for example, the generation and transmission of the HARQ-ACK corresponding to the deactivated DCI are simplified, and for example, how to determine the priority of the HARQ-ACK corresponding to the deactivated DCI)?

[0035] 4. When a deactivation DCI deactivates at least two activated semi-static transmissions, how is the priority of the HARQ-ACK corresponding to the deactivated DCI determined (especially if the at least two semi-static transmissions deactivated by the deactivation DCI are configured with different or same priorities by RRC signaling)?

[0036] The embodiment of the present application provides a mobile communication network (including but not limited to the fifth generation mobile communication network (5th-Generation, 5G)), the network architecture of which may include network-side devices (such as one or more types of base stations, transmission nodes, access nodes (AP, Access Point), relays, Node B (Node B, NB), terrestrial radio access (UTRA, Universal Terrestrial Radio Access), evolved terrestrial radio access (EUTRA, Evolved Universal Terrestrial Radio Access), etc.) and terminal devices (user equipment (User Equipment, UE), user equipment data card, relay, mobile device, etc.). In the embodiment of the present application, a data processing method, a communication node and a computer-readable storage medium that can be run on the above network architecture are provided, which can associate control information with semi-static transmission to improve the efficiency and stability of transmission.

[0037] The data processing method, communication node and their technical effects are described below.

[0038] Figure 1 A schematic diagram of a data processing method provided by an embodiment is shown. Figure 1 As shown, the method provided in this embodiment is applicable to the first communication node, and the method includes the following steps.

[0039] S110. The first communication node sends first control information to the second communication node, where the first control information is used to activate or deactivate at least one semi-static transmission, and the first control information is associated with the first semi-static transmission, and the at least one semi-static transmission includes the first semi-static transmission.

[0040] In one embodiment, when the first control information is used to deactivate at least two semi-static transmissions and the at least two semi-static transmissions have the same priority, a position of the HARQ-ACK of the first control information in the semi-static HARQ-ACK codebook is associated with a physical downlink shared channel (PDSCH) of the first semi-static transmission;

[0041] Among them, the index of the first semi-static transmission is the smallest among the indices of all deactivated semi-static transmissions; or, the index of the first semi-static transmission is the largest among the indices of all deactivated semi-static transmissions; or, the first semi-static transmission is indicated by an indication information carried by the first control information, wherein the indication information is the PDSCH time domain resource allocation information corresponding to at least two deactivated semi-static transmissions, or is the sequential index value of the index values ​​of at least two deactivated semi-static transmissions in ascending or descending order.

[0042] For example, the first control information is used to deactivate semi-static transmission 1, semi-static transmission 2, and semi-static transmission 3, the index of semi-static transmission 1 is 1, the index of semi-static transmission 2 is 2, and the index of semi-static transmission 3 is 3. Then, the first semi-static transmission may be semi-static transmission 1 with the smallest index, or may be semi-static transmission 3 with the largest index. Of course, the first semi-static transmission may also be indicated by an indication information carried by the first control information.

[0043] In one embodiment, when the first control information is used to deactivate at least two semi-static transmissions, and the at least two semi-static transmissions have different priorities, the position of the HARQ-ACK of the first control information in the semi-static HARQ-ACK codebook is associated with the PDSCH of the first semi-static transmission;

[0044] Among them, the first semi-static transmission is the semi-static transmission with the highest priority among all deactivated semi-static transmissions; or, the first semi-static transmission is the semi-static transmission with the lowest priority among all deactivated semi-static transmissions; or, the first semi-static transmission is the semi-static transmission with the highest priority among all deactivated semi-static transmissions, and the index of the first semi-static transmission is the smallest among the indices of all deactivated semi-static transmissions with the highest priority; or, the first semi-static transmission is the semi-static transmission with the highest priority among all deactivated semi-static transmissions, and the index of the first semi-static transmission is the largest among the indices of all deactivated semi-static transmissions with the highest priority; or, the first semi-static transmission is the semi-static transmission with the lowest priority among all deactivated semi-static transmissions, and the index of the first semi-static transmission is the smallest among the indices of all deactivated semi-static transmissions with the highest priority; or, the first semi-static transmission is the semi-static transmission with the lowest priority among all deactivated semi-static transmissions, and the index of the first semi-static transmission is the largest among the indices of all deactivated semi-static transmissions with the highest priority.

[0045] In one embodiment, when at least two semi-static transmissions have different priorities, the first communication node configures an index value of a high-priority semi-static transmission that is smaller than an index value of a low-priority semi-static transmission, or the first communication node configures an index value of a high-priority semi-static transmission that is larger than an index value of a low-priority semi-static transmission.

[0046] In one embodiment, when the first control information is used to deactivate at least two semi-static transmissions, the priority of the HARQ-ACK of the first control information is confirmed in one of the following ways:

[0047] Confirmation according to the priority indication information carried by the first control information; or,

[0048] Confirmation based on the priority of the semi-static transmission with the highest priority configured by RRC signaling among the at least two deactivated semi-static transmissions; or,

[0049] Confirming the priority of the higher one of the priority indication information carried by the first control information and the priority of the at least two deactivated semi-static transmissions configured by RRC signaling, wherein if the first control information does not carry the priority indication information, the priority indication information carried by the first control information is considered to be a low priority; or,

[0050] If the first control information carries priority indication information, confirm according to the priority indication information carried by the first control information; otherwise, if the at least two deactivated semi-static transmissions are configured with priorities by RRC signaling, confirm according to the higher priority among the priorities configured by RRC signaling in the at least two deactivated semi-static transmissions; otherwise, the HARQ-ACK of the first control information is confirmed as a low priority; or,

[0051] If the at least two deactivated semi-static transmissions are configured with priorities by RRC signaling, confirmation is performed according to a higher priority among the priorities configured by RRC signaling in the at least two deactivated semi-static transmissions; otherwise, the HARQ-ACK of the first control information is confirmed as a low priority;

[0052] If a semi-static transmission is not configured with a priority by RRC signaling, it is confirmed that the semi-static transmission is configured with a low priority by RRC signaling.

[0053] In one embodiment, when the first control information is used to activate at least two semi-static transmissions and the at least two semi-static transmissions have different priorities, the priority indication information carried by the first control information is valid and applicable to the at least two semi-static transmissions; or,

[0054] When the first control information is used to activate at least two semi-static transmissions, and the at least two semi-static transmissions have different priorities, the priority indication information carried by the first control information is invalid and is not applicable to the at least two semi-static transmissions; or,

[0055] When the first control information is used to activate at least two semi-static transmissions, and there is a semi-static transmission whose priority is not configured by RRC signaling among the at least two semi-static transmissions, the priority of the semi-static transmission whose priority is not configured by RRC signaling is confirmed according to the priority indication information carried by the first control information; or,

[0056] When the first control information is used to activate at least two semi-static transmissions, the at least two semi-static transmissions are required to have the same RRC signaling configured priority. The priority indicated by the priority indication information carried by the first control information allows following or modifying the RRC signaling configured priority of at least two semi-static transmissions.

[0057] In one embodiment, when the first control information is used to activate a semi-static transmission and a priority of the semi-static transmission is configured by RRC signaling, if the first control information does not carry priority indication information, the priority of the semi-static transmission is confirmed according to the priority configured by RRC signaling; or,

[0058] When the first control information is used to activate a semi-static transmission and the priority of the semi-static transmission is not configured by RRC signaling, if the first control information does not carry priority indication information, the priority of the semi-static transmission is confirmed according to the high priority or the low priority; or,

[0059] When the first control information is used to activate a semi-static transmission and a priority of the semi-static transmission is configured by RRC signaling, if the first control information carries priority indication information, the priority of the semi-static transmission is confirmed according to the priority indication information carried by the first control information; or,

[0060] When the first control information is used to activate a semi-static transmission and the priority of the semi-static transmission is not configured by RRC signaling, if the first control information carries priority indication information, the priority of the semi-static transmission is confirmed according to the priority indication information carried by the first control information; or,

[0061] When the first control information is used to activate a semi-static transmission and a semi-static transmission is configured with a priority by RRC signaling, if the first control information carries priority indication information, the priority of the semi-static transmission is confirmed according to the higher or lower of the priority indication information carried by the first control information and the priority configured by RRC signaling.

[0062] In one embodiment, when the first control information is used to deactivate a semi-static transmission, and the semi-static transmission is configured with a priority by RRC signaling, if the first control information does not carry priority indication information, the priority of the semi-static transmission is confirmed according to the priority configured by RRC signaling; or,

[0063] When the first control information is used to deactivate a semi-static transmission and the semi-static transmission is not configured with a priority by RRC signaling, if the first control information does not carry priority indication information, the priority of the semi-static transmission is confirmed according to a high priority or a low priority; or,

[0064] When the first control information is used to deactivate a semi-static transmission and the semi-static transmission is configured with a priority by RRC signaling, if the first control information carries priority indication information, the priority of the semi-static transmission is confirmed according to the priority indication information carried by the first control information; or,

[0065] When the first control information is used to deactivate a semi-static transmission and the semi-static transmission is not configured with a priority by RRC signaling, if the first control information carries priority indication information, the priority of the semi-static transmission is confirmed according to the priority indication information carried by the first control information; or,

[0066] When the first control information is used to deactivate a semi-static transmission and a semi-static transmission is configured with a priority by RRC signaling, if the first control information carries priority indication information, the priority of the semi-static transmission is confirmed according to the higher or lower of the priority indication information carried by the first control information and the priority configured by RRC signaling.

[0067] Figure 2 A flow chart of another data processing method provided by an embodiment is shown. Figure 2 As shown, the method provided in this embodiment is applicable to the second communication node, and the method includes the following steps.

[0068] S210. The second communication node receives first control information sent by the first communication node, where the first control information is used to activate or deactivate at least one semi-static transmission, and the first control information is associated with the first semi-static transmission, and the at least one semi-static transmission includes the first semi-static transmission.

[0069] In one embodiment, when the first control information is used to deactivate at least two semi-static transmissions and the at least two semi-static transmissions have the same priority, the position of the hybrid automatic repeat request-acknowledgement information HARQ-ACK of the first control information in the semi-static HARQ-ACK codebook is associated with the physical downlink shared channel PDSCH of the first semi-static transmission;

[0070] Among them, the index of the first semi-static transmission is the smallest among the indices of all deactivated semi-static transmissions; or, the index of the first semi-static transmission is the largest among the indices of all deactivated semi-static transmissions; or, the first semi-static transmission is indicated by an indication information carried by the first control information, wherein the indication information is the PDSCH time domain resource allocation information corresponding to at least two deactivated semi-static transmissions, or is the sequential index value of the index values ​​of at least two deactivated semi-static transmissions in ascending or descending order.

[0071] For example, the first control information is used to deactivate semi-static transmission 1, semi-static transmission 2, and semi-static transmission 3, the index of semi-static transmission 1 is 1, the index of semi-static transmission 2 is 2, and the index of semi-static transmission 3 is 3. Then, the first semi-static transmission may be semi-static transmission 1 with the smallest index, or may be semi-static transmission 3 with the largest index. Of course, the first semi-static transmission may also be indicated by an indication information carried by the first control information.

[0072] In one embodiment, when the first control information is used to deactivate at least two semi-static transmissions, and the at least two semi-static transmissions have different priorities, the position of the HARQ-ACK of the first control information in the semi-static HARQ-ACK codebook is associated with the PDSCH of the first semi-static transmission;

[0073] Among them, the first semi-static transmission is the semi-static transmission with the highest priority among all deactivated semi-static transmissions; or, the first semi-static transmission is the semi-static transmission with the lowest priority among all deactivated semi-static transmissions; or, the first semi-static transmission is the semi-static transmission with the highest priority among all deactivated semi-static transmissions, and the index of the first semi-static transmission is the smallest among the indices of all deactivated semi-static transmissions with the highest priority; or, the first semi-static transmission is the semi-static transmission with the highest priority among all deactivated semi-static transmissions, and the index of the first semi-static transmission is the largest among the indices of all deactivated semi-static transmissions with the highest priority; or, the first semi-static transmission is the semi-static transmission with the lowest priority among all deactivated semi-static transmissions, and the index of the first semi-static transmission is the smallest among the indices of all deactivated semi-static transmissions with the highest priority; or, the first semi-static transmission is the semi-static transmission with the lowest priority among all deactivated semi-static transmissions, and the index of the first semi-static transmission is the largest among the indices of all deactivated semi-static transmissions with the highest priority.

[0074] In one embodiment, when at least two semi-static transmissions have different priorities, the index value of the high-priority semi-static transmission is smaller than the index value of the low-priority semi-static transmission, or the index value of the high-priority semi-static transmission is greater than the index value of the low-priority semi-static transmission.

[0075] In one embodiment, when the first control information is used to deactivate at least two semi-static transmissions, the priority of the HARQ-ACK of the first control information is confirmed in one of the following ways:

[0076] Confirmation according to the priority indication information carried by the first control information; or,

[0077] Confirmation based on the priority of the semi-persistent transmission with the highest priority configured by the radio resource control RRC signaling among the at least two deactivated semi-persistent transmissions; or,

[0078] Confirming the priority of the higher one of the priority indication information carried by the first control information and the priority of the at least two deactivated semi-static transmissions configured by RRC signaling, wherein if the first control information does not carry the priority indication information, the priority indication information carried by the first control information is considered to be a low priority; or,

[0079] If the first control information carries priority indication information, confirm according to the priority indication information carried by the first control information; otherwise, if the at least two deactivated semi-static transmissions are configured with priorities by RRC signaling, confirm according to the higher priority among the priorities configured by RRC signaling in the at least two deactivated semi-static transmissions; otherwise, the HARQ-ACK of the first control information is confirmed as a low priority; or,

[0080] If the at least two deactivated semi-static transmissions are configured with priorities by RRC signaling, confirmation is performed according to a higher priority among the priorities configured by RRC signaling in the at least two deactivated semi-static transmissions; otherwise, the HARQ-ACK of the first control information is confirmed as a low priority;

[0081] If a semi-static transmission is not configured with a priority by RRC signaling, it is confirmed that the semi-static transmission is configured with a low priority by RRC signaling.

[0082] In one embodiment, when the first control information is used to activate at least two semi-static transmissions and the at least two semi-static transmissions have different priorities, the priority indication information carried by the first control information is valid and applicable to the at least two semi-static transmissions; or,

[0083] When the first control information is used to activate at least two semi-static transmissions, and the at least two semi-static transmissions have different priorities, the priority indication information carried by the first control information is invalid and is not applicable to the at least two semi-static transmissions; or,

[0084] When the first control information is used to activate at least two semi-static transmissions, and there is a semi-static transmission whose priority is not configured by RRC signaling among the at least two semi-static transmissions, the priority of the semi-static transmission whose priority is not configured by RRC signaling is confirmed according to the priority indication information carried by the first control information; or,

[0085] When the first control information is used to activate at least two semi-static transmissions, the at least two semi-static transmissions are required to have the same RRC signaling configured priority. The priority indicated by the priority indication information carried by the first control information allows following or modifying the RRC signaling configured priority of at least two semi-static transmissions.

[0086] In one embodiment, when the first control information is used to activate a semi-static transmission and a priority of the semi-static transmission is configured by RRC signaling, if the first control information does not carry priority indication information, the priority of the semi-static transmission is confirmed according to the priority configured by RRC signaling; or,

[0087] When the first control information is used to activate a semi-static transmission and the priority of the semi-static transmission is not configured by RRC signaling, if the first control information does not carry priority indication information, the priority of the semi-static transmission is confirmed according to the high priority or the low priority; or,

[0088] When the first control information is used to activate a semi-static transmission and a priority of the semi-static transmission is configured by RRC signaling, if the first control information carries priority indication information, the priority of the semi-static transmission is confirmed according to the priority indication information carried by the first control information; or,

[0089] When the first control information is used to activate a semi-static transmission and the priority of the semi-static transmission is not configured by RRC signaling, if the first control information carries priority indication information, the priority of the semi-static transmission is confirmed according to the priority indication information carried by the first control information; or,

[0090] When the first control information is used to activate a semi-static transmission and a semi-static transmission is configured with a priority by RRC signaling, if the first control information carries priority indication information, the priority of the semi-static transmission is confirmed according to the higher or lower of the priority indication information carried by the first control information and the priority configured by RRC signaling.

[0091] In one embodiment, when the first control information is used to deactivate a semi-static transmission, and the semi-static transmission is configured with a priority by RRC signaling, if the first control information does not carry priority indication information, the priority of the semi-static transmission is confirmed according to the priority configured by RRC signaling; or,

[0092] When the first control information is used to deactivate a semi-static transmission and the semi-static transmission is not configured with a priority by RRC signaling, if the first control information does not carry priority indication information, the priority of the semi-static transmission is confirmed according to a high priority or a low priority; or,

[0093] When the first control information is used to deactivate a semi-static transmission and the semi-static transmission is configured with a priority by RRC signaling, if the first control information carries priority indication information, the priority of the semi-static transmission is confirmed according to the priority indication information carried by the first control information; or,

[0094] When the first control information is used to deactivate a semi-static transmission and the semi-static transmission is not configured with a priority by RRC signaling, if the first control information carries priority indication information, the priority of the semi-static transmission is confirmed according to the priority indication information carried by the first control information; or,

[0095] When the first control information is used to deactivate a semi-static transmission and a semi-static transmission is configured with a priority by RRC signaling, if the first control information carries priority indication information, the priority of the semi-static transmission is confirmed according to the higher or lower of the priority indication information carried by the first control information and the priority configured by RRC signaling.

[0096] Some exemplary embodiments are listed below to illustrate the Figure 1 or Figure 2 The data processing method provided. The following exemplary embodiments can be performed separately or in combination with each other, and the embodiments of the present application do not impose specific restrictions on this. The activation DCI or deactivation DCI in the following exemplary embodiments corresponds to the above-mentioned first control information.

[0097] In a first exemplary embodiment, if the deactivation of DCI simultaneously deactivates at least two semi-static transmissions, and the at least two semi-static transmissions are configured with the same priority by RRC signaling, the HARQ-ACK of the deactivated DCI is associated with the PDSCH of the semi-static transmission with the smallest index or the largest index among the at least two semi-static transmissions. That is, the position of the HARQ-ACK of the deactivated DCI in the semi-static HARQ-ACK codebook is the same as the reception position of the PDSCH of the semi-static transmission with the smallest index or the largest index among the at least two semi-static transmissions that are deactivated.

[0098] For example, deactivating DCI simultaneously deactivates 4 semi-static transmissions, and the indexes of the 4 semi-static transmissions are 1, 2, 3, and 4, respectively. They have corresponding PDSCHs of semi-static transmissions, and at this time, the position of the HARQ-ACK of the deactivated DCI in the semi-static HARQ-ACK codebook is the same as the receiving position of the PDSCH of the semi-static transmission with index 1 (the smallest index). In other words, the position of the HARQ-ACK of the deactivated DCI in the semi-static HARQ-ACK codebook is determined according to the receiving position of the PDSCH, that is, the position of the HARQ-ACK corresponding to the PDSCH reception location (PDSCH position) in the semi-static HARQ-ACK codebook is used as the position of the HARQ-ACK of the deactivated DCI in the semi-static codebook. This PDSCH position is not actually used to transmit downlink data, and its corresponding HARQ-ACK position is actually the HARQ-ACK of the deactivated DCI. Among the at least two deactivated semi-static transmissions, the PDSCH of the semi-static transmission that is not associated with the HARQ-ACK of the deactivated DCI may be used to schedule downlink data transmission.

[0099] In this way, when deactivating at least two semi-static transmissions, the deactivated DCI is only associated with the PDSCH receiving position of one semi-static transmission, so that the PDSCH of the unselected semi-static transmission can be used to schedule downlink data, thereby saving PDSCH resources.

[0100] In a second exemplary embodiment, on the basis of the first exemplary embodiment described above, when at least two deactivated semi-static transmissions are configured with different priorities by RRC signaling, the HARQ-ACK of the deactivated DCI is associated with the PDSCH of the semi-static transmission with the highest or lowest priority among the at least two semi-static transmissions, and if there are at least two semi-static transmissions with the highest or lowest priority, the PDSCH of the semi-static transmission with the smallest or largest index is further selected for association. That is, the position of the HARQ-ACK of the deactivated DCI in the semi-static HARQ-ACK codebook is the same as the receiving position of the PDSCH of the semi-static transmission with the highest or lowest priority among the at least two deactivated semi-static transmissions, and if there are still at least two semi-static transmissions with the highest or lowest priority, the receiving position of the PDSCH of the semi-static transmission with the smallest or largest index is further selected in the highest or lowest semi-static transmission.

[0101] It should be noted that if the receiving position of the PDSCH with the highest priority semi-static transmission is selected to be associated with the HARQ-ACK of the deactivated DCI, this can avoid the HARQ-ACK of the deactivated DCI from being discarded. For example, if the HARQ-ACK transmission of the deactivated DCI conflicts in the time domain with the transmission of information of other priorities, the high-priority HARQ-ACK can be ensured to be transmitted.

[0102] For example, deactivating DCI simultaneously deactivates 4 semi-static transmissions, and the indexes of the 4 semi-static transmissions are 1, 2, 3, and 4, respectively, and the priority of index 1 is high, the priority of index 2 is low, the priority of index 3 is high, and the priority of index 4 is low. They have corresponding PDSCHs of semi-static transmissions, respectively. At this time, the position of the HARQ-ACK of the deactivated DCI in the semi-static HARQ-ACK codebook is the same as the receiving position of the PDSCH of the highest priority semi-static transmission. At this time, index 1 and index 3 are selected, and then further, the same receiving position of the PDSCH of the semi-static transmission with the smallest index index 1 is selected. In other words, the position of the HARQ-ACK of the deactivated DCI in the semi-static HARQ-ACK codebook is determined according to the receiving position of the PDSCH, that is, the position of the HARQ-ACK corresponding to the PDSCH reception location (PDSCH position) in the semi-static HARQ-ACK codebook is used as the position of the HARQ-ACK of the deactivated DCI in the semi-static codebook. This PDSCH position is not actually used to transmit downlink data, and its corresponding HARQ-ACK position is actually the HARQ-ACK for deactivating DCI.

[0103] In this way, in addition to obtaining the benefits of the first exemplary embodiment, it is also possible to ensure that the HARQ-ACK for deactivating the DCI has a high priority, thereby avoiding being discarded when a transmission conflict occurs.

[0104] In the third exemplary embodiment, in both the first and second exemplary embodiments, the HARQ-ACK of the deactivated DCI is associated with the receiving position of the PDSCH of a semi-static transmission, and an agreed rule is used to determine a semi-static transmission. For the third exemplary embodiment, a flexible method is provided to determine a semi-static transmission. The details are as follows:

[0105] The base station indicates a semi-static transmission by carrying an indication information through a deactivation DCI. The position of the HARQ-ACK of the deactivation DCI in the semi-static HARQ-ACK codebook is associated with the PDSCH of the semi-static transmission indicated by the deactivation DCI. Here, a semi-static transmission is one of at least two semi-static transmissions deactivated by the deactivation DCI. Specifically, the base station indicates the PDSCH time domain resource allocation of a semi-static transmission by carrying an indication information through a deactivated DCI, which may specifically include one of the following methods: Method 1, using the time domain resource allocation field in the deactivated DCI to indicate a semi-static transmission from a deactivated semi-static transmission, and using the time domain resource allocation of the deactivated semi-static transmission; Method 2, using the time domain resource allocation field in the deactivated DCI to indicate a semi-static transmission from a deactivated semi-static transmission, and using the index of the deactivated semi-static transmission; Method 3, using the time domain resource allocation field in the deactivated DCI to indicate a semi-static transmission from a deactivated semi-static transmission, and using the sequential index value of the deactivated semi-static transmission, for example, after the indices of at least two semi-static transmissions to be deactivated are ascended or descended, a semi-static transmission is described according to the ascending or descending sequential index value (for example, after at least two semi-static transmissions are ascended in index order, it is described which semi-static transmission is selected).

[0106] In this way, the HARQ-ACK of a deactivated DCI can be dynamically associated with a PDSCH of a semi-static transmission to be suitable for the transmission of a dynamically scheduled PDSCH. For example, there are 4 deactivated semi-static transmissions, and the base station wants to use the PDSCH of the semi-static transmission with the smallest index for dynamically scheduled data transmission. However, according to the first and second exemplary embodiments, the PDSCH of the semi-static transmission with the smallest index is associated with the HARQ-ACK of the deactivated DCI, resulting in the base station being unable to use the PDSCH of the semi-static transmission with the smallest index to transmit dynamically scheduled data. However, in the third exemplary embodiment, the base station can dynamically indicate the association between the HARQ-ACK of the deactivated DCI and the PDSCH of another semi-static transmission, thereby ensuring that the base station uses the PDSCH of the semi-static transmission with the smallest index to transmit dynamically scheduled data. Among them, in the above-mentioned method 1, the PDSCH time domain resource allocation domain in the deactivated DCI is not used in the prior art, so it is recommended to reuse it; compared with method 1, methods 2 and 3 have the effect of reducing signaling overhead, because the total number of configured semi-static transmissions is less than or equal to the total number of time domain resource allocations; method 3 has smaller signaling overhead than method 2, because the number of deactivated semi-static transmissions is less than or equal to the number of configured semi-static transmissions.

[0107] In a fourth exemplary embodiment, the base station and the UE agree that when the RRC signaling configures at least two semi-static transmissions for the UE, the index value configured for the high-priority semi-static transmission is less than the index value configured for the low-priority semi-static transmission. In this way, it is equivalent to assigning a priority to the index when the RRC signaling configures the index of the semi-static transmission, and the priority of the index corresponds to the priority of the semi-static transmission. For example, 4 semi-static transmissions are configured for the UE, and 2 of them are high priority and 2 are low priority, then the indexes of the 2 high-priority semi-static transmissions are configured as 1 and 2 respectively, and the indexes of the 2 low-priority semi-static transmissions are configured as 3 and 4 respectively, or the indexes of the 2 low-priority semi-static transmissions can also be 5 and 6 respectively (as long as they are larger than the index values ​​of the 2 high-priority semi-static transmissions).

[0108] Alternatively, the base station and the UE agree that when at least two semi-static transmissions are configured for the UE, an index value configured for a high-priority semi-static transmission is greater than an index value configured for a low-priority semi-static transmission.

[0109] In this way, if at least two deactivated semi-static transmissions have different priorities configured by RRC signaling, when determining a semi-static transmission associated with the HARQ-ACK of the deactivated DCI, when executing according to the above-mentioned first exemplary embodiment, it can be ensured that the HARQ-ACK of the deactivated DCI has a high priority.

[0110] In a fifth exemplary embodiment, the base station and the UE agree that if the DCI is deactivated and at least two semi-static transmissions are deactivated at the same time, and the at least two semi-static transmissions are configured with different priorities by RRC signaling, the priority of the HARQ-ACK of the deactivated DCI is determined as at least one of the following:

[0111] The priority indicated by the priority indication information carried by the deactivation DCI (or activation DCI) can be used. In this way, a flexible HARQ-ACK priority can be provided for the deactivation DCI, regardless of whether the at least two semi-static transmissions to be deactivated are configured with priorities by RRC.

[0112] Alternatively, the priority of the semi-static transmission with the highest (or lowest) priority configured by RRC signaling among the at least two semi-static transmissions to be deactivated is used. This method does not matter whether the deactivation DCI carries priority indication information. This method can ensure that the deactivation DCI has a high priority to avoid being discarded when a transmission conflict occurs. If the at least two semi-static transmissions to be deactivated are not configured with priority by RRC signaling, they are processed according to low priority (high priority).

[0113] Alternatively, if the deactivation DCI carries priority indication information, and if at least two deactivated semi-static transmissions are not configured with priorities by RRC signaling, the priority indication information carried by the deactivation DCI shall prevail.

[0114] Alternatively, if the deactivation DCI carries priority indication information, and if at least two deactivated semi-static transmissions are configured with priorities by RRC signaling, the priority indication information carried by the deactivation DCI shall prevail.

[0115] Alternatively, if the deactivation DCI does not carry priority indication information, and if at least two deactivated semi-static transmissions are configured with priorities by RRC signaling, the priority of the semi-static transmission with the highest (or lowest) priority configured by RRC signaling among the at least two activated semi-static transmissions is used.

[0116] Alternatively, if the deactivation DCI does not carry priority indication information, and if at least two deactivated semi-static transmissions are not configured with priorities by RRC signaling, the low priority (or high priority) is used for determination.

[0117] Alternatively, if the deactivation DCI carries priority indication information, and if at least two deactivated semi-static transmissions are configured with priorities by RRC signaling, the higher (or lower) of the priority carried in the deactivation DCI and the priority configured by RRC for at least two semi-static transmissions shall prevail.

[0118] The above-mentioned determination rules can be used in combination. For example, when the deactivated DCI simultaneously deactivates at least two semi-static transmissions, if the deactivated DCI carries priority indication information (regardless of whether the RRC signaling configures priority for the at least two semi-static transmissions), the priority of the HARQ-ACK of the deactivated DCI is determined according to the priority carried by the deactivated DCI, otherwise, if the at least two deactivated semi-static transmissions are configured with priority by RRC signaling, the priority of the HARQ-ACK of the deactivated DCI is determined according to the high priority (or low priority) of the priorities configured by RRC signaling in the at least two deactivated semi-static transmissions, otherwise, the HARQ-ACK of the deactivated DCI is a low priority (or a high priority).

[0119] For another example, if at least two deactivated semi-static transmissions are configured with priorities by RRC signaling (regardless of whether the deactivation DCI carries priority indication information), the priority of the HARQ-ACK of the deactivated DCI is determined according to the high priority (or low priority) among the priorities configured by RRC signaling among the at least two deactivated semi-static transmissions; otherwise, the HARQ-ACK of the deactivated DCI is a low priority (or a high priority).

[0120] For another example, the priority of the HARQ-ACK of the deactivated DCI is determined according to the priority indication carried in the deactivation DCI and the higher priority of the at least two semi-static transmissions configured by RRC signaling to be deactivated (if they are all the same priority, the same priority shall prevail). Here, if the deactivation DCI does not carry a priority indication, the priority indication carried by the deactivation DCI is considered to be a low priority. If a semi-static transmission whose priority is not configured by RRC signaling is considered to be a low-priority semi-static transmission.

[0121] In addition, in the case where the deactivation DCI deactivates a semi-static transmission, the priority of the HARQ-ACK of the deactivation DCI is determined as at least one of the following:

[0122] Processing 1: For a semi-static transmission deactivation DCI HARQ-ACK priority (i.e., HARQ-ACK belongs to a high or low HARQ-ACK codebook), and the semi-static transmission is configured with priority by RRC, if the deactivation DCI does not carry priority indication information at the time of deactivation, the semi-static transmission is processed with the priority configured by RRC;

[0123] Processing 2: For a semi-static transmission deactivation DCI HARQ-ACK priority, and the semi-static transmission is not configured with priority by RRC, if the deactivation DCI does not carry priority indication information when deactivating, it is processed according to low priority (or high priority);

[0124] Processing 3: For a semi-static transmission deactivation DCI HARQ-ACK priority, and the semi-static transmission is configured with priority by RRC, if the deactivation DCI carries priority indication information at the time of deactivation, the priority indication carried in the deactivation DCI shall prevail;

[0125] Processing 4: For a semi-static transmission deactivation DCI HARQ-ACK priority, and the semi-static transmission is not configured with priority by RRC, if the deactivation DCI carries priority indication information at the time of deactivation, the priority indication carried in the deactivation DCI shall prevail;

[0126] Processing 5: For a semi-static transmission deactivation DCI HARQ-ACK priority, and the semi-static transmission is configured with priority by RRC, if the deactivation DCI carries priority indication information but is invalid during deactivation, the priority configured by RRC for the semi-static transmission shall prevail;

[0127] Processing 6: For a semi-static transmission deactivation DCI HARQ-ACK priority, and the semi-static transmission is not configured with priority by RRC, if the deactivation DCI carries priority indication information but is invalid when deactivating, it is processed according to low priority (or high priority);

[0128] Processing 7, for the HARQ-ACK priority of a semi-static transmission deactivation DCI, and the semi-static transmission is configured with priority by RRC, if the deactivation DCI carries priority indication information during deactivation, the higher (or lower) of the priority carried in the deactivation DCI and the priority configured by RRC shall prevail.

[0129] The above-mentioned treatments can be combined.

[0130] In a sixth exemplary embodiment, when the base station configures a priority of semi-static transmission, such as a high or low priority, through high-layer signaling RRC signaling, when the activation downlink control signaling (activation DCI, used to activate the DCI of semi-static transmission for the UE) carries a priority indication information (such as a high or low priority), the base station and the UE agree to use any of the following methods to process:

[0131] Method 1: If an activation DCI simultaneously activates the priorities of at least two semi-static transmissions, and the at least two activated semi-static transmissions are configured with different priorities by RRC signaling, the priority indication information carried by the activation DCI is valid (the priority configured by the RRC signaling of the at least two activated semi-static transmissions becomes invalid). For example, if the priority indication information is a high priority, then the at least two activated semi-static transmissions are determined to be of high priority according to the priority indication information carried by the activation DCI.

[0132] By adopting method 1, the problem that at least two semi-static transmission resources of the same priority are required for semi-static transmission can be effectively solved. For example, a base station or UE needs 4 semi-static transmissions of the same priority to be activated, but currently 4 semi-static transmissions are configured and configured with different priorities. At this time, method 1 can be used to activate the 4 semi-static transmissions at the same time, and the priority in the priority indication information carried by the activation DCI is applied to the 4 activated semi-static transmissions, thereby meeting the needs of the base station or UE. According to the existing mechanism, it is necessary to use RRC signaling to reconfigure the priorities of the 4 semi-static transmissions so that they have the same priority, and then use the activation DCI to activate the 4 semi-static transmissions one by one. Obviously, the existing mechanism is complicated compared to method 1.

[0133] Mode 2: If an activation DCI simultaneously activates the priorities of at least two semi-static transmissions, and the at least two activated semi-static transmissions are configured with different priorities by RRC signaling, the priority indication information carried by the activation DCI is invalid. For example, the at least two activated semi-static transmissions are configured with different priorities according to their respective RRC signaling.

[0134] In mode 2, when the base station or UE needs at least two semi-static transmissions to be activated, only one activation DCI can be used. According to the existing mechanism, the activation DCI needs to be sent one by one. Compared with the existing mechanism, mode 2 reduces the number of activation DCI transmissions.

[0135] Mode 3: If an activation DCI activates at least two semi-static transmissions, and there is a semi-static transmission whose priority is not configured by RRC signaling among the at least two activated semi-static transmissions, then the priority indication information carried by the activation DCI is applicable to the semi-static transmission that is activated and not configured with priority by RRC signaling, and the priority indication information carried by the activation DCI is not applicable to the semi-static transmission that is activated and configured with priority by RRC signaling.

[0136] In addition, in the case of activating a semi-static transmission by activating DCI, the priority of the semi-static transmission is determined as at least one of the following:

[0137] Processing a: For an activated semi-static transmission, which is configured with a priority by RRC, if the activation DCI does not carry priority indication information during activation, it is processed with the priority configured by RRC;

[0138] Processing b: for an activated semi-static transmission that is not configured with a priority by RRC, if the activation DCI does not carry priority indication information when activated, it is processed according to the low priority (or high priority);

[0139] Processing c: for an activated semi-static transmission, which is configured with a priority by RRC, if the activation DCI carries priority indication information at the time of activation, the priority indication carried in the activation DCI shall prevail;

[0140] Processing d: For an activated semi-static transmission that is not configured with a priority by RRC, if the activation DCI carries priority indication information at the time of activation, the priority indication carried in the activation DCI shall prevail;

[0141] Processing e, for an activated semi-static transmission, which is configured with priority by RRC, if the activation DCI carries priority indication information at the time of activation, the higher (or lower) priority carried in the activation DCI and the priority configured by RRC shall prevail.

[0142] The above processing methods can be used in combination.

[0143] By adopting method 3, the benefits of methods 1 and 2 can also be achieved.

[0144] Mode 4: If an activation DCI activates at least two semi-static transmissions at the same time, these semi-static transmissions must have the same priority configured by RRC signaling, and the priority indicated by the priority indication information carried by the activation DCI follows or modifies the priority of the activated semi-static transmission.

[0145] By adopting method 4, the benefits of methods 1, 2, and 3 can also be achieved.

[0146] In the seventh exemplary embodiment, if DCI is activated and at least two semi-static transmissions are activated at the same time, how to feedback the HARQ-ACK of the first PDSCH of each semi-static transmission may be:

[0147] The HARQ-ACK of the activated DCI performs feedback according to the relevant parameters in the activated DCI. For example, the uplink feedback position and PUCCH resources of the HARQ-ACK of the activated DCI are determined according to the PUCCH resource indication field and the PDSCH to HARQ-ACK feedback timing field in the activated DCI. The HARQ-ACK of the PDSCH of at least two activated semi-static transmissions, including the HARQ-ACK of the first PDSCH of each semi-static transmission, are sent according to the PUCCH resources configured for the semi-static transmission.

[0148] Alternatively, if activating DCI activates at least two semi-static transmissions at the same time, and these at least two semi-static transmissions may be configured with different priorities by RRC signaling, then the HARQ-ACK of the activated DCI is associated with the first PDSCH of a designated one of the at least two semi-static transmissions that are activated, and here, the method for determining the designated one semi-static transmission may adopt the method in the first and second exemplary embodiments. If the semi-static transmission is configured with an index according to the fourth exemplary embodiment, the first exemplary embodiment may be used to determine the designated one semi-static transmission. The first PDSCH of the remaining semi-static transmissions is sent according to the PUCCH resources configured for the semi-static transmission.

[0149] The various methods in the first to seventh exemplary embodiments described above can be used in combination without conflict. The various methods are also applicable to the priority of a semi-static transmission deactivated DCI and the priority of the HARQ-ACK for deactivating the DCI. In the various embodiments described above, the RRC signaling configures the priority for a semi-static transmission, and the RRC signaling provides a mapping relationship, the mapping relationship is the semi-static transmission corresponding to which HARQ-ACK codebook (that is, the HARQ-ACK of the semi-static transmission corresponds to the high-priority HARQ-ACK codebook, or the low-priority HARQ-ACK codebook). If the semi-static transmission corresponds to the high-priority HARQ-ACK codebook, the semi-static transmission is a high priority. If the semi-static transmission corresponds to the low-priority HARQ-ACK codebook, the semi-static transmission is a low priority. In the various methods in the first to seventh exemplary embodiments described above, determining the priority of the semi-static transmission is also determining the priority of the HARQ-ACK of the semi-static transmission. In the above example, the activation DCI or deactivation DCI does not carry a priority indication, including one of the following situations: RRC signaling does not configure the priority indication field for the activation DCI or deactivation DCI, the activation DCI or deactivation DCI carries a priority indication field but is agreed to be invalid, and the activation DCI or deactivation DCI does not contain a priority indication field (for example, when Fallback DCI (DCI 1-0 format or DCI 0-0 format) is used for activation or deactivation).

[0150] Figure 3 A flow chart of another data processing method provided by an embodiment is shown, Figure 3 As shown, the method provided in this embodiment is applicable to the first communication node, and the method includes the following steps.

[0151] S310. The first communication node configures and sends second control information to the second communication node.

[0152] Among them, the second control information includes: information used to indicate that the state of the secondary cell serving the second communication node has changed; the second control information also includes at least one of the following information: information used to indicate that the second control information is not used for scheduling user data, information determining the hybrid automatic repeat request-acknowledgement information HARQ-ACK resource of the second control information, information determining the interval timing from the time slot where the second control information is located to the time slot where the HARQ-ACK of the second control information is located, information determining the interval timing from the sub-time slot where the second control information is located to the sub-time slot where the HARQ-ACK of the second control information is located, information determining the position of the HARQ-ACK of the second control information in the dynamic HARQ-ACK codebook, priority information of the HARQ-ACK of the second control information, and determining the position of the HARQ-ACK of the second control information in the semi-static HARQ-ACK codebook.

[0153] In one embodiment, the second control information uses the downlink control information DCI format of the downlink scheduling data to set or reinterpret part of the bit fields in the DCI format, or uses the DCI format of the uplink scheduling data to set or reinterpret part of the bit fields in the DCI format.

[0154] In one embodiment, when the second control information is configured using the DCI format of the downlink scheduling data or reinterpreting a part of the bit fields in the DCI format, it includes at least one of the following definitions:

[0155] Reuse the physical uplink control channel PUCCH resource indication field in the DCI;

[0156] Reinterpret the physical downlink shared channel PDSCH to HARQ-ACK timing feedback field in the DCI as the interval timing from the time slot where the second control information is located to the time slot where the HARQ-ACK of the second control information is located;

[0157] Reinterpret the PDSCH to HARQ-ACK timing feedback field in the DCI as the interval timing from the sub-slot where the second control information is located to the sub-slot where the HARQ-ACK of the second control information is located;

[0160] The PDSCH frequency domain resource allocation field in the DCI is set to an agreed value, where the agreed value is used to represent the bit field in the DCI format of the downlink scheduling data as the second control information, and optionally, the agreed value may be 0;

[0161] A bit field in the DCI is reinterpreted as a field for determining the priority of HARQ-ACK of the second control information, and the bit field does not include a PUCCH resource indication field, a PDSCH to HARQ-ACK timing feedback field, a DAI field, a PDSCH time domain resource allocation field, and a PDSCH frequency domain resource allocation field.

[0162] In one embodiment, when the second control information is configured using the DCI format of the uplink scheduling data or reinterpreting a part of the bit fields in the DCI format, it includes at least one of the following definitions:

[0163] Reinterpret the first bit field in the DCI as a PUCCH resource indication field;

[0164] Reinterpreting the second bit field in the DCI as the interval timing from the time slot where the second control information is located to the time slot where the HARQ-ACK of the second control information is located;

[0165] Reinterpreting the second bit field in the DCI as the interval timing from the sub-time slot where the second control information is located to the sub-time slot where the HARQ-ACK of the second control information is located;

[0168] Reinterpret the PUSCH time-frequency resource allocation field in the DCI as a time-frequency resource field for allocating the HARQ-ACK of the second control information;

[0169] A bit field in the DCI is reinterpreted as a priority of HARQ-ACK for determining the second control information, wherein the bit field does not include a first bit field, a second bit field, a third bit field, a fourth bit field, and a PUSCH time-frequency resource allocation field.

[0170] In one embodiment, when the second control information is used to indicate that the states of at least two secondary cells serving the second communication node are changed, the HARQ-ACK of the second control information is counted in the HARQ-ACK of the serving cell that sends the second control information; or,

[0171] When the second control information is used to indicate that the states of at least two secondary cells serving the second communication node have changed, the HARQ-ACK of the second control information is counted in the HARQ-ACK of the serving cell with the smallest or largest index among the serving cells indicated by the second control information that have undergone state change; or,

[0172] When the second control information is used to indicate that the states of at least two secondary cells serving the second communication node change, the HARQ-ACK of the second control information is associated with a serving cell, wherein the serving cell is the serving cell indicated to be associated in the second control information.

[0173] In one embodiment, when the HARQ-ACK of the second control information is combined with the semi-static HARQ-ACK codebook, the first communication node determines a PDSCH from the associated service cell and uses the PDSCH reception position to determine the position of the HARQ-ACK of the second control information in the semi-static HARQ-ACK codebook.

[0174] Figure 4 A flow chart of another data processing method provided by an embodiment is shown. Figure 4 As shown, the method provided in this embodiment is applicable to the second communication node, and the method includes the following steps.

[0175] S410. The second communication node receives second control information sent by the first communication node.

[0176] Among them, the second control information includes: information used to indicate that the state of the secondary cell serving the second communication node has changed; the second control information also includes at least one of the following information: information used to indicate that the second control information is not used for scheduling user data, information determining the hybrid automatic repeat request-acknowledgement information HARQ-ACK resource of the second control information, information determining the interval timing from the time slot where the second control information is located to the time slot where the HARQ-ACK of the second control information is located, information determining the interval timing from the sub-time slot where the second control information is located to the sub-time slot where the HARQ-ACK of the second control information is located, information determining the position of the HARQ-ACK of the second control information in the dynamic HARQ-ACK codebook, priority information of the HARQ-ACK of the second control information, and determining the position of the HARQ-ACK of the second control information in the semi-static HARQ-ACK codebook.

[0177] In one embodiment, the second control information uses the downlink control information DCI format of the downlink scheduling data to set or reinterpret part of the bit fields in the DCI format, or uses the DCI format of the uplink scheduling data to set or reinterpret part of the bit fields in the DCI format.

[0178] In one embodiment, when the second control information is configured using the DCI format of the downlink scheduling data or reinterpreting a part of the bit fields in the DCI format, it includes at least one of the following definitions:

[0179] Reuse the physical uplink control channel PUCCH resource indication field in the DCI;

[0184] The PDSCH frequency domain resource allocation field in the DCI is set to an agreed value, where the agreed value is used to represent the bit field in the DCI format of the downlink scheduling data as the second control information, and optionally, the agreed value may be 0;

[0185] A bit field in the DCI is reinterpreted as a field for determining the priority of HARQ-ACK of the second control information, and the bit field does not include a PUCCH resource indication field, a PDSCH to HARQ-ACK timing feedback field, a DAI field, a PDSCH time domain resource allocation field, and a PDSCH frequency domain resource allocation field.

[0191] Reinterpret the fourth bit field in the DCI as a PDSCH time domain resource allocation field, used to determine the position of the HARQ-ACK of the second control information in the semi-static HARQ-ACK codebook;

[0192] Reinterpret the PUSCH time-frequency resource allocation field in the DCI as a time-frequency resource field for allocating the HARQ-ACK of the second control information;

[0193] A bit field in the DCI is reinterpreted as a priority of HARQ-ACK for determining the second control information, wherein the bit field does not include a first bit field, a second bit field, a third bit field, a fourth bit field, and a PUSCH time-frequency resource allocation field.

[0194] In one embodiment, when the second control information is used to indicate that the states of at least two secondary cells serving the second communication node are changed, the HARQ-ACK of the second control information is counted in the HARQ-ACK of the serving cell that sends the second control information; or,

[0195] When the second control information is used to indicate that the states of at least two secondary cells serving the second communication node have changed, the HARQ-ACK of the second control information is counted in the HARQ-ACK of the serving cell with the smallest or largest index among the serving cells indicated by the second control information that have undergone state change; or,

[0196] When the second control information is used to indicate that the states of at least two secondary cells serving the second communication node change, the HARQ-ACK of the second control information is associated with a serving cell, wherein the serving cell is the serving cell indicated to be associated in the second control information.

[0197] In one embodiment, when the HARQ-ACK of the second control information is combined with the semi-static HARQ-ACK codebook, a PDSCH reception position determined in the associated serving cell is used to determine the position of the HARQ-ACK of the second control information in the semi-static HARQ-ACK codebook.

[0198] Some exemplary embodiments are listed below to illustrate the Figure 3 or Figure 4 The data processing method provided in the following exemplary embodiments can be performed separately or in combination with each other, and the embodiments of the present application do not impose specific limitations on this.

[0199] In the discussion of NR, it is currently considered to introduce a dormant secondary cell Scell. The base station notifies the UE whether a normal Scell ​​is converted into a dormant Scell, or whether a dormant Scell ​​is converted into a normal Scell. This is mainly for energy saving.

[0200] The method of notifying the UE by the base station includes using physical layer signaling, such as carrying a specially designed DCI in the PDCCH to notify the UE, and this special DCI (corresponding to the second control information mentioned above) does not schedule data. If this mechanism is used to notify the UE, in order to ensure reliability, it is necessary to consider designing a corresponding HARQ-ACK feedback for this notification signaling, that is, designing a corresponding HARQ-ACK feedback for the DCI signaling used to notify the UE of the Scell ​​switch, and this DCI does not schedule data.

[0201] If the above-mentioned special DCI is obtained by improving the existing DCI of downlink scheduling data, and considering that the special DCI needs to support HARQ-ACK feedback, consider using the following method to improve the existing DCI of downlink scheduling data.

[0202] In the eighth exemplary embodiment, considering that this special DCI does not schedule downlink data, it is recommended that the special DCI has a PUCCH resource indication field and a PDSCH to HARQ-ACK timing feedback field, and these two fields are used to determine the position and PUCCH resource of the HARQ-ACK feedback of the special DCI. Here, the PDSCH to HARQ-ACK timing feedback field and the PUCCH resource indication field can also be agreed upon in advance, which can reduce the overhead of the special DCI.

[0203] In this way, the HARQ-ACK of the special DCI can be guaranteed to be sent independently. However, since the HARQ-ACK of the special DCI may also be transmitted in combination with the semi-static HARQ-ACK codebook or the dynamic HARQ-ACK codebook, the following method can be further considered for this situation.

[0204] In a ninth exemplary embodiment, based on the eighth exemplary embodiment, the special DCI is further provided with a downlink authorization index (DAI) field. This DAI field is used to determine the position of the HARQ-ACK of the special DCI in the dynamic HARQ-ACK codebook. This method can solve the position of the HARQ-ACK of the special DAI in the dynamic HARQ-ACK codebook when the HARQ-ACK of the special DCI is transmitted in combination with the dynamic HARQ-ACK codebook.

[0205] In the tenth exemplary embodiment, based on the eighth exemplary embodiment, the special DCI carries a PDSCH resource allocation information, and the PDSCH is not used to transmit data, that is, the PDSCH resource position is used to determine the position of the HARQ-ACK of the special DCI in the semi-static HARQ-ACK codebook. In order to reduce overhead, the PDSCH resource allocation information here may only be the PDSCH time domain resource allocation, excluding the PDSCH frequency domain resource allocation.

[0206] Further, the HARQ-ACK of the special DCI is associated with the service cell (here the service cell can also be described as a carrier) that sends the special DCI, that is, when there are multiple carriers, the HARQ-ACK of the special DCI is counted in the HARQ-ACK of the carrier that sends the special DCI. Further, it can also be that the HARQ-ACK of the special DCI is associated with the secondary cell (Scell) that needs to change state indicated by the special DCI. If the special DCI indicates at least two Scell ​​conversion states at the same time, the Scell ​​with the smallest or largest index is selected for association (or a service cell is indicated in the special DCI, and the HARQ-ACK of the special DCI is associated with the indicated service cell). That is, when there are multiple carriers, the special DCI is sent in the service cell 1, but is used to instruct Scell2 and Scell3 to perform a state transition. At this time, the HARQ-ACK of the special DCI is associated with Scell2 (assuming the index is the smallest).

[0207] After the HARQ-ACK of the special DCI is associated with a serving cell, it is only determined that the HARQ-ACK of the special DCI is counted in the HARQ-ACK of that carrier, and it is necessary to further determine a PDSCH reception position from the serving cell to determine the position of the HARQ-ACK of the special DCI in the semi-static HARQ-ACK codebook.

[0208] In this way, the combination of HARQ-ACK of special DCI and semi-static HARQ-ACK codebook can be solved, and the position of HARQ-ACK of special DCI in the semi-static HARQ-ACK codebook can be solved.

[0209] If the above-mentioned special DCI is obtained by improving the existing DCI of uplink scheduling data, and considering that the special DCI needs to support HARQ-ACK feedback, consider using the following method to improve the existing DCI of uplink scheduling data.

[0210] In the eleventh exemplary embodiment, a PUCCH resource indication field is added to the special DCI, and a PDSCH to HARQ-ACK timing feedback field is added. These two fields are used to determine the location and PUCCH resources of the HARQ-ACK feedback of the special DCI. Here, the PDSCH to HARQ-ACK timing feedback field and the PUCCH resource indication field can also be used in a pre-agreed manner to reduce the overhead of the special DCI. The above two fields can also be implemented by reinterpreting other parameters in the existing DCI for scheduling uplink data, because the DCI for scheduling uplink data no longer schedules uplink data, and there are a large number of other fields that can be used for reinterpretation.

[0211] In this way, the HARQ-ACK of the special DCI can be guaranteed to be sent independently. However, since the HARQ-ACK of the special DCI may also be transmitted in combination with the semi-static HARQ-ACK codebook or the dynamic HARQ-ACK codebook, the following method can be further considered for this situation.

[0212] In the twelfth exemplary embodiment, on the basis of the eleventh exemplary embodiment, the special DCI further adds a count downlink grant index (Counter-DAI) field. This count downlink grant index field is used to determine the position of the HARQ-ACK of the special DCI in the dynamic HARQ-ACK codebook. This method can solve the position of the HARQ-ACK of the special DAI in the dynamic HARQ-ACK codebook when the HARQ-ACK of the special DCI is transmitted in combination with the dynamic HARQ-ACK codebook.

[0213] In the thirteenth exemplary embodiment, on the basis of the eleventh exemplary embodiment, the special DCI adds another PDSCH resource allocation information, and the PDSCH is not used to transmit data, that is, the PDSCH resource position is used to determine the position of the HARQ-ACK of the special DCI in the semi-static HARQ-ACK codebook. In order to reduce overhead, the PDSCH resource allocation information here may only be the PDSCH time domain resource allocation, excluding the PDSCH frequency domain resource allocation.

[0214] In the fourteenth exemplary embodiment, the HARQ-ACK of the special DCI is associated with the service cell (here the service cell may also be described as a carrier) that sends the special DCI, that is, when there are multiple carriers, the HARQ-ACK of the special DCI is counted in the HARQ-ACK of the carrier that sends the special DCI. Further, it may also be that the HARQ-ACK of the special DCI is associated with the secondary cell (Scell) that needs to change state as indicated by the special DCI. If the special DCI indicates at least two Scell ​​conversion states at the same time, the Scell ​​with the smallest or largest index is selected for association (or a service cell is indicated in the special DCI, and the HARQ-ACK of the special DCI is associated with the indicated service cell). That is, when there are multiple carriers, the special DCI is sent in the service cell 1, but is used to instruct Scell2 and Scell3 to perform a state transition. At this time, the HARQ-ACK of the special DCI is associated with Scell2 (assuming the smallest index).

[0215] After the HARQ-ACK of the special DCI is associated with a serving cell, it is only determined that the HARQ-ACK of the special DCI is counted in the HARQ-ACK of that carrier, and it is necessary to further determine a PDSCH reception position from the serving cell to determine the position of the HARQ-ACK of the special DCI in the semi-static HARQ-ACK codebook.

[0216] In this way, the combination of HARQ-ACK of special DCI and semi-static HARQ-ACK codebook can be solved, and the position of HARQ-ACK of special DCI in the semi-static HARQ-ACK codebook can be solved.

[0217] In the fifteenth exemplary embodiment, the special DCI carries a PUSCH resource allocation, and the HARQ-ACK of the special DCI is transmitted in the PUSCH resource. That is, the base station sends a special DCI to the UE and carries a PUSCH resource allocation, and the UE transmits the HARQ-ACK of the special DCI in the PUSCH resource. The HARQ-ACK of the special DCI here can be in the form of a MAC layer control unit.

[0218] On the basis of the eighth to fifteenth exemplary embodiments described above, in order to further solve the problem of how the HARQ-ACK of the special DCI should determine the priority, a priority indication field may be added to the special DCI, and the priority indication field is used to indicate the priority corresponding to the HARQ-ACK of the special DCI. Alternatively, a bit field other than the bit field described in the above methods 10 to 17 in the existing DCI is reinterpreted as a priority bit field describing the HARQ-ACK of the special DCI.

[0219] In this way, when the HARQ-ACK of the special DCI is combined with the semi-static HARQ-ACK codebook (or dynamic HARQ-ACK codebook), it can be combined into codebooks of different priorities according to the priority. Further, it is recommended that the base station and the UE agree that the HARQ-ACK of the special DCI always has a high priority to avoid being discarded when a transmission conflict occurs.

[0220] In 5G technology, in order to ensure coverage and transmit low-latency and high-reliability services in a short transmission time, the Transport Block Repetition for Uplink Transmission with a Configured Grant technology based on scheduling-free repetition is introduced. Among them, the Release 15 standard stipulates that the repetition of the transport block (TB) is based on slot repetition, that is, the TB is repeatedly sent using multiple time slots, and the TB is only sent once in each time slot, and the TB has the same time domain resource allocation in each time slot.

[0221] In order to further optimize the service performance of ultra-high reliability and ultra-low latency transmission, the Release 16 standard needs to enhance the scheduling-free repeated transmission, that is, to introduce one or more repeated transmissions of the same TB in the same time slot, or to repeat the transmission of the same TB across time slot boundaries in multiple consecutively available time slots.

[0222] For the unscheduled transmission types Type 1 (Type 1 PUSCH transmissions with a configured grant) and Type 2 (Type 2 PUSCH transmissions with a configured grant), the time domain resource allocation table (TDRA) of Release 15 has been clearly defined, but there is no solution for how to define the time domain resource allocation table of Release 16.

[0223] Among them, the scheduling-free transmission type Type1 is to configure the scheduling information by RRC; the scheduling-free transmission type Type2 is to configure the scheduling information by activating DCI.

[0224] Specifically, the time domain allocation table of Release 16 is determined according to the following method:

[0225] Method 1: A TDRA table is configured for the scheduling-free transmission type Type 1 through RRC signaling, and the TDRA table is different from the table used by the scheduling-free transmission type Type 2.

[0226] In one embodiment, the TDRA table used by the scheduling-free transmission type Type 1 does not include an indication of the number of repetitions, and the table used by the scheduling-free transmission type Type 2 includes an indication of the number of repetitions.

[0227] In one embodiment, the TDRA table used by the scheduling-free transmission type Type1 independently indicates the start symbol S of the time domain resource and the number of time domain duration symbols L of the time domain resource for data, and S+L may be an integer greater than 14.

[0228] In one embodiment, the scheduling-free transmission type Type 2 adopts a dynamically scheduled TDRA table.

[0229] Specifically, as shown in Table 1, K2 refers to the time domain offset (slot offset), which is the time length between the terminal receiving the DCI and sending the PUSCH. S refers to the starting symbol of the time domain resource of the PUSCH, L is the number of time domain continuous length symbols of the time domain resource of the PUSCH, and S+L can be an integer greater than 14.

[0230] Table 1 A TDRA information table

[0231]

[0232] When the network side indicates to use the PUSCH transmission type of Release 16, the terminal uses the newly defined TDRA table to determine the time domain allocation resources.

[0233] In one embodiment, the newly defined table may be as shown in Table 2, which adds a column Number of repetition on the basis of Table 1, and the column indicates the number of repetitions.

[0234] Table 2 Another TDRA information table

[0235]

[0236] Method 2: For the PUSCH of Release 16, there are multiple TDRA tables. For example, there are different TDRA tables according to different DCI formats; for example, the table configured for DCI format 0_1 ​​is TDRAforDCIformat 0_1 ​​and the table configured for DCIformat 0_2 is TDRAforDCIformat 0_2.

[0237] In addition, there are TDRA forms that have been approved for Release 15, which are referred to as legacy TDRA forms.

[0238] Then, for the terminal, how to determine the time domain allocation information adopted by Release 16 based on these three tables, at least one of the following methods is used to determine:

[0239] A. Determined according to predefined rules. Specifically: when the network indicates that the PUSCH transmission type of Release 15 is used, the terminal uses the legacy TDRA table. When the network indicates that the PUSCH transmission type of Release 16 is used, the terminal uses the table TDRAforDCIformat 0_2, or, when the network indicates that the PUSCH transmission type of Release 16 is used, the terminal uses the table TDRAforDCIformat 0_1.

[0240] B. According to RRC signaling instructions. Specifically: When the network side indicates to use the PUSCH transmission type of Release 15, the terminal uses the legacy TDRA table. When the network side indicates to use the PUSCH transmission type of Release 16, the terminal selects to use the table TDRAforDCIformat 0_1 ​​or the table TDRAforDCIformat 0_2 according to the RRC signaling.

[0241] Specifically, the RRC signaling content is table TDRAforDCIformat 0_1. If the RRC signaling is not configured, table TDRAforDCIformat 0_2 is used by default.

[0242] Alternatively, the RRC signaling content is table TDRAforDCIformat 0_2. If the RRC signaling is not configured, table TDRAforDCIformat 0_1 ​​is used by default.

[0243] Alternatively, the RRC signaling indicates two logic values. When the indication is a first logic value, the terminal uses the TDRA table corresponding to TDRAforDCIformat 0_2; when the indication is a second logic value, the terminal uses the TDRA table corresponding to TDRAforDCIformat 0_1.

[0244] C. According to RRC signaling instructions.

[0245] Specifically: RRC signaling is used to indicate three logic values. When the indication is the third logic value, the terminal uses the table legacyTDRA; when the indication is the fourth logic value, the terminal uses the table TDRAforDCIformat 0_2; when the indication is the fifth logic value, the terminal uses the table TDRAforDCIformat 0_1.

[0246] D. Instructed by RRC signaling

[0247] Specifically, the first RRC signaling content is the table legacy TDRA, and the second RRC signaling indicates two logical values. If the first RRC signaling is not configured, and the second RRC signaling indicates the sixth logical value, the terminal uses the table TDRAforDCIformat 0_2. Or if the first RRC signaling is not configured, and the second RRC signaling indicates the seventh logical value, the terminal uses the table TDRAforDCIformat 0_1.

[0248] Or, specifically: the third RRC signaling content is table TDRAforDCIformat 0_1, and the fourth RRC signaling indicates two logical values. If the third RRC signaling is not configured, and the fourth RRC signaling indicates the eighth logical value, the terminal uses table TDRAforDCIformat 0_2. Or if the third RRC signaling is not configured, and the fourth RRC signaling indicates the ninth logical value, the terminal uses table legacy TDRA.

[0249] Or, specifically: the fifth RRC signaling content is the table TDRAforDCIformat 0_2, and the sixth RRC signaling indicates two logical values. If the fifth RRC signaling is not configured, and the sixth RRC signaling indicates the tenth logical value, the terminal uses the table TDRAforDCIformat 0_1. Or if the fifth RRC signaling is not configured, and the sixth RRC signaling indicates the eleventh logical value, the terminal uses the table legacy TDRA.

[0250] Among them, the table TDRAforDCIformat0_2 and the table TDRAforDCIformat0_1 mentioned in A, B, C and D may include a column indicating the number of repetitions, or these two tables may not include a column indicating the number of repetitions.

[0251] This embodiment only uses the uplink PUSCH as an example to explain the inventive method. In fact, the repeated transmission information can also be carried on physical layer channels such as PDSCH and PDCCH.

[0252] Figure 5A schematic diagram of the structure of a data processing device provided by an embodiment is shown. The data processing device can be configured in a first communication node, such as Figure 5 As shown, it includes: a sending module 10.

The implementation principle and technical effect of the data processing device provided in this embodiment are similar to those of the above embodiment and will not be repeated here.

[0255] In one embodiment, when the first control information is used to deactivate at least two semi-static transmissions and the at least two semi-static transmissions have the same priority, the position of the hybrid automatic repeat request-acknowledgement information HARQ-ACK of the first control information in the semi-static HARQ-ACK codebook is associated with the physical downlink shared channel PDSCH of the first semi-static transmission; wherein,

[0258] The first semi-static transmission is indicated by an indication information carried by the first control information, wherein the indication information is the PDSCH time domain resource allocation information corresponding to at least two deactivated semi-static transmissions, or is the sequential index value of the index values ​​of at least two deactivated semi-static transmissions in ascending or descending order.

[0259] In one embodiment, when the first control information is used to deactivate at least two semi-static transmissions, and the at least two semi-static transmissions have different priorities, the position of the HARQ-ACK of the first control information in the semi-static HARQ-ACK codebook is associated with the PDSCH of the first semi-static transmission; wherein,

[0260] The first semi-static transmission is the semi-static transmission with the highest priority among all deactivated semi-static transmissions; or,

[0261] The first semi-static transmission is the semi-static transmission with the lowest priority among all deactivated semi-static transmissions; or,

[0262] The first semi-static transmission is the semi-static transmission with the highest priority among all deactivated semi-static transmissions, and the index of the first semi-static transmission is the smallest among the indexes of all deactivated semi-static transmissions with the highest priority; or,

[0264] The first semi-static transmission is the semi-static transmission with the lowest priority among all deactivated semi-static transmissions, and the index of the first semi-static transmission is the smallest among the indexes of all deactivated semi-static transmissions with the highest priority; or,

[0265] The first semi-static transmission is the semi-static transmission with the lowest priority among all deactivated semi-static transmissions, and the index of the first semi-static transmission is the largest among the indexes of all deactivated semi-static transmissions with the highest priority.

[0266] In one embodiment, when at least two semi-static transmissions have different priorities, the first communication node configures an index value of a high-priority semi-static transmission that is smaller than an index value of a low-priority semi-static transmission, or the first communication node configures an index value of a high-priority semi-static transmission that is larger than an index value of a low-priority semi-static transmission.

[0267] In one embodiment, when the first control information is used to deactivate at least two semi-static transmissions, the priority of the HARQ-ACK of the first control information is confirmed in one of the following ways:

[0268] Confirmation according to the priority indication information carried by the first control information; or,

[0269] Confirmation based on the priority of the semi-static transmission with the highest priority configured by the radio resource control RRC signaling among the at least two semi-static transmissions that are deactivated; or,

[0270] Confirming the priority of the higher one of the priority indication information carried by the first control information and the priority of the at least two deactivated semi-static transmissions configured by RRC signaling, wherein if the first control information does not carry the priority indication information, the priority indication information carried by the first control information is considered to be a low priority; or,

[0271] If the first control information carries priority indication information, confirm according to the priority indication information carried by the first control information; otherwise, if the at least two deactivated semi-static transmissions are configured with priorities by RRC signaling, confirm according to the higher priority among the priorities configured by RRC signaling in the at least two deactivated semi-static transmissions; otherwise, the HARQ-ACK of the first control information is confirmed as a low priority; or,

[0272] If the at least two deactivated semi-static transmissions are configured with priorities by RRC signaling, confirmation is performed according to a higher priority among the priorities configured by RRC signaling in the at least two deactivated semi-static transmissions; otherwise, the HARQ-ACK of the first control information is confirmed as a low priority;

[0273] If a semi-static transmission is not configured with a priority by RRC signaling, it is confirmed that the semi-static transmission is configured with a low priority by RRC signaling.

[0274] In one embodiment, when the first control information is used to activate at least two semi-static transmissions and the at least two semi-static transmissions have different priorities, the priority indication information carried by the first control information is valid and applicable to the at least two semi-static transmissions; or,

[0275] When the first control information is used to activate at least two semi-static transmissions, and the at least two semi-static transmissions have different priorities, the priority indication information carried by the first control information is invalid and is not applicable to the at least two semi-static transmissions; or,

[0276] When the first control information is used to activate at least two semi-static transmissions, and there is a semi-static transmission whose priority is not configured by RRC signaling among the at least two semi-static transmissions, the priority of the semi-static transmission whose priority is not configured by RRC signaling is confirmed according to the priority indication information carried by the first control information; or,

[0277] When the first control information is used to activate at least two semi-static transmissions, the at least two semi-static transmissions are required to have the same RRC signaling configured priority. The priority indicated by the priority indication information carried by the first control information allows following or modifying the RRC signaling configured priority of at least two semi-static transmissions.

[0278] In one embodiment, when the first control information is used to activate a semi-static transmission and a priority of the semi-static transmission is configured by RRC signaling, if the first control information does not carry priority indication information, the priority of the semi-static transmission is confirmed according to the priority configured by RRC signaling; or,

[0281] When the first control information is used to activate a semi-static transmission and the priority of the semi-static transmission is not configured by RRC signaling, if the first control information carries priority indication information, the priority of the semi-static transmission is confirmed according to the priority indication information carried by the first control information; or,

[0282] When the first control information is used to activate a semi-static transmission and a semi-static transmission is configured with a priority by RRC signaling, if the first control information carries priority indication information, the priority of the semi-static transmission is confirmed according to the higher or lower of the priority indication information carried by the first control information and the priority configured by RRC signaling.

[0283] In one embodiment, when the first control information is used to deactivate a semi-static transmission, and the semi-static transmission is configured with a priority by RRC signaling, if the first control information does not carry priority indication information, the priority of the semi-static transmission is confirmed according to the priority configured by RRC signaling; or,

The implementation principle and technical effect of the data processing device provided in this embodiment are similar to those of the above embodiment and will not be repeated here.

[0291] In one embodiment, when the first control information is used to deactivate at least two semi-static transmissions and the at least two semi-static transmissions have the same priority, the position of the hybrid automatic repeat request-acknowledgement information HARQ-ACK of the first control information in the semi-static HARQ-ACK codebook is associated with the physical downlink shared channel PDSCH of the first semi-static transmission; wherein,
