Background Art

[0003] With the development of communications, the fifth-generation (5G) communication system has gradually penetrated into some multimedia services with high real-time performance and large data capacity requirements, such as video transmission, cloud gaming (CG), and extended reality (XR). Multimedia services have strict requirements for data transmission delay. Therefore, how to meet the data transmission delay requirements in the communication process has become a problem that needs to be considered.

Summary of the Invention

[0004] Embodiments of this application provide a communication method and a communication apparatus to complete data transmission within the delay budget of the data. Therefore, the communication performance is improved.

Means for Solving the Problems

[0005] According to the first aspect, a communication method is provided. This method can be executed by a first device. The first device may be a network device or a terminal device, may be a chip or a circuit in the terminal device, may be a chip or a circuit in the network device, may be a logical module or software capable of implementing all or part of the functions of the network device, or may be a logical module or software capable of implementing all or part of the functions of the terminal device. This is not limited in this application. The method includes a step of receiving first configuration information and a step of transmitting time information corresponding to data based on the first configuration information, where the time information is generated based on the acquisition time of the data or the remaining delay budget of the data.

[0006] In a possible embodiment, the time information is used for scheduling and transmitting the data, and the scheduling and transmitting of the data can be understood as configuring resources for the data so that the transmission of the data is executed with the configured resources.

[0007] For example, the time information directly / indirectly indicates the acquisition time of the data or directly / indirectly indicates the remaining delay budget of the data.

[0008] According to the foregoing solution, when the first device is configured to transmit time information corresponding to data, the first device transmits the time information corresponding to the data, whereby the side scheduling the data can determine the remaining delay budget of the data. For example, the time information is related to the time point when the data is acquired. In this case, after receiving the time information, the side scheduling the data can determine the remaining delay budget of the data based on the delay budget of the data and the time information. Alternatively, the time information is related to the remaining delay budget of the data. In this case, after receiving the time information, the side scheduling the data can determine the remaining delay budget of the data based on the time information. In this way, the data transmission is completed within the delay budget of the data. Therefore, the communication performance is improved.

Embodiments for Carrying Out the Invention

[0069] The following describes the technical solutions in the embodiments of the present application with reference to the accompanying drawings.

[0070] FIG. 1 shows a network architecture according to an embodiment of the present application.

[0071] The communication system 100 shown in FIG. 1 includes a network device 10 and at least one terminal device, for example, terminal device 20 and terminal device 21. In the communication system, the terminal devices 20 and 21 can transmit uplink data / signals / information to the network device 10, and the network device 10 can transmit downlink data / signals / information to either of the terminal devices 20 and 21.

Of course, the communication method provided in the embodiments of the present application may alternatively include only some of the devices or transmission nodes shown in FIG. 1. This is not limited in the embodiments of the present application.

[0073] The foregoing network architecture used in the embodiments of the present application is merely an example for explanation, and the network architecture used in the embodiments of the present application is not limited thereto. Any network architecture capable of implementing the functions of the foregoing devices is applicable to the embodiments of the present application.

[0075] The terminal device may be a wireless terminal device capable of receiving scheduling and instruction information of a network device. The terminal device may also be a device that provides a voice and / or data connection to a user, a handheld device having a wireless connection function, or another processing device connected to a wireless modem.

[0076] The terminal device in the embodiments of this application may also be referred to as a terminal, access terminal, subscriber unit, user equipment (UE), subscriber station, mobile station, remote station, remote terminal, mobile device, user terminal, wireless communication device, user agent, or user device. The terminal device is a device that includes a wireless communication function (providing voice / data connection to the user), for example, a handheld device or in-vehicle device with a wireless connection function. The terminal in the embodiments of this application may be a mobile phone, tablet computer (pad), computer with a wireless transceiver function, train, airplane, mobile internet device (MID), virtual reality (VR) terminal, augmented reality (AR) terminal, wireless terminal for industrial control (such as a robot), wireless terminal for vehicle internet (such as an in-vehicle device, vehicle device, in-vehicle module, or vehicle), wireless terminal for self-driving, wireless terminal for remote medical, wireless terminal for smart grid, wireless terminal for transportation safety, wireless terminal for smart city, wireless terminal for smart home, cellular phone, cordless phone, session initiation protocol (SIP) phone, wireless local loop (WLL) station, personal digital assistant (PDA), handheld device with a wireless communication function, computing device, another processing device connected to a wireless modem, in-vehicle device, wearable device, terminal of a 5G network, or terminal of a future developed network.All or some of the functions of the terminal device in this application may be implemented by using software functions operating on hardware, or may be implemented by using virtualized functions instantiated on a platform (for example, a cloud platform).

[0077] A wearable device, which may also be referred to as a wearable intelligent device, is a general term for wearable devices such as glasses, gloves, watches, clothing, and shoes developed by applying wearable technology to the intelligent design of daily wear. A wearable device is a portable device that is worn directly on the body or incorporated into the user's clothing or accessories. A wearable device is a hardware device that implements powerful functions through software support, data exchange, and cloud interaction. In a broad sense, an intelligent wearable device includes a full-function large device that can implement complete or partial functions without relying on a smartphone, such as a smartwatch or smart glasses, and various smart bands or smart jewelry used for monitoring physical symptoms, etc., which are devices specialized for only one type of application function and need to be used together with other devices such as smartphones.

[0078] The network device may be a device within a wireless network. For example, the network device may be a device that provides a wireless communication function to the terminal device and is arranged in a wireless access network. For example, the network device may be a radio access network (RAN) node that connects the terminal device to a wireless network and may also be referred to as an access network device.

[0079] The network device includes, but is not limited to, an evolved NodeB (eNB), a radio network controller (RNC), a NodeB (NB), a base station controller (BSC), a base transceiver station (BTS), a home base station (e.g., home evolved NodeB, HeNB or home NodeB, HNB), a baseband unit (BBU), a server, a wearable device, a vehicle-mounted device, an access point (AP) of a WIFI system, a wireless relay node, a wireless backhaul node, a transmission point (TP), or a transmission and reception point (TRP). Alternatively, the network device may be, for example, a gNB or a transmission point (TRP or TP) in a 5G system such as an NR system, or one antenna panel or a group of antenna panels (including multiple antenna panels) of a base station in a 5G system. Or, alternatively, the network device may be a network node that constitutes a gNB or a transmission point, such as a baseband unit (BBU) or a distributed unit (DU). The base station may be a macro base station, a micro base station, a pico base station, a small cell, a relay station, or a balloon station, etc. It can be understood that all or part of the functions of the network device in this application may alternatively be implemented using software functions operating on hardware, or may be implemented using virtualized functions instantiated on a platform (e.g., a cloud platform).

[0080] In some configurations, the gNB may include a central unit (CU) and a DU. The gNB may further include an active antenna unit (AAU). The CU performs some functions of the gNB, and the DU performs some functions of the gNB. For example, the CU is responsible for the processing of non-real-time protocols and services, and implements the functions of the radio resource control (RRC) layer and the packet data convergence protocol (PDCP) layer. The DU is responsible for the processing of physical layer protocols and real-time services, and implements the functions of the radio link control (RLC) layer, the media access control (MAC) layer, and the physical (PHY) layer. The AAU performs some physical layer processing functions, radio frequency processing, and functions related to active antennas. The information of the RRC layer is generated by the CU and is finally encapsulated into the information of the PHY layer or converted from the information of the PHY layer at the PHY layer of the DU. Therefore, in this architecture, it is also possible to consider that the upper layer signaling, for example, the RRC layer signaling, is transmitted by the DU or transmitted by the DU and the AAU. It can be understood that the network device can be a device including one or more of the CU node, the DU node, and the AAU node. In addition, the CU may be classified as a network device within the radio access network (RAN), or the CU may be classified as a network device within the core network (CN). This is not limited in this application.

[0081] Today, with the continuous progress and improvement of related technologies for multimedia services (e.g., CG and XR services), network delay requirements have become more stringent to enhance immersion. For example, in a remote control system, to ensure a high fidelity of tactile and remote operations, the sampling rate of tactile information should not be less than 1 kHz, and the transmission delay requirement for each sample reaches 5 ms. Therefore, in some multimedia services where the transmission delay requirements are becoming increasingly stringent, how to complete the transmission of data within the delay budget is a problem that needs to be considered, and the data delay budget can be determined based on the transmission delay requirements of the service.

[0082] FIG. 2 is an interaction flowchart of a data scheduling method according to an embodiment of the present application. In FIG. 2, for the purpose of explaining this method, an example where a network device and a terminal device are used as the executors of the interaction is used. However, the executors of the interaction are not limited in the present application. For example, the network device in FIG. 2 may alternatively be a chip, a chip system, or a processor that supports the network device when implementing this method, or may be a logical module or software that can implement all or part of the functions of the network device. The terminal device in FIG. 2 may alternatively be a chip, a chip system, or a processor that supports the terminal device when implementing this method, or may be a logical module or software that can implement all or part of the functions of the terminal device. The method 200 shown in FIG. 2 includes the following steps.

[0083] S210: The terminal device sends a scheduling request (SR), and the scheduling request is used to request scheduling resources for data. Correspondingly, the network device receives the scheduling request.

[0084] In a possible implementation, when the terminal device needs to send uplink data, the terminal device may send a scheduling request to the network device to request resources for sending the uplink data to the network device.

[0085] For example, the scheduling request may be carried on a physical uplink control channel (PUCCH). The scheduling request includes 1 bit of information and is used to notify the network device whether there is uplink data to be transmitted. The transmission period and transmission offset (e.g., slot offset) of the scheduling request on different logical channels (LCH) may be the same or different, and different logical channels may be configured separately.

[0086] For example, the scheduling request may be carried on PUCCH format 0 or PUCCH format 1. PUCCH format 0 may also be further used to send hybrid automatic repeat request (HARQ) ACK / NACK (positive response / negative response) feedback. The information transmitted in PUCCH format 0 includes 1 bit or 2 bits (corresponding to the case where the scheduled physical downlink shared channel (PDSCH) includes two codewords). PUCCH format 0 may occupy one resource block in the frequency domain and one or two symbols in the time domain.

[0087] In a possible implementation, PUCCH format 0 is generated based on a Zadoff-Chu (ZC) sequence. The information carried by the ZC sequence can be indicated by the final value of the sequence cyclic shift. The final value of the sequence cyclic shift is the value m of the sequence cyclic shift CSIt can be determined based on

[0088] For example, when the information to be transmitted is HARQ-ACK information, m corresponding to the HARQ-ACK information CS can be determined using the correspondence between the HARQ-ACK information and the sequence cyclic shift of PUCCH format 0. When the transmitted HARQ-ACK information is 1 bit, the correspondence between the value of the HARQ-ACK information bit (i.e., the HARQ-ACK value) and the sequence cyclic shift of PUCCH format 0 is shown in Table 1, and m corresponding to the HARQ-ACK value CS can be determined from the correspondence shown in Table 1. When the transmitted HARQ-ACK information is 2 bits, the correspondence between the HARQ-ACK value and the sequence cyclic shift of PUCCH format 0 is shown in Table 2, and m corresponding to the HARQ-ACK value CS can be determined from the correspondence shown in Table 2.

[0089]

Table 1

[0090]

Table 2

[0091] Table 2 is used as an example. When the HARQ-ACK value is {0, 1}, m CS is determined to be 3, and the final value of the sequence cyclic shift of PUCCH format 0 that carries the HARQ-ACK value can be further determined based on m CS = 3.

[0092] When HARQ-ACK information and a scheduling request are multiplexed, in other words, when the scheduling request and the HARQ-ACK information are transmitted simultaneously, the scheduling request is a positive request (specifically, it notifies the network device that there is data to be transmitted). The terminal device may alternatively indicate the HARQ-ACK information and the positive scheduling request by a cyclic shift method. For example, when the HARQ-ACK information and the positive scheduling request to be transmitted are 1 bit, the correspondence between the HARQ-ACK information bit and the value of the positive scheduling request and the sequence cyclic shift of PUCCH format 0 is shown in Table 3. When the HARQ-ACK information bit and the positive scheduling request to be transmitted are 2 bits, the correspondence between the HARQ-ACK information bit and the value of the positive scheduling request and the sequence cyclic shift of PUCCH format 0 is shown in Table 4. The value of the positive scheduling request is not shown in Table 3 or Table 4. This is because the positive scheduling request is implicitly indicated and does not actually occupy an information bit. In other words, when the value of the sequence cyclic shift is the value in Table 3 and Table 4, the HARQ-ACK value indicates the HARQ-ACK information and the positive scheduling request. The resource for transmitting the HARQ-ACK information, or the HARQ-ACK information and the positive scheduling request, is configured by the network device. Therefore, m CS When m = 3 or 9, the network device may identify whether to interpret the HARQ-ACK information indicated by 2 bits based on Table 2, or to interpret the HARQ-ACK information indicated by 1 bit and the positive scheduling request based on Table 3.

[0093]

Table 3

[0094]

Table 4

[0095] Table 4 is used as an example. When the HARQ-ACK value is {0,1}, based on Table 2, m CS is determined to be 4, and the final value of the sequence cyclic shift of the PUCCH format 0 sequence that carries the HARQ-ACK information and the positive scheduling request can be further determined based on m CS = 4.

[0096] S220: The network device transmits scheduling information. Correspondingly, the terminal device receives the scheduling information.

[0097] In a possible implementation, after receiving the scheduling request, the network device transmits scheduling information to the terminal device in response to the scheduling request.

[0098] For example, the scheduling information may be carried on a physical downlink control channel (PDCCH). For example, the scheduling information is transmitted to the terminal device using downlink control information (DCI) format 0_0 or 0_1.

[0099] For example, since the network device does not know the amount of uplink data transmitted by the terminal device, the network device may perform data scheduling for the terminal device based on a small amount of fixed data volume.

[0100] For example, the scheduling information may include physical uplink shared channel (PUSCH) resource information.

[0101] If the terminal device has not received the scheduling information transmitted by the network device, the terminal device may continue to transmit the scheduling request.

[0102] S230: The terminal device transmits data. Correspondingly, the network device receives the data.

[0103] In a possible implementation, after receiving the scheduling information, the terminal device transmits data to the network device based on the scheduling information.

[0104] For example, the scheduling information includes PUSCH resource information, and the terminal device transmits data on the PUSCH resources allocated by the network device. The data includes buffer status report (BSR) information, and the buffer status report information is used to notify the network device of the amount of data that still needs to be transmitted. When the BSR is greater than 0, the network device may continue to perform scheduling for the terminal device. Specifically, the network device continues to transmit scheduling information to the terminal device via PDCCH, and then the terminal device continues to perform data transmission on the PUSCH resources indicated by the scheduling information.

[0105] In a time division duplex (TDD) system, the ratio of the number of uplink slots to the number of downlink slots and the sequence of uplink slots and downlink slots can be preconfigured. The network device can only receive scheduling requests in uplink slots, but the time when the terminal device acquires data can be earlier than the time corresponding to the slot. As a result, in the data scheduling solution of method 200, the network device cannot be aware of the exact time when the terminal device acquires data.

[0106] For example, the case where the TDD slot configuration is DDDSU is shown in FIG. 3. D is a downlink slot, U is an uplink slot, and S represents a special slot. The special slot may include both symbols used for uplink transmission and symbols used for downlink transmission. When the network device uses the transmission time point of the scheduling request as the data acquisition time point, the error can reach 5 slots compared to the actual data acquisition time point. If the system uses a 15 kHz sub-carrier spacing (SCS) and 1 slot is 1 ms, the error can reach 5 ms. When the TDD slot configuration is DDDDD DDSUU and the network device uses the transmission time point of the scheduling request as the data acquisition time point, the error can reach 9 slots compared to the actual data acquisition time point. If each slot is 1 ms, the error can reach 9 ms.

[0107] An example where the TDD slot configuration is DDDSU is used for illustration. The data delay budget is 15 ms. In other words, it is assumed that the data is invalid after the fourth uplink slot shown in FIG. 3 ends. Therefore, the data transmission needs to be completed within the delay budget. When using the end time point of the second uplink slot when the scheduling request is transmitted as the data acquisition time point, the network device schedules and transmits the data within 15 ms after the second uplink slot based on the data delay budget. However, the actual data acquisition time point is the end time point of the first uplink slot. As a result, the data transmitted after the fourth uplink slot becomes invalid.

[0108] In other words, when the network device does not know the exact data acquisition time point on the terminal device side, it is difficult for the network device to complete the data transmission within the data delay budget.

[0109] The data delay budget can also be understood as the valid time of the data. If the actual transmission delay of the data exceeds the data delay budget, the data becomes invalid. For example, the data delay budget is the packet delay budget (PDB). The PDB is the maximum transmission delay that can be tolerated in the data packet transmission process between the user plane function (UPF) network element and the terminal device. If the transmission delay of the data packet between the UPF and the terminal device exceeds the PDB, the data packet may be wasted for the receiving side. In this embodiment of the present application, the data delay budget can be the maximum transmission delay that can be permitted in the data transmission process between the network device (for example, the base station) and the terminal device, that is, the access network (AN) PDB. Alternatively, the data delay budget may be the maximum transmission delay that can be tolerated in the data transmission process between the network device (for example, the base station) and another network device (for example, another base station). Alternatively, the data delay budget may be the maximum transmission delay that can be permitted in the data transmission process between the terminal device and another terminal device.

[0110] The data acquisition time can be understood as the time when the terminal device acquires the data, and the time when the data is acquired can be understood as the time when the data is delivered / arrives at the protocol layer (for example, the MAC layer, the RLC layer, or the PDCP layer). For example, the data acquisition time is the time when the MAC entity, the RLC entity, or the PDCP entity acquires the data. Alternatively, the data acquisition time may be represented as the slot, subframe, or frame number when the MAC entity, the RLC entity, or the PDCP entity acquires the data. The data acquisition time may alternatively be understood as the time when the terminal device is ready to transmit the data. This is not limited in the present application.

[0111] In view of the foregoing problems, one embodiment of the present application provides a communication method for completing data transmission within a data delay budget. Therefore, the communication performance is improved.

[0112] FIG. 4 is an interaction flowchart of a communication method according to an embodiment of the present application. The method 400 shown in FIG. 4 includes the following steps.

[0113] Optionally, in S410, the first device transmits first configuration information, and the first configuration information is used to configure the transmission of time information corresponding to the data. Correspondingly, the second device receives the first configuration information.

[0114] The first device may be a terminal device or a network device, and the second device may be a terminal device or a network device. The first device and the second device include, but are not limited to, the following cases: namely, the first device is a terminal device and the second device is a network device, the first device is a terminal device and the second device is a terminal device, and the first device is a network device and the second device is a network device.

[0115] It should be understood that the executors listed in the foregoing cases are merely examples. This is not limited in the present application. For example, the first device may alternatively be a chip, a chip system, or a processor that supports a network device or a terminal device when implementing this method, or a logic module or software that can implement all or part of the functions of a network device or a terminal device. The second device may alternatively be a chip, a chip system, or a processor that supports a terminal device or a network device when implementing this method, or a logic module or software that can implement all or part of the functions of a terminal device or a network device.

[0116] In a possible embodiment, the first configuration information includes a field, and the field indicates whether the second device needs to transmit time information corresponding to the data.

[0117] For example, the data is data having a delay budget, and when the transmission delay of the data exceeds the delay budget, the data becomes invalid. When the second device receives the first configuration information and the first configuration information is used to configure that the second device needs to transmit time information corresponding to the data for the acquired data, the second device may transmit the time information corresponding to the data to the first device. When the first configuration information received by the second device is not used to configure the second device to transmit time information corresponding to the data for the acquired data, the second device cannot transmit the time information corresponding to the data to the first device.

[0118] In a possible embodiment, the first configuration information is configuration information of a logical channel or a logical channel group (LCG).

[0119] For example, the first configuration information is configuration information of a logical channel, and the configuration information includes an enhanced-BSR (enhanced-BSR) field. When the enhanced-BSR field is set to true (or another agreed value #1), it indicates that the logical channel supports enhanced BSR. In other words, it indicates that the first configuration information is used to configure the second device to transmit time information corresponding to the data. Conversely, for example, when the enhanced-BSR field is set to false (or another agreed value #2), it indicates that the first configuration information is used to configure that the second device does not need to transmit time information corresponding to the data. The names of the foregoing fields are merely examples. This is not limited in this application.

[0120] The following shows an example of a configuration including an enhanced-BSR field. Example #1 (when the enhanced-BSR field is set to true): LogicalChannelConfig::=SEQUENCE{ … logicalChannelGroup INTEGER(LCG-ID) …enhanced-BSR ENUMERATED{true} … Example #2 (when the enhanced-BSR field is set to false): LogicalChannelConfig::=SEQUENCE{ … logicalChannelGroup INTEGER(LCG-ID) … enhanced-BSR ENUMERATED{false} …

[0121] The LCG-identifier (identifier, ID) indicates the specific logical channel group to which the logical channels configured in the example belong, and the maximum value of the LCG-ID can be 7. This is not limited in this application.

[0122] In the foregoing example, it should be understood that the enhanced-BSR field is configuration information of the enhanced-BSR information, and the enhanced-BSR information may include time information corresponding to the data. Specifically, whether the enhanced-BSR information includes time information corresponding to the data is configured using the enhanced-BSR field. When the enhanced-BSR field is used to configure that the enhanced-BSR information includes time information corresponding to the data, for example, when the enhanced-BSR field is set to true, the enhanced-BSR information includes time information corresponding to the data. When the enhanced-BSR field is used to configure that the enhanced-BSR information does not include time information corresponding to the data, for example, when the enhanced-BSR field is set to false, the enhanced-BSR information does not include time information corresponding to the data. The enhanced-BSR information that does not include time information corresponding to the data may be understood as the BSR. The foregoing enhanced-BSR information is an example of the name of the information including time information corresponding to the data. This is not limited in this application.

[0123] For example, the first configuration information is an enhanced-SR field within a SchedulingRequestToAddMod information element. When the enhanced-SR field is set to true (or another agreed value #3), it indicates that the first configuration information is used to configure the second device to transmit time information corresponding to the data. Conversely, for example, when the enhanced-SR field is set to false (or another agreed value #4), it indicates that the first configuration information is used to configure that the second device does not need to transmit time information corresponding to the data. The names of the foregoing fields are merely examples. This is not limited in this application.

[0124] The following shows an example of a configuration including the enhanced-SR field. Example #1 (when the enhanced-SR field is set to true): SchedulingRequestToAddMod::=SEQUENCE{ schedulingRequestId SchedulingRequestId, sr-ProhibitTimer ENUMERATED{ms1,ms2,ms4,ms8,ms16,ms32,ms64,ms128}OPTIONAL,--Need S sr-TransMax ENUMERATED{n4,n8,n16,n32,n64,spare3,spare2,spare1} enhanced-SR ENUMERATED{true} Example #2 (when the enhanced-SR field is set to false): SchedulingRequestToAddMod::=SEQUENCE{ schedulingRequestId SchedulingRequestId, sr-ProhibitTimer ENUMERATED{ms1,ms2,ms4,ms8,ms16,ms32,ms64,ms128}OPTIONAL,--Need S sr-TransMax ENUMERATED{n4,n8,n16,n32,n64,spare3,spare2,spare1} enhanced-SR ENUMERATED{false}

[0125] In the foregoing example, it should be understood that the enhanced-SR field is configuration information of the enhanced-SR information, and the enhanced-SR information may include time information corresponding to the data. Specifically, whether the enhanced-SR information includes time information corresponding to the data is configured using the enhanced-SR field. When the enhanced-SR field is used to configure that the enhanced-SR information includes time information corresponding to the data, for example, when the enhanced-SR field is set to true, the enhanced-SR information includes time information corresponding to the data. When the enhanced-SR field is used to configure that the enhanced-SR information does not include time information corresponding to the data, for example, when the enhanced-SR field is set to false, the enhanced-SR information does not include time information corresponding to the data. The enhanced-SR information that does not include time information corresponding to the data may be understood as a scheduling request. The foregoing enhanced-SR information is an example of the name of information including time information corresponding to the data. This is not limited in the present application.

[0126] S420: The second device transmits time information corresponding to the data, and the time information is generated based on the acquisition time of the data or the remaining delay budget of the data. Correspondingly, the first device receives the time information corresponding to the data.

[0127] In a possible implementation, after receiving the first configuration information (the first configuration information is used to configure that the second device needs to transmit time information corresponding to the data), the second device transmits time information corresponding to the data based on the first configuration information when the second device acquires the data.

[0128] For example, uplink control information (UCI) or media access control control element (MAC CE) includes time information corresponding to data.

[0129] In a possible implementation, the time information is any one of the following, namely, the time interval between the acquisition time of the data and the transmission time of the time information, the time interval between the acquisition time of the data and the transmission time of the scheduling request, where the scheduling request is used to request the scheduling resource of the data, or the time interval, or the difference between the delay budget of the data and the remaining delay budget of the data, and the time information is generated based on any one of them.

[0130] The transmission time of the time information may be understood as the time when the time information is actually transmitted, or may be understood as the trigger time of the time information. The trigger time of the time information may be understood as the generation time or the determination time of the time information. For example, after acquiring the data, the first device determines the acquisition time of the data, and the acquisition time is the determination time of the time information. Alternatively, after acquiring the data, the first device may determine whether the time information corresponding to the data needs to be transmitted based on the first configuration information. When the first device determines that the time information corresponding to the data needs to be transmitted based on the first configuration information, the determination time is the trigger time of the time information. When the transmission time of the time information is understood as the trigger time of the time information, the transmission time of the time information is not the actual transmission time of the time information, the trigger time of the time information may be before the actual transmission time of the time information, and the time interval between the trigger time of the time information and the actual transmission time of the time information may be small. For example, the time interval between the trigger time of the time information and the actual transmission time of the time information may be less than 1 millisecond (ms). This is not limited in this application.

[0131] The time information may be point-in-time information or time period information. This is not limited in this application. The remaining delay budget of the data is the remaining delay budget of the data starting from the time of transmission of the time information or the remaining delay budget of the data starting from the time of generation of the time information. For example, the time of data acquisition is at the 3rd millisecond, the delay budget of the data is 20 ms, the time of transmission of the time information is at the 8th millisecond, and the time interval between the time of data acquisition and the time of transmission of the time information is 5 ms. This means that the data has waited for 5 ms. In other words, the remaining delay budget of the data at the time of transmission of the time information is 15 ms. Alternatively, when the transmission delay of the time information is considered, if the transmission delay of the time information is 1 ms, the remaining delay budget of the data that exists when the time information is received is 15 ms - 1 ms = 14 ms.

[0132] For example, the time information is generated based on the time of data acquisition. The time information may indicate the time of data acquisition. For example, the time information is the time of data acquisition. Specifically, the time of data acquisition may be the number of the time element or the specific minutes and seconds on a specific day of a specific month of a specific year. This is not limited in this application. The time information may be carried by enhanced-SR information or enhanced-BSR information. This is also not limited in this application.

[0133] For example, the time information is generated based on the time interval between the time of data acquisition and the time of transmission of the time information. The time information may indicate the time interval between the time of data acquisition and the time of transmission of the time information. For example, the time information is the time interval between the time of data acquisition and the time of transmission of the time information.

[0134] The time interval can be represented in two formats. Format #1: The time interval is measured by the number of time elements. For example, the time interval is the number of time elements. In other words, the time interval between the data acquisition time and the time information transmission time can be understood as the number of time elements between the data acquisition time and the time information transmission time. Format #2: The time interval is measured by time units. For example, the time interval is the number of time units. In other words, the time interval between the data acquisition time and the time information transmission time can be understood as the number of time units between the data acquisition time and the time information transmission time. In this application, the time element may be a slot, a frame, a sub-frame, or a time domain symbol, etc., and the time unit may be a second (s), ms, or microsecond (μs), etc. This is not limited in this application. The time intervals in the following description are represented and understood in a similar way. The details will not be described again in the following description.

[0135] For example, when the enhanced-SR information includes the time information corresponding to the data, the time information can be the time interval between the data acquisition time and the enhanced-SR information transmission time.

[0136] For example, when the enhanced-BSR information includes the time information corresponding to the data, the time information can be the time interval between the data acquisition time and the enhanced-BSR information transmission time.

[0137] For example, the time information is generated based on the time interval between the data acquisition time and the scheduling request transmission time. The time information can indicate the time interval between the data acquisition time and the scheduling request transmission time. For example, the time information is the time interval between the data acquisition time and the scheduling request transmission time.

[0138] For example, when the enhanced-BSR information includes the time information corresponding to the data, the time information can be the time interval between the data acquisition time and the scheduling request transmission time.

[0139] When time information is generated based on the time interval between the data acquisition time and the transmission time of the scheduling request, the first device may determine the time interval between the data acquisition time and the transmission time of the scheduling request based on the time information. In addition, the first device may determine the time interval between the time when the scheduling request is transmitted and the time when the enhanced-BSR information is transmitted. Therefore, the first device may determine the data acquisition time with reference to the time when the enhanced-BSR information is received.

[0140] For example, the first device may determine that the time interval between the data acquisition time and the transmission time of the scheduling request is 3 slots based on the time information in the enhanced-BSR information. In addition, the first device may determine that the time interval between the scheduling request and the enhanced-BSR information is 5 slots. If the first device receives the enhanced-BSR information in slot #9, the first device may determine that the data acquisition time is at the time of slot #1.

[0141] It should be understood that the aforementioned enhanced-SR information and enhanced-BSR information are names for simplicity of explanation, and the message containing the time information corresponding to the data may have another name. This is not limited in this application.

[0142] In a possible implementation, the enhanced-SR information may be included in the UCI, and the enhanced-BSR information may be included in the MAC CE.

[0143] In a TDD system, it is further to be understood that the number and arrangement order of uplink time elements (e.g., slots) and downlink time elements (e.g., slots) can be preconfigured. Therefore, before transmitting the time information, the second device can determine the transmission time of the time information, or before transmitting the scheduling request, the second device can determine the transmission time of the scheduling request. As shown in FIG. 3, when the TDD slot configuration is DDDSU, the acquisition time of the data is the end time of the first uplink slot. The second device may determine to transmit the time information in the next uplink slot, or the second device may determine to transmit the scheduling request in the next uplink slot.

[0144] For example, the time information is generated based on the remaining delay budget of the data, or the difference between the delay budget of the data and the remaining delay budget of the data. The time information can indicate the remaining delay budget of the data, or the difference between the delay budget of the data and the remaining delay budget of the data. For example, the time information is the remaining delay budget of the data, or the time information is the difference between the delay budget of the data and the remaining delay budget of the data.

[0145] Assuming that the delay budget of the data is 20 ms, the second device can determine the transmission time of the time information and can further determine the remaining delay budget of the data that exists when the time information is transmitted. The difference between the delay budget of the data and the remaining delay budget of the data can be understood as the time interval between the acquisition time of the data and the transmission time of the time information. For example, when the time interval between the acquisition time and the transmission time of the time information is 5 ms, the remaining delay budget that exists when the time information is transmitted is 20 ms - 5 ms = 15 ms, that is, the time information can indicate 15 ms.

[0146] In a possible implementation, the aforementioned time information corresponding to the data is carried on the PUCCH or PUSCH.

[0147] For example, UCI is carried on PUCCH. When time information corresponding to data is included in UCI, the time information corresponding to the data may be carried in PUCCH format 0, and the value of the sequence cyclic shift of PUCCH format 0 corresponding to the time information is any one of 2, 5, 8, and 11.

[0148] For example, UCI is carried on PUCCH. When time information corresponding to data is included in UCI, the time information corresponding to the data may be carried in PUCCH format 1, the time information includes 2 bits, and the modulation method corresponding to the time information is quadrature phase shift keying (QPSK).

[0149] For example, MAC CE is carried on PUSCH. When time information corresponding to data is included in MAC CE, MAC CE includes logical channel identification information or logical channel group identification information. In addition, MAC CE may further include buffer size information. The buffer size information may indicate the size of the data for which transmission has not been completed so that the first device continues to schedule the data.

[0150] Optionally, method 400 further includes the following steps.

[0151] S411: The first device transmits second configuration information, and the second configuration information is used to constitute at least one value, and the time information indicates one of the at least one value. Correspondingly, the second device receives the second configuration information.

[0152] Optionally, RRC signaling includes the second configuration information.

[0153] In a possible implementation, the SchedulingRequestToAddMod information element includes the second configuration information, and the second configuration information is used to constitute at least one value.

[0154] For example, the second configuration information is the parameter DataArrival-to-SR-DelayList. The parameter is used to constitute at least one value, and each value may represent one type of time information. The name DataArrival-to-SR-DelayList here is just an example. It is not limited in this application.

[0155] The number of values constituted using DataArrival-to-SR-DelayList and the value range of each value may be predefined. The following is an example of DataArrival-to-SR-DelayList predefinition. DataArrival-to-SR-DelayList SEQUENCE(SIZE(1..4))OF INTEGER(0..10) }

[0156] This example shows that the parameter DataArrival-to-SR-DelayList can be used to constitute at least one value and at most four values. The range of each value is from 0 to 10. In addition to the aforementioned example, DataArrival-to-SR-DelayList may alternatively be used to constitute other numbers and ranges of values. The specific number of values constituted using DataArrival-to-SR-DelayList and the value range of each value are not limited in this application.

[0157] In a possible implementation, when N values are constituted using the second configuration information, the number of bits included in the time information corresponding to the data is ceil(log2(N)), where ceil represents the ceiling function.

[0158] Example #1: The DataArrival-to-SR-DelayList is used to constitute four values, and the range of each value is from 0 to 10 inclusive. Assume the four values are 1, 4, 7, and 10. The time information corresponding to the data includes 2-bit information. For example, the time information corresponding to the data is the number of slots between the time when the data is acquired and the time when the time information is transmitted. The values and meanings of the bit information indicating the time information corresponding to the data are shown in Table 5.

[0159] [Table 5]

[0160] In Example #1, when the time information corresponding to the data is "01", it indicates that the number of slots between the time when the data is acquired and the time when the time information is transmitted is 4. The first device configures the transmission resources for the data with reference to the time information.

[0161] Example #2: The DataArrival-to-SR-DelayList is used to constitute four values, and the range of each value is from 0 to 10 inclusive. Assume the four values are 1, 4, 7, and 10. The time information corresponding to the data includes 2-bit information. For example, the time information corresponding to the data is the number of slots between the time when the data is acquired and the time when the time information is transmitted. The values and meanings of the bit information indicating the time information corresponding to the data are shown in Table 6.

[0162] [Table 6]

[0163] In Example #2, when the time information corresponding to the data is "01", it indicates that the number of slots between the data acquisition time and the time information transmission time is greater than 1 and less than or equal to 4. The first device may determine that the number of slots between the data acquisition time and the time information transmission time is 1, 4, or the average of 1 and 4. Alternatively, the first device may have another processing method. This is not limited in this application. The first device may configure the transmission resource for the data with reference to the time information.

[0164] The values and meanings of the bit information in Tables 5 and 6 are merely examples. This is not limited in this application. The time information corresponding to the data may alternatively be another possibility mentioned in S420. In another possibility, the values and meanings of the bit information corresponding to the time information may be the same as those shown in Tables 5 and 6. Examples are not enumerated one by one here.

[0165] Example #3: DataArrival-to-SR-DelayList is used to constitute four values, and the range of each value is from 0 to 1. Assume the four values are 1 / 8, 3 / 8, 5 / 8, and 7 / 8. The time information corresponding to the data includes 2-bit information. For example, the time information corresponding to the data is the ratio occupied by the time interval between the data acquisition time and the time information transmission time in the PDB. The values and meanings of the bit information indicating the time information corresponding to the data are shown in Table 7.

[0166] [Table 7]

[0167] In Example #3, when the time information corresponding to the data is "01", it indicates that the time interval between the data acquisition time and the time information transmission time occupies 3 / 8 of the PDB. Assuming the PDB is 8 ms, the first device may determine that the time interval between the data acquisition time and the time information transmission time is 3 ms. The first device configures the transmission resource for the data with reference to the time information.

[0168] Example #4: The DataArrival-to-SR-DelayList is used to constitute four values, and the range of each value is from 0 or more to 1 or less. It is assumed that the four values are 1 / 8, 3 / 8, 5 / 8, and 7 / 8. The time information corresponding to the data includes 2-bit information. For example, the time information corresponding to the data is the ratio occupied by the time interval between the acquisition time point of the data and the transmission time point of the time information in the PDB. The values and meanings of the bit information indicating the time information corresponding to the data are shown in Table 8.

[0169] [Table 8]

[0170] In Example #4, when the time information corresponding to the data is "01", it indicates that the time interval between the acquisition time point of the data and the transmission time point of the time information is greater than 1 / 8 of the PDB and less than or equal to 3 / 8 of the PDB. Assuming that the PDB is 8 ms, the first device may determine that the time interval between the acquisition time point of the data and the transmission time point of the time information is 1 ms, 3 ms, or the average of 1 ms and 3 ms, that is, 2 ms. Alternatively, the first device may have another processing method. This is not limited in this application. The first device configures the transmission resources for the data with reference to the time information.

[0171] The values and meanings in Tables 7 and 8 are only examples and are not limited in this application. Alternatively, the time information corresponding to the data may be another possibility mentioned in S420 (for example, the time information corresponding to the data is the ratio occupied by the time interval between the data acquisition time and the scheduling request transmission time in the data delay budget, the time information corresponding to the data is the ratio occupied by the remaining delay budget of the data in the data delay budget, or the time information corresponding to the data is the ratio occupied by the difference between the data delay budget and the remaining delay budget in the data delay budget). In another possibility, the values and meanings of the bit information corresponding to the time information may be the same as those shown in Tables 7 and 8. Examples are not enumerated one by one here.

[0172] For example, the time information corresponding to the data includes 2 bits, and the correspondence between the value of the bit information corresponding to the time information corresponding to the data and the value of the sequence cyclic shift is shown in Table 9.

[0173]

Table 9

[0174] For example, when the value of the bit information of the time information corresponding to the data is {0, 1}, the value of the sequence cyclic shift of PUCCH format 0 corresponding to the time information is 5. The first device may interpret the time information corresponding to the data based on m CS = 5.

[0175] It should be understood that the foregoing values of the bit information and the foregoing values of the sequence cyclic shift are only examples, and the correspondence between the value of the bit information and the value of the sequence cyclic shift is also only an example. This is not limited in this application.

[0176] In a solution parallel to S411, the first configuration information is used to constitute at least two values, and the time information indicates one of the at least two values. Additionally, the at least two values can be used to constitute the transmission of the time information corresponding to the data.

[0177] Specifically, for how the first configuration information is used to constitute at least two values, how the second device transmits time information based on the at least two values, and other related content, refer to the relevant description of S411. Details will not be described again.

[0178] Optionally, method 400 further includes the following steps.

[0179] S430: The first device transmits scheduling information, and the scheduling information is used to schedule data. Correspondingly, the second device receives the scheduling information.

[0180] For example, the scheduling information can be carried on the PDCCH. For example, the scheduling information is transmitted to the terminal device using DCI format 0_0 or 0_1.

[0181] For example, the first device generates scheduling information based on the time information corresponding to the data. The scheduling information includes PUSCH resource information.

[0182] In a possible implementation, the scheduling request and the time information corresponding to the data may be transmitted with the same information, or the scheduling request may be transmitted separately.

[0183] If the scheduling information has not been received, the second device may continue to transmit the scheduling request.

[0184] Optionally, method 400 further includes the following steps.

[0185] S440: The second device transmits data. Correspondingly, the first device receives data.

[0186] For example, the data is carried on a PUSCH resource indicated by PUSCH resource information in the scheduling information. The second device transmits data on the PUSCH resource allocated by the first device. The data includes BSR information, and the BSR information is used to notify the first device of the amount of data that still needs to be transmitted. If the BSR is greater than 0, the second device continues to configure a transmission resource for the second device based on the time information corresponding to the data, and then the second device continues to perform the transmission of the remaining data on the configured transmission resource.

[0187] According to method 400, the first device may determine the acquisition time of the data so that the data transmission can be completed within the data delay budget. Therefore, the communication performance is improved.

[0188] The dashed-line steps in the foregoing flowchart are optional steps, and the order of the steps is determined based on the internal logic of the method. The sequence numbers shown in the foregoing flowchart are merely examples and do not limit the order of the steps of this application.
