Description

Technical Field

[0001] The embodiments of the present application relate to the field of communications, and more specifically, to a wireless communication method, a terminal device, and a network device. Background Art

[0002] Device to Device (D2D), Vehicle to Vehicle (V2V), Vehicle to Everything (V2X) and other communication architectures can realize communication between terminals based on Sidelink (SL) technology, which is different from the way communication data is received or sent by base stations in traditional cellular systems. This direct communication method between terminals has higher spectrum efficiency and lower transmission delay.

[0003] The 3rd Generation Partnership Project (3GPP) defines two transmission modes: the first mode and the second mode. In the first mode, the transmission resources of the terminal are allocated by the network device; in the second mode, the terminal selects a resource in the resource pool to transmit data. In the New Radio (NR)-V2X, in order to improve reliability, sideline feedback is introduced. For example, for unicast transmission, the transmitting terminal sends sideline data to the receiving terminal, the receiving terminal sends sideline feedback information to the transmitting terminal, and the transmitting terminal determines whether retransmission is required based on the sideline feedback information of the receiving terminal. When the sideline transmission resource is scheduled by the network device, that is, the first mode mentioned above, the transmitting terminal needs to report the sideline feedback information to the network device, and the network device decides whether to allocate retransmission resources to the terminal based on the sideline feedback information reported by the terminal. Among them, the transmitting terminal can dynamically activate or deactivate the sideline feedback. However, in the first mode, the network device is not sure whether the transmitting terminal has activated or deactivated the side feedback. Therefore, the network device does not consider whether the side feedback is activated when allocating transmission resources to the transmitting terminal device. However, for both the transmitting terminal and the receiving terminal, they need processing time to detect received data or prepare data to be sent, which may cause the transmission resources allocated by the network device to be unreasonable, resulting in the inability to transmit data, thereby reducing the reliability of the communication system.

[0045] The following will describe the technical solutions in the embodiments of the present application in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. For the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0046] Before introducing the technical solution of this application, the relevant concepts of this application are first explained below:

[0047] 1. D2D / V2X

[0048] Device-to-device communication is a sidelink transmission technology based on D2D. It is different from the traditional cellular system where communication data is received or sent by base stations, so it has higher spectrum efficiency and lower transmission latency. The Internet of Vehicles system adopts terminal-to-terminal direct communication, and 3GPP defines two transmission modes: mode 1 and mode 2.

[0049] First mode: Figure 1As shown in the figure, the transmission resources of the terminal are allocated by the network device, and the terminal sends data on the sidelink according to the resources allocated by the network device; the network device can allocate resources for a single transmission to the terminal, or allocate resources for semi-static transmission to the terminal. This is also called Mode 3 in LTE-V2X.

[0050] Second mode: Figure 2 As shown, the terminal selects a resource in the resource pool to transmit data. This is also called Mode 4 in LTE-V2X.

[0051] NR-V2X

[0052] In NR-V2X, autonomous driving needs to be supported, which puts higher requirements on data interaction between vehicles, such as higher throughput, lower latency, higher reliability, larger coverage, more flexible resource allocation, etc.

[0053] In NR-V2X, unicast and multicast transmission modes are introduced. For unicast transmission, there is only one terminal at the receiving end, such as Figure 3 As shown in FIG, UE1 and UE2 perform unicast transmission; for multicast transmission, the receiving end is all terminals in a communication group, or all terminals within a certain transmission distance, such as Figure 4 As shown, UE1, UE2, UE3 and UE4 form a communication group, in which UE1 sends data and other UEs in the group are receiving ends; for the broadcast transmission mode, the receiving end is any terminal around the sending end, such as Figure 5 UE1 is the transmitter, and the other UEs around it, namely UE2-UE6, are all receivers.

[0054] 3. Sideways Feedback

[0055] In NR-V2X, in order to improve reliability, a sidelink feedback channel is introduced. For example, for unicast transmission, the transmitting terminal sends sidelink data to the receiving terminal, including data on the physical sidelink control channel (Physical Sidelink Control Channel, PSCCH) and the physical sidelink shared channel (Physical Sidelink Shared Channel, PSSCH), and the receiving terminal sends sidelink feedback information to the transmitting terminal, and the transmitting terminal determines whether retransmission is required based on the feedback information of the receiving terminal. Among them, the sidelink feedback information is also called hybrid automatic repeat request (Hybrid Automatic Repeat Qequest, HARQ) feedback information. The sidelink feedback information is carried in a sidelink feedback channel, such as a physical sidelink feedback channel (Physical Sidelink Feedback Channel, PSFCH).

[0056] The transmitting terminal can dynamically activate or deactivate the sidelink feedback through the sidelink control information (SCI). If the sidelink feedback is activated, the receiving terminal receives the sidelink data sent by the transmitting terminal, and feeds back an acknowledgement (ACK) or a negative acknowledgement (NACK) to the transmitting terminal according to the detection result. The transmitting terminal decides to send retransmission data or new data according to the feedback information of the receiving terminal. If the sidelink feedback is deactivated, the receiving terminal does not need to send feedback information. The transmitting terminal usually sends data in a blind retransmission manner. For example, the transmitting terminal repeats each sidelink data K times instead of deciding whether to send retransmission data according to the sidelink feedback information. When the sidelink transmission resource is scheduled by the network device, that is, the first mode mentioned above, the transmitting terminal needs to report the sidelink feedback information to the network device, and the network device decides whether to allocate retransmission resources to the terminal according to the ACK or NACK reported by the terminal.

[0057] IV. Resource Definition of Transmission Channel

[0058] In this application, the resources of PSSCH are called sidelink transmission resources. The resources of PSFCH are called sidelink feedback resources. The Physical Uplink Control Channel (PUCCH) or Physical Uplink Shared Channel (PUSCH) is used to transmit the sidelink feedback information sent by the transmitting terminal to the receiving terminal, and the resources of PUCCH or PUSCH are called uplink transmission resources.

[0059] Figure 6 The timing diagram between the transmission channels provided in the embodiment of the present application is as follows: Figure 6As shown, the network device allocates two PSSCH and one PUCCH resources at a time through downlink control information (Downlink Control Information, DCI). Assuming that the time for the receiving terminal to process the PSSCH and prepare the side feedback information to be transmitted through the PSFCH is a, the time interval between the starting position of the first symbol of the PSFCH corresponding to the PSSCH and the end position of the last time domain symbol occupied by the PSSCH cannot be less than a, that is, the time interval must be greater than or equal to a, or, the starting position of the first symbol of the PSFCH corresponding to the PSSCH cannot be earlier than the end position of the last time domain symbol occupied by the PSSCH plus the time interval a; the transmitting terminal receives the PSFCH, if the PSFCH carries NACK, the transmitting terminal needs to prepare to retransmit the PSSCH, and the time interval between the time of retransmitting the PSSCH and receiving and processing the PSFCH cannot be less than b, where b at least includes the time for the transmitting end to detect the PSFCH, prepare the time for retransmitting the PSSCH, and the time for transmitting and receiving conversion, for example: Figure 6 As shown, the time interval between the end position of the last time domain symbol occupied by PSFCH and the start position of the first symbol of the next PSSCH must be greater than or equal to b, or the start position of the first symbol for retransmitting PSSCH next time cannot be earlier than the end position of the last time domain symbol of PSFCH corresponding to the previous PSSCH plus the time interval b. The figure shows the case equal to b; the time interval for the transmitting terminal to receive PSFCH and prepare to report the side feedback information to the network through PUCCH (or PUSCH) is c, that is, the interval between the end position of the last time domain symbol occupied by PSFCH and the start position of the first symbol of PUCCH cannot be less than c, or the start position of the first symbol of PUCCH cannot be earlier than the end position of the last time domain symbol occupied by the last PSFCH corresponding to the PSSCH assigned by the network plus the time interval c. Figure 6 The case where the interval between the end position of the last time domain symbol occupied by the PSFCH and the start position of the first symbol of the PUCCH is equal to c is given in the second mode, that is, the case where the terminal device autonomously selects resources, when the side feedback is activated, when the terminal selects the transmission resource, the minimum time interval between two adjacent PSSCHs should be Z = a + b, for example: Figure 6 As shown, the time interval between two adjacent PSSCHs is a+b.

[0060] When the side feedback is deactivated, that is, the receiving terminal does not need to perform side feedback, the transmitting terminal can use blind retransmission, and at this time, two adjacent PSSCH transmission resources can be adjacent time slots.

[0061] In the second mode, the terminal device can select resources autonomously, but as mentioned above, in the first mode, the network device does not determine whether the transmitting terminal has activated or deactivated the side feedback. Therefore, when the network device allocates transmission resources to the transmitting terminal device, it does not consider whether the side feedback is activated. However, for both the transmitting terminal and the receiving terminal, they need processing time to detect the received data or prepare the data to be sent, which may cause the transmission resources allocated by the network device to be unreasonable. For example: Assume that according to the transmission resource configuration of the network device, the time interval of the adjacent PSSCH resources configured by the network device is less than the above a+b, which causes the data to be unable to be transmitted, thereby reducing the reliability of the communication system.

[0062] In order to solve this technical problem, the present application determines whether to activate the side feedback according to the time interval between the transmission resources allocated by the network device. Alternatively, the terminal device can use part of the transmission resources allocated by the network for side transmission and activate the side feedback, or the terminal device can indicate to the network device whether to activate or deactivate the side feedback so that the network device allocates transmission resources, or the network device indicates to the terminal device whether to activate or deactivate the side feedback, in which case the network device can know whether the side feedback is activated, and based on this, the transmission resources can be allocated.

[0063] It should be understood that the terminal device in the embodiment of the present application may also be referred to as user equipment (UE), access terminal, user unit, user station, mobile station, mobile station, remote station, remote terminal, mobile device, user terminal, wireless communication device, terminal, user agent or user device, etc. The terminal device may be a station (STAION, ST) in a WLAN, a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA) device, a handheld device with wireless communication function, a computing device or other processing device connected to a wireless modem, a vehicle-mounted device, a wearable device, and a next-generation communication system, for example, a terminal in an NR network or a terminal in a future evolved Public Land Mobile Network (PLMN) network, etc.

[0064] As an example but not limitation, in the embodiments of the present application, the terminal device may also be a wearable device. Wearable devices may also be referred to as wearable smart devices, which are a general term for wearable devices that are intelligently designed and developed using wearable technology for daily wear, such as glasses, gloves, watches, clothing, and shoes.

[0069] The technical solution of this application will be described in detail below:

[0070] It should be noted that the terminal device referred to in the following embodiments is a transmitting terminal device, which will not be described in detail below.

[0071] Example 1

[0072] Figure 7 An interactive flow chart of a wireless communication method provided in an embodiment of the present application, such as Figure 7 As shown, the method includes:

[0073] Step S710: The network device sends configuration information to the terminal device, where the configuration information is used to configure multiple transmission resources for the terminal device.

[0074] Step S720: The terminal device determines whether to activate side feedback according to the time interval between multiple transmission resources.

[0075] Optionally, the configuration information is used to configure multiple side transmission resources for the terminal device.

[0076] Optionally, the configuration information is used to configure multiple sidelink transmission resources and one uplink transmission resource for the terminal device.

[0077] Optionally, the configuration information is used to configure a sidelink transmission resource and an uplink transmission resource for the terminal device.

[0078] For the configuration information of different functions, step S720 has different optional methods, but is not limited thereto, and is specifically as follows:

[0079] Option 1: The configuration information is used to configure multiple side transmission resources for the terminal device. If the time interval between at least one group of two adjacent side transmission resources among the multiple side transmission resources is less than a first threshold, the terminal device deactivates the side feedback.

[0080] Optional method two: Configuration information is used to configure multiple side transmission resources for the terminal device. If there is at least one group of two adjacent side transmission resources in the multiple side transmission resources that meets the first condition, the terminal device deactivates the side feedback. Among them, for any group of two adjacent side transmission resources in at least one group of two adjacent side transmission resources, the two adjacent side transmission resources meet the first condition including: the starting position of the second side transmission resource in the two adjacent side transmission resources is located before the end position of the side feedback resource corresponding to the first side transmission resource in the two adjacent side transmission resources plus the second threshold. It should be understood that the first side transmission resource is the side transmission resource with the front time domain position in the two adjacent side transmission resources, and the second side transmission resource is the side transmission resource with the rear time domain position in the two adjacent side transmission resources.

[0081] Option three: The configuration information is used to configure multiple side transmission resources and one uplink transmission resource for the terminal device. If the time interval between at least one group of two adjacent side transmission resources among the multiple side transmission resources is less than the first threshold, and / or the time interval between the last side feedback resource corresponding to the multiple side transmission resources and the uplink transmission resource is less than the third threshold, the terminal device deactivates the side feedback.

[0082] Option 4: The configuration information is used to configure multiple side transmission resources and one uplink transmission resource for the terminal device. If there is at least one group of two adjacent side transmission resources in the multiple side transmission resources that meets the above-mentioned first condition, and / or the time interval between the last side feedback resource corresponding to the multiple side transmission resources and the uplink transmission resource is less than a third threshold, the terminal device deactivates the side feedback.

[0083] Option 5: The configuration information is used to configure a sidelink transmission resource and an uplink transmission resource for the terminal device. The sidelink transmission resource is a resource used to transmit the PSSCH. If the time interval between the sidelink feedback resource and the uplink transmission resource corresponding to a sidelink transmission resource is less than a third threshold, the terminal device deactivates the sidelink feedback, and the sidelink feedback resource is a resource used to transmit the PSFCH.

[0084] Optionally, the first threshold is determined according to a first time interval and a second time interval, wherein the first time interval is determined according to a time interval between a first side transmission resource of two adjacent side transmission resources and a side feedback resource corresponding to the first side transmission resource. For example, the first time interval may be Figure 6 The first time interval is determined according to the periodic parameter of the sideline feedback resource configured by the network. The second time interval is determined according to at least one of the following times: the time when the terminal device processes the PSFCH, the time when the terminal device prepares to retransmit the PSSCH, and the time when the transmission and reception are switched. For example, the second time interval can be Figure 6 Corresponding to parameter b in the solution.

[0085] Optionally, the first threshold is the sum of the first time interval and the second time interval. For example, the first threshold may be Figure 6 Corresponding to a+b in the solution.

[0086] Optionally, the first threshold is the sum of the first time interval, the second time interval and the time length occupied by the PSFCH channel. For example, the first threshold can be Figure 6 The time length occupied by the a+b+PSFCH channel in the corresponding solution. Optionally, the time length occupied by the PSFCH channel is the time length corresponding to 1 time domain symbol or 2 time domain symbols.

[0087] Optionally, the first threshold is pre-configured, network configured, or pre-defined by a protocol, but is not limited thereto.

[0088] Optionally, the first threshold is determined by the terminal device. For example, the terminal device determines the position of the PSFCH corresponding to the side transmission resource allocated by the network device according to the time domain position thereof, thereby determining the first time interval; further, the terminal device can determine the first threshold according to the second time interval predefined by the protocol, for example, the first threshold is the sum of the first time interval and the second time interval.

[0089] Optionally, the time interval between the two transmission resources described in the present application may be the time interval between the end position of the first transmission resource and the start position of the second transmission resource of the two transmission resources, for example: the first time interval is the time interval between the end position of the first side transmission resource and the start position of the side feedback resource corresponding to the first side transmission resource. Of course, the time interval between the two transmission resources may be the time interval between the end position of the first transmission resource and the end position of the second transmission resource of the two transmission resources, or the time interval between the two transmission resources may be the time interval between the start position of the first transmission resource and the start position of the second transmission resource of the two transmission resources, and the present application does not limit this.

[0090] It should be understood that the end position in the present application can be described as the end position of the time domain symbol, and the start position can be described as the start position of the time domain symbol, for example: the end position of the first side transmission resource is the end position of the last time domain symbol of the first side transmission resource. The start position of the side feedback resource corresponding to the first side transmission resource is the start position of the first time domain symbol of the side feedback resource corresponding to the first side transmission resource.

[0091] Optionally, the second threshold is pre-configured, network configured, or pre-defined by a protocol, but is not limited thereto. Figure 6 Taking the illustrated solution as an example, the second threshold may be parameter b.

[0092] Optionally, the second threshold is determined based on at least one of the following times: the time when the terminal device processes the PSFCH, the time when the terminal device prepares to retransmit the PSSCH, and the transceiver conversion time. That is, the second threshold is related to the capability of the terminal device.

[0093] Optionally, the third threshold is pre-configured, network configured, or pre-defined by a protocol, but is not limited thereto. Figure 6 Taking the illustrated solution as an example, the third threshold may be parameter c.

[0094] Optionally, the third threshold is determined based on at least one of the following times: the time for the terminal device to process PSFCH, and the time for preparing to report sideline feedback information to the network via PUCCH (or PUSCH), that is, the third threshold is related to the capability of the terminal device.

[0095] The following example illustrates the solution:

[0096] Figure 8 A resource distribution diagram provided in an embodiment of the present application is shown in FIG. Figure 8 As shown, for example, according to the configuration of the network device, the PSSCH sent on time slots 2 / 3 / 4 / 5, and its corresponding PSFCH are all sent on time slot 7, and the PSSCH sent on time slots 6 / 7 / 8 / 9, and its corresponding PSFCH are all sent on time slot 11. Assuming that a time slot includes 14 time domain symbols, namely symbol 0 to symbol 13, if a time slot does not include PSFCH transmission resources, the time domain symbols occupied by PSSCH are symbol 0 to symbol 12, and the last time domain symbol (i.e. symbol 13) in the time slot is a guard period (GP) symbol, and PSSCH data is not mapped on this symbol; if a time slot includes PSFCH transmission resources, the time domain symbols occupied by PSSCH are symbol 0 to symbol 9, and the time domain symbols occupied by the PSFCH channel are symbol 11 and symbol 12, and symbol 10 and symbol 13 in the time slot are GP symbols. Assume that the network device allocates 3 PSSCH resources to the terminal device, which are located in time slots 2, 4, and 6 respectively. Assume that the second time interval b is 1 time slot, then b = 14 time domain symbols. Figure 8 The PSSCH in time slot 2 has the corresponding PSFCH in time slot 7. The first time domain symbol of PSSCH in time slot 2 is symbol 0, and the last time domain symbol is symbol 12. The first time domain symbol of PSFCH in time slot 7 is time domain symbol 11. Therefore, the first time interval a=1+4*14+12=69 time domain symbols. And b=14 time domain symbols. The time interval between time slot 2 and time slot 4 is two time slots, that is, 28 time domain symbols, 28<69+14, at this time the terminal should deactivate the side feedback. If the terminal wants to activate the side feedback, the PSSCH sent in time slot 2 can only receive the corresponding side feedback in time slot 7. At this time, the PSSCH on time slots 4 and 6 cannot be used. Or, from another perspective, Figure 8 As shown, if the terminal device uses time slot 2 to send side data and activates side feedback, the corresponding PSFCH is located in time slot 7, and the resources allocated by the network device for retransmission are located in time slot 4 and time slot 6, both of which are earlier than the time of PSFCH. Therefore, the resources of time slot 4 and time slot 6 allocated by the network device cannot be used.

[0097] It should be understood that in the above embodiment, the terminal device determines whether to activate the side feedback according to the time interval between multiple transmission resources, which may be that the terminal determines the time interval between the multiple transmission resources according to the multiple transmission resources allocated by the network, or the terminal determines the time interval according to one or more transmission resources among the multiple transmission resources allocated by the network. For example, the network allocates 2 side transmission resources and 1 uplink transmission resource, and the terminal may determine the time interval according to the 2 side transmission resources, or may determine the time interval according to the side feedback resource corresponding to the first side transmission resource and the second side transmission resource, or may determine the time interval according to the second side transmission resource and the uplink transmission resource, or may determine the time interval according to the side feedback resource corresponding to the second side transmission resource and the uplink transmission resource.

[0098] In summary, in the present application, in the first mode, the terminal device determines whether to activate side feedback based on the time interval between multiple transmission resources, that is, the side feedback can be activated only when the time interval between multiple transmission resources meets the time conditions such as the terminal device's receiving processing and preparing to send, otherwise, the side feedback is deactivated, thereby ensuring the normal transmission of data and further improving the reliability of the communication system.

[0099] Example 2

[0100] Fig. 9 An interactive flow chart of another wireless communication method provided in an embodiment of the present application, such as Fig. 9 As shown, the method includes:

[0101] Step S910: The network device sends configuration information to the terminal device, where the configuration information is used to configure multiple transmission resources for the terminal device, and the multiple transmission resources include: multiple side transmission resources.

[0102] Step S920: The terminal device determines whether to perform sideline transmission on some of the sideline transmission resources among the multiple sideline transmission resources according to the time interval between the multiple transmission resources.

[0103] Optionally, step S920 includes the following optional methods, but is not limited thereto:

[0104] Option method 1: If there is at least one group of adjacent side transmission resources among the multiple side transmission resources whose time interval is less than a first threshold, the terminal device determines to perform side transmission on some of the multiple side transmission resources.

[0105] Option 2: If there is at least one group of two adjacent side transmission resources among the multiple side transmission resources that meet the first condition, the terminal device determines to perform side transmission on some of the side transmission resources among the multiple side transmission resources. Among them, for any group of two adjacent side transmission resources among the at least one group of two adjacent side transmission resources, the two adjacent side transmission resources meet the first condition including: the starting position of the second side transmission resource among the two adjacent side transmission resources is located before the end position of the side feedback resource corresponding to the first side transmission resource among the two adjacent side transmission resources plus the second threshold. It should be understood that the first side transmission resource is the side transmission resource with the front time domain position among the two adjacent side transmission resources, and the second side transmission resource is the side transmission resource with the rear time domain position among the two adjacent side transmission resources.

[0106] Option three, the multiple transmission resources also include: an uplink transmission resource. If there is at least one group of adjacent side transmission resources in the multiple side transmission resources, the time interval between which is less than the first threshold, and / or the time interval between the last side transmission feedback resource corresponding to the multiple side transmission resources and the uplink transmission resource is less than the third threshold, the terminal device determines to perform side transmission on some of the side transmission resources in the multiple side transmission resources.

[0107] Option 4: The multiple transmission resources further include: an uplink transmission resource. If there is at least one group of two adjacent side transmission resources in the multiple side transmission resources that meet the first condition above, and / or the time interval between the last side transmission feedback resource corresponding to the multiple side transmission resources and the uplink transmission resource is less than a third threshold, the terminal device determines to perform side transmission on some of the side transmission resources in the multiple side transmission resources.

[0108] It should be understood that the concepts involved in the above four optional methods can refer to the explanation of these concepts in Example 1, and this application will not repeat them again.

[0109] Optionally, the part of the side transmission resources is any side transmission resource among a plurality of side transmission resources. Figure 8 As shown, the part of the sideline transmission resources can be the resources of the PSSCH on time slot 2, 4 or 6.

[0110] Optionally, part of the side transmission resources are at least two side transmission resources among the multiple side transmission resources, and the time interval between any two adjacent side transmission resources among the at least two side transmission resources is greater than or equal to the first threshold, and / or, the time interval between the last side feedback resource and the uplink transmission resource corresponding to the at least two side transmission resources is greater than or equal to the third threshold. For example: Assume that according to the configuration of the network device, it is determined that the PSSCH sent on time slots 2 / 3 / 4 / 5, and its corresponding PSFCH are all sent on time slot 7, the PSSCH sent on time slots 6 / 7 / 8 / 9, and its corresponding PSFCH are all sent on time slot 11, and the PSSCH sent on time slots 10 / 11 / 12 / 13, and its corresponding PSFCH are all sent on time slot 15. Assume that a time slot includes 14 time domain symbols, namely symbol 0 to symbol 13. If a time slot does not include PSFCH transmission resources, the time domain symbols occupied by PSSCH are symbol 0 to symbol 12, and the last time domain symbol in the time slot (i.e. symbol 13) is a GP symbol, on which PSSCH data is not mapped; if a time slot includes PSFCH transmission resources, the time domain symbols occupied by PSSCH are symbol 0 to symbol 9, and the time domain symbols occupied by PSFCH channel are symbol 11 and symbol 12, and symbol 10 and symbol 13 in the time slot are GP symbols. Assume that the network device allocates 3 PSSCH resources to the terminal device, which are located in time slots 2, 6, and 10 respectively. Assume that the above-mentioned second time interval, i.e. b, is 1 time slot, then b = 14 time domain symbols. The PSSCH of time slot 2 has a corresponding PSFCH in time slot 7. The first time domain symbol of PSSCH in time slot 2 is symbol 0, the last time domain symbol is symbol 12, and the first time domain symbol of PSFCH in time slot 7 is time domain symbol 11. Therefore, the first time interval a=1+4*14+12=69 time domain symbols. The time interval between the end position of PSSCH in time slot 2 and the start position of PSSCH in time slot 10 is 1+7*14=99 time domain symbols, 99>69+14. At this time, PSSCH in time slot 2 and time slot 10 can be used as the above-mentioned partial side transmission resources. Or, from another perspective, if the terminal device uses time slot 2 to send side data and activates side feedback, its corresponding PSFCH is located in time slot 7, and the resources allocated by the network device for retransmission are located in time slot 10, which is later than the moment of PSFCH. Therefore, the network device can transmit data in the resources of time slot 2 and time slot 10.

[0111] Optionally, if the terminal device determines to perform sideline transmission on part of the sideline transmission resources among the multiple sideline transmission resources, the terminal device activates sideline feedback.

[0112] In summary, in the present application, in the first mode, the terminal device determines whether to perform side transmission on some of the multiple side transmission resources based on the time interval between the multiple transmission resources, that is, when the time interval between the multiple transmission resources does not meet the time conditions such as the terminal device's receiving and processing, and preparing to send, side transmission can be performed on some of the multiple side transmission resources, thereby ensuring the normal transmission of data and further improving the reliability of the communication system.
