Abstract
Description
Communication methods, communication equipment, communication systems, storage media and software products Technical Field
[0001] This disclosure relates to the field of communication technology, and in particular to a communication method, communication device, communication system, storage medium, and program product. Background Technology
[0002] Random Access (RA) can be a 4-step random access (4-STEP RA) method, involving messages 1 (Msg 1), 2, 3, and 4. Msg 1 is the message sent by the terminal to the network device in the first step. Msg 2 is the message sent by the network device to the terminal in the second step. Msg 3 is the message sent by the terminal to the network device in the third step. Msg 4 is the message sent by the network device to the terminal in the fourth step. For example, after sending a random access preamble (MSG1) to the network device, the terminal listens on the Physical Downlink Control Channel (PDCCH) to receive a Random Access Response (RAR) message (MSG2). The RAR listening window begins after a certain time interval following the preamble transmission; this time interval is the round-trip time (RTT) between the terminal and the network device. Similarly, after sending MSG3 to the network device, the terminal needs to listen for MSG4 to resolve potential random access contention. The contention resolution timer starts after a certain interval following the MSG3 transmission.

[0022] This disclosure provides a communication method, communication device, communication system, storage medium, and program product.
[0023] In a first aspect, embodiments of this disclosure propose a communication method executed by a sending end. The method includes: determining multiple sending opportunities corresponding to a data packet, wherein each sending opportunity is used to send the data packet once; after the data packet is sent at the first sending opportunity, starting a first timer after an interval of a first duration, wherein the duration of the first timer is longer than a second duration, the second duration being configured by a receiving end; and during the operation of the first timer, listening for response messages from the receiving end to the data packet.
[0024] The above embodiments can improve the data packet transmission success rate. In the above embodiments, the sending end determines multiple sending opportunities corresponding to a data packet, and each sending opportunity is used to send a data packet once. When the data packet is sent in the first sending opportunity, a first timer is started after a first time interval, and during the operation of the first timer, the sending end listens for response messages to the data packet sent by the receiving end. Since the data packet is sent multiple times, the uplink collision probability of contention channel can be reduced, thereby improving the data packet transmission success rate. The method of starting the first timer after a first time interval when the data packet is sent in the first sending opportunity, and listening for response messages to the data packet sent by the receiving end during the operation of the first timer, solves the problem that in scenarios where data packets are sent multiple times, the sending end does not know which data packet the receiving end will receive (i.e., does not know which data packet the receiving end will respond to), and therefore does not know when to listen for response messages. Furthermore, since the runtime of the first timer is longer than the second time interval configured by the receiving end, the sending end can listen for response messages from the receiving end for any of the first or second data packets sent, which increases the success rate of the sending end listening for response messages.
[0025] In conjunction with some embodiments of the first aspect, in some embodiments, the method further includes: determining the runtime of the first timer based on the sum of the second duration and the third duration, wherein the third duration is the time interval between the end time of the first transmission opportunity and the end time of the last transmission opportunity.
[0026] In the above embodiments, the runtime of the first timer is specified to be how much longer than the second timer. By determining the runtime of the first timer as the sum of the second and third times, it can be ensured that the sending end can listen to the response message of the receiving end to any of the data packets sent on the first or second time, while avoiding resource waste caused by listening to the response message for a long time.
[0027] In conjunction with some embodiments of the first aspect, in some embodiments, a transmission timing corresponds to a transmission resource, and a transmission resource is associated with a temporary identifier of the transmitting end.
[0028] In the above embodiments, since a sending time corresponds to a temporary identifier of the sending end, the network device can determine from the temporary identifier which number the received data packet was sent by the sending end.
[0029] In conjunction with some embodiments of the first aspect, in some embodiments, the step of listening to the response message of the receiving end to the data packet during the operation of the first timer includes: listening to the response message of the receiving end to the data packet according to at least one of a plurality of temporary identifiers corresponding to the plurality of sending times during the operation of the first timer.
[0030] In the above embodiments, during the operation of the first timer, the receiver's response message to the data packet is monitored based on at least one of the multiple temporary identifiers corresponding to multiple sending times, which can improve the success rate of the sender monitoring the response message.
[0031] In conjunction with some embodiments of the first aspect, in some embodiments, the step of listening to the receiver's response message to the data packet according to at least one of the multiple temporary identifiers corresponding to the multiple transmission opportunities during the operation of the first timer includes: listening to the receiver's response message to the data packet according to the N temporary identifiers corresponding to the previous N transmission opportunities during the Nth time period of the operation of the first timer, where N is an integer greater than 0; wherein, the duration of the Nth time period is the time interval between the Nth transmission opportunity and the (N+1)th transmission opportunity.
[0032] In the above embodiments, it is possible to ensure that the sending end can listen to the response message, while minimizing the processing complexity of the sending end and reducing the resource consumption of the sending end in listening to the response message.
[0033] In conjunction with some embodiments of the first aspect, in some embodiments, the method further includes: determining the duration between the end time of the Nth transmission opportunity and the end time of the (N+1)th transmission opportunity as the duration of the Nth time period.
[0034] In the above embodiments, by determining the duration between the end time of the Nth transmission opportunity and the end time of the (N+1)th transmission opportunity as the duration of the Nth time period during the operation of the first timer, the precise division of the time period during the operation of the first timer is achieved.
[0035] In conjunction with some embodiments of the first aspect, the first duration is determined based on the time it takes for data or a message to travel back and forth between the sending end and the receiving end once.
[0036] In the above embodiments, the method for determining the first duration is specified.
[0037] In a second aspect, embodiments of this disclosure provide a communication device, which includes at least one of a transceiver module and a processing module; wherein the communication device is used to execute an optional implementation of the first aspect.
[0038] Thirdly, embodiments of this disclosure provide a communication device, which includes one or more processors; wherein the communication device is used to execute an optional implementation of the first aspect.

[0074] In some embodiments, the network device is a core network device. Optionally, the core network device can be a single device, including a first network element, a second network element, etc., or it can be multiple devices or a group of devices, each including all or part of the first network element, the second network element, etc. Network elements can be virtual or physical.

The processes and information interactions between these internal interfaces can be implemented by software or programs.
[0076] In some embodiments, the access network device may be composed of a central unit (CU) and a distributed unit (DU). The CU may also be called a control unit. The CU-DU structure can separate the protocol layer of the access network device. Some of the protocol layer functions are centrally controlled by the CU, while the remaining part or all of the protocol layer functions are distributed in the DU and centrally controlled by the CU. However, this is not the only possibility.
[0077] It is understood that the communication system described in this disclosure is for the purpose of more clearly illustrating the technical solutions of this disclosure, and does not constitute a limitation on the technical solutions proposed in this disclosure.

[0078] The following embodiments of this disclosure can be applied to the communication system 100 shown in FIG1, or to some of the main bodies, but are not limited thereto. The main bodies shown in FIG1 are illustrative. The communication system may include all or some of the main bodies in FIG1, or may include other main bodies outside of FIG1. The number and form of each main body are arbitrary. Each main body may be physical or virtual. The connection relationship between the main bodies is illustrative. The main bodies may not be connected or may be connected. The connection can be in any way, it can be a direct connection or an indirect connection, it can be a wired connection or a wireless connection.
[0079] The embodiments disclosed herein can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), Future Radio Access (FRA), New-Radio Access Technology (RAT), New Radio (NR), New radio access (NX), Future generation radio access (FX), Global System for Mobile communications (GSM), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), and IEEE 802.20, Ultra-Wideband (UWB), Bluetooth (a registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X) systems, systems utilizing other communication methods, and next-generation systems built upon them, etc. Furthermore, multiple systems can be combined (e.g., a combination of LTE or LTE-A with 5G).
[0080] In some embodiments, diversity slotted ALOHA (DSA) is a technique to reduce the uplink collision probability in contention channels and thus improve uplink capacity. The terminal copies the uplink packet to generate a duplicate packet, and then transmits the uplink packet and the duplicate packet at two or more random, different times. The network is considered to have successfully received either packet, thereby reducing the probability of collision failure.
[0081] In some embodiments, the random access procedure in a non-terrestrial network includes the UE sending a random access preamble (MSG1), followed by the UE listening to the PDCCH to receive a Random Access Response (RAR) message (MSG2). In NTN, the RAR window begins at a certain time interval after the preamble transmission, which is the round-trip time (RTT) between the UE and the eNB. Similarly, after sending MSG3, the UE needs to listen to MSG4 to resolve potential random access contention. The contention resolution timer starts at a certain time interval after MSG3 transmission, which is also the RTT between the UE and the eNB.
[0082] In view of this, embodiments of this disclosure provide a communication method, communication device, communication system, storage medium, and program product. This enables the determination of when to initiate a response reception window when a terminal needs to send multiple copies of an uplink packet, and / or the determination of which temporary identifier (Radio Network Temporary Identifier, RNTI) is used for addressing the PDCCH used by the terminal to receive the response message.
[0083] Figure 2A is an interactive schematic diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 2A, the embodiment of the present disclosure relates to a communication method executed by a communication system 100, the method including:
[0084] In step S2101, the sending end 101 determines multiple sending opportunities corresponding to a data packet.
[0085] In some embodiments, the data packet is a data packet to be sent.
[0086] One sending timing is used to send a data packet once.
[0087] In some embodiments, the sender determines multiple transmission opportunities for a single data packet, and sends the data packet once at each transmission opportunity. That is, the data packet is sent multiple times.
[0088] In some embodiments, a transmission timing includes one or more transmission times.
[0089] In some embodiments, a transmission timing includes one or more transmission periods.
[0090] In some embodiments, a transmission timing corresponds to all symbols allocated within a time slot for transmitting a single data packet.
[0091] In some embodiments, a transmission timing may be a series of symbols spanning time slots for transmitting a single data packet, the symbols being either consecutive or non-consecutive, which is not limited herein.
[0092] In some embodiments, the name of the transmission timing is not limited, and it may be, for example, transmission timing, repeated transmission timing, etc.
[0093] It is understandable that the definition of the timing of transmission can be the same as or similar to the definition of the timing of transmission in related technologies.
[0094] In some embodiments, the sender determines multiple transmission opportunities corresponding to a data packet. The number of transmission opportunities and the transmission resources available for the multiple transmission opportunities can be configured or allocated by at least one of the network device, the administrator, the receiver, and the receiving end. For example, if the sender is a terminal and the receiver is a network device, then the number of transmission opportunities can be configured by the network device, and the transmission resources (i.e., uplink resources) available for the multiple transmission opportunities can be allocated by the network device.
[0095] In some embodiments, the number of transmission opportunities may be indicated or configured by the network device / administrator. The location corresponding to each transmission opportunity in the time domain may be indicated or configured by the network device / administrator.
[0096] In some embodiments, the sender may randomly determine multiple transmission times for a single data packet.
[0097] In some embodiments, the sender may determine multiple transmission opportunities for the data packet based on information such as the priority (e.g., urgency) of the service to which the data packet belongs, the size of the data packet, and available transmission resources.
[0098] In some embodiments, a transmission opportunity corresponds to a transmission resource, and a transmission resource is associated with a temporary identifier (RNTI) of the sending end. The transmission resource, the sending end's temporary identifier, and the correspondence between the transmission resource and the sending end's temporary identifier can all be allocated by the receiving end (e.g., a network device).
[0099] For example, the sender sends a data packet once based on the transmission resources corresponding to the first transmission opportunity (i.e., the first data packet transmission). For example, the sender sends a data packet once based on the transmission resources corresponding to the second transmission opportunity (i.e., the second data packet transmission).
[0100] The transmission resources include at least one of the time domain resources, frequency domain resources, and spatial domain resources.
[0101] In step S2102, the sending end 101 sends a data packet once each time a sending opportunity is reached.
[0102] In some embodiments, when a transmission timing is reached, a data packet is sent according to the transmission resources corresponding to that transmission timing.
[0103] In step S2103, after the sending end 101 has completed sending the data packet to the receiving end 102 at the first sending time, the first timer is started after an interval of a first duration.
[0104] In some embodiments, the first duration is determined based on the time it takes for data, messages, or information to travel one round trip between the sender and receiver. For example, assuming the sender is a terminal and the receiver is a network device, the first duration could be the round-trip time (RTT) between the terminal and the network device.
[0105] This disclosure does not limit the method for determining the first duration. Optionally, the first duration is measured. For example, the round-trip time is measured by sending a reference signal or reference message. Optionally, the first duration is predicted by an AI model. For example, it is predicted based on information such as channel state and distance. Optionally, the first duration is the average or weighted average calculated based on the round-trip time of monitored historical data or signals.
[0106] In some embodiments, when the sending end completes sending a data packet to the receiving end at the first sending opportunity, a first timer is started at a time interval of a first duration from the end time of the first sending opportunity.
[0107] In some embodiments, the sending end is active during the operation of the first timer, and the sending end is able to listen for response messages sent by the receiving end.
[0108] In some embodiments, the name of the first timer is not limited, and it may be, for example, a response receive timer, a listening window, etc.
[0109] In some embodiments, the runtime of the first timer is longer than the second duration, which is configured by the receiving end.
[0110] It should be noted that the second duration can be understood as the waiting time for the sending end to wait for the receiving end to respond to the data packet after it has been sent once. If this duration is exceeded, it can be assumed that the receiving end has not received the data packet sent. That is, the second duration is similar to the running time of the retransmission timer. If the retransmission timer expires, it can be assumed that the receiving end has not received the data packet sent this time, and the data packet can be retransmitted.
[0111] In some embodiments, the runtime of the first timer is the sum of the second duration and a preset threshold.
[0112] In some embodiments, the runtime of the first timer is 1 second or 2 time slots longer than that of the second timer, but this disclosure does not limit this.
[0113] In some embodiments, the transmitting end determines the runtime of the first timer based on the sum of the second and third durations. The runtime of the first timer is the sum of the second and third durations. Optionally, the third duration is the time interval between the end of the first transmission opportunity and the end of the last transmission opportunity. Optionally, the third duration is the time interval between the start of the first transmission opportunity and the start of the last transmission opportunity. Optionally, the third duration is the time interval between the start of the first transmission opportunity and the end of the last transmission opportunity.
[0114] In step S2104, the receiving end 102 sends a response message to the sending end upon receiving the data packet.
[0115] In some embodiments, the receiving end receives data packets. The receiving end can receive data packets sent by the sending end at any given time.
[0116] In some embodiments, the receiving end sends a response message to the sending end after receiving the data packet. The response message is a acknowledgment of the data packet received.
[0117] Optionally, the response message may be an indication that the receiving end has received the data packet.
[0118] Optionally, the response message can be a response to the service requested by the content of the data packet, such as a response message indicating whether the request is accepted, rejected, or related service data requested by the sender.
[0119] In some embodiments, since the sending end sends multiple data packets with the same content each time, the receiving end can respond to only the first data packet received.
[0120] In some embodiments, the receiving end determines a temporary identifier of the sending end associated with the transmission resource based on the transmission resource of the received data packet, and sends a response message to the sending end based on the temporary identifier.
[0121] In step S2105, during the Nth time period of the first timer operation, the sending end 101 listens for the response message sent by the receiving end 102 according to the N temporary identifiers corresponding to the previous N sending opportunities.
[0122] In some embodiments, N is an integer greater than 0.
[0123] In some embodiments, the runtime of the first timer can be divided into multiple time periods. The duration of the Nth time period is the time interval between the Nth transmission opportunity and the (N+1)th transmission opportunity. Optionally, the duration between the end time of the Nth transmission opportunity and the end time of the (N+1)th transmission opportunity is determined as the duration of the Nth time period. Optionally, the duration between the start time of the Nth transmission opportunity and the start time of the (N+1)th transmission opportunity is determined as the duration of the Nth time period. Optionally, the duration between the end time of the Nth transmission opportunity and the start time of the (N+1)th transmission opportunity is determined as the duration of the Nth time period.
[0124] It should be noted that the number of transmission opportunities is the same as the number of time slots included in the runtime of the first timer. For example, if the number of transmission opportunities is K, the runtime of the first timer includes K time slots. The duration of the Nth time slot is the time interval between the Nth and (N+1)th transmission opportunities. Here, N is a positive integer, and N+1 is less than or equal to K. The duration of the last time slot (i.e., the Kth time slot) is the remaining duration of the first timer's runtime after the first K-1 time slots.
[0125] For example, assuming the number of transmission opportunities corresponding to the data packet is K=2, the runtime of the first timer is divided into two time periods. The duration of the first time period during the first timer's operation is the time interval between the first and second transmission opportunities. The duration of the second time period during the first timer's operation is the remaining duration after subtracting the duration of the first time period from the runtime of the first timer.
[0126] In some embodiments, during the Nth time period of the first timer operation, the sending end listens for the response message sent by the receiving end based on the N temporary identifiers corresponding to the previous N sending opportunities.
[0127] For example, suppose the temporary identifier of the sender corresponding to the first sending opportunity is RNTI-1, the temporary identifier of the sender corresponding to the second sending opportunity is RNTI-2, and the temporary identifier of the sender corresponding to the third sending opportunity is RNTI-3. Then, during the first time period of the first timer's operation, the sender listens for the response message sent by the receiver based on the temporary identifier RNTI-1. During the second time period of the first timer's operation, the sender listens for the response message sent by the receiver based on both temporary identifiers RNTI-1 and RNTI-2. During the third time period of the first timer's operation, the sender listens for the response message sent by the receiver based on all three temporary identifiers RNTI-1, RNTI-2, and RNTI-3.
[0128] Since the sender may not have sent a second data packet during the first timer period, this method avoids the sender using temporary identifiers other than RNTI-1 to listen for response messages during the first timer period, thus reducing the sender's listening difficulty, complexity, and energy consumption. Similarly, since the sender may not have sent a third data packet during the second timer period, this method avoids the sender using temporary identifiers other than RNTI-1 and RNTI-2 to listen for response messages during the second timer period, thus reducing the sender's listening difficulty, complexity, and energy consumption.
[0129] It should be noted that the sending end is assumed to be a terminal and the receiving end is a network device. The sending end listening for response messages sent by the receiving end during the first time period of the first timer's operation, based on the temporary identifier RNTI-1, means that the sending end listens for downlink channels (e.g., PDCCH, PDSCH) during the first time period of the first timer's operation by addressing them using the temporary identifier RNTI-1 to obtain the response messages.
[0130] In this embodiment, after the sending end completes sending the data packet at the first sending opportunity, it starts a first timer after a first interval. During the execution of the first timer, it listens for response messages sent by the receiving end in response to the data packet. This solves the problem that in scenarios where data packets are sent multiple times, the sending end does not know which data packet the receiving end will receive (i.e., does not know which data packet the receiving end will respond to), and therefore does not know when to listen for response messages. Furthermore, since the execution length of the first timer is longer than the second interval configured by the receiving end, the sending end can listen for response messages from the receiving end for any of the first or second data packets sent, which increases the success rate of the sending end listening for response messages.
[0131] Furthermore, in the above embodiments, during the Nth time period of the first timer's operation, the sending end listens for the response message sent by the receiving end based on the N temporary identifiers corresponding to the previous N sending opportunities. This ensures that the sending end can listen for the response message while minimizing the processing complexity of the sending end, reducing the difficulty, complexity, and resource consumption of listening for the response message.
[0132] Optionally, the sending end stops the first timer upon receiving a response message.
[0133] Optionally, upon receiving a response message, the sender stops sending data packets; that is, even if the time to send arrives, the sender will not send data packets after receiving a response message.

[0147] Figure 2B is an interactive schematic diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 2B, the embodiment of the present disclosure relates to a communication method executed by a communication system 100, the method including:
[0148] In step S2201, the sending end 101 determines multiple sending opportunities corresponding to a data packet.
[0149] The optional implementation of step S2201 can be found in the optional implementation of step S2101 in Figure 2A, and other related parts in the embodiments involved in Figure 2A, which will not be repeated here.
[0150] In step S2202, the sending end 101 sends a data packet once each time a sending opportunity is reached.
[0151] The optional implementation of step S2202 can be found in the optional implementation of step S2102 in Figure 2A and other related parts in the embodiments involved in Figure 2A, which will not be repeated here.
[0152] In step S2203, after the sending end 101 has completed sending the data packet to the receiving end 102 at the first sending time, the first timer is started after an interval of a first duration.
[0153] The optional implementation of step S2203 can be found in the optional implementation of step S2103 in Figure 2A, and other related parts in the embodiments involved in Figure 2A, which will not be repeated here.
[0154] In step S2204, the receiving end 102 sends a response message to the sending end upon receiving the data packet.
[0155] The optional implementation of step S2204 can be found in the optional implementation of step S2104 in Figure 2A, and other related parts in the embodiments involved in Figure 2A, which will not be repeated here.
[0156] In step S2205, during the first timer operation, the sending end 101 listens for the response message of the receiving end 102 to the data packet according to all temporary identifiers corresponding to all sending opportunities.
[0157] In some embodiments, during the execution of the first timer, the sending end listens for the receiving end's response messages to data packets based on all temporary identifiers corresponding to all sending opportunities. For example, assuming there are 3 sending opportunities, the temporary identifier for the sending end corresponding to the first sending opportunity is RNTI-1, the temporary identifier for the sending end corresponding to the second sending opportunity is RNTI-2, and the temporary identifier for the sending end corresponding to the third sending opportunity is RNTI-3. Then, at any time during the execution of the first timer, the sending end listens for the response messages sent by the receiving end based on the temporary identifiers RNTI-1, RNTI-2, and RNTI-3.
[0158] In the above embodiment, after the sending end completes sending a data packet at the first sending opportunity, it starts a first timer after a first interval. During the execution of the first timer, it listens for response messages from the receiving end to the data packets. This solves the problem that in scenarios where data packets are sent multiple times, the sending end does not know which sent data packet the receiving end will receive (i.e., does not know which sent data packet the receiving end will respond to), and therefore does not know when to listen for response messages. Furthermore, since the execution length of the first timer is longer than the second interval configured by the receiving end, the sending end listens for response messages from the receiving end to the data packets based on all temporary identifiers corresponding to all sending opportunities during the execution of the first timer. Therefore, the sending end can listen for response messages from the receiving end to any of the first or second sent data packets, which increases the success rate of the sending end listening for response messages.
[0159] The communication method involved in the embodiments of this disclosure may include at least one of steps S2201 to S2205. For example, step S2203 may be implemented as a separate embodiment, step S2205 may be implemented as a separate embodiment, steps S2201 and S2203 may be implemented as separate embodiments, and steps S2204 and S2205 may be implemented as separate embodiments, but are not limited thereto.

For example, the order of steps S2202 and S2204 can be interchanged or they can be performed simultaneously.

[0166] Figure 3 is an interactive schematic diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 3, the embodiment of the present disclosure relates to a communication method executed by a communication system 100, the method including:
[0167] In step S301, the sending end 101 determines multiple sending opportunities corresponding to a data packet.
[0168] In step S302, after the sending end 101 has completed sending the data packet at the first sending time, it starts the first timer after an interval of the first duration.
[0169] The runtime of the first timer is longer than that of the second timer, which is configured by the receiving end.
[0170] Optionally, the transmitting end determines the runtime of the first timer based on the sum of the second duration and the third duration, wherein the third duration is the time interval between the end time of the first transmission opportunity and the end time of the last transmission opportunity.
[0171] In step S303, the receiving end 102 sends a response message to the sending end 101 based on the sending end temporary identifier associated with the transmission resource of the received data packet.
[0172] Optionally, a transmission opportunity corresponds to a transmission resource, and a transmission resource is associated with a temporary identifier of the sending end.
[0173] In step S304, during the first timer operation, the sending end 101 listens for the response message of the receiving end 102 to the data packet.
[0174] Optionally, the implementation of the sending end listening for the receiving end's response message to the data packet during the first timer's operation includes: the sending end listening for the receiving end's response message to the data packet based on at least one of a plurality of temporary identifiers corresponding to a plurality of transmission opportunities during the first timer's operation. For example, the sending end listens for the receiving end's response message to the data packet based on the temporary identifier corresponding to the first transmission opportunity during the first timer's operation. For example, the sending end listens for the receiving end's response message to the data packet based on the temporary identifiers corresponding to the first and second transmission opportunities during the first timer's operation. For example, the sending end listens for the receiving end's response message to the data packet based on the temporary identifiers corresponding to the first and second transmission opportunities during a certain time period during the first timer's operation, and listens for the receiving end's response message to the data packet based on the temporary identifier corresponding to the third transmission opportunity during another certain time period. However, this is not limited to these embodiments.
[0175] Optionally, the implementation method in which the sending end listens for the receiving end's response message to the data packet according to at least one of the multiple temporary identifiers corresponding to multiple transmission opportunities during the operation of the first timer includes: during the Nth time period of the operation of the first timer, the sending end listens for the receiving end's response message to the data packet according to the N temporary identifiers corresponding to the previous N transmission opportunities, where N is an integer greater than 0; wherein, the duration of the Nth time period is the time interval between the Nth transmission opportunity and the N+1th transmission opportunity.
[0176] Optionally, the implementation method in which the sending end listens for the receiving end's response message to the data packet according to at least one of the multiple temporary identifiers corresponding to multiple sending opportunities during the first timer operation includes: the sending end listens for the receiving end's response message to the data packet according to all temporary identifiers corresponding to all sending opportunities during the first timer operation.
[0177] Optionally, the duration of the Nth time period is the time interval between the end time of the Nth transmission opportunity and the end time of the (N+1)th transmission opportunity.
[0178] Optionally, the first duration is determined based on the time it takes for data or messages to travel one round trip between the sender and receiver.

[0180] Figure 4 is a flowchart illustrating a communication method according to an embodiment of the present disclosure. As shown in Figure 4, this embodiment relates to a communication method executed by a sending end 101, the method including:
[0181] In step S401, the sending end 101 determines multiple sending opportunities corresponding to a data packet.
[0182] The optional implementations of step S401 can be found in the optional implementations of step S2101 in Figure 2A, step S2201 in Figure 2B, and step S301 in Figure 3, as well as other related parts in the embodiments involved in Figures 2A, 2B, and 3, which will not be repeated here.
[0183] In step S402, after the sending end 101 has completed sending the data packet at the first sending time, it starts the first timer after an interval of the first duration.
[0184] The optional implementations of step S402 can be found in step S2103 of Figure 2A, step S2203 of Figure 2B, the optional implementations of step S302 of Figure 3, and other related parts in the embodiments involved in Figures 2A, 2B, and 3, which will not be repeated here.
[0185] In step S403, during the first timer operation, the sending end 101 listens for the response message of the receiving end 102 to the data packet.
[0186] The optional implementations of step S403 can be found in step S2105 of Figure 2A, step S2205 of Figure 2B, and step S304 of Figure 3, as well as other related parts in the embodiments involved in Figures 2A, 2B, and 3, which will not be repeated here.
[0187] In some embodiments, the steps and their optional implementations in other embodiments described before or after this embodiment, as well as other related parts in the specification, can be referred to, and will not be repeated here.
[0188] In some embodiments, the terminal sends multiple copies of an uplink packet based on randomly determined time intervals and starts a receive window to receive response messages within the receive window.
[0189] In some embodiments, the determination of the response reception timer duration includes: the terminal determining multiple transmission opportunities for sending multiple copies of uplink packets, wherein the number of transmission opportunities and the uplink resources available for the multiple transmission opportunities can be configured by the network. After sending the first copy of the uplink packet, the terminal starts a response reception timer or window after a time interval, wherein the time interval is the RTT between the UE and the eNB. The duration of the response reception timer or window is the sum of the duration parameter value of the response reception timer or window configured by the network and a first duration. The first duration is the duration between the end time of the first transmission copy selected by the terminal and the end time of the last transmission copy selected by the terminal.
[0190] In some embodiments, the terminal sends multiple uplink packet copies, with time intervals between the copies sequentially designated as T1, T2, T3, ... where T1 represents the time interval between the end times of the first and second copies, and T2 represents the time interval between the end times of the second and third copies.
[0191] In some embodiments, the RNTI for listening to response messages is determined as follows: During the period from 0 to T1 when the response receive timer / window is open, the UE listens for response messages according to RNTI-1, where RNTI-1 is associated with the time-frequency resources used in the first replica transmission. Optionally, during the period from T1 to T1+T2 when the response receive timer / window is open, the UE listens for response messages according to RNTI-1 and RNTI-2, where RNTI-2 is associated with the time-frequency resources used in the second replica transmission. Optionally, during the period from T1+T2 to T1+T2+T3 when the response receive timer / window is open, the UE listens for response messages according to RNTI-1, RNTI-2, and RNTI-3, where RNTI-3 is associated with the time-frequency resources used in the third replica transmission. And so on.
[0192] In some embodiments, the RNTI for listening to response messages is determined by: after the response receiving timer / window is started, the terminal listens to response messages by using multiple RNTIs associated with the time-frequency resources used by multiple copy transmissions.
[0193] In some embodiments, the steps and their optional implementations in other embodiments described before or after this embodiment, as well as other related parts in the specification, can be referred to, and will not be repeated here.
[0194] This disclosure also proposes an apparatus (also referred to as a communication device, etc.) for implementing any of the above methods. For example, an apparatus is proposed that includes units or modules for implementing the steps performed by the terminal in any of the above methods. The terminal is either a transmitter or a receiver. Furthermore, another apparatus is proposed that includes units or modules for implementing the steps performed by a network device (e.g., an access network device, a core network functional node, a core network device, etc.) in any of the above methods. The network device is either a transmitter or a receiver.
[0195] It should be understood that the division of units or modules in the above device is only a logical functional division. In actual implementation, they can be fully or partially integrated into a single physical entity, or they can be physically separated. Furthermore, the units or modules in the device can be implemented by a processor calling software: for example, the device includes a processor connected to a memory containing instructions. The processor calls the instructions stored in the memory to implement any of the above methods or to implement the functions of the units or modules in the above device. The processor can be, for example, a general-purpose processor, such as a Central Processing Unit (CPU) or a microprocessor, and the memory can be internal or external to the device. Alternatively, the units or modules in the device can be implemented in the form of hardware circuits. The functionality of some or all of the units or modules can be achieved through the design of these hardware circuits, which can be understood as one or more processors. For example, in one implementation, the hardware circuit is an application-specific integrated circuit (ASIC). The functionality of some or all of the units or modules is achieved through the design of the logical relationships between the components within the circuit. In another implementation, the hardware circuit can be implemented using a programmable logic device (PLD), such as a field-programmable gate array (FPGA). This PLD can include a large number of logic gates, and the connection relationships between these logic gates are configured through configuration files, thereby achieving the functionality of some or all of the units or modules. All units or modules in the above device can be implemented entirely through processor-called software, entirely through hardware circuits, or partially through processor-called software with the remaining portion implemented through hardware circuits.
[0196] In this embodiment, the processor is a circuit with signal processing capabilities. In one implementation, the processor can be a circuit with instruction read and execute capabilities, such as a Central Processing Unit (CPU), a microprocessor, a graphics processing unit (GPU) (which can be understood as a microprocessor), or a digital signal processor (DSP). In another implementation, the processor can implement certain functions through the logical relationships of hardware circuits. The logical relationships of the aforementioned hardware circuits are fixed or reconfigurable. For example, the processor is a hardware circuit implemented using an application-specific integrated circuit (ASIC) or a programmable logic device (PLD), such as an FPGA. In a reconfigurable hardware circuit, the process of the processor loading a configuration document and configuring the hardware circuit can be understood as the process of the processor loading instructions to implement the functions of some or all of the above units or modules. Furthermore, it can also be a hardware circuit designed for artificial intelligence, which can be understood as an ASIC, such as a Neural Network Processing Unit (NPU), a Tensor Processing Unit (TPU), or a Deep Learning Processing Unit (DPU).
