However, the specific parameter implementation of these configuration methods has not been discussed in detail in the standard, but is left to the implementer in the actual deployment to decide.

However, it should also be understood that determining B according to A does not mean determining B only according to A, and B can also be determined according to A and / or other information.

[0079] Next, the related technologies will be introduced.

[0080] Related parameter configuration in the NR-V2X standard:

[0081] The configuration period of the PSFCH is the periodic interval at which the PSFCH resource appears, and this interval is the number of logical subframes. The configuration period of the PSFCH being N means that the PSFCH resource will appear only once every N logical subframes. In order to balance resource overhead and system capacity, the standard provides several candidate configurations, including N = 1, N = 2, N = 4, and N = ∞ (indicating no PSFCH resource configuration). Among them, the N value, as a key parameter for resource pool configuration, determines the distribution of the PSFCH resource in the time domain, that is, the configuration of the PSFCH resource appears once every N logical time slots (slots). In the frequency domain, the position of the PSFCH resource is configured through the set of physical resource blocks (PRBs) indicated by a bitmap, specifically as Figure 1 shown, which is a schematic diagram of the time-domain configuration of the PSFCH resource when N = 2.

[0082] More specifically, within a resource pool, there are two cases of HARQ feedback configuration, namely enabling HARQ feedback and disabling HARQ feedback, and this configuration is indicated by the SCI. Among them, if HARQ feedback is enabled, then the PSFCH resources need to be configured in this resource pool. At this time, the value range of the PSFCH period parameter N is {1, 2, 4}, and the HARQ feedback can only be transmitted through the PSFCH channel in this resource pool. When N > 1, multiple PSSCHs will be mapped to the same PSFCH resource; if HARQ feedback is not enabled, then a resource pool without PSFCH resources can be selected.

[0083] The mapping of PSFCH resources also needs to meet the requirements of parameter K. Among them, K is defined as the minimum time interval / feedback interval between PSSCH and PSFCH, and this parameter reflects the processing ability of the User Equipment (UE). The definition of parameter K is also based on the number of logical sub-frames and is part of the resource pool configuration, and its value range is K = {2, 3}.

[0084] The following is illustrated by a specific example:

[0085] As Figure 2 shown, assume that the feedback period of the PSFCH resource is 1 (i.e., N = 1), and the minimum time interval is 3 (i.e., K = 3).

[0086] The time-domain configuration of the resource pool is implemented through a Bitmap, and the length of the Bitmap can be flexibly configured according to requirements. Specifically, the resource pool supports discontinuous time slot configurations, where the time slot is the smallest granularity of the time-domain configuration. For the set of time slots configured in the resource pool, the period is 10240 ms, and the length of the Bitmap can be configured within the range of {10, 11, 12,..., 160}.

[0087]

[0088] The above code represents the time resource configuration bitmap (Bitmap) of the resource pool. This bitmap is defined by repeating periodically within the System Frame Number (SFN) or Direct Frame Number (DFN) period.

[0089] The process of determining the feedback resource is as follows:

[0090] (1) Determine the logical sub-frame:

[0091] When configuring time slots (slots) in the resource pool, the following types of time slots need to be excluded:

[0092] 1) Slots of Sidelink Synchronization Signal (SLSS);

[0093] 2) Slots with the number of consecutive available Uplink (UL) symbols less than X;

[0094] 3) Reserved slots: The time slots reserved by the system. After excluding the first two types of time slots, the number of slots corresponding to 10240 ms is the time domain resource obtained by taking the remainder of the remaining time domain resources after excluding the first two types of time slots by the length of the bitmap, and it is necessary to ensure that the distribution of the reserved slots is even.

[0095] (2) Determine the feedback resources:

[0096] For the resource mapping of PSFCH, an implicit association method with the corresponding PSSCH is adopted, and the information such as the corresponding PSSCH sub-channel and UE member ID is used to determine the PSFCH resource position. Specifically, the calculation process of the PSFCH feedback resources is as follows:

[0097] Step1: Use the sliding window mechanism to determine the PSFCH period corresponding to each PSSCH transmission.

[0098] Specifically, the PSSCH corresponding to each PSFCH slot is within a sliding window.

[0099] Step2: Determine the set of PSFCH PRB frequency domain resources within the PSFCH period, denoted as

[0100] Specifically, the higher layer parameter configuration function rbSetPSFCH() is used to configure the parameters related to PSFCH. The specific configuration content includes: the number of sub-channels (S) included in the resource pool; an integer multiple of the PSFCH resource period (N), that is, a fixed number of PRBs are allocated to each sub-channel within the period.

[0101] A certain number of PRBs are allocated to each sub-channel on each slot within the period, that is, the number of corresponding PSFCH resources / PRBs is:

[0102] Step 3: Determine the relative slot number I within the PSFCH period corresponding to the PSSCH resource, and determine the relative sub-channel or relative set number j of the sub-channel set. According to I and j, determine the PSFCH PRB set corresponding to a Transport Block (TB) from the PSFCH PRB frequency-domain resource set within the corresponding PSFCH period, denoted as

[0103] Specifically, during the resource allocation process, allocation is prioritized in the frequency domain first, and then in the time domain. The resource allocation formula is:

[0104]

[0105] Among them, if the high-layer parameter configuration is the first sub-channel, determine the corresponding PRB set; if the high-layer parameter configuration is a sub-channel, determine the set of corresponding PRB sets.

[0106] Step 4: Combine the context information and the high-layer configuration message to determine the PSFCH resource set corresponding to the TB Including: Specifically, the time domain, frequency domain, and the number of cyclic shifts.

[0107] Specifically, after determining the PSFCH candidate resource set, it is necessary to further determine the resources for PSFCH transmission. The basic principle is frequency-domain priority, that is, different PRBs are preferentially selected for PSFCH transmission. The specific determination method is as follows:

[0108]

[0109] Among them, K / P ID: The truncated layer-2 source ID (source ID) carried in the SCI associated with the PSSCH sent by the Transmitting User Equipment (TX UE). MID / M (member ID): Has different values according to different HARQ feedback modes. Among them, for unicast, M = 0, and knowing its own source ID, it can also be calculated; in multicast HARQ feedback option 1, M = 0; knowing its own source ID and member ID (member ID) can also be calculated; in multicast HARQ feedback option 2, M is the multicast member ID of the Receiving User Equipment (RX UE). Furthermore, it can be determined which cyclic shift the specific resource is, corresponding to the specific PRB and codeword.

[0110] Step 5: Determine the final codebook according to the feedback type and the corresponding cyclic shift index.

[0111] Specifically, for the receiving feedback end, all possibilities need to be considered. For example, under Acknowledgment (ACK) / Negative Acknowledgment (NACK), the resources carrying ACK and NACK need to be considered in advance; for NACK only, the resources carrying NACK need to be considered in advance.

[0112] Currently, the parameter configuration in the standard is flexible, and the PSFCH period and the bitmap length configuration are independently configured. Therefore, there may be a problem that the two parameter configurations are not coordinated. For example, the PSFCH period is configured as 4, but the bitmap length is configured as 11, that is, the number of logical subframes within 10240 ms is a multiple of 11, but a multiple of 11 is not necessarily a multiple of 4.

[0113] Here, a specific example is given for illustration:

[0114] Scenario 1: Assume that within 10240 ms (assume the configuration is 10240 slots, that is, 1 slot within 1 subframe), after removing the special slots and reserved slots, there are 10230 logical slots left. 10230 is a multiple of 11 (930 bitmaps), but 10230 is not a multiple of 4.

[0115] Scenario 2: Assume that within 10240 ms (assume the configuration is 10240 slots, that is, 1 slot within 1 subframe), after removing the special slots and reserved slots, there are 10208 logical slots left. 10208 is both a multiple of 11 and a multiple of 4.

[0116] Here, the scenario where it is a multiple of the bitmap but not a multiple of the PSFCH period (such as Scenario 1 above) is mainly discussed. Some problems will occur in this scenario, and a practical example is used to illustrate here.

[0117] If the configuration is reasonable, taking 10,208 logical sub-frames as an example: The last PSFCH window is {the 10,225th logical slot, the 10,226th logical slot, the 10,227th logical slot, the 10,228th logical slot}, and the feedback resource period is 4, that is, the feedback resource is configured only on the 10,228th logical slot. The numbering restarts for the next super-frame (1020 ms period), {the 1st logical slot, the 2nd logical slot, the 3rd logical slot, the 4th logical slot}, that is, the PSFCH resource is configured only on the 4th logical slot. For the 10,227th logical slot, the 10,228th logical slot, the 1st logical slot, and the 2nd logical slot, if in accordance with the standard regulations, the PSFCH resources will all be mapped to the 4th logical slot, that is, the implicit window length is still 4 logical slots.

[0118] If the configuration is unreasonable, assuming that the bitmap length is configured as 11 and the PSFCH period is configured as 4, there are 10,230 logical slots among 10,240 slots; K = 2; the 10,230th logical slot, but the last PSFCH window is {the 10,225th logical slot, the 10,226th logical slot, the 10,227th logical slot, the 10,228}, and the feedback resource period is 4 logical sub-frames, that is, the feedback resource is available only on the 10,228th logical slot; for the 10,229th logical slot and the 10,330th logical slot, it is not a complete cycle and there is no PSFCH resource; the numbering restarts for the next super-frame, {the 1st logical slot, the 2nd logical slot, the 3rd logical slot, the 4th logical slot}, that is, the PSFCH resource is configured only on the 4th logical slot. For the 10,227th logical slot, the 10,228th logical slot, the 10,229th logical slot, the 10,230th logical slot, the 1st logical slot, and the 2nd logical slot, if in accordance with the standard regulations, the PSFCH resources will all be mapped to the 4th logical slot; the following problems will occur:

[0119] (1) Collision of feedback resources: Compared with one-to-one mapping, the resource mapping on 2 additional slots is added here, which will cause some unnecessary problems, that is, there will be some collisions caused by multiplexing in this mapping.

[0120]

[0121]

[0122] (2) If multiplexing occurs at the receiving end, feedback message judgment errors may occur at the service message sender and the feedback message receiver, which will affect system performance.

[0123] (3) Calculation of the round-trip time (RTT), that is, the interval between different transmissions of service packets. For example, for the 10227th logical slot, the feedback can be received in the 4th logical slot, which is 7 logical slots away. If the maximum interval is 5 logical slots under normal configuration, the sender may retransmit the packet again between the 4th logical slot.

[0124] In summary, if the configuration parameters of the PSFCH period and resource pool are not configured reasonably, a series of problems may occur, and the prior art lacks reasonable principles for the configuration of the PSFCH period and resource pool.

[0125] Specifically, the embodiments of the present invention provide a resource configuration and scheduling method, apparatus, processing device, program product and medium, which solve the resource conflict problem in the prior art caused by the uncoordinated PSFCH period and resource pool configuration.

[0126] First embodiment

[0127] like Figure 3 As shown, an embodiment of the present invention provides a resource configuration and scheduling method, which specifically includes the following steps:

[0128] Step 31: According to the preset rules, perform resource configuration of the time domain period and the time domain length, wherein the time domain period is the time domain period of the physical sidelink feedback channel PSFCH, and the time domain length is the time domain length of the bitmap corresponding to the resource pool. The preset rules include at least one of the following:

[0129] (1) The time domain length is an integer multiple of the time domain period.

[0130] It should be noted that when configuring the resource pool related parameters (such as the above-mentioned time domain period and time domain length), try to optimize the configuration and give priority to configuring the time domain length of the bitmap as an integer multiple of the PSFCH time domain period. For example, if the PSFCH time domain period is configured to 1, the bitmap length (that is, the time domain length of the bitmap) can be configured arbitrarily; if the PSFCH time domain period is configured to 2, the time domain length of the bitmap needs to be configured to an even number; if the PSFCH time domain period is configured to 4, the time domain length of the bitmap needs to be configured to a multiple of 4.

[0131] (2) The time domain period and the time domain length are not integer multiples, and the total number of logical subframes in a superframe is a common multiple of the time domain period and the time domain length.

[0132] That is to say, if the time domain length of the bitmap is not an integer multiple of the PSFCH time domain period, the number of logical sub-frames within the superframe needs to be configured as the least common multiple of the bitmap length (i.e., the time domain length of the bitmap) and the PSFCH time domain period.

[0133] Here, the length of the superframe can specifically be 10240 ms (that is, one superframe contains 1024 sub-frames). The length of the slot contained in the superframe may be 10240 or 20480, etc., specifically depending on the sub-carrier spacing configuration. Example: If the sub-carrier spacing (SCS) is 15 kHz (time slot = 1 ms), then the superframe (10240 ms) contains 10240 time slots; if SCS = 30 kHz (time slot = 0.5 ms), then the superframe contains 20480 time slots.

[0134] In an optional example, the bitmap length is configured as 11, the PSFCH time domain period is configured as 4, and the number of logical slots within the superframe (10240 ms) is a multiple of 44 (44 is the least common multiple of the two parameters 11 and 4). In this way, the entire PSFCH small window is also evenly distributed.

[0135] Step 32: Perform resource scheduling and feedback decision-making according to the resource configuration.

[0136] In this embodiment, the resource configuration of the time domain period and the time domain length can be performed according to a preset rule, that is, the time domain length is an integer multiple of the time domain period, or there is a non-integer multiple relationship between the time domain period and the time domain length, but the total number of logical sub-frames within the superframe is the least common multiple of the time domain period and the time domain length. In this way, through reasonable configuration, the situation of resource conflict caused by the logical sub-frame interval between PSSCH and PSFCH exceeding the maximum RTT configuration can be effectively avoided. Specifically, the following two abnormal situations can be effectively avoided: 1) The PSFCH symbol resource conflict caused by the cross-period mapping of PSSCH resources (that is, the PSSCH resources on more than the number of PSFCH periods of slots are mapped to the same PSFCH symbol resource); 2) The sending end has repeated transmissions within the logical sub-frame interval (that is, the resource selection meets the maximum RTT limit but is less than the actual interval, triggering an unexpected secondary transmission).

[0137] In some embodiments, the performing resource scheduling and feedback decision-making according to the resource configuration includes:

[0138] In the case where it is detected that the time domain period and the time domain length do not meet the preset rule, for the target time slot, perform resource scheduling optimization and / or feedback decision-making optimization.

[0139] That is to say, when the resource allocation fails to meet the preset rules, to avoid resource conflicts, it can be handled by active avoidance (i.e., resource scheduling optimization) or passive resolution (i.e., feedback decision optimization) to avoid resource conflicts. Specifically, it is necessary to determine the situation of superframe flipping (which can be judged by the frame number at a higher layer) to determine whether resource scheduling optimization and / or feedback decision optimization is required.

[0140] Among them, the target time slot includes: when allocating feedback resources based on the standard mapping rule from the physical sidelink shared channel PSSCH to PSFCH, due to superframe flipping across the cycle boundary, and the time slot offset between PSSCH and PSFCH exceeds the PSSCH time slot with the preset maximum round-trip time (RTT) constraint.

[0141] It should be noted that according to the existing standard, the maximum RTT can be calculated according to the following formula: maximum RTT = (sl - MinTimeGapPSFCH + (sl - PSFCH - Period - 1)). Where sl - MinTimeGapPSFCH represents the minimum interval, and sl - PSFCH - Period represents the time domain period of PSFCH. For example, assuming the time domain period of PSFCH is 4, if the minimum interval is 3, then the maximum RTT is 6. Another example, if the minimum interval is 2, then the maximum RTT is 5.

[0142] In some embodiments, for the target time slot, resource scheduling optimization is performed, including:

[0143] (1) Before performing resource scheduling, determine whether the triggering conditions corresponding to special resource scheduling processing are met; among them, the triggering conditions include at least one of the following:

[0144] (1) The resource selection window contains the superframe flipping moment;

[0145] (2) The resource selection window does not contain the superframe flipping moment, and the time interval starting from the last time slot of the resource selection window and with a duration equal to the maximum RTT crosses the superframe flipping moment;

[0146] (3) The time interval from the service packet arrival time point to the time point corresponding to the service maximum packet delay budget (PDB) crosses the superframe flipping moment.

[0147] (2) When it is determined that the triggering conditions are met, determine the target time slot.

[0148] In the embodiments of the present invention, to avoid invalid calculations, the target time slot is calculated only when it is determined that the triggering conditions are met. That is to say, when the triggering conditions are met, it is possible to select the target time slot.

[0149] (3) Determine the target scheduling strategy corresponding to the target time slot.

[0150] In some specific embodiments of the present invention, the target scheduling strategy includes: prohibiting scheduling the target time slot to send a service message that requires hybrid automatic repeat request HARQ feedback.

[0151] That is to say, the target time slot should be calculated in advance when selecting resources, and information that requires feedback should be avoided as much as possible in the target time slot. It is understandable that this is limited to situations where feedback is required. For service messages that do not require feedback, the target time slot can still be scheduled for transmission. It should also be noted that the transmission here includes the transmission to be sent and the scheduled transmission within the TB. If the frame number flip is about to occur based on the high-level subframe number, if it is a feedback-based service transmission, avoid scheduling the target time slot to send information that requires feedback.

[0152] In a specific embodiment, assuming that the PSFCH period (i.e., the time domain period of PSFCH) is configured as 4, but the bitmap length (i.e., the time domain length of the bitmap) is configured as 11, and the length of the superframe is 10240ms (assuming that it is configured as 10240 slots, i.e., 1 slot in 1 subframe), after removing the special slots and reserved slots, 10230 logical slots remain. 10230 is a multiple of 11 (930 bitmaps), but 10230 is not a multiple of 4. According to the slot where the feedback resource is located, it can be concluded that the 10227th logical slot and the 10228th logical slot are the target time slots, and the intervals between these two logical slots and the corresponding feedback resources are greater than the maximum RTT. Service messages can be sent only on the basis of synchronization. To avoid misalignment, resources within the PSFCH irregular period should be avoided as much as possible during resource selection. In this embodiment, the 10227th logical slot and the 10228th logical slot should be avoided.

[0153] In some embodiments, feedback decision optimization is performed for the target time slot, including:

[0154] According to the time slot where the PSSCH is located and the side link control information SCI, the first feedback resource corresponding to the first service message is determined; if it is determined that the first feedback resource spans a superframe, it is determined whether the first PSSCH time slot corresponding to the first service message is the target time slot; if it is determined that the first PSSCH time slot is the target time slot, the target feedback strategy is determined according to the HARQ combined reception result corresponding to the first service message and the feedback method indicated by the service sending end.

[0155] Here, the service sending end (service message sending end) can indicate the feedback mode through SCI.

[0156] It should be noted that for the service receiving end (service message receiving end), HARQ combining can be performed from the perspective of service message reception. For PSFCH feedback, in order to avoid interference, special processing can be done, that is, feedback decision optimization is performed to passively solve the problem. That is to say, if the corresponding service message is received in the target time slot, the corresponding HARQ processing needs to be performed, and the corresponding special processing for the feedback (that is, the target feedback strategy is executed).

[0157] It should also be noted that the above service sending end and service receiving end can be network devices (such as base stations), or terminal devices. For example, in an optional example, the service sending end is a terminal and the service receiving end is a network device; in another optional example, the service sending end is a network device and the service receiving end is a terminal.

[0158] In some embodiments, the target feedback strategy includes at least one of the following:

[0159] (1) If the service sending end indicates to adopt a feedback method based on acknowledgment ACK / negative acknowledgment NACK, no feedback information is sent at the feedback resource position corresponding to the target time slot;

[0160] That is to say, if the ACK / NACK based feedback method is adopted, no feedback information is sent regardless of whether the HARQ combining is received successfully or not.

[0161] (2) If the service sending end indicates to adopt a feedback method based on NACK, and the HARQ combining reception result is correct, no feedback information is sent at the feedback resource position corresponding to the target time slot;

[0162] (3) If the service sending end indicates to adopt a feedback method based on NACK, and the HARQ combining reception result is incorrect, NACK feedback information is sent at the feedback resource position corresponding to the target time slot.

[0163] Wherein, the feedback information includes: ACK feedback information and / or the NACK feedback information.

[0164] That is to say, if the NACK based feedback method is adopted, if the HARQ combining reception is correct, no feedback is made (that is, no feedback information is sent at the PSFCH resource position corresponding to the target time slot); if the HARQ combining reception is incorrect, NACK feedback is made (that is, NACK feedback information is sent at the PSFCH resource position corresponding to the target time slot).

[0165] The resource configuration and scheduling method implemented in the present invention provides reasonable configuration principles (i.e., preset rules), as well as some protection processing methods (such as active solutions and passive solutions) when the configuration principles are not met. Specifically, when performing resource configuration and scheduling, the priority order of "configuration>active solution>passive solution" is followed. That is to say, first of all, through a reasonable configuration method (i.e., resource configuration of time domain period and time domain length according to preset rules), the occurrence of resource conflict problems caused by the incoordination of PSFCH period and resource pool configuration is prevented. This is the most effective and lowest cost method; secondly, if the resource conflict problem has occurred due to unreasonable configuration, active measures can be taken to solve it (such as timely monitoring, determining the target time slot and optimizing resource scheduling for the target time slot) to reduce the impact on the system, rather than waiting for the problem to worsen; finally, if the first two methods cannot be implemented or the effect is not good, passive solutions can be considered, that is, responding and handling after the problem occurs (such as feedback decision optimization for the target time slot). Following the above priority order can maximize the stability and efficiency of the system and reduce unnecessary waste of resources.

[0166] The resource configuration and scheduling method of the embodiment of the present invention can perform resource configuration of the time domain period and the time domain length according to the preset rules, that is, the time domain length is an integer multiple of the time domain period, or the time domain period and the time domain length are non-integer multiples, but the total number of logical subframes in the superframe is a common multiple of the time domain period and the time domain length. In this way, through reasonable configuration, the situation where the logical subframe interval between PSSCH and PSFCH exceeds the maximum RTT configuration and causes resource conflicts can be effectively avoided. Specifically, the following two abnormal situations can be effectively avoided: 1) PSFCH symbol resource conflicts caused by cross-period mapping of PSSCH resources (that is, PSSCH resources on slots exceeding the number of PSFCH periods are mapped to the same PSFCH symbol resources); 2) The transmitting end has repeated transmissions within the logical subframe interval (that is, the resource selection meets the maximum RTT limit but is less than the actual interval, triggering unexpected secondary transmissions). If it is not configured according to the preset rules, resource conflicts can be avoided by actively optimizing resource scheduling or passively optimizing feedback decisions. Through the above method, resource conflicts caused by inconsistent PSFCH period and resource pool configuration can be effectively avoided.

[0167] Second embodiment

[0168] like Figure 4 As shown, an embodiment of the present invention provides a resource configuration and scheduling device 400, including:

[0169] A period determination module 401 is configured to perform resource allocation for a time domain period and a time domain length according to a preset rule. The time domain period is the time domain period of a physical side link feedback channel (PSFCH), and the time domain length is the time domain length of a bitmap corresponding to a resource pool.

[0173] There is no integer multiple relationship between the time domain period and the time domain length, and the total number of logical subframes in a superframe is a common multiple of the time domain period and the time domain length.

[0174] In this embodiment, resource allocation for the time domain period and the time domain length can be performed according to a preset rule, that is, the time domain length is an integer multiple of the time domain period, or there is no integer multiple relationship between the time domain period and the time domain length, but the total number of logical subframes in a superframe is a common multiple of the time domain period and the time domain length. In this way, through reasonable configuration, it is possible to effectively avoid the situation of resource conflict caused by the logical subframe interval between PSSCH and PSFCH exceeding the maximum RTT configuration. Specifically, the following two abnormal situations can be effectively avoided: 1) PSFCH symbol resource conflict caused by cross-period mapping of PSSCH resources (that is, PSSCH resources on more than the number of PSFCH periods of slots are mapped to the same PSFCH symbol resource); 2) Repeated transmission occurs in the logical subframe interval at the sending end (that is, the resource selection meets the maximum RTT limit but is less than the actual interval, triggering unexpected secondary transmission).

[0183] Wherein, the trigger condition includes at least one of the following:

[0192] A fourth processing unit, configured to determine a target feedback policy according to the HARQ combined reception result corresponding to the first service message and the feedback mode indicated by the service sending end if it is determined that the first PSSCH time slot is the target time slot.

[0194] If the service sending end indicates to adopt a feedback mode based on acknowledgment ACK / non-acknowledgment NACK, no feedback information is sent at the feedback resource position corresponding to the target time slot;

[0195] If the service sending end indicates to adopt a NACK-based feedback manner and the HARQ combined reception result is correct, the feedback information is not sent at the feedback resource position corresponding to the target time slot;

[0196] If the service sending end indicates to adopt a NACK-based feedback manner and the HARQ combined reception result is incorrect, a NACK feedback information is sent at the feedback resource position corresponding to the target time slot;

[0197] Wherein, the feedback information includes: ACK feedback information and / or the NACK feedback information.

[0198] The second embodiment of the present invention corresponds to the method of the above first embodiment. All the implementation means in the above first embodiment are applicable to the embodiment of the resource configuration and scheduling device, and can also achieve the same technical effect.

[0199] Third Embodiment

[0202] Wherein, a transceiver 510 is connected to the bus interface for receiving and sending data under the control of the processor 500; the processor 500 is used to read the programs in the memory 520 and execute the following steps:

In this way, through reasonable configuration, it is possible to effectively avoid the situation where the logical subframe interval between the PSSCH and the PSFCH exceeds the maximum RTT configuration, resulting in resource conflicts. Specifically, the following two abnormal situations can be effectively avoided: 1) The PSFCH symbol resource conflict caused by the cross-period mapping of the PSSCH resources (that is, the PSSCH resources on more than the number of PSFCH periods of slots are mapped to the same PSFCH symbol resource); 2) The transmitter performs repeated transmissions within the logical subframe interval (that is, the resource selection meets the maximum RTT limit but is less than the actual interval, triggering an unexpected secondary transmission).
