[0004] With the development of communication technology, the research on the fifth generation mobile communication technology (5G) has also been launched. The wireless access of 5G is called New Radio, or NR for short. Since 5G needs to support ultra-high data transmission rates, a large number of data connections, and low data transmission delay, compared with the currently used Long Term Evolution (LTE) system; in order to improve the flexibility of resource allocation and reduce data transmission delay, the 5G NR system can not only implement resource allocation in units of time slots like the LTE system, but also implement resource allocation in units of symbols within time slots, which can be called symbol-level resource allocation.

[0005] In the 5G NR system, the 5G base station gNB can perform symbol-level scheduling of the time domain resources of the transmission channel, and can also configure the time domain resources at the symbol level in a dynamic or semi-static manner. Therefore, when the scheduling information of the gNB for the time domain resources conflicts with the configuration information for the time domain resources, the terminal will be unable to transmit the channel for a short period of time.

[0055] In order to enable a more detailed understanding of the features and technical contents of the embodiments of the present invention, the implementation of the embodiments of the present invention is described in detail below in conjunction with the accompanying drawings. The attached drawings are for reference only and are not intended to limit the embodiments of the present invention.

[0056] See also Figure 1 , which shows an atypical application scenario of an embodiment of the present invention, in which a network device and a terminal device may be included. The network device may be an evolved node (eNB) in an LTE system, or a base station gNB in ​​a 5G NR system, or other network devices, as long as the terminal device can be provided with a function of accessing a mobile communication network. The terminal device may include a cellular phone, a smart phone, a session initiation protocol (SIP) phone, a laptop computer, a personal digital assistant (PDA), a satellite radio, a global positioning system, a multimedia device, a video device, a digital audio player (e.g., an MP3 player), a camera, a game console, a tablet computer, or any other device with similar functions. At the same time, the terminal device may also be referred to as a user device, a terminal, a mobile station, a subscriber station, a mobile unit, a subscriber unit, a wireless unit, a remote unit, a mobile device, a wireless device, a wireless communication device, a remote device, a mobile subscriber station, an access terminal, a mobile terminal, a wireless terminal, a remote terminal, a handset, a user agent, a mobile client, a client, or some other appropriate terminology by those skilled in the art.

[0057] Combination Figure 1In the application scenario shown, when multi-slot or slot aggregation scheduling is performed, the base station can configure the start symbol and the end symbol for the transmission channel in each slot of the multiple slots, thereby realizing symbol-level configuration. In addition, the base station can also perform symbol-level scheduling for the slot used for the transmission channel. In an embodiment of the present invention, the channel to be transmitted may include data channels such as a physical downlink shared channel (PDSCH, Physical Downlink Shared CHannel) and a physical uplink shared channel (PUSCH, Physical Uplink Shared CHannel), and may also include: control channels such as a physical downlink control channel (PDCCH, Physical Downlink Control CHannel) and a physical uplink control channel (PUCCH, Physical Uplink Control CHannel). In order to clearly illustrate the technical solution of the embodiment of the present invention, the embodiment of the present invention preferably uses a downlink data channel, such as PDSCH as an example for explanation. It can be understood that those skilled in the art can apply the technical solution of the embodiment of the present invention to other types of channels under the guidance of the downlink data channel.

[0058] When time domain resources, such as symbol-level scheduling and symbol-level configuration of time slots, conflict occurs, the terminal will be unable to perform channel transmission for a short period of time. The specific conflict situations may include at least the following two examples:

[0059] Example 1

[0060] like Figure 2 As shown, taking the channel to be transmitted as a downlink data channel, such as PDSCH, the base station gNB schedules part of the symbol resources in each of the four time slots to transmit the downlink data channel, namely time slot 0, time slot 1, time slot 2 and time slot 3. The length of each time slot is 14 symbols, but when scheduling the above four time slots to transmit PDSCH, it is not necessary to occupy all the symbols in the time slot. On the other hand, when the base station performs symbol-level configuration of time domain resources for the terminal, all symbols of time slot 2 are configured for uplink channel transmission, such as Figure 2 In this case, the scheduling resources of time slot 2 as a whole will conflict with the configuration resources for time slot 2, as shown in the middle point filling block. Figure 2 The conflict area is shown by the cross-hatching fill.

[0061] Example 2

[0062] like Figure 3As shown, taking the channel to be transmitted as an example, such as PDSCH, the base station gNB schedules part of the symbol resources in each of the four time slots for transmission, namely time slot 0, time slot 1, time slot 2 and time slot 3. The length of each time slot is 14 symbols, but when scheduling the above four time slots to transmit PDSCH, it is not necessary to occupy all the symbols in the time slot. On the other hand, when the base station configures the symbols of the time domain resources for the terminal, it configures part of the symbols of time slot 2 for the transmission of the uplink channel, such as Figure 3 At this time, some symbols of the scheduled resources of time slot 2 will conflict with the configured resources of time slot 2, as shown in the middle point filling block. Figure 3 The conflict area is shown by the cross-hatching fill.

[0063] The specific conflict situation is not limited to the above two examples. It should be pointed out that when the base station faces the conflict described above, in order to resolve the conflict, the time domain resources to be scheduled will be adjusted during the time domain resource scheduling to avoid the conflict. However, after the base station adjusts the time domain resources to be scheduled, it is necessary to notify the terminal of the adjusted time domain resource scheduling status during transmission, which will cause a lot of signaling overhead, and when the base station needs to notify the terminal of the adjustment of the time domain resource scheduling through control signaling multiple times, the terminal will also increase the probability of false detection of the control signaling. The technical solution of the embodiment of the present invention can reduce the signaling overhead when notifying the terminal after the base station adjusts the time domain resources to be scheduled, and improve the detection reliability of the control signaling.

[0064] Embodiment 1

[0065] See also Figure 4 , which shows a method for determining time domain resources provided by an embodiment of the present invention, which can be applied to a terminal, and the method may include:

[0066] S401: receiving allocation information of time domain resources to be scheduled sent by a network device;

[0067] The time domain resources to be scheduled include time domain resources that require channel transmission;

[0068] S402: Based on a set determination rule, determine a corresponding time domain position for the time domain resource to be scheduled according to the uplink and downlink time domain resource configuration information and allocation information;

[0069] S403: Perform channel transmission using the time domain resources to be scheduled according to the time domain positions corresponding to the time domain resources to be scheduled.

[0070] It needs to be explained that the channels may include data channels such as physical downlink shared channel (PDSCH) and physical uplink shared channel (PUSCH), and may also include control channels such as physical downlink control channel (PDCCH) and physical uplink control channel (PUCCH).

[0071] It can be understood that the set determination rule can be a determination rule agreed upon in advance by the terminal and the network equipment, such as the base station gNB. The base station gNB can adjust the scheduling of time domain resources to avoid conflicts after the scheduling of time domain resources conflicts with the configuration of time domain resources, and the specific adjustment method or means of the base station gNB can be described by the determination rule. Therefore, when the terminal learns the set determination rule, it can make the same adjustment as the base station gNB, so that the base station gNB does not need to notify the terminal after adjusting the scheduling of time domain resources, thereby reducing the signaling overhead between the terminal and the base station gNB.

[0072] for Figure 4 In the technical solution shown, in a possible implementation, the allocation information of the time domain resources to be scheduled can be carried in the downlink control information (DCI). It can be understood that DCI can be dynamically configured, so that the base station gNB can send the allocation information to the terminal in time, so that the terminal can determine the location of the time domain resources to be scheduled in time to avoid conflicts.

[0073] for Figure 4 The technical solution shown, in a possible implementation, may also include: receiving uplink and downlink time domain resource configuration information sent by the network device; wherein the uplink and downlink time domain resource configuration information includes time slot level position information and / or symbol level position information of available time domain resources. It should be explained that when used to characterize the position of the time domain resource in time slots, it is called the time slot level position information of the time domain resource; when used to characterize the position information of the time domain resource in symbols, it is called the symbol level position information of the time domain resource.

[0074] Specifically, the uplink and downlink time domain resource configuration information may be predefined information, or may be carried in radio resource control (RRC) signaling and / or DCI. In specific implementation, it may be frame structure information and / or a slot format indicator (SFI).

[0075] for Figure 4 In the technical scheme shown, the allocation information of the time domain resources to be scheduled is not the scheduling information after the base station gNB adjusts the time domain resources to be scheduled, but the description information of the time domain resources to be scheduled. After the terminal obtains the description information of the time domain resources to be scheduled, it determines the time domain position corresponding to the time domain resources to be scheduled according to the determination rule obtained and agreed with the base station gNB, so that the time domain position corresponding to the time domain resources to be scheduled finally determined by the terminal is consistent with the scheduling information adjusted by the base station gNB for the time domain resources to be scheduled. Therefore, there is no need for the base station to notify the terminal of the adjusted scheduling information for the time domain resources to be scheduled during the channel transmission process, which saves the signaling overhead between the base station gNB and the terminal during the channel transmission process, and also avoids the increase in the probability of false detection caused by repeated sending of control signaling.

[0076] Therefore, in this embodiment, the allocation information of the time domain resources to be scheduled atypically includes the following two cases of description information for scheduling time domain resources.

[0077] First case:

[0078] The allocation information of the time domain resources to be scheduled includes the quantity information of the time domain resources to be scheduled; specifically, the quantity information of the time domain resources to be scheduled includes the time slot level quantity information for the time domain resources to be scheduled and / or the symbol level quantity information for the time domain resources to be scheduled. It should be explained that when used to characterize the quantity of time domain resources in time slots, it is called the time slot level quantity information of the time domain resources; when used to characterize the quantity of time domain resources in symbols, it is called the symbol level quantity information of the time domain resources.

[0079] Accordingly, when the allocation information of the time domain resources to be scheduled includes the quantity information of the time domain resources to be scheduled, see Figure 5 For the determination rule based on the setting described in S402, determining the corresponding time domain position for the time domain resource to be scheduled according to the uplink and downlink time domain resource configuration information and the allocation information may include:

[0080] S4021A: Determine a candidate time domain resource for the time domain resource to be scheduled according to the uplink and downlink time domain resource configuration information;

[0081] The number of the candidate time domain resources is consistent with the number of the time domain resources to be scheduled, and the candidate time domain resources do not conflict with the uplink and downlink time domain resource configuration information, and the conflict is that the transmission direction indicated by the uplink and downlink time domain resource configuration information is opposite to the channel transmission direction of the time domain resources to be scheduled;

[0082] S4022A: Fill the candidate time domain resources with the time domain resources to be scheduled, and determine the time domain position corresponding to the time domain resources to be scheduled.

[0083] In this case example, preferably, the filling of the time domain resources to be scheduled into the candidate time domain resources may include, during implementation: filling the time domain resources to be scheduled into the candidate time domain resources in sequence.

[0084] It should be noted that after the terminal learns the quantity information of the time domain resources to be scheduled, it can determine the candidate time domain resources that do not conflict with the uplink and downlink time domain resource configuration information, and then fill the time domain resources to be scheduled into the candidate time domain resources in sequence. It can be understood that since the quantity information of the time domain resources to be scheduled can be the time slot level quantity information and / or the symbol level quantity information, the terminal can also determine the candidate time domain resources according to the time slot level and / or the symbol level when determining the candidate time domain resources. After the terminal determines the time domain position corresponding to the time domain resources to be scheduled according to the above process, it is consistent with the scheduling information adjusted by the base station gNB for the time domain resources to be scheduled, so there is no need to perform signaling interaction in the channel transmission to notify the terminal of the adjusted scheduling information, which saves the signaling overhead between the base station gNB and the terminal, and avoids the increase in the probability of false detection caused by repeated transmission of control signaling.

[0085] Second case

[0086] The allocation information of the time domain resources to be scheduled includes the quantity information of the time domain resources to be scheduled and the pre-selected position information for each time domain resource to be scheduled. It can be understood that the quantity information and position information can be the quantity information and position information at the time slot level and / or symbol level, which will not be repeated here.

[0087] Accordingly, when the allocation information of the time domain resources to be scheduled includes the quantity information of the time domain resources to be scheduled and the pre-selected position information for the time domain resources to be scheduled, refer to Figure 6 For the determination rule based on the setting described in S402, determining the corresponding time domain position for the time domain resource to be scheduled according to the uplink and downlink time domain resource configuration information and the allocation information may include:

[0088] S4021B: Determine the conflicting time domain resource position from the pre-selected position information of each time domain resource to be scheduled according to the uplink and downlink time domain resource configuration information; wherein the conflicting time domain resource position is the time domain resource position in the uplink and downlink time domain resource configuration information that is opposite to the transmission direction of the time domain resource channel to be scheduled;

[0089] S4022B: Move the conflicting time domain resource position in the pre-selected position back to the non-conflicting time domain resource position closest to the conflicting time domain resource position; it can be understood that the non-conflicting time domain resource position is the time domain resource position in the uplink and downlink time domain resource configuration information that has the same transmission direction as the time domain resource channel to be scheduled;

[0090] S4023B: Shifting the preselected position after the conflicting time domain resource position in the preselected position backward according to the backward shift distance of the conflicting time domain resource position;

[0091] S4024B: Determine whether there is a conflicting time domain resource position in the pre-selected position after the shift according to the uplink and downlink time domain resource configuration information; if so, go to step S4022B until there is no conflicting time domain resource position in the pre-selected position after the shift, and execute step S4025B; otherwise, execute step S4025B;

[0092] S4025B: Fill the time domain resources to be scheduled into the pre-selected position after the backward shift in order, and determine the time domain position corresponding to the time domain resources to be scheduled.

[0093] It can be understood that when the preset position of the time domain resource to be scheduled in the time slot conflicts with the entire time slot position in the time domain configuration information, the preset position where the conflict occurs can be moved back to the nearest non-conflicting time slot position, and the preset position after the preset position where the conflict occurs can be moved back according to the backward distance of the preset position where the conflict occurs, so as to avoid the conflict.

[0094] In addition, since the position information can be symbol-level position information, when the preset position of the time domain resource to be scheduled in the time slot conflicts with some time slot positions in the time domain configuration information, the symbol where the preset position conflicts can be shifted back according to the above process, and the preset position after the preset position where the conflict occurs can be shifted back according to the shift distance of the preset position where the conflict occurs, and other preset positions where no conflict occurs will not change.

[0095] The method for determining time domain resources provided in this embodiment is that the terminal determines the time domain position corresponding to the time domain resources to be scheduled according to the determination rules pre-agreed with the base station, so that the determined time domain position is consistent with the scheduling information adjusted by the base station for the time domain resources to be scheduled. This not only enables the terminal to avoid conflicts with the time domain configuration information during channel transmission, which may cause the terminal to be unable to transmit the channel within a short period of time, but also saves the signaling overhead between the terminal and the base station during channel transmission, and avoids the increase in the probability of false detection caused by repeated sending of control signaling.

[0096] Embodiment 2

[0097] Based on the same inventive concept as the above embodiments, see Figure 7 , which shows a method flow for determining time domain resources provided by an embodiment of the present invention. The method can be applied to a network device, such as a base station gNB, etc. The method may include:

[0098] S701: Sending allocation information of time domain resources to be scheduled to the terminal;

[0099] The time domain resources to be scheduled include time domain resources that need to be used for channel transmission, and the allocation information is used by the terminal to determine the time domain position corresponding to the time domain resources to be scheduled.

[0100] S702: Perform channel transmission through the time domain resources to be scheduled according to the time domain positions corresponding to the time domain resources to be scheduled.

[0101] It needs to be explained that the channels may include data channels such as physical downlink shared channel (PDSCH) and physical uplink shared channel (PUSCH), and may also include control channels such as physical downlink control channel (PDCCH) and physical uplink control channel (PUCCH).

[0102] It can be understood that the base station finds that the scheduling information and configuration information of the time domain resources occur as follows Figure 2 or Figure 3After the conflict shown, the scheduling information of the time domain resources can be adjusted to avoid the conflict, and the terminal can determine the location information of the time domain resources to be scheduled according to the determination rules pre-negotiated with the base station, and make the same adjustment as the base station gNB, that is, the time domain location corresponding to the time domain resources to be scheduled determined by the terminal is consistent with the scheduling information after the base station gNB adjusts the time domain resources to be scheduled. Therefore, the base station can perform channel transmission with the terminal according to the time domain location corresponding to the time domain resources to be scheduled through the time domain resources to be scheduled, which not only avoids the situation where the terminal cannot transmit the channel in a short period of time due to the conflict between the scheduling information and the configuration information, but also does not need to notify the terminal, reducing the signaling overhead between the terminal and the base station gNB, and avoiding the increase in the probability of false detection caused by repeated transmission of control signaling.

[0103] In a possible implementation, the allocation information of the time domain resources to be scheduled can be carried in the downlink control information (DCI). It can be understood that DCI can be dynamically configured, so that the base station gNB can send the allocation information to the terminal in time, so that the terminal can determine the location of the time domain resources to be scheduled in time to avoid conflicts.

[0104] In a possible implementation, it may also include: sending uplink and downlink time domain resource configuration information to the terminal; wherein the uplink and downlink time domain resource configuration information includes time slot level position information and / or symbol level position information of available time domain resources. It should be explained that when used to characterize the position of the time domain resource in time slots, it is called the time slot level position information of the time domain resource; when used to characterize the position information of the time domain resource in symbols, it is called the symbol level position information of the time domain resource.

[0105] Specifically, the uplink and downlink time domain resource configuration information may be predefined information, or may be carried in radio resource control (RRC) signaling and / or DCI. In specific implementation, it may be frame structure information and / or a slot format indicator (SFI).

[0106] for Figure 7The technical solution shown needs to be explained that the allocation information of the time domain resources to be scheduled is not the scheduling information adjusted by the base station gNB for the time domain resources to be scheduled, but the description information for the time domain resources to be scheduled. After the terminal obtains the description information for the time domain resources to be scheduled, it determines the time domain position corresponding to the time domain resources to be scheduled according to the determination rule obtained and agreed with the base station gNB, so that the time domain position corresponding to the time domain resources to be scheduled finally determined by the terminal is consistent with the scheduling information adjusted by the base station gNB for the time domain resources to be scheduled. Therefore, there is no need for the base station to notify the terminal of the scheduling information adjusted for the time domain resources to be scheduled during the channel transmission process, saving the signaling overhead between the base station gNB and the terminal during the channel transmission process. Therefore, in an atypical example, the allocation information of the time domain resources to be scheduled includes the quantity information of the time domain resources to be scheduled; or, the allocation information of the time domain resources to be scheduled includes the quantity information of the time domain resources to be scheduled and the pre-selected position information for each time domain resource to be scheduled.

[0107] The method for determining time domain resources provided in this embodiment is that the network device sends allocation information of the time domain resources to be scheduled to the terminal, so that the terminal determines the time domain position corresponding to the time domain resources to be scheduled, so that the terminal can perform channel transmission with the terminal through the time domain resources to be scheduled according to the time domain position corresponding to the time domain resources to be scheduled, which not only avoids the situation where the terminal cannot transmit the channel within a short period of time due to the conflict between the scheduling information and the configuration information, but also eliminates the need to notify the terminal, reduces the signaling overhead between the terminal and the base station gNB, and avoids the increase in the probability of false detection caused by repeated sending of control signaling.

[0108] Embodiment 3

[0109] Based on the same inventive concept as the above-mentioned embodiment, this embodiment illustrates the technical solution of the above-mentioned embodiment through the following specific examples. It should be noted that the following specific examples are all illustrated by using the time domain resources to be scheduled for transmitting downlink data channels, such as PDSCH, and the network device is illustrated by the base station gNB. It can be understood that in actual application, the time domain resources to be scheduled can also be used to transmit uplink data channels, such as PUSCH, uplink or downlink control channels, such as PDCCH or PUCCH, and the specific examples in this embodiment will not be repeated.

[0110] Specific example 1

[0111] by Figure 8 For example, it should be noted that Figure 8 The first behavior Figure 8 pictorial information.

[0112] The base station gNB sends allocation information of the time domain resources to be scheduled to the terminal. The allocation information may be a DL grant, and the allocation information includes the quantity information of the time domain resources to be scheduled, such as Figure 8 As shown in the gray box in the second row of . Since the quantity information can be at the time slot level or the symbol level, the total number of time domain resources to be scheduled is 2 time slots plus a number of symbols. In this embodiment, the aforementioned number of symbols is described by taking 10 symbols as an example. Therefore, after the terminal obtains the quantity information of the resources to be scheduled, it determines the candidate time domain resources according to the known uplink and downlink time domain resource configuration information, such as Figure 8 As shown in the distribution of the gray blocks in the third row, it should be noted that the uplink and downlink time domain resource configuration information may specifically be DL / ULassignment. Figure 8 It can be seen from the uplink and downlink time domain resource configuration information shown in the fourth row that the last several symbols of time slot 1 and the entire time slot 2 are used to transmit uplink channels or other time domain resource areas, which will conflict with the transmission of PDSCH. Therefore, when determining the candidate time domain resources, the terminal will avoid the conflicting area, and then the terminal will distribute the time domain resources to be scheduled in the candidate time domain resources in order, thereby determining the time domain position of the time domain resources used to transmit PDSCH.

[0113] Specific example 2

[0114] by Fig. 9 For example, it should be noted that Fig. 9 The first behavior Fig. 9 pictorial information.

[0115] The base station gNB sends allocation information of the time domain resources to be scheduled to the terminal. The allocation information may be a DL grant. The allocation information includes not only the quantity information of the time domain resources to be scheduled, but also the pre-selected position information for each time domain resource to be scheduled, such as Fig. 9 After receiving the allocation information, the terminal will combine the pre-selected location information with Fig. 9 By comparing the known uplink and downlink time domain resource configuration information shown in the fourth row of , it is found that time slot 2 is used to transmit uplink channels or other time domain resource areas, which will conflict with the transmission of PDSCH. Therefore, the terminal moves the preset position corresponding to time slot 2 where the conflict occurs to the nearest non-conflicting position of time slot 2, that is, time slot 3, and moves the preset positions after the conflicting preset position according to the conflicting preset position to avoid the conflict. Fig. 9 As shown in the third row of . When the pre-selected position is shifted backward, the terminal fills the time domain resources to be scheduled into the pre-selected position that has been shifted backward in order, thereby determining the time domain position corresponding to the resources to be scheduled.

[0116] Specific example three

[0117] by Fig.10 For example, it should be noted that Fig.10 The first behavior Fig.10 pictorial information.

[0118] Similar to the specific example 2, the base station gNB sends allocation information of the time domain resources to be scheduled to the terminal. The allocation information may be a DL grant. The allocation information includes not only the quantity information of the time domain resources to be scheduled, but also the pre-selected position information for each time domain resource to be scheduled, such as Fig.10 After receiving the allocation information, the terminal will combine the pre-selected location information with Fig.10 However, in this specific example, the latter part of time slot 2 conflicts with some preset positions of the time domain resources to be scheduled. Therefore, the terminal will move the symbols where the preset positions conflict to the nearest non-conflicting time slot position, and the preset positions after the preset positions where the conflict occurs will be moved back according to the backward movement distance of the preset positions where the conflict occurs. Other preset positions where no conflict occurs will not be changed to avoid conflicts. Fig.10 When the pre-selected position is shifted backward, the terminal still fills the time domain resources to be scheduled to the pre-selected position that has been shifted backward in sequence according to the process described in the specific example 2, thereby determining the time domain position corresponding to the resources to be scheduled.

[0119] The above three specific examples illustrate the specific implementation of the technical solution of the aforementioned embodiment in detail. It can be seen that the terminal can determine the time domain position of the time domain resources to be scheduled through the allocation information sent by the base station, thereby avoiding the occurrence of conflicts. Moreover, since the result determined by the terminal is consistent with the result after the scheduling adjustment of the base station, the terminal and the base station no longer need to interact through signaling to obtain the result of the time domain resource scheduling adjustment of the base station during channel transmission, which saves signaling overhead and avoids the increase in the probability of false detection caused by repeated sending of control signaling.
