Data transmission method and device

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office of the People's Republic of China on January 31, 2024, with application number 202410138134.3 and application name "A Data Transmission Method and Device", the entire contents of which are incorporated by reference into this application. Technical Field

[0003] The present application relates to the field of wireless communication technology, and in particular to a data transmission method and device. Background Art

[0004] At present, in order to save the power consumption of the terminal, the terminal can enter the sleep state, and the wake-up signal (WUS) can be used to wake up the terminal. If the terminal does not receive the WUS, or the WUS indicates not to wake up, the terminal will remain in the sleep state. If the terminal receives the WUS indication to wake up, the terminal can wake up from the sleep state and perform data transmission. When the terminal wakes up from the sleep state to the active state to work, the uplink and downlink beams may be misaligned due to reasons such as terminal movement. In addition, due to outdated channel information, re-measurement is required, and synchronization timeout requires re-time and frequency domain synchronization. At this time, the terminal needs to re-synchronize in the time and frequency domain, and perform operations such as channel measurement and measurement feedback to align the uplink and downlink beams and obtain channel information. However, this process is lengthy and time-consuming, and the terminal cannot perform data transmission during this process, resulting in low efficiency of terminal data transmission. Summary of the Invention

[0005] The present application provides a data transmission method and apparatus for reducing the time required between waking up a terminal device and transmitting data.

[0006] In the first aspect, a data transmission method is provided. The method can be applied to the terminal side, such as the terminal or the communication module in the terminal, or the circuit or chip responsible for the communication function in the terminal (such as a modem chip, also known as a baseband chip, or a system on chip (SoC) chip or system in package (SIP) chip containing a modem core), taking the application of this method to the terminal as an example. In this method, the terminal device receives a wake-up signal, and the wake-up signal indicates wake-up from a sleep state. The terminal device responds to the wake-up signal and determines to transmit data through a first mode. The first mode indicates that data is transmitted in a progressive manner.

[0007] Based on the above solution, the terminal device can transmit data through the first mode after waking up, that is, the terminal device can also transmit data during channel measurement, measurement feedback, and time-frequency domain synchronization, thereby improving the data transmission efficiency of the terminal.

[0008] Optionally, transmitting data in a progressive manner may include increasing the amount of transmitted data and / or the bandwidth occupied by the data from small to large.

[0009] In one possible implementation, the progressive approach includes exponential growth or linear growth in the amount of data transmitted. Based on the above solution, after waking up, the terminal device may experience misalignment of uplink and downlink beams due to movement, so the terminal device can transmit a small amount of data. After completing channel measurement, measurement feedback, and time-frequency domain synchronization, the terminal device can obtain complete channel information, and the amount of data sent by the terminal device can gradually increase.

[0010] In one possible implementation, a terminal device receives first configuration information indicating a first transmission bandwidth, where the first transmission bandwidth is the maximum transmission bandwidth used for data transmission in the first mode. Based on the above solution, the network device may indicate to the terminal device the transmission bandwidth used for data transmission in the first mode via the first configuration information. Optionally, the transmission bandwidth used for data transmission in the first mode may be progressive, thereby enabling progressive data transmission.

[0011] In a possible implementation, the first configuration information further indicates a second transmission bandwidth that can be used for the nth transmission, where the second transmission bandwidth is part or all of the first transmission bandwidth, and n is an integer greater than or equal to 1.

[0012] Based on the above solution, the network device can indicate the transmission bandwidth used for the nth data transmission to the terminal device through the first configuration information, so that the transmission bandwidth can be progressive, and therefore the data volume can also be progressive.

[0013] In a possible implementation, the terminal device receives downlink control information, where the downlink control information indicates that the second transmission bandwidth is at a position of the activated transmission bandwidth, and the activated transmission bandwidth is the first transmission bandwidth.

[0014] Based on the above solution, the network device can indicate the frequency domain resources used for data to the terminal device through downlink control information.

[0015] In a possible implementation, a modulation and coding scheme (MCS) used for data is associated with the number of data streams.

[0016] Based on the above scheme, since a low number of streams in data transmission usually means poor channel quality, a low-order modulation method can be selected. Therefore, by associating the MCS used by the data with the number of data streams, the MCS can also be gradually increased when the number of data streams gradually increases.

[0017] In one possible implementation, the wake-up signal indicates a position of a timing window. The timing window is associated with at least one modulation and coding strategy. The terminal device determines to transmit data within the timing window using the first mode and the at least one modulation and coding strategy associated with the timing window.

[0018] Based on the above solution, after activation, the terminal device can perform channel measurement, measurement feedback, and time-frequency domain synchronization. Therefore, as time goes by, the terminal device can gradually obtain complete channel information. Therefore, by associating the timing window with the MCS, the MCS can be gradually increased.

[0019] In one possible implementation, a terminal device receives downlink control information, where the downlink control information indicates an antenna port, and the antenna port is used to determine the number of streams when transmitting data using a first mode. The downlink control information does not include code division multiplexing information. Alternatively, the downlink control information indicates a specified number of demodulation reference signals.

[0020] Based on the above solution, the downlink control information does not include code division multiplexing information. Alternatively, the downlink control information indicates a specified number of demodulation reference signals, which can reduce the number of bits of the downlink control information and thus reduce the overhead of the downlink control information.

[0021] In a possible implementation, the terminal device receives second configuration information, where the second configuration information indicates the size of the control resource set, and the size of the control resource set has the same change pattern as the second transmission bandwidth.

[0022] Based on the above solution, data is transmitted progressively, and downlink control information can also be transmitted progressively. Therefore, by configuring the size of the control resource set to have the same change pattern as the second transmission bandwidth, progressive transmission of downlink control information can be achieved.

[0023] In one possible implementation, a terminal device receives third configuration information, where the third configuration information indicates m control resource sets and m first transmission bandwidths. The m control resource sets correspond one-to-one to the m first transmission bandwidths, and a group of control resource sets includes one or more control resource sets. m is a positive integer.

[0024] Based on the above scheme, the network device indicates to the terminal device through the third configuration information m groups of control resource sets corresponding one-to-one to m first transmission bandwidths. When one of the m first transmission bandwidths is activated, the terminal device can blindly detect downlink control information on the control resource set corresponding to the activated first transmission bandwidth.

[0025] In one possible implementation, the terminal device sends a data response message including a measurement result of the signal carrying the data. Based on the above solution, the terminal device can feed back the measurement result to the network device and indicate the channel environment to the network device.

[0026] In a possible implementation, the response message further includes at least one of the following: indication information on whether the decoding is correct or a reference modulation and coding strategy, wherein the reference modulation and coding strategy corresponds to the measurement result.

[0027] Based on the above solution, the terminal device can indicate the reference MCS to the network device, so that the base station can determine the MCS to be used for the next transmission. Compared with the MCS adjustment solution in the related art, it is more timely and accurate.

[0028] In a possible implementation, the downlink control information further includes padding bits, where the padding bits include radio frequency channel mapping data RF map, one or more of a sensing result, a target speed, a target position, bit 0, or bit 1.

[0029] Based on the above solution, the network device can fill downlink control information of different lengths by padding bits, thereby making the length of the downlink control information consistent.

[0030] In a possible implementation, the terminal device receives fourth configuration information, where the fourth configuration information indicates an aggregation level used by a blind detection physical downlink control channel, or the fourth configuration information indicates that the aggregation level used by the blind detection physical downlink control channel corresponds to a channel quality.

[0031] Based on the above solution, the network device can indicate the aggregation level used by the blind detection physical downlink control channel to the terminal device through the fourth configuration information.

[0032] In one possible implementation, a terminal device transmits data in a second mode that is different from the first mode. A condition for switching from the first mode to the second mode is indicated by a network device or predefined. Based on the above solution, the terminal device can switch to the second mode for data transmission, thereby improving data transmission performance.

[0033] In a possible implementation manner, the condition is carried in one of downlink control information, radio resource control signal or paging message.

[0034] In one possible implementation, the condition includes one or more of the following: a measurement result of a data-carrying signal is greater than or equal to a first threshold, or a channel quality is greater than or equal to a second threshold. Based on the above solution, the terminal device can determine to switch from the first mode to the second mode for data transmission based on the condition.

[0035] In one possible implementation, the wake-up signal indicates a first duration, and after the terminal device transmits data in the first mode for the first duration, it transmits data in a second mode that is different from the first mode. Based on the above solution, the terminal device can switch to the second mode for data transmission when the first duration indicated by the wake-up signal is reached.

[0117] The technical solutions of the embodiments of the present application can be applied to New Radio (NR) systems, Long Term Evolution (LTE) systems, LTE Frequency Division Duplex (FDD) systems, LTE Time Division Duplex (TDD) systems, Worldwide Interoperability for Microwave Access (WiMAX) communication systems, and fifth generation communication systems (5G) and 5G th generation, 5G), and next-generation wireless communication systems, such as 6G, are not restricted here.

[0118] FIG1 is a schematic diagram of the architecture of a communication system 1000 used in an embodiment of the present application. As shown in FIG1 , the communication system includes a wireless access network 100. The wireless access network 100 may include at least one network device (such as 110a and / or 110b in FIG1 ) and may also include at least one terminal device (such as at least one of 120a-120j in FIG1 ). The terminal device is connected to the access network device wirelessly, and the access network device is connected to the core network device wirelessly or by wire. Terminal devices and network devices may be connected to each other by wire or by wireless. FIG1 is only a schematic diagram, and the communication system may also include other network devices, such as wireless relay devices and wireless backhaul devices, which are not shown in FIG1 .

[0119] A network device is a network-side device with wireless transceiver capabilities. A network device can be a device in a radio access network (RAN) that provides wireless communication capabilities for terminal devices, and is called a RAN device. For example, a network device can be a base station, an evolved NodeB (eNodeB), a transmission reception point (TRP), a next-generation NodeB (gNB) in a fifth-generation (5G) mobile communication system, a next-generation base station in a sixth-generation (6G) mobile communication system, a base station in a future mobile communication system, or an access node in a WiFi system. It can also be a module or unit that performs some of the functions of a base station, such as a centralized unit (CU) or a distributed unit (DU). The CU here completes the functions of the radio resource control protocol and the packet data convergence protocol (PDCP) of the base station, and can also complete the function of the service data adaptation protocol (SDAP); the DU completes the functions of the radio link control layer and the medium access control (MAC) layer of the base station, and can also complete the functions of part of the physical layer or all of the physical layer. For the specific description of the above-mentioned protocol layers, please refer to the relevant technical specifications of the 3rd Generation Partnership Project (3GPP). The network device can be a macro base station (such as 110a in Figure 1), a micro base station or an indoor station (such as 110b in Figure 1), a relay node or a donor node, etc. The embodiments of the present application do not limit the specific technology and specific device form adopted by the network device.

[0120] In another possible scenario, multiple RAN nodes collaborate to assist the terminal in achieving wireless access, and different RAN nodes implement part of the functions of the base station respectively. For example, the RAN node can be a CU, DU, CU-control plane (CP), CU-user plane (UP), or radio unit (RU). The CU and DU can be set separately, or they can be included in the same network element, such as a baseband unit (BBU). The RU can be included in a radio frequency device or radio frequency unit, such as a remote radio unit (RRU), an active antenna unit (AAU), or a remote radio head (RRH).

[0121] In different systems, CU (or CU-CP and CU-UP), DU or RU may also have different names, but those skilled in the art can understand their meanings. For example, in an open radio access network (ORAN) system, CU may also be called O-CU (open CU), DU may also be called O-DU, CU-CP may also be called O-CU-CP, CU-UP may also be called O-CU-UP, and RU may also be called O-RU. For the convenience of description, this application takes CU, CU-CP, CU-UP, DU and RU as examples for description. Any unit of CU (or CU-CP, CU-UP), DU and RU in this application can be implemented by a software module, a hardware module, or a combination of a software module and a hardware module.

[0122] A terminal device is a user-side device with wireless transceiver capabilities. A terminal device may also be referred to as user equipment (UE), a mobile station, a mobile terminal, etc. Terminal devices can be widely used in various scenarios, such as device-to-device (D2D), vehicle-to-everything (V2X) communication, machine-type communication (MTC), Internet of Things (IOT), virtual reality, augmented reality, industrial control, autonomous driving, telemedicine, smart grid, smart furniture, smart office, smart wearable, smart transportation, smart city, etc. The terminal device may be a mobile phone, a tablet computer, a computer with wireless transceiver capabilities, a wearable device, a vehicle, a drone, a helicopter, an airplane, a ship, a robot, a robotic arm, a smart home appliance, etc. The embodiments of the present application do not limit the specific technology and specific device form adopted by the terminal device.

[0123] Network devices and terminal devices can be fixed or mobile. They can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; on water; and in the air on aircraft, balloons, and satellites. The embodiments of this application do not limit the application scenarios of network devices and terminal devices.

[0124] The roles of network devices and terminal devices can be relative. For example, the helicopter or drone 120i in Figure 1 can be configured as a mobile network device. To terminal devices 120j accessing the wireless access network 100 via 120i, terminal device 120i is a network device. However, to network device 110a, 120i is a terminal device, meaning that communication between 110a and 120i occurs via a wireless air interface protocol. Of course, communication between 110a and 120i can also occur via an interface protocol between network devices. In this case, 120i is also a network device relative to 110a. Therefore, both network devices and terminal devices can be collectively referred to as communication devices. 110a and 110b in Figure 1 can be referred to as communication devices with network device functionality, while 120a-120j in Figure 1 can be referred to as communication devices with terminal device functionality.

[0125] In the embodiments of the present application, the functions of the network device may also be performed by a module (such as a chip) in the network device, or by a control subsystem that includes the network device function. The control subsystem that includes the network device function here may be a control center in the above-mentioned application scenarios such as smart grid, industrial control, intelligent transportation, and smart city. The functions of the terminal device may also be performed by a module (such as a chip or a modem) in the terminal device, or by a device that includes the terminal device function. In the following, the example in which the terminal device function is performed by the terminal and the network device function is performed by the base station is described.

[0126] With the development of 5G technology, 5G networks are placing increasingly higher demands on terminal capabilities. This increased demand for terminal capabilities necessitates a corresponding increase in terminal hardware, which inevitably increases terminal power consumption. Compared to LTE terminals, 5G terminals support a maximum power of 29dBm. Under typical services, such as comprehensive web browsing, instant messaging, gaming, or food consumption, 5G terminal communication power consumption increases by an average of over 200% compared to LTE terminals. Terminal battery life is a crucial aspect of user experience and impacts the suitability of 5G terminals or services. Therefore, ensuring the battery life of 5G terminals faces significant challenges, and research on how to reduce 5G terminal power consumption is key to addressing this issue.

[0127] At present, in order to save the power consumption of the terminal, the terminal can enter the sleep state, and the wake-up signal (WUS) can be used to wake up the terminal. If the terminal does not receive the WUS, or the WUS indicates not to wake up, the terminal will remain in the sleep state. If the terminal receives the WUS indication to wake up, the terminal can wake up from the sleep state and perform data transmission. Referring to Figure 2, when the terminal wakes up from the sleep state to the active state to work, the uplink and downlink beams may be misaligned due to reasons such as terminal movement. In addition, due to outdated channel information, re-measurement is required, and synchronization timeout requires re-time and frequency domain synchronization. At this time, the terminal needs to re-synchronize in the time and frequency domain, and perform operations such as channel measurement and measurement feedback to align the uplink and downlink beams and obtain channel information. However, this process is lengthy and time-consuming, and the terminal cannot perform data transmission during this process, resulting in low efficiency of terminal data transmission.

[0128] In view of this, an embodiment of the present application provides a data transmission method. In this method, a terminal can transmit data in a progressive manner in response to a wake-up signal. In this way, the terminal can also transmit data during channel measurement, measurement feedback, and time-frequency domain synchronization, thereby improving the terminal's data transmission efficiency.

[0129] 3 , which is an exemplary flowchart of a data transmission method provided in an embodiment of the present application, may include the following operations.

[0130] S301: The base station sends a wake-up signal.

[0131] Correspondingly, the terminal receives the wake-up signal.

[0132] For example, the base station broadcasts or multicasts a wake-up signal, and the terminal can receive the broadcast or multicast wake-up signal. For another example, the base station can unicast the wake-up signal to the terminal. In the embodiment of the present application, the wake-up signal can be WUS or low power WUS (LP WUS).

[0133] In a possible implementation, the wake-up signal may instruct the terminal to wake up from the dormant state and enter the active state to perform work, such as data transmission.

[0134] S302: The terminal determines to transmit data in the first mode in response to the wake-up signal.

[0135] Similarly, the base station determines to transmit data through the first mode.

[0136] In the embodiment of the present application, the wake-up signal can be used to trigger the terminal to transmit data in the first mode, or the wake-up signal can instruct the terminal to transmit data in the first mode. It is understood that the first mode can be called a fast data transmission mode, or can be other names, which are not specifically limited in this application.

[0137] In the embodiment of the present application, "transmitting data" can be understood as sending data and / or receiving data, that is, in S202, the terminal responds to the wake-up signal and determines to send data through the first mode and / or determines to receive data through the first mode.

[0138] In one possible implementation, the first mode can be understood as transmitting data in a progressive manner. That is, the terminal can transmit data in a progressive manner in response to the wake-up signal. In one example, progressive data transmission can be understood as a gradual increase in the amount of data transmitted by the terminal and / or the bandwidth occupied by the data, such as gradually increasing from a small amount to a large amount.

[0139] It should be noted that the embodiments of the present application do not impose specific limitations on the amount of increased data and the size of the bandwidth. For example, the amount of data may grow exponentially, linearly, or randomly.

[0140] In the implementation of this application, in Mode 1, the amount of data transmitted by the terminal can gradually increase as the data is correctly received. For example, during downlink transmission, the base station can send data to the terminal. If the base station receives an acknowledgment (ACK), the amount of data sent by the base station to the terminal can gradually increase. Similarly, during uplink transmission, if the base station correctly receives data from the terminal, the amount of data sent by the terminal to the base station can gradually increase.

[0141] Optionally, the base station can adjust the parameter configuration of the data, such as the modulation and coding scheme (MCS), bandwidth or number of layers, so that the amount of data gradually increases. The following is a detailed description of the configuration of the terminal by the base station in the embodiment of the present application.

[0142] In one possible implementation, when a terminal transmits data using the first mode, the bandwidth occupied by the data can be progressive, that is, it can increase gradually. For example, the bandwidth occupied by the data can increase after each successful data transmission. For example, in downlink data transmission, the bandwidth occupied by the data can increase gradually after each ACK is received by the base station. For example, in uplink data transmission, the bandwidth occupied by the data can increase gradually after each successful data reception by the base station. The following describes how a base station configures bandwidth for a terminal using Cases 1 and 2.

[0143] Case 1: The base station configures the location of the bandwidth for the nth transmission for the terminal.

[0144] In case 1, the base station may configure one or more first transmission bandwidths to the terminal. For example, the base station may send first configuration information to the terminal, and the first configuration information may indicate one or more first transmission bandwidths, such as one or more bandwidth parts (BWP). It is understandable that the sizes of the one or more first transmission bandwidths may be the same, or may be partially or completely different, and this application does not specifically limit this. The first transmission bandwidth may be the maximum transmission bandwidth available for data during data transmission by the terminal. Optionally, the first configuration information may be radio resource control (RRC) signaling, such as RRC reconfiguration.

[0145] In some embodiments, the base station may further configure a second transmission bandwidth usable for the nth transmission to the terminal, or this may be understood as the base station configuring the size of the second transmission bandwidth usable for the nth transmission to the terminal, where n is a positive integer. The second transmission bandwidth may be the maximum transmission bandwidth available for data transmitted by the terminal during the nth transmission. It is understood that the base station may configure the second transmission bandwidth to the terminal using configuration information different from the first configuration information, such as second configuration information. Optionally, the second configuration information may be RRC signaling. Alternatively, the base station may configure the second transmission bandwidth to the terminal using the first configuration information, meaning that the first configuration information may also indicate the second transmission bandwidth used for the nth transmission. Optionally, the nth transmission may occur after or before the nth correct transmission. In other words, the second transmission bandwidth may be the maximum available transmission bandwidth after or before the nth correct transmission of data.

[0146] In one example, the second transmission bandwidth may be part or all of the first transmission bandwidth, such as 1 / 4, 1 / 2, 3 / 4 or 1 of the first transmission bandwidth, etc., which is not specifically limited in this application. For example, as shown in FIG4A , the base station may indicate multiple second transmission bandwidths to the terminal, such as the base station may indicate to the terminal that the second transmission bandwidth that can be used for the first transmission (such as before or after the first correct transmission) is 1 / 4 of the first transmission bandwidth, the second transmission bandwidth that can be used for the second transmission (such as before or after the second correct transmission) is 1 / 2 of the first transmission bandwidth, and the second transmission bandwidth that can be used for the third transmission (before or after the third correct transmission) is 3 / 4 of the first transmission bandwidth, etc.

[0147] In the above example, if the first configuration information indicates multiple first transmission bandwidths, then one first transmission bandwidth may correspond to multiple second transmission bandwidths. In other words, the base station may indicate to the terminal the second transmission bandwidth that can be used for the nth transmission in each first transmission bandwidth.

[0148] In another example, the above-mentioned second transmission bandwidth may be part or all of the activation transmission bandwidth, such as 1 / 4, 1 / 2, 3 / 4 or 1 of the activation transmission bandwidth, etc., which is not specifically limited in this application. It is understandable that the base station may indicate to the terminal to activate one of the one or more first transmission bandwidths mentioned above, and then the activated first transmission bandwidth may be understood as the activation transmission bandwidth involved in the embodiment of the present application. Exemplarily, as shown in FIG4A , the base station may indicate multiple second transmission bandwidths to the terminal, such as the base station may indicate to the terminal that the second transmission bandwidth that can be used for the first transmission (such as before or after the first correct transmission) is 1 / 4 of the activation transmission bandwidth, the second transmission bandwidth that can be used for the second transmission (such as before or after the second correct transmission) is 1 / 2 of the activation transmission bandwidth, and the second transmission bandwidth that can be used for the third transmission (such as before or after the third correct transmission) is 3 / 4 of the activation transmission bandwidth, etc.

[0149] In one possible implementation, the base station may instruct the terminal to activate one of one or more first transmission bandwidths. In the embodiment of the present application, the manner in which the base station instructs the activation of the transmission bandwidth is not specifically limited. Then the terminal can determine the maximum transmission bandwidth available for transmitting data in the first mode, and can also determine the maximum transmission bandwidth that the data can occupy during the nth transmission, that is, the second transmission bandwidth. The base station may also send downlink control information (DCI) to the terminal. For example, before the nth data transmission, the base station may send DCI to the terminal. The DCI may indicate the position of the second transmission bandwidth in the activated transmission bandwidth, that is, the DCI may indicate the resource block (RB) used for data transmission.

[0150] Exemplarily, the activated transmission bandwidth can be divided into multiple resource block groups (RBGs), and a bit map can be used to indicate which RBG is activated. For example, referring to FIG4B , the activated transmission bandwidth is divided into 8 RBGs, and the base station uses "11000000" to indicate that the first two RBGs are activated for the first transmission (such as before or after the first correct transmission), accounting for 1 / 4 of the activated transmission bandwidth. The base station uses "11110000" to indicate that the first four RBGs are activated for the second transmission (such as before or after the second correct transmission), accounting for 1 / 2 of the activated transmission bandwidth, and so on.

[0151] It is understandable that the above-mentioned method of indicating the position of the second transmission bandwidth by a bit map is only shown as an example and does not constitute a limitation of the method of indicating the position of the second transmission bandwidth in the embodiment of the present application. Those skilled in the art can also indicate the position of the second transmission bandwidth in other ways, such as using the resource block (RB) starting position and RB length to indicate the position of the second transmission bandwidth. For example, in Figure 4B, the base station can indicate the same RB starting position and indicate different RB lengths for each transmission to indicate the position of the second transmission bandwidth.

[0152] Based on the above solution, the base station can indicate to the terminal the second transmission bandwidth that can be used for the nth transmission, thereby gradually increasing the transmission bandwidth and thus enabling progressive data transmission. By indicating the location of the second transmission bandwidth through the DCI, the terminal can determine the frequency domain locations at which data can be transmitted during the nth transmission.

[0153] Case 2: the base station configures different first transmission bandwidths for the terminal.

[0154] In scenario 2, the base station can configure multiple first transmission bandwidths for the terminal. For example, the base station can send first configuration information to the terminal, which can indicate multiple first transmission bandwidths, such as multiple BWPs. It is understood that each first transmission bandwidth can be of different sizes. The base station can activate first transmission bandwidths of different sizes through DCI instructions, such as instructing a switch from a small bandwidth to a large bandwidth, thereby gradually increasing the transmission bandwidth.

[0155] For example, referring to Figure 5, the base station configures multiple BWPs for the terminal. The base station instructs the terminal to activate the first BWP for the first transmission (e.g., before or after the first correct transmission) through DCI, and instructs the terminal to activate the second BWP for the second data transmission (e.g., before or after the second correct transmission) through DCI, and so on, thereby gradually increasing the transmission bandwidth.

[0156] Optionally, the base station may indicate the position of the RB used for data transmission in the activated transmission bandwidth through DCI. Please refer to the relevant description in Case 1 and will not repeat it here.

[0157] In the embodiments of the present application, the MCS used for data transmission can also be increased gradually. Since the beam is inaccurate and the channel information is incomplete when the terminal wakes up from the dormant state to the active state, the MCS used for data does not require high-order modulation. As the terminal obtains more information, such as channel information and beam information, the amount of data transmitted by the terminal can gradually increase, so the MCS can also be gradually increased.

[0158] In one example, the MCS can be gradually increased by gradually increasing the MCS indicator bits. For example, the MCS indicator bits used for data transmission can be indicated in a pre-agreed manner, such as a pre-configured or protocol-predetermined manner. For example, the MCS used for data transmission is pre-agreed for the nth transmission, such as before the nth correct transmission or after the nth correct transmission. Exemplarily, it can be pre-agreed that the MCS indicator bits start from a first number of bits, such as 1 bit, 2 bits, or 3 bits or more bits, corresponding to the maximum MCS of quadrature phase shift keying (QPSK). After each correct transmission, the MCS indicator bits increase by a second number of bits, such as 1 bit, 2 bits, or more bits, corresponding to the maximum MCS of 16 quadrature amplitude modulation (QAM), until the MCS indicator bits gradually increase to a third number of bits, such as 4 bits or 5 bits. In this way, by gradually increasing the number of MCS indicator bits, the MCS used for data can be gradually increased.

[0159] In another example, a correspondence between the MCS and the number of antenna ports or data streams for the demodulation reference signal (DMRS) can be defined. Since a low number of streams in data transmission typically indicates poor channel quality, a low-order modulation scheme can be selected, and thus the number of MCS indicator bits can be reduced. For example, Table 1 shows a correspondence between the number of antenna ports and the MCS.

[0160] Table 1: Example of the relationship between the number of antenna ports and MCS

[0161] As shown in Table 1, when the number of antenna ports for data transmission is one, or the number of data streams is one, the MCS selection range is MCS0 to MCS4, corresponding to QPSK. When the number of antenna ports for data transmission is two, or the number of data streams is two, the MCS selection range is MCS5 to MCS10, and so on.

[0162] Based on the above solution, the correspondence between the number of antenna ports or the number of data streams during data transmission and the MCS can be predefined, so that the terminal and the base station can select the corresponding MCS to modulate the data according to the correspondence during data transmission.

[0163] In another example, the wake-up signal may indicate one or more timing windows. For example, the wake-up signal may indicate the start time and length of the timing window. In another example, the wake-up signal may indicate the start time and end time of the timing window. In this example, the correspondence between the timing window and the MCS may be pre-agreed.

[0164] For example, referring to Figure 6, timing window A is associated with MCS1. When a terminal transmits data within timing window A, it can use MCS1. Timing window B is associated with MCS2. When a terminal transmits data within timing window B, it can use MCS2. In this example, as time passes, the terminal acquires more information, such as channel information and beam information, and the MCS may also increase over time.

[0165] For example, timing window A may be associated with MCS table 1, and the base station may indicate in MCS table 1 the MCS used for data transmission within timing window A. Timing window B may be associated with MCS table 2, and the base station may indicate in MCS table 2 the MCS used for data transmission within timing window B.

[0166] It should be noted that the MCS table associated with the timing window can be a part of the MCS table associated in the related art. In this way, through the association between the timing window and the MCS table, the MCS can also be increased over time.

[0167] Optionally, the one or more timing windows indicated by the wake-up signal may also be associated with the transmission bandwidth used by the data. That is, the base station may configure the activation transmission bandwidth used by the data to the terminal via the wake-up signal. It is understood that the activation transmission bandwidths associated with different timing windows may be different or the same, and this application does not impose any specific limitations thereon.

[0168] In an embodiment of the present application, data is transmitted progressively, and control information, such as DCI, may also be transmitted progressively. In one possible scenario, the change pattern of the number of control resource sets (CORESETs) carrying control information may be the same as the change pattern of the maximum available bandwidth (first transmission bandwidth) in the first mode of data transmission, that is, the number of control resource sets may increase as the aforementioned first transmission bandwidth increases. In this case, the base station may configure m first transmission bandwidths of different sizes for the terminal through configuration information, such as RRC signaling, as shown in the aforementioned scenario 2. The base station may configure m groups of control resource sets for the terminal through configuration information, each group of control resource sets may include one or more control resource sets, and the m groups of control resource sets correspond one-to-one to the m first transmission bandwidths. For example, referring to FIG7A , the number of control resource sets corresponding to BWP1 may be indicated as X through configuration information, and gradually increases as BWP increases, to a maximum of Y. Wherein, X and Y are both positive integers, and X and Y may be the same or different.

[0169] In another possible scenario, the change pattern of the size of the control resource set may be the same as the change pattern of the maximum available bandwidth (second transmission bandwidth) in the nth transmission, that is, the size of the control resource set may increase as the second transmission bandwidth increases. In this case, the base station may configure the size and number of the control resource sets that carry the control information for scheduling the nth transmission for the terminal through configuration information, such as RRC signaling. For example, referring to FIG7B , the size and number of the control resource sets that carry the control information for scheduling the first transmission, the size and number of the control resource sets that carry the control information for scheduling the second transmission, and the size and number of the control resource sets that carry the control information for scheduling the third transmission may be indicated to the terminal through configuration information. As shown in FIG7B , as the data is correctly transmitted, the size of the control resource set gradually increases. Optionally, the number of control resource sets gradually decreases.

[0170] Based on the above two possible situations, the base station can configure a progressive control resource set for the terminal. The terminal can blindly detect the physical downlink control channel (PDCCH) in the configured control resource set to obtain DCI. Therefore, the progressive control resource set can realize progressive transmission of control information.

[0171] Optionally, the configuration information in the embodiment of the present application may also indicate the aggregation level of the non-carrier coverage extension (CCE) used for PDCCH blind detection. For example, the aggregation level of the search space is adapted to the blind detection of a small amount of data, and the CCE range is indicated as A through DCI. As the data is correctly transmitted, the CCE range can be changed to B, C, etc. For example, the base station can indicate to the terminal through DCI that the CCE range is {1,2}. As the data is correctly transmitted, such as as the number of ACKs received by the base station increases, the base station can indicate to the terminal through DCI that the CCE range is {1,2,4,8,16}. For another example, the relationship between the channel quality indicator (CQI) and the CCE can be defined, as shown in Table 2, and the base station can indicate to the terminal through DCI to select the corresponding CCE according to the CQI.

[0172] Table 2: Example of a relationship between CQI and CCE

[0173] As shown in Table 2, the base station can instruct the terminal through DCI to select the corresponding CCE according to the CQI, so the terminal can determine the CQI. For example, if the CQI is 22, the terminal can select CCE 2 to perform blind detection of the PDCCH.

[0174] In one possible implementation, the antenna port may be indicated by DCI. In an embodiment of the present application, the number of data streams in the first mode of data transmission may only support a fixed number of streams, such as 1 stream, 2 streams, etc., which can be implemented through the antenna port table. Optionally, the DCI may not include code division multiplexing (CDM) information, such as a CDM group. That is, the DCI indicates the frequency domain configuration no CDM group. For example, in the antenna port table shown in Table 3, the second column may not exist. Optionally, the DCI indicates that the number of time domain symbols of DMRS is a specified number, such as 1. That is, in the antenna port table, the number of time domain symbols of DMRS is a specified number, such as 1.

[0175] Table 3:

[0176] It is understood that the antenna port table shown in Table 3 is part of the antenna port table in the related art and is shown only as an example. In the embodiment of the present application, the antenna port table in the first mode can be part of the antenna port table in the related art as shown in Table 3, or it can be a newly defined table, and this application does not make any specific limitations.

[0177] Optionally, in the first mode, the number of transport blocks (TBs) is fixed, such as 1 or 2, to reduce DCI overhead. A maximum TB size can be determined based on the aforementioned MCS and RBs to indicate data transmission.

[0178] Based on this solution, the number of indication bits of the DCI can be reduced, thereby reducing the overhead of the DCI. Therefore, in the first mode, the length of the DCI may be inconsistent. Therefore, the base station can fill the DCI of different lengths with padding bits to make the length of the DCI consistent. Referring to Figure 8, since the base station can determine how many bits are reduced in the process of generating the DCI, the base station can directly fill the padding bits in the DCI. Optionally, the padding bits can be a radio frequency channel map (RF-map), such as including the angle of the multipath, the relative position of the base station and the terminal, the perception result, the speed of the target user, the position of the target user, one or more of bit 0 or bit 1.

[0179] In an embodiment of the present application, the response message of the data may also be progressively transmitted. In one possible scenario, a response message, such as ACK and / or non-acknowledgement (NACK), may include one or more of a signal-to-noise ratio (SNR), a signal-to-interference-plus-noise ratio (SINR), a reference signal receiving power (RSRP), or a reference signal receiving quality (RSRQ). It will be understood that the above-mentioned SINR, SNR, RSRP, and RSRQ may be measurement results of signals carrying data. That is, during downlink transmission, the terminal may feed back the measurement results of the signal to the base station. Optionally, the response message may further include one or more of an indication of whether the decoding is correct or a reference MCS. The reference MCS may correspond to the aforementioned measurement results.

[0180] For example, during downlink data transmission, if the terminal correctly decodes the received data, the terminal may send an ACK to the base station. The ACK may indicate to the terminal that the data was correctly decoded. The ACK may also include a measurement result of the signal carrying the data and a reference MCS corresponding to the measurement result. If the terminal does not correctly decode the received data, the terminal may send a NACK to the base station. The NACK may indicate to the terminal that the data was not correctly decoded. The NACK may also include a measurement result of the signal carrying the data and a reference MCS corresponding to the measurement result.

[0181] In some embodiments, a correspondence between a measurement result and an MCS may be predefined, for example, a correspondence between an SNR and an MCS may be predefined, as shown in Table 4.

[0182] Table 4: An example of the relationship between SNR and MCS

[0183] As shown in Table 4, when the measured SNR is 1, the reference MCS can be 1; when the SNR is 2, the reference MCS can be 2; when the SNR is 3, the reference MCS can be 2; and when the SNR is 24, the reference MCS can be 27. In other words, one SNR value can correspond to one MCS value. The terminal can carry the reference MCS information in the ACK / NACK. The SNR values ​​described in Table 4 are related to the number of antennas and the amount of path loss. The higher the number of antennas, the greater the SNR gain. The greater the path loss, the lower the SNR gain. After each SNR measurement, the terminal can determine the reference MCS based on Table 4 and feedback it to the base station through ACK / NACK.

[0184] It is understood that the correspondence between SNR and MCS shown in Table 4 is only shown as an example and does not constitute a limitation on the correspondence between SNR and MCS. The correspondence between SNR and MCS can also be the correspondence between SNR value ranges and MCS values, such as SNR values ​​0 to 6 corresponding to MCS value 0, SNR values ​​7 to 12 corresponding to MCS value 1, etc., which is not specifically limited in this application. Similarly, the correspondence between SINR, RSRP or RSRQ equal to MCS can be implemented with reference to Table 4.

[0185] Optionally, the terminal may not carry the reference MCS information in the ACK / NACK, but may carry the measurement result of the data-carrying signal, such as SNR. In this way, the base station may also determine the reference MCS according to the corresponding relationship shown in Table 4.

[0186] During uplink transmission, the base station can measure the data-carrying signal to obtain a measurement result, such as SNR. The base station can determine the reference MCS based on the corresponding relationship shown in Table 4.

[0187] In some embodiments, the base station may determine the MCS to be used for the next data transmission based on the reference MCS in the ACK / NACK. For example, the base station may use the reference MCS as the MCS to be used for the next data transmission and indicate it to the terminal through the DCI. For another example, referring to FIG9 , the base station may determine the MCS to be used for the next data transmission based on the reference MCS and the measured MCS. The measured MCS may be an MCS selected based on channel quality indicator (CQI) measurement feedback, or may be an MCS based on environmental information feedback from the RF-MAP, or may be the MCS used for the previous transmission.

[0188] Based on the above solution, the base station can determine the MCS to be used for the next transmission by measuring the data-carrying signal, which is more timely and accurate than the MCS adjustment solution in the related art.

[0189] Optionally, in downlink data transmission, the downlink data demodulation result needs to be quickly fed back as an ACK. Therefore, the base station can configure the K2 range to a specified time slot range in time domain resource allocation through RRC signaling to shorten the feedback interval. For example, the K2 range can be configured to be 0 to 5 time slots. K2 represents the time domain interval from the start of DCI reception to the transmission of the uplink PUSCH ACK / NACK.

[0190] S303: The terminal determines to transmit data through the second mode.

[0191] This step is optional and is shown by a dotted line in Figure 3. Similarly, the base station determines to transmit data in the second mode.

[0192] For example, the terminal can switch from the first mode to the second mode and transmit data via the second mode. Referring to Figure 10, after receiving the wake-up signal, the terminal can transmit data via the first mode. In the first mode, the terminal can transmit data in a progressive manner. Optionally, as shown in Figure 10, during this period, the terminal can measure the channel quality and feed it back to the base station via channel state information (CSI).

[0193] In one possible scenario, the switching from the first mode to the second mode may be determined by the terminal based on a switching condition. It is understood that the switching condition may be indicated by the base station. For example, the base station may carry the switching condition in a DCI, RRC signaling, or paging message. Alternatively, the switching condition may be predefined by a protocol and is not specifically limited in this application.

[0194] Optionally, the switching condition may be that a measurement result of a signal carrying data is greater than or equal to a first threshold, such as RSRP is greater than or equal to the first threshold, or channel quality is greater than or equal to a second threshold.

[0195] In another possible scenario, the wake-up signal in S301 may indicate the duration of a timer, and upon expiration of the timer, the terminal may transmit data in the second mode. For example, upon receiving the wake-up signal, the terminal may start a timer and transmit data in the first mode. Upon expiration of the timer, the terminal may switch to the second mode and transmit data in the second mode.

[0196] In another possible scenario, the wake-up signal in S301 may indicate the value of a counter. When the counter reaches this value, the terminal may transmit data using the second mode. It should be noted that the value of the counter may be related to the number of ACK feedbacks or the number of CSI feedbacks. For example, after receiving the wake-up signal, the terminal may transmit data using the first mode. Each transmission may be counted as one time, each correct transmission may be counted as one time, or each time CSI is sent as one time. The counter counts, and when the counter reaches this value, the terminal may switch to the second mode and transmit data using the second mode.

[0197] In another possible scenario, the switch from the first mode to the second mode may be instructed by the base station. For example, the base station may instruct the terminal to switch from the first mode to the second mode via DCI or RRC signaling. Optionally, during downlink data transmission, the terminal may send demodulation results or measurement results to the base station, and the base station may determine whether to perform mode switching. Optionally, during uplink data transmission, the base station may determine whether to perform mode switching based on the demodulation results or measurement results.
