[0003] The present invention is based on PCT international application with application number PCT / CN2020 / 075431 and application date 2020-02-14 and PCT international application with application number PCT / CN2020 / 079061 and application date 2020-03-12, and claims the priority of the aforementioned PCT international application. The entire contents of the PCT international application are hereby introduced into the present invention as a reference. Technical Field

[0004] The present invention relates to the field of communications, and in particular to an information processing method, device, storage medium, processor and electronic device. Background Art

[0005] At present, in the related technology, in the process of determining the hybrid automatic repeat request (HARQ) process number in the new wireless (New Radio, NR) Uu system, the base station can allocate semi-static scheduling (SPS) downlink transmission resources to the terminal. When the base station configures the downlink SPS transmission resources, multiple HARQ process numbers can be configured for each set of SPS transmission resources. In addition, in the NR system, the base station can also allocate an uplink configured grant (UL CG) to the terminal. When the base station configures the UL CG resources, multiple HARQ process numbers can be configured for each set of UL CG resources.

[0006] It can be seen that the relevant technology only provides a method for determining the HARQ process number when the base station configures downlink SPS transmission resources or UL CG resources, but does not involve a method for determining the HARQ process number for the sideline (SL) configured grant (Configured Grant, referred to as CG).

[0120] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0121] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0122] Figure 1 is a schematic diagram of a D2D transmission technology according to related art, such as Figure 1As shown in the figure, device to device (D2D) communication is a sidelink (SL) transmission technology, which is different from the traditional cellular system in which communication data is received or sent through a base station. Since the D2D system uses terminal to terminal direct communication, it has higher spectrum efficiency and lower transmission latency. The Internet of Vehicles system is based on D2D transmission technology, and two transmission modes, Mode A and Mode B, are defined in the Third Generation Partnership Project (3GPP).

[0123] In mode A, the transmission resources of the terminal are allocated by the base station. The terminal transmits data on the sidelink according to the resources allocated by the base station. The base station can allocate resources for single transmission or semi-static transmission to the terminal. In mode B, the terminal selects a resource in the resource pool for data transmission.

[0124] In NR-Vehicle to Everything (V2X), the need to support autonomous driving places higher requirements on data interaction between vehicles, such as higher throughput, lower latency, higher reliability, larger coverage, more flexible resource allocation, etc. In NR-V2X, unicast and multicast transmission modes are introduced. In addition, in Long Term Evaluation (LTE)-V2X, broadcast transmission mode is also supported.

[0125] For the unicast transmission mode, unicast transmission is performed between the sending terminal and the receiving terminal. Figure 2 is a schematic diagram of a unicast transmission method according to the related art, such as Figure 2 As shown, UE1 is a sending side terminal, and UE2 is a receiving side terminal, so unicast transmission can be performed between UE1 and UE2.

[0126] For the multicast transmission mode, the receiving-side terminals include all terminals in a communication group or all terminals within a certain transmission distance. Figure 3 is a schematic diagram of a multicast transmission method according to related technologies, such as Figure 3 As shown, UE1, UE2, UE3 and UE4 constitute a communication group, wherein UE1 is a data transmitter, and other terminal devices UE2, UE3 and UE4 in the group are receiving-side terminals.

[0127] For the broadcast transmission mode, the receiving terminal can be any terminal. Figure 4 is a schematic diagram of a broadcast transmission method according to related technologies, such as Figure 4As shown, if UE1 is a sending-side terminal, other terminals UE2, UE3 and UE4 around UE1 can all be set as receiving-side terminals.

[0128] In addition, multiple transmission modes are introduced in NR-V2X, namely Mode 1 and Mode 2. Mode 1 is that the network allocates transmission resources to the terminal (i.e., Mode A mentioned above), and Mode 2 is that the terminal selects transmission resources (i.e., Mode B mentioned above). In order to improve the reliability of data transmission, a feedback channel is introduced on the sidelink. Figure 5 is a schematic diagram of the data transmission process in NR-V2X according to the related art, such as Figure 5 As shown, UE1 and UE2 form a unicast link. UE1 sends sidelink data to UE2. UE2 sends sidelink feedback information, i.e., HARQ ACK or NACK, to UE1 based on the detection result of the received sidelink data. After receiving the feedback information from UE2, UE1 decides whether to retransmit the data to UE2. In addition, UE1 can also decide whether the receiving side terminal UE2 needs to send feedback information. For example, for broadcast communication, the receiving end does not need to provide feedback; however, for unicast communication, in order to improve the reliability of the system, the receiving end needs to provide feedback. Specifically, UE1 carries indication information in the sidelink control information (Sidelink Control Information, referred to as SCI) to indicate whether the receiving side terminal needs to provide sidelink feedback.

[0129] In NR-V2X, resource allocation methods of Mode 1 and Mode 2 are also supported. In Mode 2, the terminal autonomously selects transmission resources from the resource pool for side transmission, which is the above-mentioned Mode B. In Mode 1, the network-side device allocates side configuration authorization transmission resources to the terminal, which is the above-mentioned Mode A. Specifically, the network-side device can allocate side configuration authorization transmission resources to the terminal through dynamic scheduling (Dynamic Scheduling), or allocate SL CG transmission resources to the terminal. For the resource allocation method of CG, there are mainly two configuration authorization methods: the first type of configuration authorization (type-1 configured grant) and the second type of configuration authorization (type-2 configured grant).

[0130] The first type of configuration authorization refers to the network side equipment configuring the sideline configuration authorization transmission resources for the terminal through Radio Resource Control (RRC) signaling. The RRC signaling configuration includes all transmission resources and transmission parameters including time domain resources, frequency domain resources, demodulation reference signal (DMRS), modulation and coding scheme (MCS), etc. Then, the terminal uses the configured transmission parameters to perform sideline transmission on the configured time and frequency resources.

[0131] The second type of configuration authorization adopts a two-step resource configuration method, namely, RRC+Downlink Control Information (DCI) method. First, RRC signaling configures transmission resources and transmission parameters including the period of time-frequency resources, the number of HARQ processes, etc., and then DCI activates the transmission of the second type of configuration authorization, and simultaneously configures other transmission resources and transmission parameters including time domain resources, frequency domain resources, MCS, etc. After receiving the RRC signaling, the UE cannot immediately use the resources and parameters configured by the high-level parameters for side transmission, but needs to receive the corresponding DCI activation and configure other resources and transmission parameters before it can perform side transmission. In addition, the network-side device can deactivate the configuration transmission through DCI. After the terminal receives the deactivated DCI, the transmission resource can no longer be used for side transmission.

[0132] If the network side device has allocated a configuration authorized transmission resource to the terminal, then when the terminal has sideline data to be transmitted, it can directly use the transmission resource for transmission without sending a Scheduling Request (SR) or Buffer Status Report (BSR) to the network side device to request transmission resources, thereby reducing transmission latency. In the sideline configuration authorization, the network side device allocates periodic transmission resources, and in each period, the network side device can configure multiple transmission resources. Figure 6 is a schematic diagram of configuring transmission resources for network side devices according to related technologies, such as Figure 6 As shown, the transmission resources authorized by the network side device configuration are periodically repeated transmission resources, wherein each cycle includes 4 side row configuration authorized transmission resources.

[0133] In the resource allocation method of mode 1, if the sidelink feedback is activated, the receiving terminal will send feedback information to the sending terminal according to the sidelink data reception status. The sending terminal reports the sidelink feedback information (SL HARQ-ACK / NACK) to the network device. Then, the network device decides whether to allocate retransmission resources based on the SL HARQ-ACK / NACK reported by the sending terminal.

[0134] In the sideline configuration authorization transmission, the network side device can configure the transmission resources of the sideline configuration authorization for the terminal and allocate the physical uplink control channel (Physical Uplink Control Channel, referred to as PUCCH) transmission resources. The terminal can report the sideline feedback information to the network side device on the PUCCH. If the network side device receives the NACK feedback information reported by the terminal, it will allocate retransmission resources through dynamic scheduling, and the HARQ process number needs to be indicated in the dynamically scheduled DCI to indicate the HARQ process to which the retransmission resources allocated to the terminal belong. Therefore, the network side device needs to determine the HARQ process number corresponding to the sideline transmission.

[0135] The technical solution of the embodiment of the present invention can be applied to various communication systems, for example: Global System of Mobile communication (GSM) system, Code Division Multiple Access (CDMA) system, Wideband Code Division Multiple Access (WCDMA) system, General Packet Radio Service (GPRS), Long Term Evolution (LTE) system, LTE Frequency Division Duplex (FDD) system, LTE Time Division Duplex (TDD), Universal Mobile Telecommunication System (UMTS), Worldwide Interoperability for Microwave Access (WiMAX) communication system or 5G system, etc.

[0143] According to one embodiment of the present invention, an embodiment of an information processing method is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0144] In this embodiment, an information processing method running on the above terminal device is provided. Figure 7 is a flow chart of an information processing method according to one embodiment of the present invention. Figure 7 As shown, the method comprises the following steps:

[0145] Step S70, receiving configuration information from a network side device, wherein the configuration information is used to configure a side configuration authorization transmission resource, and the side configuration authorization transmission resource is a transmission resource located in a resource pool;

[0146] Step S71, determining the time domain information corresponding to the sideline configuration authorization transmission resource based on the configuration information;

[0147] Step S72: determining a first hybrid automatic repeat request process number according to the time domain information corresponding to the authorized transmission resource configured in the sideline.

[0148] Through the above steps, it is possible to adopt a method of receiving configuration information from a network side device, where the configuration information is used to configure a side configuration authorization transmission resource and the side configuration authorization transmission resource is a transmission resource located in a resource pool, determine the time domain information corresponding to the side configuration authorization transmission resource through the configuration information, and determine the first hybrid automatic repeat request process number according to the time domain information corresponding to the side configuration authorization transmission resource, thereby achieving the purpose of providing a HARQ process number determination method for the side configuration authorization, thereby effectively filling the technical gap of being unable to determine the HARQ process number in the side configuration authorization, increasing the flexibility and diversity of the HARQ process number determination method, and thus solving the technical problem of the lack of a HARQ process number determination method for the side configuration authorization in the related technology.

[0149] In the above configuration information, both the sideline configuration authorization transmission resource and the PUCCH transmission resource can be configured, wherein the PUCCH transmission resource is the PUCCH resource corresponding to the sideline configuration authorization transmission resource, that is, the sideline feedback information associated with the sideline data transmitted on the sideline configuration authorization transmission resource is reported to the network side device through the PUCCH transmission resource. For the terminal device, the first hybrid automatic repeat request process number can be determined according to the time domain position of the sideline configuration authorization transmission resource.

[0150] The resource pool may be one of multiple resource pools. Figure 8 is a schematic diagram of determining a resource pool according to one optional embodiment of the present invention, such as Figure 8 As shown in FIG. 1 , the resource pool is determined in a system frame number (SFN) or direct frame number (DFN) period in the following manner. Taking the subcarrier spacing of 15kHz as an example, a DFN period includes 10240 subframes (or time slots), corresponding to subframes 0, 1, 2, ..., 10239. Subframes that cannot be used for sideline transmission, such as synchronization subframes, downlink subframes, special subframes (i.e., downlink subframes and special subframes in TDD systems), and reserved subframes, are removed, and the remaining subframes are numbered as follows: The remaining number of subframes can be L bitmap Divisibility, bitmap It is repeated periodically in the remaining subframes, wherein a bit being 1 indicates that the subframe corresponding to the bit in the remaining subframes belongs to the resource pool, otherwise it does not belong to the resource pool.

[0151] A DFN cycle includes 10240 subframes, and the period of the synchronization signal is 160ms. Assuming that there are 2 synchronization subframes in a synchronization cycle, there are 128 synchronization subframes in a DFN cycle, and the length of the bitmap used to indicate the time domain resources of the resource pool is 10 bits. To this end, 2 reserved subframes are required, and the number of remaining subframes is (10240-128-2=10110), which can be divided by the length of the bitmap 10, so that the remaining subframes are renumbered as 0, 1, 2, ..., 10109, and the first 3 bits of the bitmap are 1, and the remaining 7 bits are 0. That is, in the remaining subframes, the first 3 subframes in every 10 subframes belong to the resource pool, and the remaining subframes do not belong to the resource pool. Since the bitmap needs to be repeated 1011 times in the remaining subframes to indicate whether all subframes belong to the resource pool, and each bitmap period includes 3 subframes, there are 3033 subframes belonging to the resource pool in a DFN period. Each time slot index in the resource pool corresponds to a time slot index in the DFN period. For example, time slots 0, 1, 2, 3, 4, and 5 in the resource pool correspond to time slots 0, 2, 4, 13, 14, and 15 in the DFN period. The network configuration side configuration authorized transmission resources will be associated with a resource pool, and the network configuration side configuration authorized transmission resources are transmission resources located in this resource pool.

[0152] In this embodiment, the time domain information corresponding to the sideline configuration authorized transmission resource is the time slot index of the sideline configuration authorized transmission resource in the resource pool. For example, for the above embodiment, the resource pool where the sideline configuration authorized transmission resource is located includes 3033 subframes, so the time domain information corresponding to the sideline configuration authorized transmission resource is the time slot index in the resource pool, that is, the time slot index in the range of [0,3032].

[0153] Optionally, the time domain information corresponding to the sideline configuration authorized transmission resource is a time slot index in a time slot that may be used in the resource pool. For example, for the above embodiment, the time slot set that may be used in the resource pool is the remaining subframe, and its corresponding time slot index range is [0,10109].

[0154] Optionally, at least one of the following parameters may be determined from the above configuration information:

[0155] (1) Sideline configuration of the period of authorized transmission resources;

[0156] (2) The total number of HARQ process numbers corresponding to the currently configured authorization;

[0157] (3) HARQ process number offset, used to determine the first HARQ process number corresponding to the currently configured grant;

[0158] (4) The time slot corresponding to the time domain resource of the sideline configuration authorized transmission resource.

[0159] In one embodiment, the configuration information includes time slot offset indication information and a period parameter, and the sideline configuration authorization transmission resource is determined according to the time slot offset indication information and the period parameter; wherein the time slot offset indication information is used to determine the time domain information of the first sideline configuration authorization transmission resource in a system frame number cycle (or a direct frame number cycle). The time slot offset indication information is represented by the number of time slots, and the number of time slots represents the number of physical time slots or the number of logical time slots, wherein the logical time slot is the time slot in the resource pool associated with the configuration authorization transmission resource or the time slot that may be used for the resource pool. The period parameter is used to determine the period of the sideline configuration authorization transmission resource, and is represented by the number of time slots, and the number of time slots represents the number of physical time slots or the number of logical time slots, wherein the logical time slot is the time slot in the resource pool associated with the configuration authorization transmission resource or the time slot that may be used for the resource pool.

[0160] Optionally, step S72, determining the first hybrid automatic repeat request process number according to the time domain information corresponding to the authorized transmission resource configured on the sideline may include the following execution steps:

[0161] Step S720, determining a period parameter based on the configuration information, wherein the period parameter is a period of sideline configuration authorization transmission resources;

[0162] Step S722: Determine the first hybrid automatic repeat request process number according to the time domain information and period parameters corresponding to the authorized transmission resources configured in the sideline.

[0163] Optionally, the period of the sideline configuration authorized transmission resource is expressed in the number of time slots to describe the number of time slots in the resource pool where the sideline configuration authorized transmission resource is located. Alternatively, the period of the sideline configuration authorized transmission resource is expressed in the number of time slots to describe the number of candidate time slots for the resource pool.

[0164] Optionally, the period of the sideline configuration authorization transmission resource is represented by the number of logical time slots, or the number of physical time slots.

[0165] If the parameter periodicity is expressed in the number of time slots, the corresponding first HARQ process number is determined by the following formula according to the time domain position of the sideline configuration grant transmission resource in the resource pool where the sideline configuration grant is located:

[0166] HARQ Process ID=[floor(CURRENT_slot / periodicity)]mod nrofHARQ-Processes+harq-procID-offset;

[0167] The meanings of the parameters in the formula are as follows:

[0168] (1) CURRENT_slot represents the time slot corresponding to the time domain resource of the sideline configuration authorization transmission resource. The index of this time slot is the time slot index in the resource pool where the sideline configuration authorization is located. The value range of this parameter is [0, N-1], N represents the total number of time slots contained in the current resource pool, and the index of this time slot is the time slot index in the resource pool where the sideline configuration authorization is located.

[0169] (2) periodicity indicates the period of the transmission resource of the sideline configuration grant, which is expressed in time slots; further, it indicates the number of time slots in the resource pool where the sideline configuration grant is located.

[0170] (3)nrofHARQ-Processes indicates the total number of HARQ process numbers corresponding to the sideline configuration authorization.

[0171] (4) harq-procID-offset is used to determine the first HARQ process ID corresponding to the side configuration authorization; optionally, if the network side device does not configure this parameter, the value of this parameter is 0.

[0172] In the above formula, mod represents the modulo operation, and floor represents the rounding down operation.

[0173] Still like Figure 8 As shown, the network side device configures the transmission resources authorized by the side configuration in the resource pool. The three time slots of the period of the side configuration authorization represent the three time slots in the resource pool. The first time slot position of the side configuration authorization is time slot 2. According to the period of the side configuration authorization, time slots 5, 8, 11, etc. will include the transmission resources authorized by the side configuration.

[0174] In the above formula for calculating the HARQ process number, CURRENT_slot represents the time slot where the transmission resource authorized by the side configuration in the resource pool is located, that is, time slot 2, time slot 5, time slot 8, time slot 11, time slot 14, time slot 17...time slot 3032, etc. Periodicity represents the period of the transmission resource authorized by the side configuration, which can be expressed by the number of time slots in the resource pool where the configuration authorization is located, that is, the period is 3 time slots. If the configuration parameters nrofHARQ-Processes=4, harq-procID-offset=0, the HARQ process numbers corresponding to the side configuration authorization are 0, 1, 2, and 3 respectively. In this embodiment, the HARQ process numbers corresponding to the transmission resources authorized by the above side configuration in time domain positions such as time slot 2, time slot 5, time slot 8, time slot 11, time slot 14, and time slot 17 are 0, 1, 2, 3, 0, 1, etc. respectively.

[0175] In the process of determining the first hybrid automatic repeat request process number according to the time domain information corresponding to the sideline configuration authorized transmission resource, the network side device configures the sideline configuration authorized transmission resource for the terminal, and according to the time domain position of the sideline configuration authorized transmission resource on the sideline link, the corresponding first HARQ process number can also be determined by the following formula:

[0176] HARQ Process ID=[floor(CURRENT_slot×10 / (numberOfSlotsPerFrame×periodicity))]mod nrofHARQ-Processes+harq-procID-offset;

[0177] The meanings of the parameters in the formula are as follows:

[0178] (1) numberOfSlotsPerFrame indicates the number of time slots contained in each wireless frame (Frame or Radio Frame);

[0179] (2) periodicity indicates the period of sideline configuration authorization transmission resources, expressed in milliseconds (ms);

[0180] (3)nrofHARQ-Processes indicates the total number of HARQ process numbers corresponding to the current sideline configuration authorization;

[0181] (4) harq-procID-offset is used to determine the first HARQ process ID corresponding to the current side configuration authorization; in an optional embodiment, if the network side device does not configure this parameter, the value of this parameter is 0.

[0182] CURRENT_slot indicates the time slot corresponding to the time domain resource of the sideline configuration authorization transmission resource. The value range of this parameter is [0, N-1], N indicates the total number of time slots contained in the current resource pool, and the index of this time slot is the time slot index in the resource pool where the sideline configuration authorization is located;

[0183] In an optional embodiment, CURRENT_slot=[(DFN×numberOfSlotsPerFrame)+slotnumber in the frame]; wherein, slot number in the frame represents the index of the sideline configuration authorized transmission resource in a radio frame, and its value range is [0,M-1], and M represents the total number of time slots included in a radio frame; DFN represents the direct frame number (Direct Frame Number); numberOfSlotsPerFrame represents the number of time slots contained in each radio frame (Frame or Radio Frame), which is determined by the subcarrier spacing of the sideline carrier where the sideline transmission is located, or by the uplink subcarrier spacing.

[0184] In an optional embodiment, CURRENT_slot=[(SFN×numberOfSlotsPerFrame)+slotnumber in the frame]; wherein, slot number in the frame represents the index of the sideline configuration authorized transmission resource in a radio frame, and its value range is [0,M-1], and M represents the total number of time slots included in a radio frame; SFN represents the system frame number (System Frame Number); numberOfSlotsPerFrame represents the number of time slots contained in each radio frame (Frame or Radio Frame), which is determined by the subcarrier spacing of the sideline carrier where the sideline transmission is located, or by the uplink subcarrier spacing.

[0185] In the above formula, mod represents the modulo operation, and floor represents the rounding down operation.

[0186] Optionally, the above method may further include the following execution steps:

[0187] Step S73: transmitting first sidewalk data on the sidewalk configuration authorized resources, wherein the first sidewalk data corresponds to a first hybrid automatic repeat request process number.

[0188] The HARQ process number corresponding to the sidelink configuration authorized transmission resource determined by the terminal device in the above manner is the first HARQ process number. The terminal device can use the first HARQ process number to transmit the first sidelink data. The first sidelink data may include: PSCCH and PSSCH. In addition, the terminal device may also carry the first HARQ process number in the sidelink control information (Sidelink Control Information, referred to as SCI), that is, the sidelink data transmitted in the PSSCH corresponds to the first HARQ process number.

[0189] Optionally, the above method may further include the following execution steps:

[0190] Step S74, receiving downlink control information from the network side device, wherein the downlink control information is used to schedule downlink transmission resources, and the downlink control information carries a first hybrid automatic repeat request process number;

[0191] Step S75: retransmit the first sidelink data on the sidelink transmission resources scheduled by the downlink control information.

[0192] In the sideline configuration grant transmission, the network side device may configure PUCCH transmission resources for the terminal device. The terminal may report the sideline feedback information to the network side device on the PUCCH transmission resources.

[0193] Optionally, the network side device configures a PUCCH transmission resource in each sideline configuration authorization period. In a sideline configuration authorization period, the terminal sends the first sideline data to the receiving terminal through the sideline configuration authorization transmission resource, corresponding to the first HARQ process number. If the terminal receives the sideline feedback information sent by the receiving terminal as NACK, it will report NACK to the network through the PUCCH in this period. If the network side device receives NACK feedback information reported by the terminal, it will dynamically allocate retransmission resources for the sideline transmission through DCI, and indicate the first HARQ process number in the DCI, so that the terminal device retransmits the first sideline data on the sideline transmission resources scheduled by the downlink control information.

[0194] Optionally, the above method may further include the following execution steps:

[0195] Step S76: based on the mapping relationship between the first hybrid automatic repeat request process number and the second hybrid automatic repeat request process number, transmit the second sideline data on the sideline configuration authorized transmission resources, wherein the second sideline data corresponds to the second hybrid automatic repeat request process number.

[0196] When the terminal uses the sideline configuration authorized transmission resource to transmit sideline data, the first HARQ process number is determined according to the time domain information of the sideline configuration authorized transmission resource. Further, the terminal can predetermine the mapping relationship between the first HARQ process number and the second HARQ process number. Based on the mapping relationship, the terminal device can use the second HARQ process number to transmit the second sideline data on the sideline configuration authorized transmission resource. The second sideline data may include: PSCCH and PSSCH. In addition, the terminal device can also carry the second HARQ process number in the SCI, that is, the sideline data transmitted in the PSSCH corresponds to the second HARQ process number.

[0197] Optionally, the above method may further include the following execution steps:

[0198] Step S77, receiving downlink control information from the network side device, wherein the downlink control information is used to schedule downlink transmission resources, and the downlink control information carries a first hybrid automatic repeat request process number;

[0199] Step S78: retransmit the second sidelink data on the sidelink transmission resources scheduled by the downlink control information.

[0200] The network side device determines through the PUCCH transmission resources that the process number corresponding to the transmission resource authorized by the sideline configuration is the first HARQ process number. When the network side device receives NACK, it dynamically allocates retransmission resources for the sideline transmission through DCI, and indicates the first HARQ process number in the DCI. After receiving the DCI and obtaining the first HARQ process number from the DCI, the terminal device can determine that the retransmission resource is a retransmission scheduling for the sideline transmission of the second HARQ process number based on the mapping relationship between the first HARQ process number and the second HARQ process number.

[0201] It can be seen that the first HARQ process number determined by the terminal device according to the time domain information of the sideline configuration authorized transmission resource may be different from the second HARQ process number used when transmitting data using the sideline configuration authorized transmission resource, and the terminal device can also determine the mapping relationship between the first HARQ process number and the second HARQ process number, thereby enabling the terminal device to have higher flexibility or autonomy in determining the HARQ process number of the sideline transmission.

[0202] In this embodiment, another information processing method running on the above network side device is also provided. Fig. 9 is a flow chart of another information processing method according to one embodiment of the present invention. Fig. 9 As shown, the method comprises the following steps:

[0203] Step S90, determining first configuration information, wherein the first configuration information is used to configure a sideline configuration authorization transmission resource, and the sideline configuration authorization transmission resource is a transmission resource located in a resource pool;

[0204] Step S91, determining the time domain information corresponding to the sideline configuration authorization transmission resource based on the first configuration information;

[0205] Step S92: determining a first hybrid automatic repeat request process number according to the time domain information corresponding to the authorized transmission resource configured in the sideline.

[0206] Through the above steps, a first configuration information is determined and sent to the terminal, wherein the first configuration information is used to configure a side configuration authorization transmission resource and the side configuration authorization transmission resource is a transmission resource located in a resource pool. The time domain information corresponding to the side configuration authorization transmission resource is determined through the first configuration information, and the first hybrid automatic repeat request process number is determined according to the time domain information corresponding to the side configuration authorization transmission resource, thereby achieving the purpose of providing a HARQ process number determination method for the side configuration authorization, thereby effectively filling the technical gap of being unable to determine the HARQ process number in the side configuration authorization, increasing the flexibility and diversity of the HARQ process number determination method, and further solving the technical problem of the lack of a HARQ process number determination method for the side configuration authorization in the related technology.

[0207] In the above-mentioned first configuration information, both the sideline configuration authorization transmission resources and the PUCCH transmission resources can be configured. The transmission resources of the sideline configuration authorization configured by the network side device for the terminal device are periodic, and include at most N_max (N_max=2 or 3) sideline configuration authorization transmission resources in each period, and configure one PUCCH transmission resource in each period. The terminal device uses the sideline configuration authorization transmission resources to transmit sideline data in the period, and uses the PUCCH transmission resources to report sideline feedback information to the network side device. Then, the network side device determines whether it is necessary to allocate retransmission resources for the terminal according to the sideline feedback information.

[0208] For the network side device, first, the PUCCH transmission resources can be determined according to the configuration information; secondly, by receiving the PUCCH on the PUCCH transmission resources and determining the SL CG period corresponding to the PUCCH (that is, the period of the sideline configuration authorization to which the PUCCH belongs) and the sideline configuration authorization transmission resources in the period according to the PUCCH, and then determining the first HARQ process number according to the time domain information of the sideline configuration authorization transmission resources.

[0209] The resource pool may be one of a plurality of resource pools. Figure 8 As shown in FIG. 1 , the resource pool is determined in one SFN or DFN cycle in the following manner. Taking the subcarrier spacing of 15 kHz as an example, one DFN cycle includes 10240 subframes (or time slots), corresponding to subframes 0, 1, 2, ..., 10239. Subframes that cannot be used for sideline transmission, such as synchronization subframes, downlink subframes, special subframes (i.e., downlink subframes and special subframes in TDD systems), and reserved subframes, are removed, and the remaining subframes are numbered as follows: The remaining number of subframes can be L bitmap Divisibility, bitmap It is repeated periodically in the remaining subframes, wherein a bit being 1 indicates that the subframe corresponding to the bit in the remaining subframes belongs to the resource pool, otherwise it does not belong to the resource pool.

[0210] A DFN cycle includes 10240 subframes, and the period of the synchronization signal is 160ms. Assuming that there are 2 synchronization subframes in a synchronization cycle, there are 128 synchronization subframes in a DFN cycle, and the length of the bitmap used to indicate the time domain resources of the resource pool is 10 bits. To this end, 2 reserved subframes are required, and the number of remaining subframes is (10240-128-2=10110), which can be divided by the length of the bitmap 10, so that the remaining subframes are renumbered as 0, 1, 2, ..., 10109, and the first 3 bits of the bitmap are 1, and the remaining 7 bits are 0. That is, in the remaining subframes, the first 3 subframes in every 10 subframes belong to the resource pool, and the remaining subframes do not belong to the resource pool. Since the bitmap needs to be repeated 1011 times in the remaining subframes to indicate whether all subframes belong to the resource pool, and each bitmap period includes 3 subframes, there are 3033 subframes belonging to the resource pool in a DFN period. Each time slot index in the resource pool corresponds to a time slot index in the DFN period. For example, time slots 0, 1, 2, 3, 4, and 5 in the resource pool correspond to time slots 0, 2, 4, 13, 14, and 15 in the DFN period. The network configuration side configuration authorized transmission resources will be associated with a resource pool, and the network configuration side configuration authorized transmission resources are transmission resources located in this resource pool.

[0211] In this embodiment, the time domain information corresponding to the sideline configuration authorized transmission resource is the time slot index of the sideline configuration authorized transmission resource in the resource pool. For example, for the above embodiment, the resource pool where the sideline configuration authorized transmission resource is located includes 3033 subframes, so the time domain information corresponding to the sideline configuration authorized transmission resource is the time slot index in the resource pool, that is, the time slot index in the range of [0,3032].

[0212] Optionally, the time domain information corresponding to the sideline configuration authorized transmission resource is a time slot index in a time slot that may be used in the resource pool. For example, for the above embodiment, the time slot set that may be used in the resource pool is the remaining subframe, and its corresponding time slot index range is [0,10109].

[0213] Optionally, the above method may further include the following execution steps:

[0214] Step S93, sending first configuration information to the terminal, wherein the first configuration information is also used by the terminal to determine the time domain information corresponding to the sideline configuration authorized transmission resource and determine the first hybrid automatic repeat request process number according to the time domain information corresponding to the sideline configuration authorized transmission resource.

[0215] The first hybrid automatic repeat request process number can be determined not only by the network side device according to the first configuration information, but also by the terminal device according to the first configuration information. Therefore, the network side device can send the first configuration information to the terminal device, so that the terminal device determines the time domain information corresponding to the side configuration authorized transmission resource and determines the first hybrid automatic repeat request process number according to the time domain information corresponding to the side configuration authorized transmission resource.

[0216] Optionally, at least one of the following parameters may be determined from the first configuration information:

[0217] (1) Sideline configuration of the period of authorized transmission resources;

[0218] (2) The total number of HARQ process numbers corresponding to the currently configured authorization;

[0219] (3) HARQ process number offset, used to determine the first HARQ process number corresponding to the currently configured grant;

[0220] (4) The time slot corresponding to the time domain resource of the sideline configuration authorized transmission resource.

[0221] In one embodiment, the configuration information includes time slot offset indication information and a period parameter, and the sideline configuration authorization transmission resource is determined according to the time slot offset indication information and the period parameter; wherein the time slot offset indication information is used to determine the time domain information of the first sideline configuration authorization transmission resource in a system frame number cycle (or a direct frame number cycle). The time slot offset indication information is represented by the number of time slots, and the number of time slots represents the number of physical time slots or the number of logical time slots, wherein the logical time slot is the time slot in the resource pool associated with the configuration authorization transmission resource or the candidate time slot for the resource pool. The period parameter is used to determine the period of the sideline configuration authorization transmission resource, and is represented by the number of time slots, and the number of time slots represents the number of physical time slots or the number of logical time slots, wherein the logical time slot is the time slot in the resource pool associated with the configuration authorization transmission resource or the candidate time slot for the resource pool.

[0222] Optionally, in step S92, determining the first hybrid automatic repeat request process number according to the time domain information corresponding to the sideline configuration authorized transmission resource may include the following execution steps:

[0223] Step S920, determining a period parameter based on the first configuration information, wherein the period parameter is a period of sideline configuration authorization transmission resources;

[0224] Step S922: Determine the first hybrid automatic repeat request process number according to the time domain information and period parameters corresponding to the authorized transmission resources configured in the sideline.

[0225] Optionally, the period of the sideline configuration authorized transmission resource is expressed in the number of time slots, which is used to describe the number of time slots in the resource pool where the sideline configuration authorized transmission resource is located. Alternatively, the period of the sideline configuration authorized transmission resource is expressed in the number of time slots, which is used to describe the number of candidate time slots for the resource pool.

[0226] If the parameter periodicity is expressed in the number of time slots, the corresponding first HARQ process number is determined by the following formula according to the time domain position of the sideline configuration grant transmission resource in the resource pool where the sideline configuration grant is located:

[0227] HARQ Process ID=[floor(CURRENT_slot / periodicity)]mod nrofHARQ-Processes+harq-procID-offset;

[0228] The meanings of the parameters in the formula are as follows:

[0229] (1) CURRENT_slot represents the time slot corresponding to the time domain resource of the sideline configuration authorization transmission resource. The index of this time slot is the time slot index in the resource pool where the sideline configuration authorization is located. The value range of this parameter is [0, N-1], N represents the total number of time slots contained in the current resource pool, and the index of this time slot is the time slot index in the resource pool where the sideline configuration authorization is located.

[0230] (2) periodicity indicates the period of the transmission resource of the sideline configuration grant, which is expressed in time slots; further, it indicates the number of time slots in the resource pool where the sideline configuration grant is located.

[0231] (3)nrofHARQ-Processes indicates the total number of HARQ process numbers corresponding to the sideline configuration authorization.

[0232] (4) harq-procID-offset is used to determine the first HARQ process ID corresponding to the side configuration authorization; optionally, if the network side device does not configure this parameter, the value of this parameter is 0.

[0233] In the above formula, mod represents the modulo operation, and floor represents the rounding down operation.

[0234] Still like Figure 8 As shown, the network side device configures the transmission resources authorized by the side configuration in the resource pool. The three time slots of the period of the side configuration authorization represent the three time slots in the resource pool. The first time slot position of the side configuration authorization is time slot 2. According to the period of the side configuration authorization, time slots 5, 8, 11, etc. will include the transmission resources authorized by the side configuration.

[0235] In the above formula for calculating the HARQ process number, CURRENT_slot represents the time slot where the transmission resource authorized by the side configuration in the resource pool is located, that is, time slot 2, time slot 5, time slot 8, time slot 11, time slot 14, time slot 17...time slot 3032, etc. Periodicity represents the period of the transmission resource authorized by the side configuration, which can be expressed by the number of time slots in the resource pool where the configuration authorization is located, that is, the period is 3 time slots. If the configuration parameters nrofHARQ-Processes=4, harq-procID-offset=0, the HARQ process numbers corresponding to the side configuration authorization are 0, 1, 2, and 3 respectively. In this embodiment, the HARQ process numbers corresponding to the transmission resources authorized by the above side configuration in time domain positions such as time slot 2, time slot 5, time slot 8, time slot 11, time slot 14, and time slot 17 are 0, 1, 2, 3, 0, 1, etc. respectively.

[0236] In the process of determining the first hybrid automatic repeat request process number according to the time domain information corresponding to the sideline configuration authorized transmission resource, the network side device configures the sideline configuration authorized transmission resource for the terminal, and according to the time domain position of the sideline configuration authorized transmission resource on the sideline link, the corresponding first HARQ process number can be determined by the following formula:

[0237] HARQ Process ID=[floor(CURRENT_slot×10 / (numberOfSlotsPerFrame×periodicity))]mod nrofHARQ-Processes+harq-procID-offset;

[0238] The meanings of the parameters in the formula are as follows:

[0239] (1) numberOfSlotsPerFrame indicates the number of time slots contained in each wireless frame (Frame or Radio Frame);

[0240] (2) periodicity indicates the period of sideline configuration authorization transmission resources, expressed in milliseconds (ms);

[0241] (3)nrofHARQ-Processes indicates the total number of HARQ process numbers corresponding to the current sideline configuration authorization;

[0242] (4) harq-procID-offset is used to determine the first HARQ process ID corresponding to the current side configuration authorization; in an optional embodiment, if the network side device does not configure this parameter, the value of this parameter is 0.

[0243] CURRENT_slot indicates the time slot corresponding to the time domain resource of the sideline configuration authorization transmission resource. The value range of this parameter is [0, N-1], N indicates the total number of time slots contained in the current resource pool, and the index of this time slot is the time slot index in the resource pool where the sideline configuration authorization is located;

[0244] In an optional embodiment, CURRENT_slot=[(DFN×numberOfSlotsPerFrame)+slotnumber in the frame]; wherein, slot number in the frame represents the index of the sideline configuration authorized transmission resource in a radio frame, and its value range is [0,M-1], and M represents the total number of time slots included in a radio frame; DFN represents the direct frame number (Direct Frame Number); numberOfSlotsPerFrame represents the number of time slots contained in each radio frame (Frame or Radio Frame), which is determined by the subcarrier spacing of the sideline carrier where the sideline transmission is located, or by the uplink subcarrier spacing.

[0245] In an optional embodiment, CURRENT_slot=[(SFN×numberOfSlotsPerFrame)+slotnumber in the frame]; wherein, slot number in the frame represents the index of the sideline configuration authorized transmission resource in a radio frame, and its value range is [0,M-1], and M represents the total number of time slots included in a radio frame; SFN represents the system frame number (System Frame Number); numberOfSlotsPerFrame represents the number of time slots contained in each radio frame (Frame or Radio Frame), which is determined by the subcarrier spacing of the sideline carrier where the sideline transmission is located, or by the uplink subcarrier spacing.

[0246] In the above formula, mod represents the modulo operation, and floor represents the rounding down operation.

[0247] Optionally, in step S91, determining the time domain information corresponding to the sideline configuration authorized transmission resource based on the first configuration information may include the following execution steps:

[0248] Step S910: receiving an uplink control channel sent by a terminal on an uplink transmission resource based on the first configuration information, wherein the uplink transmission resource and the sidelink configuration authorization transmission resource belong to the same sidelink configuration authorization period, and the uplink control channel is used by the terminal to report sidelink feedback information;

[0249] Step S912: Determine the time domain information corresponding to the sidelink configuration authorized transmission resource according to the time domain information of the uplink transmission resource.

[0250] In the process of configuring the sideline configuration authorization, the network side device will also configure the uplink transmission resources for transmitting the PUCCH, so that there will be a corresponding PUCCH transmission resource in each sideline configuration authorization period. The terminal device sends sideline feedback information to the network side device through the PUCCH. After the network side device receives the PUCCH sent by the terminal device on the uplink transmission resource, it can determine the time domain position of the transmission resource of the sideline configuration authorization belonging to the same period as the PUCCH according to the PUCCH, and then determine the HARQ process number corresponding to the sideline configuration authorization transmission resource according to the above formula.

[0251] Optionally, the above method may further include the following execution steps:

[0252] Step S94, determine at least one of the following parameters: a first parameter and a second parameter; wherein the first parameter is used to determine the time interval between the uplink transmission resource and the sidelink feedback channel transmission resource, and the second parameter is used to determine the time interval between the sidelink feedback channel transmission resource and the sidelink configuration authorization transmission resource.

[0253] The time slot resource of PUCCH is the time slot in the SFN cycle, and the time slot of the sideline configuration authorized transmission resource is the time slot in the SFN cycle (or DFN cycle). The time domain information of the transmission resource authorized by the sideline configuration is determined according to the SFN index (or DFN index) and the time slot number in the radio frame. The transmission of PUCCH uses uplink transmission resources, and its time domain position is determined by the SFN and the time slot number in the radio frame. Optionally, the starting time slots of the SFN cycle and the DFN cycle, that is, SFN#0 and DFN#0 are not aligned, and there is a time interval.

[0254] Fig.10 Schematic diagram of the time interval between the SFN cycle and the DFN cycle according to one optional embodiment of the present invention, Fig.10 As shown, the network side device configures the transmission resources and PUCCH resources of the sideline configuration authorization. The period of the sideline configuration authorization is 10ms, corresponding to 4 HARQ process numbers, which are 0, 1, 2, and 3. The subcarrier spacing of the sideline carrier and the uplink carrier is 15kHz, that is, each wireless frame includes 10 time slots. The transmission time of the PUCCH determined according to the configuration information is time T, then time T corresponds to SFN#0, time slot 8 of the sideline configuration authorization transmission resource, but corresponds to DFN#58, time slot 6.

[0255] Optionally, the network side device can obtain the time interval between the transmission time of the sidelink and the transmission time of the uplink, because the network side device receives the PUCCH at time T, and according to the time domain position T of the PUCCH, the time domain position on the sidelink corresponding to the time domain position T of the PUCCH can be determined.

[0256] It should be noted that the sideline configuration authorization transmission resource associated with the PUCCH is the sideline configuration authorization transmission resource in the same sideline configuration authorization period as the PUCCH. The sideline data transmitted on the sideline configuration authorization transmission resource in this period and its corresponding sideline feedback information are reported to the network side device through the PUCCH associated with it, that is, the PUCCH in this period.

[0257] Therefore, the network side device needs to determine the time interval between the uplink transmission resource and the sidelink feedback channel transmission resource, and / or the time interval between the sidelink feedback channel transmission resource and the sidelink configuration grant transmission resource.

[0258] Optionally, in step S912, determining the time domain information corresponding to the sidelink configuration authorized transmission resource according to the time domain information of the uplink transmission resource may include the following execution steps:

[0259] Step S9120: Determine the time domain information corresponding to the sidelink configuration authorized transmission resource according to at least one of the first parameter and the second parameter and the time domain information of the uplink transmission resource.

[0260] In an optional embodiment, the first configuration information is further used to configure at least one of the uplink transmission resource and the first parameter.

[0261] If the network side device receives the PUCCH at time T, it will determine the time domain position corresponding to the PSFCH according to the PUCCH and the physical sidelink feedback channel (PSFCH) transmission resource time interval. Further, the network side device can determine the time domain position of the transmission resource authorized by the sidelink configuration in the period where the PSFCH is located, and then determine the HARQ process number corresponding to the sidelink transmission resource corresponding to the PUCCH.

[0262] For example, the network side device configures the transmission resources authorized by the sideline configuration for the terminal in the resource pool, and configures the PUCCH transmission resources. The resource pool includes PSFCH transmission resources, and the period of PSFCH is 2 time slots, that is, every 2 time slots in the resource pool include a time slot for transmitting PSFCH, and the time interval between the configured PUCCH time domain resources and PSFCH is 3 time slots. Therefore, when the network side device receives PUCCH, it can determine the time slot position of the PSFCH corresponding to the PUCCH according to the time slot position of the PUCCH time domain resources. In an optional example, the time slot position of the PSFCH is the time slot where the last PSFCH in the period of the sideline configuration authorized transmission resources is located. Therefore, the network side device can determine the time slot where the sideline configuration authorized transmission resources in the period where the PSFCH is located according to the time slot of the PSFCH, and then determine the HARQ process number corresponding to the sideline configuration authorized transmission resources.

[0263] Therefore, in the process of determining the HARQ process number according to the sidelink time domain position corresponding to the sidelink configured authorized transmission resource, the network side device can determine the HARQ process number of the sidelink transmission corresponding to the configured PUCCH transmission resource based on the time interval between the sidelink and the uplink.

[0264] Optionally, the above method may further include the following execution steps:

[0265] Step S95, sending second configuration information to the terminal, wherein the second configuration information is used to configure the resource pool;

[0266] Step S96: determine the second parameter according to the second configuration information.

[0267] In addition to sending the above-mentioned first configuration information to the terminal device, the network side device can also send second configuration information for configuring the resource pool to the terminal device, and can also determine the time interval between the side feedback channel transmission resources and the side configuration authorization transmission resources based on the second configuration information.

[0268] Optionally, the above method may further include the following execution steps:

[0269] Step S97, when the uplink control channel carries non-confirmation information, downlink control information is sent to the terminal, wherein the downlink control information is used to schedule sidelink transmission resources, and the downlink control information carries a first hybrid automatic repeat request process number, and the downlink control information is used to schedule the terminal to retransmit the sidelink data corresponding to the first hybrid automatic repeat request process number on the sidelink transmission resources.

[0270] In the sideline configuration authorization transmission, the network side device can configure PUCCH transmission resources for the terminal device. The terminal can report sideline feedback information to the network side device on the PUCCH transmission resource. If the network side device receives NACK feedback information reported by the terminal, it will dynamically allocate retransmission resources for the sideline transmission through DCI, and indicate the first HARQ process number in the DCI, so that the terminal device retransmits the first sideline data on the sideline transmission resources scheduled by the downlink control information. Therefore, when the network side device allocates retransmission resources to the terminal device in a dynamically scheduled manner through DCI, the first HARQ process number is carried in the DCI. Therefore, after receiving the DCI, the terminal device can determine the first HARQ process number corresponding to the retransmission resources scheduled by the DCI.

[0271] Of course, in the sideline configuration authorization transmission, the network side device may not configure PUCCH transmission resources for the terminal device. At this time, the terminal does not need to report the sideline feedback information to the network side device, that is, it does not need to retransmit based on network scheduling. If the sending side terminal receives a NACK on the PSFCH from the receiving side terminal, the sending side terminal can retransmit. However, the sideline transmission of the sending side terminal usually uses the sideline configuration authorization transmission resources allocated by the network side device. At this time, the HARQ process number corresponding to the sideline transmission is determined by the sending side terminal itself, and has nothing to do with the time domain position of the sideline configuration authorization transmission resources.

[0272] In this embodiment, another information processing method running on the above network side device is also provided. Fig.11 is a flowchart of another information processing method according to one embodiment of the present invention. Fig.11 As shown, the method comprises the following steps:

[0273] Step S1100, determining first configuration information, wherein the first configuration information is used to configure uplink transmission resources;

[0274] Step S1101, determining time domain information corresponding to an uplink transmission resource based on first configuration information;

[0275] Step S1102: determining a first hybrid automatic repeat request process number according to time domain information corresponding to the uplink transmission resource.

[0276] and Fig. 9 The information shown is processed differently. Fig.11 The information processing method shown no longer determines the HARQ ID based on the time domain position of the sidelink transmission resource, but determines the HARQ ID based on the time domain position of the uplink transmission resource.

[0277] Optionally, the above method may further include the following execution steps:

[0278] Step S1103, determining a period parameter based on the first configuration information, wherein the first configuration information is also used to configure a sideline configuration authorization transmission resource, the sideline configuration authorization transmission resource is used to transmit sideline data, and the period parameter is used to determine a period of the sideline configuration authorization transmission resource;

[0279] The sidelink configuration authorized transmission resource and the uplink transmission resource are associated, that is, the sidelink data transmitted on the sidelink configuration authorized transmission resource and its corresponding sidelink feedback information are transmitted to the network side device on the uplink transmission resource.

[0280] Step S1104: determine a first hybrid automatic repeat request process number according to the time domain information and period parameters corresponding to the uplink transmission resource.

[0281] In the above-mentioned first configuration information, both the sideline configuration authorization transmission resources and the uplink transmission resources can be configured. The transmission resources of the sideline configuration authorization configured by the network side device for the terminal device are periodic, and include at most N_max (N_max=2 or 3) sideline configuration authorization transmission resources in each period, and configure one PUCCH transmission resource in each period. The terminal device uses the sideline configuration authorization transmission resources to transmit sideline data in the period, and uses the PUCCH transmission resources to report sideline feedback information to the network side device. Then, the network side device determines whether it is necessary to allocate retransmission resources for the terminal based on the sideline feedback information.

[0282] Optionally, the time domain information corresponding to the sideline configuration authorized transmission resource is the time slot index of the sideline configuration authorized transmission resource in the resource pool. The period parameter is represented by the number of time slots, which is the number of time slots in the resource pool or the number of candidate time slots for the resource pool.

[0283] The resource pool may be one of a plurality of resource pools. Figure 8 As shown in FIG. 1 , the resource pool is determined in one SFN or DFN cycle in the following manner. Taking the subcarrier spacing of 15 kHz as an example, one DFN cycle includes 10240 subframes (or time slots), corresponding to subframes 0, 1, 2, ..., 10239. Subframes that cannot be used for sideline transmission, such as synchronization subframes, downlink subframes, special subframes (i.e., downlink subframes and special subframes in TDD systems), and reserved subframes, are removed, and the remaining subframes are numbered as follows: The remaining number of subframes can be L bitmap Divisibility, bitmap It is repeated periodically in the remaining subframes, wherein a bit being 1 indicates that the subframe corresponding to the bit in the remaining subframes belongs to the resource pool, otherwise it does not belong to the resource pool.

[0284] A DFN cycle includes 10240 subframes, and the period of the synchronization signal is 160ms. Assuming that there are 2 synchronization subframes in a synchronization cycle, there are 128 synchronization subframes in a DFN cycle, and the length of the bitmap used to indicate the time domain resources of the resource pool is 10 bits. To this end, 2 reserved subframes are required, and the number of remaining subframes is (10240-128-2=10110), which can be divided by the length of the bitmap 10, so that the remaining subframes are renumbered as 0, 1, 2, ..., 10109, and the first 3 bits of the bitmap are 1, and the remaining 7 bits are 0. That is, in the remaining subframes, the first 3 subframes in every 10 subframes belong to the resource pool, and the remaining subframes do not belong to the resource pool. Since the bitmap needs to be repeated 1011 times in the remaining subframes to indicate whether all subframes belong to the resource pool, and each bitmap period includes 3 subframes, there are 3033 subframes belonging to the resource pool in a DFN period. Each time slot index in the resource pool corresponds to a time slot index in the DFN period. For example, time slots 0, 1, 2, 3, 4, and 5 in the resource pool correspond to time slots 0, 2, 4, 13, 14, and 15 in the DFN period. The network configuration side configuration authorized transmission resources will be associated with a resource pool, and the network configuration side configuration authorized transmission resources are transmission resources located in this resource pool.

[0285] In this embodiment, the time domain information corresponding to the sideline configuration authorized transmission resource is the time slot index of the sideline configuration authorized transmission resource in the resource pool. For example, for the above embodiment, the resource pool where the sideline configuration authorized transmission resource is located includes 3033 subframes, so the time domain information corresponding to the sideline configuration authorized transmission resource is the time slot index in the resource pool, that is, the time slot index in the range of [0,3032].

[0286] Optionally, the time domain information corresponding to the sideline configuration authorized transmission resource is a time slot index in a time slot used in the resource pool. For example, for the above embodiment, the time slot set that may be used in the resource pool is the remaining subframe, and its corresponding time slot index range is [0, 10109].

[0287] Optionally, the above method may further include the following execution steps:

[0288] Step S1105: sending downlink control information to the terminal, wherein the downlink control information is used to schedule sidelink transmission resources, and the downlink control information carries a first hybrid automatic repeat request process number.

[0289] In an optional embodiment, the terminal sends a negative acknowledgment to the network side device on the uplink transmission resource. When the network side device detects the negative acknowledgment on the uplink transmission resource, it sends downlink control information to the terminal, and the downlink control information carries the first HARQ process number. After receiving the downlink control information, the terminal can obtain the first HARQ process number from the downlink control information.

[0290] In the sideline configuration authorization transmission, the network side device can configure PUCCH transmission resources for the terminal device. The terminal can report sideline feedback information to the network side device on the PUCCH transmission resource. If the network side device receives NACK feedback information reported by the terminal, it will dynamically allocate retransmission resources for the sideline transmission through DCI, and indicate the first HARQ process number in the DCI, so that the terminal device retransmits the first sideline data on the sideline transmission resources scheduled by the downlink control information. Therefore, when the network side device allocates retransmission resources to the terminal device in a dynamically scheduled manner through DCI, the first HARQ process number is carried in the DCI. Therefore, after receiving the DCI, the terminal device can determine the first HARQ process number corresponding to the retransmission resources scheduled by the DCI.

[0291] For example, the network side device sends the first configuration information to the terminal, and the first configuration information is used to configure the sideline configuration authorization transmission resource and the uplink transmission resource. The terminal transmits the sideline data on the sideline configuration authorization transmission resource. If the sideline feedback information received by the terminal is NACK, the terminal transmits NACK to the network side device on the uplink transmission resource. Then, the network side device determines the first HARQ process number according to the time domain position of the uplink transmission resource, and schedules the sideline transmission resource for the terminal through DCI, which is used for the terminal to retransmit the sideline data, and carries the first HARQ process number in the DCI. The terminal is responsible for receiving the DCI and can determine that the DCI is the retransmission scheduling of the NACK transmitted on the uplink transmission resource by the network side device according to the first HARQ process number. Further, the terminal can determine that the DCI is the retransmission scheduling of the sideline data transmitted on the sideline configuration authorization transmission resource associated with the uplink transmission resource, so the terminal retransmits the sideline data on the sideline transmission resource scheduled by the DCI.

[0292] Of course, in the sideline configuration authorization transmission, the network side device may not configure PUCCH transmission resources for the terminal device. At this time, the terminal does not need to report the sideline feedback information to the network side device, that is, it does not need to retransmit based on network scheduling. If the sending side terminal receives a NACK on the PSFCH from the receiving side terminal, the sending side terminal can retransmit. However, the sideline transmission of the sending side terminal usually uses the sideline configuration authorization transmission resources allocated by the network side device. At this time, the HARQ process number corresponding to the sideline transmission is determined by the sending side terminal itself, and has nothing to do with the time domain position of the sideline configuration authorization transmission resources.

[0293] In this embodiment, another information processing method running on the above network side device is also provided. Fig.12 is a flowchart of another information processing method according to one embodiment of the present invention. Fig.12 As shown, the method comprises the following steps:

[0294] Step S1200, receiving configuration information from a network side device, wherein the configuration information is used for uplink transmission resources;

[0295] Step S1201, determining time domain information corresponding to uplink transmission resources based on configuration information;

[0296] Step S1202: determine a first hybrid automatic repeat request process number according to time domain information corresponding to the uplink transmission resource.

[0297] and Figure 7 The information shown is processed differently. Fig.12 The information processing method shown no longer determines the HARQ ID based on the time domain position of the sidelink transmission resource, but determines the HARQ ID based on the time domain position of the uplink transmission resource.

[0298] Optionally, the configuration information is also used to configure the sideline configuration authorization transmission resources, and the sideline configuration authorization transmission resources are used to transmit the sideline data.

[0299] In the above configuration information, both the sideline configuration authorization transmission resource and the PUCCH transmission resource can be configured, wherein the PUCCH transmission resource is the PUCCH resource corresponding to the sideline configuration authorization transmission resource, that is, the sideline feedback information associated with the sideline data transmitted on the sideline configuration authorization transmission resource is reported to the network side device through the PUCCH transmission resource. For the terminal device, the first hybrid automatic repeat request process number can be determined according to the time domain position of the uplink transmission resource.

[0300] Optionally, the above method may further include the following execution steps:

[0301] Step S1203, determine at least one of the following parameters: a first parameter and a second parameter; wherein the first parameter is used to determine the time interval between the uplink transmission resource and the sidelink feedback channel transmission resource, and the second parameter is used to determine the time interval between the sidelink feedback channel transmission resource and the sidelink configuration authorization transmission resource.

[0302] The time slot resource of PUCCH is the time slot in the SFN cycle, and the time slot of the sideline configuration authorized transmission resource is the time slot in the SFN cycle (or DFN cycle). The time domain information of the transmission resource authorized by the sideline configuration is determined according to the SFN index (or DFN index) and the time slot number of the transmission resource authorized by the sideline configuration in the radio frame. The transmission of PUCCH uses uplink transmission resources, and its time domain position is determined by the SFN and the time slot number in the radio frame. Optionally, the starting time slots of the SFN cycle and the DFN cycle, that is, SFN#0 and DFN#0 are not aligned, and there is a time interval.

[0303] It should be noted that the sideline configuration authorization transmission resource associated with the PUCCH is the sideline configuration authorization transmission resource in the same sideline configuration authorization period as the PUCCH. The sideline data transmitted on the sideline configuration authorization transmission resource in this period and its corresponding sideline feedback information are reported to the network side device through the PUCCH associated with it, that is, the PUCCH in this period.

[0304] Therefore, the network side device needs to determine the time interval between the uplink transmission resource and the sidelink feedback channel transmission resource, and / or the time interval between the sidelink feedback channel transmission resource and the sidelink configuration grant transmission resource.

[0305] Optionally, the above method may further include the following execution steps:

[0306] Step S1204, determining the time domain information corresponding to the sidelink configuration authorized transmission resource according to at least one parameter of the first parameter and the second parameter and the time domain information corresponding to the uplink transmission resource, and obtaining a corresponding relationship between the uplink transmission resource and the sidelink configuration authorized transmission resource;

[0307] Step S1205: Determine the sidelink configuration authorized transmission resource corresponding to the first hybrid automatic repeat request process number according to the first hybrid automatic repeat request process number and the correspondence between the uplink transmission resource and the sidelink configuration authorized transmission resource.

[0308] If the network side device receives the PUCCH at time T, the first hybrid automatic repeat request process number is determined according to the time domain resources of the PUCCH, and further, the time domain position corresponding to the PSFCH is determined according to the PUCCH and the physical sidelink feedback channel (Physical Sidelink Feedback Channel, referred to as PSFCH) transmission resource time interval. Further, the network side device can determine the time domain position of the transmission resource of the sideline configuration authorization in the period where the PSFCH is located, and then determine the transmission resource of the sideline configuration authorization corresponding to the first HARQ process number.

[0309] For example, the network side device configures the transmission resources authorized by the side configuration for the terminal in the resource pool, and configures the PUCCH transmission resources. The resource pool includes PSFCH transmission resources, and the period of PSFCH is 2 time slots, that is, every 2 time slots in the resource pool include a time slot for transmitting PSFCH, and the time interval between the configured PUCCH time domain resources and PSFCH is 3 time slots. Therefore, when the network side device receives the PUCCH, it can determine the first HARQ process number according to the time slot position of the PUCCH time domain resources. In addition, the network side device determines the time slot position of the PSFCH corresponding to the PUCCH according to the time interval between the PUCCH transmission resources and the PSFCH transmission resources. In an optional example, the time slot position of the PSFCH is the time slot where the last PSFCH in the period of the side configuration authorization transmission resources is located. Therefore, the network side device can determine the time slot where the side configuration authorization transmission resource in the period where the PSFCH is located according to the time slot of the PSFCH, and then determine that the side configuration authorization transmission resource corresponds to the first HARQ process number.

[0310] Therefore, in the process of determining the HARQ process number according to the time domain position of the PUCCH transmission resource, the network side device can determine the HARQ process number corresponding to the configured sidelink configuration authorization transmission resource based on the time interval between the sidelink and the uplink.

[0311] Optionally, the above method may further include the following execution steps:

[0312] Step S1206: Transmit first sidelink data on the sidelink configuration authorized transmission resources, wherein the first sidelink data corresponds to a first hybrid automatic repeat request process number.

[0313] The terminal device may use the first HARQ process number to transmit the first sidelink data. The first sidelink data may include: PSCCH and PSSCH. In addition, the terminal device may also carry the first HARQ process number in the SCI, that is, the sidelink data transmitted in the PSSCH corresponds to the first HARQ process number.

[0314] Optionally, the above method may further include the following execution steps:

[0315] Step S1207, receiving downlink control information sent by the network side device, wherein the downlink control information is used to schedule downlink transmission resources, and the downlink control information carries a first hybrid automatic repeat request process number;

[0316] Step S1208: retransmit the first sidelink data on the sidelink transmission resource.

[0317] In the sideline configuration grant transmission, the network side device may configure PUCCH transmission resources for the terminal device. The terminal may report the sideline feedback information to the network side device on the PUCCH transmission resources.

[0318] Optionally, the network side device configures a PUCCH transmission resource in each sideline configuration authorization period. In a sideline configuration authorization period, the terminal sends the first sideline data to the receiving terminal through the sideline configuration authorization transmission resource, corresponding to the first HARQ process number. If the terminal receives the sideline feedback information sent by the receiving terminal as NACK, it will report NACK to the network through the PUCCH in this period. If the network side device receives the NACK feedback information reported by the terminal, and determines the first HARQ process number according to the time domain position of the PUCCH transmission resource, it will dynamically allocate retransmission resources for the sideline transmission through DCI, and indicate the first HARQ process number in the DCI, so that the terminal device retransmits the first sideline data on the sideline transmission resources scheduled by the downlink control information.

[0319] Optionally, the above method may further include the following execution steps:

[0320] Step S1209: Transmit second sidelink data on the sidelink configuration authorized transmission resources, wherein the second sidelink data corresponds to a second hybrid automatic repeat request process number.

[0321] When the terminal uses the sideline configuration authorized transmission resource to transmit sideline data, the first HARQ process number is determined according to the time domain information of the sideline configuration authorized transmission resource. Further, the terminal can predetermine the mapping relationship between the first HARQ process number and the second HARQ process number. Based on the mapping relationship, the terminal device can use the second HARQ process number to transmit the second sideline data on the sideline configuration authorized transmission resource. The second sideline data may include: PSCCH and PSSCH. In addition, the terminal device can also carry the second HARQ process number in the SCI, that is, the sideline data transmitted in the PSSCH corresponds to the second HARQ process number.

[0322] Optionally, the above method may further include the following execution steps:

[0323] Step S1210: Determine a mapping relationship between a first hybrid automatic repeat request process ID and a second hybrid automatic repeat request process ID.

[0324] Optionally, the above method may further include the following execution steps:

[0325] Step S1211, receiving downlink control information sent by a network side device, wherein the downlink control information is used to schedule downlink transmission resources, and the downlink control information carries a first hybrid automatic repeat request process number;

[0326] Step S1212: retransmit the second sidelink data on the sidelink transmission resource based on the mapping relationship between the first hybrid automatic repeat request process number and the second hybrid automatic repeat request process number.

[0327] The network side device determines the first HARQ process number through the PUCCH transmission resources, and determines that the process number corresponding to the transmission resources authorized by the sideline configuration is the first HARQ process number according to the corresponding relationship between the PUCCH and the sideline configuration authorization transmission resources. When the network side device receives NACK, it dynamically allocates retransmission resources for the sideline transmission through DCI, and indicates the first HARQ process number in the DCI. After receiving the DCI and obtaining the first HARQ process number from the DCI, the terminal device can determine that the retransmission resource is a retransmission scheduling for the sideline transmission of the second HARQ process number according to the mapping relationship between the first HARQ process number and the second HARQ process number.

[0328] It can be seen that the first HARQ process number determined by the terminal device according to the time domain information of the sideline configuration authorized transmission resource may be different from the second HARQ process number used when transmitting data using the sideline configuration authorized transmission resource, and the terminal device can also determine the mapping relationship between the first HARQ process number and the second HARQ process number, thereby enabling the terminal device to have higher flexibility or autonomy in determining the HARQ process number of the sideline transmission.

[0329] This embodiment also provides another information processing method running on the above terminal device.

[0330] The first hybrid automatic repeat request process number is determined according to the following formula:

[0331] HARQ Process ID=[floor(CURRENT_slot / periodicity)]mod nrofHARQ-Processes+harq-procID-offset;

[0332] The meanings of the parameters in the formula are as follows:

[0333] (1) CURRENT_slot indicates the time slot index of the sideline configuration authorized transmission resource. Furthermore, this parameter indicates the time slot index within a radio frame period. The value range of this parameter is [0, N-1]. N indicates the total number of time slots contained in a radio frame period. For example, for a 15kHz subcarrier spacing, a radio frame includes 10 time slots and a radio frame period includes 10240 time slots, so the value range of this parameter is [0, 10239].

[0334] (2) periodicity indicates the period of the sideline configuration authorization transmission resources. Optionally, this parameter is expressed in time length, for example: 100ms, 200ms, 500ms, etc. Optionally, this parameter is expressed in the number of time slots. Further, this parameter is expressed in the number of physical time slots. For example, periodicity = 100 time slots, 200 time slots, etc. In the case of 15kHz subcarrier spacing, a period of 100ms corresponds to 100 time slots. In the case of 30kHz subcarrier spacing, a period of 100ms corresponds to 200 time slots, and so on.

[0335] (3)nrofHARQ-Processes indicates the total number of HARQ process numbers corresponding to the sideline configuration authorization.

[0336] (4) harq-procID-offset is used to determine the first HARQ process ID corresponding to the side configuration grant. Optionally, if the network side device does not configure this parameter, the value of this parameter is 0.

[0337] In the above formula, mod represents the modulo operation, and floor represents the rounding down operation.

[0338] In an optional embodiment, the terminal receives configuration information from a network-side device, and determines the time slot where the sideline configuration authorization transmission resource is located according to the configuration information.

[0339] Optionally, at least one of the following parameters may be determined from the above configuration information:

[0340] (1) Sideline configuration of the period of authorized transmission resources;

[0341] (2) The total number of HARQ process numbers corresponding to the currently configured authorization;

[0342] (3) HARQ process number offset, used to determine the first HARQ process number corresponding to the currently configured grant;

[0343] (4) The time slot corresponding to the time domain resource of the sideline configuration authorized transmission resource.

[0344] In an optional implementation, the configuration information includes time slot offset indication information, time domain resource indication information and cycle parameters. The sideline configuration authorization transmission resource is determined based on the time slot offset indication information, the time domain resource indication information and the cycle parameter. The time slot offset indication information is used to determine the time domain information of the first sideline configuration authorization transmission resource in a system frame number cycle (or a direct frame number cycle). Optionally, the time slot offset indication information is represented by the number of physical time slots. The time domain resource indication information is used to determine the time domain position of the sideline configuration authorization transmission resource configured in a sideline configuration authorization cycle, for example, 1, 2 or 3 values ​​are determined based on the time domain resource indication information, and these values ​​represent the time slot interval of the time domain position of the sideline configuration authorization transmission resource relative to the time domain position determined based on the time slot offset indication information. For example, the two values ​​determined based on the time domain resource indication information are 3 and 7 respectively, and the time domain position determined based on the time slot offset indication information is time slot 1, then the time slots where the sideline configuration authorization transmission resource is located are time slots 4 and 8. The period parameter is used to determine the period of the sideline configuration authorization transmission resources, and is expressed in time length or the number of physical time slots.

[0345] For example, the terminal receives the configuration information sent by the network for configuring the transmission resources for the side configuration authorization. The time slots where the transmission resources for the side configuration authorization are located are determined according to the configuration information: 2, 102, 202, 302, 402, 502, 602, 702, 802, etc. The period of the side configuration authorization is 100 time slots, including 3 HARQ process numbers, and the HARQ process number offset is 0. Therefore, the HARQ process numbers corresponding to the side configuration authorization are 0, 1, and 2. Thus, the HARQ process numbers corresponding to the transmission resources for each side configuration authorization determined according to the above formula. Table 1 shows the correspondence between the side configuration authorization transmission resources and the HARQ process numbers, as shown in Table 1:

[0346] Table 1

[0347]

[0348] Optionally, the above method may further include the following execution steps:

[0349] The terminal transmits first sidelink data on the sidelink configuration authorized resources, wherein the first sidelink data corresponds to a second hybrid automatic repeat request process number.

[0350] Optionally, the second hybrid automatic repeat request process number is the same as the first hybrid automatic repeat request process number;

[0351] Optionally, the second hybrid automatic repeat request process number is different from the first hybrid automatic repeat request process number, and the terminal device determines the correspondence between the first HARQ process number and the second HARQ process number.

[0352] The HARQ process number corresponding to the sidelink configuration authorized transmission resource determined by the terminal device in the above manner is the first HARQ process number. The terminal device can use the second HARQ process number to transmit the first sidelink data. The terminal determines the correspondence between the first HARQ process number and the second HARQ process number. The first sidelink data may include: PSCCH and PSSCH. In addition, the terminal device may also carry the second HARQ process number in the sidelink control information SCI, that is, the sidelink data transmitted in the PSSCH corresponds to the second HARQ process number.

[0353] Optionally, the network side device configures a PUCCH transmission resource in each sideline configuration authorization period. In a sideline configuration authorization period, the terminal sends the first sideline data to the receiving terminal through the sideline configuration authorization transmission resource. If the terminal receives the sideline feedback information sent by the receiving terminal as NACK, it will report NACK to the network side device through the PUCCH in this period. The network side device can determine the time domain position of the corresponding sideline configuration authorization transmission resource based on the transmission resource of the PUCCH, so as to determine the HARQ process number corresponding to the sideline data transmitted on the sideline configuration authorization transmission resource, that is, the first HARQ process number. If the network side device receives the NACK feedback information reported by the terminal, it will dynamically allocate retransmission resources for the sideline transmission through the DCI, and indicate the first HARQ process number in the DCI, so that the terminal device retransmits the first sideline data on the sideline transmission resources scheduled by the downlink control information.

[0354] Optionally, the above method may further include the following execution steps:

[0355] In the first step, the terminal receives a DCI from a network side device, wherein the DCI is used to schedule downlink transmission resources, and the downlink control information carries a first HARQ process number;

[0356] In the second step, the terminal determines that the DCI is used to schedule the first sidelink data according to the first HARQ process number carried in the DCI and the correspondence between the first HARQ process number and the second HARQ process number;

[0357] In the third step, the terminal retransmits the first sidelink data on the sidelink transmission resource scheduled by the DCI.

[0358] In an optional implementation manner, the network side device determines the first HARQ process ID by taking the following steps:

[0359] In the first step, the network side device determines that the sideline feedback information reported by the terminal is received on the PUCCH transmission resource;

[0360] In the second step, the network side device determines at least one of a first parameter and a second parameter. The first parameter is used to determine the time interval between the uplink transmission resource and the sideline feedback channel transmission resource, and the second parameter is used to determine the time interval between the sideline feedback channel transmission resource and the sideline configuration authorization transmission resource.

[0361] In the third step, the network side device determines the time slot of the corresponding sideline transmission resource according to the PUCCH transmission resource and at least one of the first parameter and the second parameter;

[0362] In the fourth step, the network side device determines the first HARQ process number corresponding to the sidelink transmission resource according to the following formula:

[0363] HARQ Process ID=[floor(CURRENT_slot / periodicity)]mod nrofHARQ-Processes+harq-procID-offset;

[0364] The meanings of the parameters in the formula are as follows:

[0365] (1) CURRENT_slot indicates the time slot index of the sideline configuration authorized transmission resource. Furthermore, this parameter indicates the time slot index within a radio frame period. The value range of this parameter is [0, N-1]. N indicates the total number of time slots contained in a radio frame period. For example, for a 15kHz subcarrier spacing, a radio frame includes 10 time slots and a radio frame period includes 10240 time slots, so the value range of this parameter is [0, 10239].

[0366] (2) periodicity indicates the period of the sideline configuration authorization transmission resources. Optionally, this parameter is expressed in time length, for example: 100ms, 200ms, 500ms, etc. Optionally, this parameter is expressed in the number of time slots. Further, this parameter is expressed in the number of physical time slots. For example, periodicity = 100 time slots, 200 time slots, etc. In the case of 15kHz subcarrier spacing, a period of 100ms corresponds to 100 time slots. In the case of 30kHz subcarrier spacing, a period of 100ms corresponds to 200 time slots, and so on.

[0367] (3)nrofHARQ-Processes indicates the total number of HARQ process numbers corresponding to the sideline configuration authorization.

[0368] (4) harq-procID-offset is used to determine the first HARQ process ID corresponding to the side configuration grant. Optionally, if the network side device does not configure this parameter, the value of this parameter is 0.

[0369] In the above formula, mod represents the modulo operation, and floor represents the rounding down operation.

[0370] Fig.13 is a schematic diagram of a terminal device autonomously determining a HARQ process number according to one optional embodiment of the present invention, such as Fig.13 As shown, the network side device configures the side configuration authorization transmission resources, including 2 side configuration authorization transmission resources in each cycle, and the total number of HARQ processes authorized by the side configuration is 4, which are HARQ ID 0, HARQ ID1, HARQ ID2 and HARQ ID3. Optionally, the TX UE uses PSSCH1, PSSCH2, PSSCH3, and PSSCH4 to transmit the initial transmission of HARQ ID 0, HARQ ID1, HARQ ID2, and HARQ ID3 respectively. If the feedback information received by the TX UE is all NACK, PSSCH5, PSSCH6, PSSCH7, and PSSCH8 can continue to be used to transmit the retransmission of HARQ ID 0, HARQ ID1, HARQ ID2, and HARQ ID3 respectively.

[0371] Optionally, the TX UE uses PSSCH1 and PSSCH2 to respectively transmit the initial transmission and retransmission of HARQ ID 0.

If the received feedback information is still NACK, PSSCH3 continues to be used to transmit the retransmission of HARQ ID0; if the received feedback information becomes ACK, PSSCH4 is used to transmit the initial transmission of HARQ ID1 or PSSCH4 is used to transmit the initial transmission of HARQ ID0. At this time, the sidelink data transmitted by PSSCH4 and PSSCH1 correspond to different transmission blocks.
