[Technical Field]

[0001] This application claims priority to Chinese Patent Application No. 202210782736.3, titled "Data Transmission Method and Apparatus," filed with the China National Intellectual Property Administration on 5 July 2022, which is incorporated herein by reference in its entirety.

[0002] The embodiments of this application relate to the field of communications, and more specifically, to data transmission methods and apparatus. [Background technology]

[0003] With the advancement of communications, fifth-generation (5G) communication systems are gradually penetrating certain multimedia services that require high real-time performance and large data capacity, such as video transmission, cloud gaming (CG), and extended reality (XR). Multimedia services have stringent requirements regarding data transmission latency. Therefore, how to meet data transmission latency requirements in the communication process has become a matter that needs to be considered. [Overview of the Initiative]

[0004] Embodiments of this application provide a communication method and communication apparatus for completing data transmission within a data delay budget. Therefore, communication performance is improved. [Means for solving the problem]

[0005] According to a first aspect, a communication method is provided. This method may be performed by a first device. The first device may be a network device or a terminal device, a chip or circuit within a terminal device, a chip or circuit within a network device, a logic module or software capable of performing all or part of the functions of a network device, or a logic module or software capable of performing all or part of the functions of a terminal device. This is not limited to the present application. The method includes the steps of receiving first configuration information and transmitting time information corresponding to data based on the first configuration information, wherein the time information is generated based on the time of data acquisition or the remaining delay budget of the data.

[0006] In possible embodiments, time information is used for scheduling and transmitting data, and scheduling and transmitting data can be understood as configuring resources for data so that data transmission is performed on the configured resources.

[0007] For example, time information directly or indirectly indicates the time when the data was acquired, or directly or indirectly indicates the remaining delay budget for the data.

[0008] According to the aforementioned solution, when the first device is configured to transmit time information corresponding to the data, the first device transmits time information corresponding to the data, thereby allowing the data scheduler to determine the remaining delay budget for the data. For example, the time information relates to the time of data acquisition. In this case, after receiving the time information, the data scheduler can determine the remaining delay budget for the data based on the data delay budget and the time information. Alternatively, the time information relates to the remaining delay budget for the data. In this case, after receiving the time information, the data scheduler can determine the remaining delay budget for the data based on the time information. In this way, data transmission is completed within the data delay budget. Therefore, communication performance is improved.

[0009] In relation to the first aspect, in some embodiments of the first aspect, when a media access control entity or a packet data convergence protocol entity acquires data, time information corresponding to the data is transmitted based on the first configuration information.

The terminal device may also be a device that provides voice and / or data connectivity to a user, a handheld device with wireless connectivity, or another processing device connected to a wireless modem.

[0076] In embodiments of this application, terminal devices may also be called terminals, access terminals, subscriber units, user equipment (UE), subscriber stations, mobile stations, remote stations, remote terminals, mobile devices, user terminals, wireless communication devices, user agents, or user equipment. A terminal device is a device that includes wireless communication capabilities (providing voice / data connectivity to a user), such as a handheld device or in-vehicle device with wireless connectivity. The terminals in the embodiments of this application include mobile phones, tablet computers, computers with wireless transceiver functionality, trains, airplanes, mobile internet devices (MIDs), virtual reality (VR) terminals, augmented reality (AR) terminals, wireless terminals for industrial control (e.g., robots), wireless terminals for the Internet of Vehicles (e.g., in-vehicle devices, vehicle devices, in-vehicle modules, or vehicles), wireless terminals for self-driving, wireless terminals for remote medical care, wireless terminals for smart grids, wireless terminals for transportation safety, wireless terminals for smart cities, wireless terminals for smart homes, cellular phones, cordless phones, session initiation protocol (SIP) phones, wireless local loop (WLL) stations, and personal digital information terminals (PDIs).

[0077] Wearable devices, also known as wearable intelligent devices, are a general term for wearable devices such as glasses, gloves, watches, clothing, and shoes, developed by applying wearable technology to the intelligent design of everyday wear. Wearable devices are portable devices that are worn directly on the body or integrated into the user's clothing or accessories. Wearable devices are hardware devices that perform powerful functions through software support, data exchange, and cloud interaction. In a broader sense, intelligent wearable devices include full-featured large devices that can perform full or partial functions without relying on a smartphone, such as smartwatches or smart glasses, and devices specialized for only one type of application function that need to be used with other devices such as smartphones, such as various smart bands or smart jewelry used to monitor physical signs.

[0078] A network device may also be a device within a wireless network. For example, a network device may be a device located in a radio access network that provides wireless communication capabilities to terminal devices. For instance, a network device may be a radio access network (RAN) node that connects terminal devices to a wireless network, and may also be called an access network device.

[0079] Network devices include, but are not limited to, evolved NodeB (eNB), radio network controller (RNC), NodeB (NB), base station controller (BSC), base transceiver station (BTS), home base station (e.g., home evolved NodeB, HeNB or home NodeB, HNB), baseband unit (BBU), servers, wearable devices, in-vehicle devices, Wi-Fi system access points (AP), wireless relay nodes, wireless backhaul nodes, transmission points (TP), or transmission and reception points (TRP). The network device may be a gNB or transmit point (TRP or TP) in a 5G system, such as an NR system, or one antenna panel or group of antenna panels (including multiple antenna panels) of a base station in a 5G system; or the network device may be a network node constituting a gNB or transmit point, such as a baseband unit (BBU) or distributed unit (DU). The base station may be a macro base station, micro base station, pico base station, small cell, relay station, or balloon station, etc. It can be understood that all or part of the functions of the network device in this application may be implemented using software functions running on hardware, or using instantiated virtualization functions 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 of the functions of the gNB, and the DU performs some of the functions of the gNB. For example, the CU is responsible for processing non-real-time protocols and services and performs the functions of the radio resource control (RRC) layer and the packet data convergence protocol (PDCP) layer. The DU is responsible for processing physical layer protocols and real-time services and performs 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 the active antenna. RRC layer information is generated by the CU and ultimately encapsulated in PHY layer information at the DU's PHY layer, or converted from PHY layer information. Therefore, in this architecture, higher-layer signaling, such as RRC layer signaling, may be considered to be transmitted by the DU, or by both the DU and the AAU. It can be understood that a network device may be a device comprising one or more of the CU nodes, DU nodes, and AAU nodes. In addition, a CU may be classified as a network device in an access network (RAN), or a CU may be classified as a network device in a core network (CN). This is not limited to the present application.

[0081] Today, with the continuous advancement and improvement of technologies related to multimedia services (e.g., CG and XR services), network latency requirements are becoming more stringent in order to enhance immersion. For example, in remote control systems, the sampling rate of haptic information should not be less than 1 kHz to ensure high fidelity of touch and remote control, and the transmission latency requirement for each sample should reach 5 ms. Therefore, in some multimedia services where transmission latency requirements are becoming increasingly stringent, how to complete data transmission within the latency budget is an issue that needs to be considered, and the data latency budget can be determined based on the transmission latency requirements of the service.

[0082] Figure 2 is an interaction flowchart of a data scheduling method according to one embodiment of the present application. In Figure 2, an example is used in which a network device and a terminal device are used as the entities of the interaction to illustrate the method. However, the entities of the interaction are not limited in this application. For example, the network device in Figure 2 may be a chip, chip system, or processor that supports the network device when carrying out the method, or a logic module or software that can perform all or some of the functions of the network device. The terminal device in Figure 2 may be a chip, chip system, or processor that supports the terminal device when carrying out the method, or a logic module or software that can perform all or some of the functions of the terminal device. The method 200 shown in Figure 2 includes the following steps.

[0083] S210: A terminal device sends a scheduling request (SR), which is used to request scheduling resources for data. In response, a network device receives the scheduling request.

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

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

[0086] For example, scheduling requests may be carried in PUCCH format 0 or PUCCH format 1. PUCCH format 0 may further be used to transmit ACK / NACK (acknowledgment / negation) feedback for hybrid automatic repeat requests (HARQ). The information transmitted in PUCCH format 0 contains one or two bits (corresponding to the case where a scheduled physical downlink shared channel (PDSCH) contains 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 possible embodiments, PUCCH format 0 is generated based on a ZC (Zadoff-Chu) sequence. The information carried in the ZC sequence may be indicated by the final value of the sequence cycle shift. The final value of the sequence cycle shift is the value m of the sequence cycle shift. CSIt can be decided based on this.

[0088] For example, when the information being transmitted is HARQ-ACK information, the m corresponding to the HARQ-ACK information CS This can be determined using the correspondence between HARQ-ACK information and the sequence cyclic shift in 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 in PUCCH format 0 is shown in Table 1, and the m corresponding to the HARQ-ACK value CS This 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 in PUCCH format 0 is shown in Table 2, and the m corresponding to the HARQ-ACK value CS This 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 It is determined that =3, and the final value of the sequence cyclic shift in PUCCH format 0 that carries the HARQ-ACK value is m CS Further decisions can be made based on =3.

[0092] When HARQ-ACK information and scheduling requests are multiplexed, in other words, when scheduling requests and HARQ-ACK information are transmitted simultaneously, the scheduling request is a positive request (specifically, it notifies network devices that there is data to be transmitted). Terminal devices may also indicate the HARQ-ACK information and positive scheduling requests using a cyclic shift method. For example, when the transmitted HARQ-ACK information and positive scheduling request consist of 1 bit, the correspondence between the values ​​of the HARQ-ACK information bits and positive scheduling requests and the sequence cyclic shift in PUCCH format 0 is shown in Table 3. When the transmitted HARQ-ACK information bits and positive scheduling requests consist of 2 bits, the correspondence between the values ​​of the HARQ-ACK information bits and positive scheduling requests and the sequence cyclic shift in 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 information bits. In other words, when the sequence cycle shift values ​​are the values ​​in Tables 3 and 4, the HARQ-ACK value indicates HARQ-ACK information and an aggressive scheduling request. The resources for sending HARQ-ACK information, or HARQ-ACK information and an aggressive scheduling request, are provided by network devices. Therefore, m CS When = 3 or 9, the network device may determine, based on Table 2, whether to interpret the HARQ-ACK information indicated by 2 bits, or based on Table 3, whether to interpret the HARQ-ACK information and the aggressive scheduling request indicated by 1 bit.

[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. In response, the network device receives data.

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

[0104] For example, scheduling information includes PUSCH resource information, and the terminal device transmits data using the PUSCH resource assigned by the network device. The data includes buffer status report (BSR) information, which is used to inform the network device of the amount of data that still needs to be transmitted. If the BSR is greater than 0, the network device may continue scheduling for the terminal device. Specifically, the network device continues to send scheduling information to the terminal device via PDCCH, and the terminal device then continues to transmit data using the PUSCH resource indicated by the scheduling information.

[0105] In a time division duplex (TDD) system, the ratio of uplink slots to downlink slots and the sequence of uplink and downlink slots can be preconfigured. While network devices can only receive scheduling requests on uplink slots, the time when terminal devices acquire data may be earlier than the time corresponding to the slot. Consequently, in the data scheduling solution of method 200, network devices cannot know the exact time when terminal devices acquire data.

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

[0107] An example of a TDD slot configuration where DDDSU is used for explanation. The data delay budget is 15ms, in other words, it is assumed that the data is invalid after the fourth uplink slot shown in Figure 3 has finished. Therefore, data transmission must be completed within the delay budget. If the end of the second uplink slot to which the scheduling request is sent is used as the data acquisition time, the network device will complete the scheduling and transmission of the data within 15ms after the second uplink slot, based on the data delay budget. However, the actual data acquisition time is the end of the first uplink slot. As a result, data transmitted after the fourth uplink slot will be invalid.

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

[0109] The data delay budget can also be understood as the validity period 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 transmission process of data packets between a user plane function (UPF) network element and a terminal device. If the transmission delay of data packets between the UPF and the terminal device exceeds the PDB, the data packets may be wasted on the receiving end. In this embodiment of the present application, the data delay budget may be the maximum transmission delay that can be tolerated in the transmission process of data between a network device (e.g., a base station) and a terminal device, i.e., an access network (AN) PDB. Alternatively, the data delay budget may be the maximum transmission delay that can be tolerated in the transmission process of data between a network device (e.g., a base station) and another network device (e.g., another base station). Alternatively, the data delay budget may be the maximum transmission delay that can be tolerated in the transmission process of data between a terminal device and another terminal device.

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

[0111] In consideration of the aforementioned problems, one embodiment of this application provides a communication method for completing data transmission within a data delay budget. Thus, communication performance is improved.

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

[0113] Optionally, in S410, the first device transmits first configuration information, which is used to configure the transmission of time information corresponding to the data. In response, 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 and second devices 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 implements listed in the foregoing are merely examples and are not limited in this application. For example, the first device may be a chip, chip system, or processor that supports a network device or terminal device when carrying out the method, or a logic module or software that can perform all or part of the functions of a network device or terminal device. The second device may be a chip, chip system, or processor that supports a terminal device or network device when carrying out the method, or a logic module or software that can perform all or part of the functions of a terminal device or network device.

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

[0117] For example, if the data has a delay budget, and the data transmission delay exceeds the delay budget, the data becomes invalid. The second device may transmit time information corresponding to the data to the first device when the second device receives first configuration information, and the first configuration information is used to configure the second device to transmit time information corresponding to the data being acquired. The second device cannot transmit time information corresponding to the data to the first device if 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 being acquired.

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

[0119] For example, the first configuration information is the configuration information for a logical channel, and the configuration information includes an 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 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 the second device not to transmit time information corresponding to data. The names of the fields mentioned above are examples only and are not limited to those in this application.

[0120] The following is an example of a configuration that includes 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 a 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 to the present application.

[0122] In the example above, it should be understood that the enhanced-BSR field is configuration information for enhanced-BSR information, and that enhanced-BSR information may include time information corresponding to the data. Specifically, whether 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 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 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. Enhanced-BSR information that does not include time information corresponding to the data may be understood as BSR. The enhanced-BSR information described above is an example of the name of information that includes time information corresponding to the data. This is not limited to this application.

[0123] For example, the first configuration information is the enhanced-SR field within the 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 the second device not to transmit time information corresponding to the data. The field names mentioned above are examples only and are not limited to those in this application.

[0124] The following is an example of a configuration that includes 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 example above, it should be understood that the enhanced-SR field is configuration information for enhanced-SR information, and that enhanced-SR information may include time information corresponding to data. Specifically, whether enhanced-SR information includes time information corresponding to data is configured using the enhanced-SR field. When the enhanced-SR field is used to configure that enhanced-SR information includes time information corresponding to data, for example, when the enhanced-SR field is set to true, the enhanced-SR information includes time information corresponding to data. When the enhanced-SR field is used to configure that enhanced-SR information does not include time information corresponding to data, for example, when the enhanced-SR field is set to false, the enhanced-SR information does not include time information corresponding to data. Enhanced-SR information that does not include time information corresponding to data may be understood as a scheduling request. The enhanced-SR information described above is an example of a name for information that includes time information corresponding to data. This is not limited to this application.

[0126] S420: The second device transmits time information corresponding to the data, which is generated based on the time the data was acquired or the remaining delay budget of the data. In response, the first device receives the time information corresponding to the data.

[0127] In possible embodiments, after receiving first configuration information (which 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 element (MAC CE) includes time information corresponding to the data.

[0129] In possible embodiments, the time information is one of the following: the time interval between the time of data acquisition and the time of time information transmission, or the time interval between the time of data acquisition and the time of scheduling request transmission, and the scheduling request is generated based on one of the following: the time interval used to request scheduling resources for the data, or the difference between the data delay budget and the remaining data delay budget.

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

[0131] Time information may be point-in-time information or time-duration information. This is not limited to this application. The remaining delay budget for data is the remaining delay budget for data starting from the time the time information is transmitted, or the remaining delay budget for data starting from the time the time information is generated. For example, the data acquisition time is 3ms, the data delay budget is 20ms, the time information transmission time is 8ms, and the time interval between the data acquisition time and the time information transmission time is 5ms. This means that the data waited for 5ms, or in other words, the remaining delay budget for data at the time information transmission time is 15ms. Alternatively, when a transmission delay for time information is possible, if the transmission delay for time information is 1ms, the remaining delay budget for data that exists when the time information is received is 15ms - 1ms = 14ms.

[0132] For example, time information is generated based on the time the data was acquired. Time information may indicate the time the data was acquired. For example, time information is the time the data was acquired. Specifically, the time the data was acquired may be a time element number, or it may be a specific minute and second on a specific day in a specific month of a specific year. This is not limited in this application. Time information may be carried in enhanced-SR information or enhanced-BSR information. This is also not limited in this application.

[0133] For example, time information is generated based on the time interval between the time the data is acquired and the time the time information is transmitted. Time information can indicate the time interval between the time the data is acquired and the time the time information is transmitted. For example, time information is the time interval between the time the data is acquired and the time the time information is transmitted.

[0134] Time intervals can be expressed in two forms. Form #1: Time intervals are measured by the number of time elements. For example, a time interval is the number of time elements. In other words, the time interval between the time of data acquisition and the time of time information transmission can be understood as the number of time elements between the time of data acquisition and the time information transmission. Form #2: Time intervals are measured by time units. For example, a time interval is the number of time units. In other words, the time interval between the time of data acquisition and the time information transmission can be understood as the number of time units between the time of data acquisition and the time information transmission. In this application, time elements may be slots, frames, subframes, or time-domain symbols, and time units may be seconds (s), milliseconds (ms), or microseconds (μs), etc. This is not limited in this application. Time intervals in the following description are expressed and understood in a similar manner. Details are again not described in the following description.

[0135] For example, when enhanced-SR information includes time information corresponding to the data, the time information may be the time interval between the time the data is acquired and the time the enhanced-SR information is transmitted.

[0136] For example, when enhanced-BSR information includes time information corresponding to the data, the time information may be the time interval between the time the data is acquired and the time the enhanced-BSR information is transmitted.

[0137] For example, time information is generated based on the time interval between the time the data is acquired and the time the scheduling request is sent. Time information can indicate the time interval between the time the data is acquired and the time the scheduling request is sent. For example, time information is the time interval between the time the data is acquired and the time the scheduling request is sent.

[0138] For example, when enhanced-BSR information includes time information corresponding to the data, the time information may be the time interval between the time the data is acquired and the time the scheduling request is sent.

[0139] When time information is generated based on the time interval between the data acquisition time and the scheduling request transmission time, the first device can determine the time interval between the data acquisition time and the scheduling request transmission time based on the time information. In addition, the first device can determine the time interval between the time the scheduling request was transmitted and the time the enhanced-BSR information was transmitted. Therefore, the first device can determine the data acquisition time by referring to the time the enhanced-BSR information was received.

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

[0141] The aforementioned enhanced-SR information and enhanced-BSR information are names used for simplicity of explanation, and it should be understood that messages containing time information corresponding to the data may have different names. This is not limited to the present application.

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

[0143] It should be further understood that in a TDD system, 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 time information, the second device may determine when to transmit the time information, or before transmitting a scheduling request, the second device may determine when to transmit a scheduling request. As shown in Figure 3, when the TDD slot configuration is DDDSU, the data acquisition time is the end of the first uplink slot. The second device may decide to transmit time information in the next uplink slot, or the second device may decide to transmit a scheduling request in the next uplink slot.

[0144] For example, time information is generated based on the remaining delay budget of the data, or the difference between the data's delay budget and the remaining delay budget of the data. Time information may indicate the remaining delay budget of the data, or it may indicate the difference between the data's delay budget and the remaining delay budget of the data. For example, time information is the remaining delay budget of the data, or time information is the difference between the data's delay budget and the remaining delay budget of the data.

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

[0146] In possible embodiments, the aforementioned time information corresponding to the data is transported via PUCCH or PUSCH.

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

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

[0149] For example, a MAC CE is transported by PUSCH. When time information corresponding to the data is included in the MAC CE, the MAC CE includes logical channel identification information or logical channel group identification information. In addition, the MAC CE may further include buffer size information. The buffer size information may indicate the size of data whose 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, which is used to construct at least one value, and the time information indicates at least one of the values. In response, the second device receives the second configuration information.

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

[0153] In a possible embodiment, the SchedulingRequestToAddMod information element includes second configuration information, which is used to configure at least one value.

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

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

[0156] This example demonstrates that the parameter DataArrival-to-SR-DelayList can be used to constitute a minimum of one value and a maximum of four values, each in the range of 0 to 10. In addition to the example above, DataArrival-to-SR-DelayList may be used to constitute other numbers and ranges of values. The specific number of values ​​and the range of values ​​for each value that can be constituted using DataArrival-to-SR-DelayList are not limited in this application.

[0157] In possible embodiments, when N values ​​are constructed using second configuration information, the number of bits in the time information corresponding to the data is ceil(log2(N)), where ceil represents a rounding up function.

[0158] Example #1: DataArrival-to-SR-DelayList is used to construct four values, each in the range of 0 to 10. The four values ​​are assumed to be 1, 4, 7, and 10. The time information corresponding to the data contains 2 bits of information. For example, the time information corresponding to the data is the number of slots between the time the data is acquired and the time 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 there are 4 slots between the time the data is acquired and the time the time information is transmitted. The first device uses the time information to configure the transmission resources for the data.

[0161] Example #2: DataArrival-to-SR-DelayList is used to construct four values, each in the range of 0 to 10. The four values ​​are assumed to be 1, 4, 7, and 10. The time information corresponding to the data contains 2 bits of information. For example, the time information corresponding to the data is the number of slots between the time the data is acquired and the time 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 an average of 1 and 4. Alternatively, the first device may have a different processing method, which is not limited in this application. The first device may configure a transmission resource for the data by referring to the time information.

[0164] The values ​​and meanings of the bit information in Tables 5 and 6 are examples only and are not limited in this application. The time information corresponding to the data may be, or, as mentioned in S420, another possibility. In the other 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 listed one by one here.

[0165] Example #3: DataArrival-to-SR-DelayList is used to construct four values, each in the range of 0 to 1. The four values ​​are assumed to be 1 / 8, 3 / 8, 5 / 8, and 7 / 8. The time information corresponding to the data includes two bits of information. For example, the time information corresponding to the data is the percentage 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 8ms, the first device can determine that the time interval between the data acquisition time and the time information transmission time is 3ms. The first device then uses the time information to configure the transmission resources for the data.

[0168] Example #4: DataArrival-to-SR-DelayList is used to construct four values, each in the range of 0 to 1. The four values ​​are assumed to be 1 / 8, 3 / 8, 5 / 8, and 7 / 8. The time information corresponding to the data includes 2 bits of information. For example, the time information corresponding to the data is the percentage 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 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 data acquisition time and the time information transmission time is greater than 1 / 8 of the PDB and less than or equal to 3 / 8 of the PDB. Assuming the PDB is 8ms, the first device may determine that the time interval between the data acquisition time and the time information transmission time is 1ms, 3ms, or the average of 1ms and 3ms, i.e., 2ms. Alternatively, the first device may have a different processing method, which is not limited in this application. The first device configures a transmission resource for the data by referring to the time information.

[0171] The values ​​and meanings in Tables 7 and 8 are merely examples and are not limited to this application. Alternatively, the time information corresponding to the data may be of other possibilities as mentioned in S420 (for example, the time information corresponding to the data is the proportion of the data delay budget occupied by the time interval between the time of data acquisition and the time of transmission of the scheduling request, the time information corresponding to the data is the proportion of the data delay budget occupied by the remaining data delay budget, or the time information corresponding to the data is the proportion of the data delay budget occupied by the difference between the data delay budget and the remaining delay budget). In another possibility, the values ​​and meanings of the bit information corresponding to the time information may be similar to those shown in Tables 7 and 8. Examples are not listed 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 cycle shift is shown in Table 9.

[0173] [Table 9]

[0174] For example, when the bit information value 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 is m CS Based on =5, time information corresponding to the data can be interpreted.

[0175] Please understand that the aforementioned values ​​for bit information and sequence cyclic shifts are merely examples, and the correspondence between bit information values ​​and sequence cyclic shift values ​​is also merely an example. This is not limited to the present application.

[0176] In a solution parallel to S411, the first configuration information is used to configure at least two values, and the time information indicates at least one of those two values. In addition, at least two values ​​may be used to configure the transmission of time information corresponding to the data.

[0177] Specifically, for the method by which the first configuration information is used to constitute at least two values, the method by which the second device transmits time information based on at least two values, and other related matters, please refer to the relevant description in S411. Further details will not be provided again.

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

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

[0180] For example, scheduling information can be transported via PDCCH. For instance, scheduling information is sent to a terminal device using DCI format 0_0 or 0_1.

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

[0182] In possible embodiments, 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 scheduling information has not been received, the second device may continue to send scheduling requests.

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

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

[0186] For example, data is transported on a PUSCH resource indicated by PUSCH resource information in scheduling information. The second device transmits the data on the PUSCH resource allocated by the first device. The data includes BSR information, which is used to inform 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 itself based on the time information corresponding to the data, and then the second device continues to transmit the remaining data on the configured transmission resource.

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

[0188] The dashed steps in the flowchart above 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 flowchart above are examples only and do not limit the order of the steps in this application.
