Description

Technical Field

[0001] This application relates to the field of wireless communication technologies, and in particular, to a data transmission method and apparatus. Background Art

[0002] Currently, in order to save the power consumption of a terminal, the terminal can enter a sleep state, and a 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 indicating 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 for work, due to reasons such as terminal movement, the uplink and downlink beams may be misaligned. In addition, since the channel information is outdated and needs to be re-measured, and the synchronization times out and needs to re-perform time-frequency domain synchronization, etc. At this time, the terminal needs to re-perform time-frequency domain synchronization, 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 long 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

[0003] This application provides a data transmission method and apparatus, which are used to reduce the time required between the wake-up of a terminal device and data transmission.

[0004] In a first aspect, a data transmission method is provided. This method can be applied to the terminal side, such as a terminal or a communication module in the terminal, or a circuit or chip in the terminal responsible for communication functions (such as a modulation and demodulation (Modem) chip, also known as a baseband chip, or a system-on-chip (SoC) chip or a system-in-package (SIP) chip containing a modem core). Taking this method applied to a terminal as an example. In this method, the terminal device receives a wake-up signal, and the wake-up signal indicates waking up from the sleep state. The terminal device determines to transmit data through a first mode in response to the wake-up signal. Wherein, the first mode indicates transmitting data in a progressive manner.

[0005] 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 perform data transmission during processes such as channel measurement, measurement feedback, and time-frequency domain synchronization, thereby improving the data transmission efficiency of the terminal.

[0006] Optionally, transmitting data in a progressive manner may include that the amount of data transmitted and / or the bandwidth occupied by the data increase from small to large.

[0007] In a possible implementation, the progressive manner includes that the amount of data transmitted grows exponentially or linearly. Based on the above solution, after the terminal device wakes up, the uplink and downlink beams may be misaligned due to reasons such as movement. Therefore, the terminal device can transmit a small amount of data. After processes such as 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.

[0008] In a possible implementation, the terminal device receives first configuration information, and the first configuration information indicates a first transmission bandwidth, where the first transmission bandwidth is the maximum transmission bandwidth used for transmitting data in the first mode. Based on the above solution, the network device can indicate to the terminal device the transmission bandwidth used for transmitting data in the first mode through the first configuration information. Optionally, the transmission bandwidth used for transmitting data in the first mode can be progressive, so progressive data transmission can be achieved.

[0009] In a possible implementation, the first configuration information further indicates a second transmission bandwidth available 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.

[0010] Based on the above solution, the network device can indicate to the terminal device the transmission bandwidth used for the nth data transmission through the first configuration information, and the transmission bandwidth can be made progressive, so the amount of data can also be progressive.

[0011] In a possible implementation, the terminal device receives downlink control information, and the downlink control information indicates the position of the second transmission bandwidth in the active transmission bandwidth, where the active transmission bandwidth is the first transmission bandwidth.

[0012] Based on the above solution, the network device can indicate to the terminal device the frequency domain resources used for data through the downlink control information.

[0013] In a possible implementation, the modulation and coding strategy used for data is associated with the number of streams of the data (modulation and coding scheme, MCS).

[0014] Based on the above solution, 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 for data with the number of data streams, when the number of data streams gradually increases, the MCS can also gradually increase.

[0015] In a possible implementation, the wake-up signal indicates the position of the timing window. Among them, the timing window is associated with at least one modulation and coding strategy. The terminal device determines to transmit data within the timing window in the first mode, using at least one modulation and coding strategy associated with the timing window.

[0016] Based on the above solution, after activation, the terminal device can perform channel measurement, measurement feedback, time-frequency domain synchronization, etc. Therefore, over time, the terminal device can gradually obtain complete channel information. Therefore, by associating the timing window with the MCS, the gradual increase of the MCS can be achieved.

[0017] In a possible implementation, the terminal device receives downlink control information, and the downlink control information indicates the antenna port, and the antenna port is used to determine the number of streams when transmitting data in the first mode. Among them, the downlink control information does not contain code division multiplexing information. Or, the downlink control information indicates that the demodulation reference signal is a specified number.

[0018] Based on the above solution, the downlink control information does not contain code division multiplexing information. Or, the downlink control information indicates that the demodulation reference signal is a specified number, which can reduce the number of bits of the downlink control information, so the overhead of the downlink control information can be reduced.

[0019] In a possible implementation, the terminal device receives second configuration information, and the second configuration information indicates the size of the control resource set, and the change rule of the size of the control resource set is the same as that of the second transmission bandwidth.

[0020] Based on the above solution, the data is transmitted progressively, and the downlink control information can also be transmitted progressively. Therefore, by configuring the change rule of the size of the control resource set to be the same as that of the second transmission bandwidth, the progressive transmission of the downlink control information can be achieved.

[0021] In a possible implementation, the terminal device receives third configuration information, and the third configuration information indicates m groups of control resource sets, and the number of the first transmission bandwidths is m. Among them, the m groups of control resource sets correspond to the m first transmission bandwidths one by one, and one group of control resource sets includes one or more control resource sets. Among them, m is a positive integer.

[0022] Based on the above solution, the network device indicates m groups of control resource sets corresponding to the m first transmission bandwidths to the terminal device through the third configuration information. When activating one of the m first transmission bandwidths, the terminal device can blindly detect the downlink control information on the control resource set corresponding to the activated first transmission bandwidth.

[0023] In a possible implementation, the terminal device sends an acknowledgment message for data, and the acknowledgment message includes measurement results obtained by measuring the signal carrying the data. Based on the above solution, the terminal device can feedback the measurement results to the network device and indicate the channel environment to the network device.

[0024] In a possible implementation, the acknowledgment message further includes at least one of the following: indication information on whether decoding is correct or a reference modulation and coding strategy. The reference modulation and coding strategy corresponds to the measurement results.

[0025] Based on the above solution, the terminal device can indicate the reference MCS to the network device, enabling the base station to determine the MCS to be used for the next transmission, which is more timely and accurate compared to the MCS adjustment solutions in the related art.

[0026] In a possible implementation, the downlink control information further includes padding bits, and the padding bits include one or more of radio frequency channel mapping data RF map, sensing results, the speed of the target, the location of the target, bit 0, or bit 1.

[0027] Based on the above solution, the network device can pad the downlink control information of different lengths through the padding bits, so that the lengths of the downlink control information are consistent.

[0028] In a possible implementation, the terminal device receives fourth configuration information, and the fourth configuration information indicates the aggregation level used for blind detection of the physical downlink control channel. Alternatively, the fourth configuration information indicates that the aggregation level used for blind detection of the physical downlink control channel corresponds to the channel quality.

[0029] Based on the above solution, the network device can indicate the aggregation level used for blind detection of the physical downlink control channel to the terminal device through the fourth configuration information.

[0030] In a possible implementation, the terminal device transmits data in a second mode, which is different from the first mode. The condition for switching from the first mode to the second mode is indicated by the network device or predefined. Based on the above solution, the terminal device can switch to the second mode for data transmission, improving the data transmission performance.

[0031] In a possible implementation, the condition is carried in one of the downlink control information, radio resource control signal, or paging message.

[0032] In a possible implementation, the condition includes one or more of the following: the measurement result of the signal carrying the data is greater than or equal to a first threshold, or the 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.

[0033] In a possible implementation, the wake-up signal indicates a first duration. After the terminal device transmits data in the first mode for the first duration, it transmits data in the second mode, where the second mode is different from the first mode. Based on the above solution, the terminal device can switch to the second mode to transmit data when it reaches the first duration indicated by the wake-up signal.

[0115] The technical solution of the embodiment of the present application can be applied to a New Radio (NR) system, a Long Term Evolution (LTE) system, an LTE Frequency Division Duplex (FDD) system, an LTE Time Division Duplex (TDD), a Worldwide Interoperability for Microwave Access (WiMAX) communication system, a fifth-generation communication system (5 th generation, 5G), a next-generation wireless communication system, such as 6G, etc., which is not limited herein.

[0116] Figure 1 is a schematic diagram of the architecture of a communication system 1000 to which the embodiment of the present application is applied. As Figure 1 shown, the communication system includes a radio access network 100. Among them, the radio access network 100 may include at least one network device (such as Figure 1 110a and / or 110b in Figure 1 ), and may also include at least one terminal device (such as Figure 1 at least one of 120a - 120j in Figure 1 ). 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. The terminal devices and the network devices can be connected to each other by wire or wirelessly.

[0117] A network device is a network-side device with wireless transceiver capabilities. The network device can be a device in a radio access network (RAN) that provides wireless communication capabilities for terminal devices, called a RAN device. For example, the network device can be a base station, an evolved NodeB (eNodeB), a transmission reception point (TRP), a next generation NodeB (gNB) in a 5th generation (5G) mobile communication system, a next generation NodeB in a 6th generation (6G) mobile communication system, a base station in a future mobile communication system, or an access node in a WiFi system, etc.; it can also be a module or unit that completes some functions of the base station. For example, it can be a central unit (CU) or a distributed unit (DU). Here, the CU 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 some or all of the functions of the physical layer. For specific descriptions of the above various protocol layers, reference can be made to the relevant technical specifications of the 3rd generation partnership project (3GPP). The network device can be a macro base station (such as Figure 1 110a in Figure 1 ), or a micro base station or an indoor station (such as 110b in Figure 1 ), or a relay node or a donor node, etc. The embodiments of the present application do not limit the specific technologies and specific device forms adopted by the network device.

[0118] In another possible scenario, multiple RAN nodes cooperate to assist a terminal in achieving wireless access, and different RAN nodes respectively implement some functions of a base station. For example, the RAN node can be a CU, a DU, a CU-control plane (CP), a CU-user plane (UP), or a radio unit (RU), etc. The CU and the DU can be set separately, or can also be included in the same network element, such as a baseband unit (BBU). The RU can be included in a radio frequency device or a radio frequency unit, such as included in a remote radio unit (RRU), an active antenna unit (AAU), or a remote radio head (RRH).

[0119] In different systems, the CU (or CU-CP and CU-UP), the DU, or the 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, the CU can also be called an O-CU (open CU), the DU can also be called an O-DU, the CU-CP can also be called an O-CU-CP, the CU-UP can also be called an O-CU-UP, and the RU can also be called an O-RU. For the convenience of description, in this application, the CU, CU-CP, CU-UP, DU, and RU are used as examples for description. Any one of the 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.

[0120] The terminal device is a user-side device with wireless transceiver functions. The terminal device can also be referred to as a user equipment (UE), mobile station, mobile terminal, etc. The terminal device can be widely applied to 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, remote medical treatment, smart grid, smart furniture, smart office, smart wearables, smart transportation, smart city, etc. The terminal device can be a mobile phone, tablet computer, computer with wireless transceiver functions, wearable device, vehicle, drone, helicopter, airplane, ship, robot, robotic arm, smart home device, etc. The embodiments of the present application do not limit the specific technologies and specific device forms adopted by the terminal device.

[0121] The network device and the terminal device can be fixed in position or movable. The network device and the terminal device can be deployed on land, including indoor or outdoor, handheld or vehicle-mounted; they can also be deployed on the water surface; they can also be deployed on airplanes, balloons, and artificial satellites in the air. The embodiments of the present application do not limit the application scenarios of the network device and the terminal device.

[0122] The roles of the network device and the terminal device can be relative. For example, Figure 1 the helicopter or drone 120i in can be configured as a mobile network device. For the terminal devices 120j that access the radio access network 100 through 120i, the terminal device 120i is a network device; but for the network device 110a, 120i is a terminal device, that is, the communication between 110a and 120i is through the radio air interface protocol. Of course, the communication between 110a and 120i can also be through the interface protocol between network devices. At this time, relative to 110a, 120i is also a network device. Therefore, both the network device and the terminal device can be uniformly referred to as communication devices. Figure 1 110a and 110b in can be referred to as communication devices with network device functions. Figure 1 120a - 120j in can be referred to as communication devices with terminal device functions.

[0123] In an embodiment 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 may be performed by a control subsystem including the functions of the network device. The control subsystem including the functions of the network device here may be a control center in the above 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 may be performed by a device including the functions of the terminal device. In the following, an example will be described in which the functions of the terminal device are performed by the terminal and the functions of the network device are performed by the base station.

[0124] With the development of 5G technology, the 5G network has higher and higher requirements for the capabilities of terminals. As the requirements for terminal capabilities increase, the hardware of the terminal will increase accordingly, and the power consumption of the terminal will inevitably increase. Compared with LTE terminals, the maximum power supported by 5G terminals is 29 dBm. Under typical services, such as comprehensive web browsing, instant messaging, games, or food, etc., the communication power consumption of 5G terminals increases by more than 200% on average compared with LTE terminals. The long-term battery life of the terminal is an important aspect of the user experience and will affect the applicability of 5G terminals or services. Therefore, the long-term battery life of 5G terminals faces great challenges, and researching how to save the power consumption of 5G terminals is the key to solving this problem.

[0125] Currently, in order to save the power consumption of the terminal, the terminal can enter the sleep state, and a 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 indicating to wake up, the terminal can wake up from the sleep state and perform data transmission. Refer to Figure 2 When the terminal wakes up from the sleep state to the active state for work, due to reasons such as terminal movement, the uplink and downlink beams may not be aligned. In addition, due to the outdated channel information, re-measurement is required, and due to synchronization timeout, re-time-frequency domain synchronization is required, etc. At this time, the terminal needs to re-perform time-frequency domain synchronization, 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 long and time-consuming, and the terminal cannot perform data transmission during this process, resulting in low efficiency of terminal data transmission.

[0126] In view of this, an embodiment of the present application provides a data transmission method. In this method, the terminal can transmit data in a progressive manner in response to the wake up signal. In this way, the terminal can also perform data transmission during the processes of channel measurement, measurement feedback, and time-frequency domain synchronization, thereby improving the efficiency of terminal data transmission.

[0127] Refer to Figure 3 For an exemplary flowchart of a data transmission method provided by an embodiment of the present application, the following operations may be included.

[0128] S301: The base station sends a wake-up signal.

[0129] Correspondingly, the terminal receives the wake-up signal.

[0130] For example, the base station broadcasts or multicasts the 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 embodiments of the present application, the wake-up signal can be a WUS or a low-power WUS (LP WUS).

[0131] In a possible implementation manner, the wake-up signal can instruct the terminal to wake up from the sleep state and enter the active state for operation, such as for data transmission.

[0132] S302: In response to the wake-up signal, the terminal determines to transmit data through the first mode.

[0133] Similarly, the base station determines to transmit data through the first mode.

[0134] In the embodiments of the present application, the wake-up signal can be used to trigger the terminal to transmit data through the first mode, or it can be said that the wake-up signal can instruct the terminal to transmit data through the first mode. It can be understood that the first mode can be called a fast data transmission mode, or it can also be other names, which are not specifically limited in the present application.

[0135] In the embodiments of the present application, "transmitting data" can be understood as sending data and / or receiving data, that is, in S202, the terminal, in response to the wake-up signal, determines to send data through the first mode and / or determines to receive data through the first mode.

[0136] In a possible implementation manner, the first mode can be understood as transmitting data in a progressive manner. That is to say, the terminal can transmit data in a progressive manner in response to the wake-up signal. In an example, transmitting data in a progressive manner can be understood as the amount of data transmitted by the terminal and / or the bandwidth occupied by the data increasing gradually, such as increasing from small to large.

[0137] It should be noted that in the embodiments of the present application, the sizes of the increased data volume and bandwidth are not specifically limited. For example, the data volume can increase exponentially, linearly, or the increased data volume can be random.

[0138] 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, in the downlink transmission process, the base station can send data to the terminal. If the base station receives an acknowledgement (ACK), then the amount of data sent by the base station to the terminal can gradually increase. Similarly, in the uplink transmission process, if the base station correctly receives data from the terminal, then the amount of data sent by the terminal to the base station can gradually increase.

[0139] 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, etc., so that the amount of data gradually increases. Hereinafter, the configuration of the base station for the terminal in the embodiments of this application will be described in detail.

[0140] In a possible implementation manner, when the terminal transmits data through the first mode, the bandwidth occupied by the data can be progressive, that is, it can gradually increase. For example, the bandwidth occupied by the data can increase after each correct data transmission. Exemplarily, in downlink data transmission, the bandwidth occupied by the data can gradually increase after the base station receives an ACK each time. Exemplarily, in uplink data transmission, the bandwidth occupied by the data can gradually increase after the base station correctly receives data each time. Hereinafter, through Case 1 and Case 2, the manner in which the base station configures the bandwidth for the terminal will be introduced.

[0141] Case 1: The position where the base station configures the bandwidth for the nth transmission of the terminal.

[0142] In Case 1, the base station can configure one or more first transmission bandwidths for the terminal. For example, the base station can send first configuration information to the terminal, and the first configuration information can indicate one or more first transmission bandwidths, such as one or more bandwidth parts (BWPs). It can be understood that the sizes of these one or more first transmission bandwidths can be the same, or partially or completely different, and this application does not make specific limitations. Among them, the first transmission bandwidth can be the maximum transmission bandwidth available for the data when the terminal is transmitting data. Optionally, the first configuration information can be radio resource control (RRC) signaling, such as RRC reconfiguration, etc.

[0143] In some embodiments, the base station may also configure a second transmission bandwidth available for the nth transmission for the terminal, or it can be understood that the base station may configure the size of the second transmission bandwidth available for the nth transmission for the terminal, where n is a positive integer. The second transmission bandwidth may be the maximum transmission bandwidth available for the terminal when transmitting data in the nth transmission. It can be understood that the base station may configure the second transmission bandwidth for the terminal through configuration information different from the first configuration information, such as the second configuration information. Optionally, the second configuration information may be an RRC signaling. Alternatively, the base station may configure the second transmission bandwidth for the terminal through the first configuration information, that is, the first configuration information may also indicate the second transmission bandwidth used in the nth transmission. Optionally, the above nth transmission may be after the nth correct transmission or before the nth correct transmission. That is, the second transmission bandwidth may be the maximum transmission bandwidth available after the nth data is correctly transmitted or before the nth data is correctly transmitted.

[0144] In one example, the above 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., and the present application does not make specific limitations. Exemplarily, as Figure 4A shown, the base station may indicate multiple second transmission bandwidths to the terminal. For example, the base station may indicate that the second transmission bandwidth available 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 available 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 available for the third transmission (before or after the third correct transmission) is 3 / 4 of the first transmission bandwidth, etc.

[0145] 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. That is, the base station may indicate to the terminal the second transmission bandwidth available for the nth transmission in each first transmission bandwidth.

[0146] In another example, the above second transmission bandwidth may be part or all of the active transmission bandwidth, such as 1 / 4, 1 / 2, 3 / 4, or 1 of the active transmission bandwidth, etc., and the present application does not make specific limitations. It can be understood that the base station may indicate to the terminal to activate one of the above one or more first transmission bandwidths, and then the activated first transmission bandwidth may be understood as the active transmission bandwidth involved in the embodiments of the present application. Exemplarily, as Figure 4AAs shown, the base station may indicate multiple second transmission bandwidths to the terminal. For example, the base station may indicate that the second transmission bandwidth available for the first transmission (before or after the first correct transmission) is 1 / 4 of the active transmission bandwidth, the second transmission bandwidth available for the second transmission (before or after the second correct transmission) is 1 / 2 of the active transmission bandwidth, the second transmission bandwidth available for the third transmission (before or after the third correct transmission) is 3 / 4 of the active transmission bandwidth, and so on.

[0147] In a possible implementation, the base station may indicate to the terminal to activate one of one or more first transmission bandwidths. In the embodiments of this application, the manner in which the base station indicates the activation of the transmission bandwidth is not specifically limited. Then the terminal can determine the maximum transmission bandwidth available when 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 active transmission bandwidth, that is, the DCI may indicate the resource block (RB) used for data transmission.

[0148] Exemplarily, the active transmission bandwidth may be divided into multiple resource block groups (RBGs), and a bitmap may be used to indicate which RBG is activated. For example, referring to Figure 4B , the active transmission bandwidth is divided into 8 RBGs. The base station indicates that the first two RBGs are activated for the first transmission (before or after the first correct transmission) through "11000000", accounting for 1 / 4 of the active transmission bandwidth. The base station indicates that the first 4 RBGs are activated for the second transmission (before or after the second correct transmission) through "11110000", accounting for 1 / 2 of the active transmission bandwidth, and so on.

[0149] It can be understood that the above manner of indicating the position of the second transmission bandwidth through a bitmap is only shown as an example and does not constitute a limitation on the manner of indicating the position of the second transmission bandwidth in the embodiments of this application. Those skilled in the art can also indicate the position of the second transmission bandwidth in other ways, such as using the start position and length of the resource block (RB) to indicate the position of the second transmission bandwidth. For example, in Figure 4B , during each transmission, the base station may indicate the same RB start position and respectively indicate different RB lengths to indicate the position of the second transmission bandwidth.

[0150] Based on the above solution, the base station can indicate to the terminal the second transmission bandwidth available for the nth transmission, so that the transmission bandwidth can be gradually increased, and thus data can be transmitted in a progressive manner. By indicating the position of the second transmission bandwidth through DCI, the terminal can determine at which frequency domain positions it can transmit data during the nth transmission.

[0151] Case 2: The base station configures different first transmission bandwidths for the terminal.

[0152] In Case 2, the base station can configure multiple first transmission bandwidths for the terminal. For example, the base station can send the first configuration information to the terminal, and the first configuration information can indicate multiple first transmission bandwidths, such as multiple BWPs. It can be understood that the sizes of each first transmission bandwidth are different. The base station can indicate the activation of different-sized first transmission bandwidths through DCI, such as indicating a switch from a small bandwidth to a large bandwidth to achieve a gradual increase in the transmission bandwidth.

[0153] Exemplarily, referring to Figure 5 , the base station configures multiple BWPs for the terminal. The base station indicates through DCI that the terminal activates the first BWP for the 1st transmission (such as before or after the 1st correct transmission), and the base station indicates through DCI that the terminal activates the second BWP for the 2nd data transmission (such as before or after the 2nd correct transmission), and so on, to achieve a gradual increase in the transmission bandwidth.

[0154] Optionally, the base station can indicate through DCI the RBs used for data transmission at the position of the activated transmission bandwidth. For relevant descriptions, reference can be made to those in Case 1, which will not be elaborated here.

[0155] In the embodiments of the present application, the MCS used for data transmission can also increase progressively. Since the terminal wakes up from the dormant state to the active state for operation, the beam is inaccurate and the channel information is incomplete. Therefore, high-order modulation is not required for the MCS used for data. As the terminal obtains more information, such as channel information and beam information, etc., the amount of data transmitted by the terminal can gradually increase, and thus the MCS can also gradually increase.

[0156] In one example, the step - by - step increase of the MCS can be achieved by gradually increasing the indication bit of the MCS. For example, the indication bit of the MCS used for data transmission can be indicated in a pre - agreed manner, such as pre - configuration or protocol - predefined manner. For instance, it can be pre - agreed that for the nth transmission, such as before the nth correct transmission or after the nth correct transmission, the MCS used for data transmission. Exemplarily, it can be pre - agreed that the indication bit of the MCS starts from the first number of bits, such as 1 bit, 2 bits, 3 bits or more bits, corresponding to the maximum MCS being quadrature phase shift keying (QPSK). After each correct transmission, the indication bit of the MCS increases by the second number of bits, such as 1 bit, 2 bits or more bits, etc., corresponding to the maximum MCS being 16 - quadrature amplitude modulation (QAM), until the indication bit of the MCS gradually increases to the third number of bits, such as 4 bits or 5 bits. In this way, by gradually increasing the number of indication bits of the MCS, the MCS used for data can be gradually increased.

[0157] In another example, the corresponding relationship between the MCS and the number of antenna ports (ports) or the number of data streams of the demodulation reference signal (DMRS) can be defined. Since a low number of data streams in data transmission usually means poor channel quality, a lower - order modulation method can be selected, and thus the indication bit of the MCS can be less. Exemplarily, Table 1 shows a corresponding relationship between the number of antenna ports and the MCS.

[0158] Table 1: An example of the corresponding relationship between the number of antenna ports and the MCS

[0159] Antenna port number (port size) MCS 1 0～4 2 5～10 3 11～20 4 21～27

[0160] As shown in Table 1, when the number of antenna ports during data transmission is 1, or the number of data streams is 1, the MCS selection range is MCS0 - MCS4, corresponding to QPSK. When the number of antenna ports during data transmission is 2, or the number of data streams is 2, the MCS selection range is MCS5 - MCS10, and so on.

[0161] Based on the above - mentioned scheme, the corresponding relationship between the number of antenna ports or the number of data streams during data transmission and the MCS can be predefined. Thus, during data transmission, the terminal and the base station can select the corresponding MCS to modulate the data according to this corresponding relationship.

[0162] In another example, one or more timing windows may be indicated in the wake-up signal. For example, the start time of the timing window and the length of the timing window may be indicated in the wake-up signal. For another example, the start time of the timing window and the end time of the timing window may be indicated in the wake-up signal. In this example, the correspondence between the timing window and the MCS may be pre-agreed.

[0163] Exemplarily, referring to Figure 6 , timing window A is associated with MCS1. When the terminal transmits data within timing window A, MCS1 can be used; timing window B is associated with MCS2. When the terminal transmits data within timing window B, MCS2 can be used. In this example, as time goes by, the more information the terminal obtains, such as channel information and beam information, etc., the more the MCS can increase with the passage of time.

[0164] Exemplarily, timing window A may be associated with MCS table 1, and the base station may indicate the MCS used for data transmission within timing window A in MCS table 1. Timing window B may be associated with MCS table 2, and the base station may indicate the MCS used for data transmission within timing window B in MCS table 2.

[0165] It should be noted that the MCS table associated with the timing window may be a part of the MCS table associated in the related art. In this way, through the association relationship between the timing window and the MCS table, the increase of the MCS with time can also be realized.

[0166] Optionally, one or more timing windows indicated by the wake-up signal may also be associated with the transmission bandwidth used for data. That is to say, the base station can configure the active transmission bandwidth used for data for the terminal through the wake-up signal. It can be understood that the active transmission bandwidths associated with different timing windows may be different or the same, and the present application does not make specific limitations.

[0167] In the embodiments of the present application, the data is transmitted progressively, and the control information, such as DCI, may also be transmitted progressively. In one possible case, the variation rule of the number of control resource sets (CORESET) carrying the control information may be the same as the variation rule of the maximum available bandwidth (the first transmission bandwidth) in the data transmission of the first mode. That is to say, the number of control resource sets can increase as the aforementioned first transmission bandwidth increases. In this case, the base station can configure m first transmission bandwidths of different sizes for the terminal through configuration information, such as RRC signaling, as shown in the aforementioned case 2. The base station can configure m groups of control resource sets for the terminal through the 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 to the m first transmission bandwidths one by one. Exemplarily, referring to Figure 7A, the number of control resource sets corresponding to BWP1 can be indicated by configuration information as X, which gradually increases as the BWP increases and can be at most Y. Here, both X and Y are positive integers, and X and Y can be the same or different.

[0168] In another possible case, the variation rule of the size of the control resource set can be the same as the variation rule of the maximum available bandwidth (the second transmission bandwidth) in the nth transmission, that is, the size of the control resource set can increase as the second transmission bandwidth increases. In this case, the base station can, through configuration information such as RRC signaling, configure for the terminal the size and number of the control resource set carrying the control information for scheduling the nth transmission. Exemplarily, refer to Figure 7B , the size and number of the control resource set carrying the control information for scheduling the first transmission, the size and number of the control resource set carrying the control information for scheduling the second transmission, and the size and number of the control resource set carrying the control information for scheduling the third transmission can be indicated to the terminal through configuration information. As Figure 7B shown, as the data is correctly transmitted, the size of the control resource set gradually becomes larger. Optionally, the number of control resource sets gradually becomes smaller.

[0169] Based on the above two possible cases, 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 achieve the progressive transmission of control information.

[0170] Optionally, in the embodiments of this application, the configuration information can also indicate the aggregation level of non-carrier coverage extension (CCE) used for PDCCH blind detection. For example, the aggregation level of the search space is adapted to small data volume blind detection, 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. Exemplarily, 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}. Another example is that the relationship between the channel quality indicator (CQI) and CCE can be defined, as shown in Table 2. The base station can indicate to the terminal through DCI to select the corresponding CCE according to the CQI.

[0171] Table 2: An example of the relationship between a CQI and CCE

[0172] CQI CCE 0～10 16 11～17 4 18～24 2 25～31 1

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

[0174] In a possible implementation, the antenna port can be indicated through DCI. In the embodiments of the present application, the number of data streams in the data transmission of the first mode can only support a fixed number of streams, such as 1 stream, 2 streams, etc., and can be implemented through an antenna port table. Optionally, the DCI may not include code division multiplexing (CDM) information, such as a CDM group. That is to say, the DCI indicates that there is no CDM group in the frequency domain configuration. 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 to say, the number of time domain symbols of DMRS in the antenna port table is a specified number, such as 1.

[0175] Table 3:

[0176]

[0177] It can be understood that the antenna port table shown in Table 3 is part of the antenna port table in the related art and is only shown for illustrative purposes. In the embodiments 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 can be a newly defined table, and the present application does not make specific limitations.

[0178] Optionally, in the first mode, the number of transport blocks (TBs) is a fixed value, such as 1, 2, etc., so as to reduce the overhead of DCI. Based on the MCS and RB mentioned above, the maximum TB size can be determined for indicating data transmission.

[0179] Based on this solution, the number of indication bits of DCI can be reduced, so that the overhead of DCI can be reduced. Therefore, in the first mode, the lengths of DCI may not be the same. Therefore, the base station can fill different lengths of DCI with padding bits to make the lengths of DCI the same. Refer to Figure 8, since the base station can determine how many bits are reduced during the generation of 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 one or more of the angle of multipath, the relative position of the base station and the terminal, the sensing result, the speed of the target user, the position of the target user, bit 0 or bit 1.

[0180] In the embodiments of the present application, the acknowledgment message of the data can also be transmitted progressively. In one possible case, the acknowledgment message, such as ACK and / or non-acknowledgement (NACK), can include one or more of signal-to-noise ratio (SNR), signal-to-interference plus noise ratio (SINR), reference signal receiving power (RSRP), or reference signal receiving quality (RSRQ). It can be understood that the above SINR, SNR, RSRP, and RSRQ can be the measurement results of the signal carrying the data. That is to say, during the downlink transmission process, the terminal can feedback the measurement results of the signal to the base station. Optionally, the acknowledgment message can also include one or more of the indication information of whether the decoding is correct or the reference MCS. Among them, the reference MCS can correspond to the foregoing measurement results.

[0181] Exemplarily, during the downlink data transmission process, if the terminal correctly decodes the received data, the terminal can send an ACK to the base station, and the ACK can indicate to the terminal that the data is correctly decoded. The ACK can also include the measurement results of the signal carrying the data and the reference MCS corresponding to the measurement results. If the terminal does not correctly decode the received data, the terminal can send a NACK to the base station, and the NACK can indicate to the terminal that the data is not correctly decoded. The NACK can also include the measurement results of the signal carrying the data and the reference MCS corresponding to the measurement results.

[0182] In some embodiments, the correspondence between the measurement results and the MCS can be predefined. For example, the correspondence between the SNR and the MCS can be predefined, as shown in Table 4.

[0183] Table 4: An example of the correspondence between an SNR and an MCS

[0184] SNR MCS 0 0 1 1 2 2 3 2 … … 24 27

[0185] 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; when the SNR is 24, the reference MCS can be 27. That is to say, a value of SNR can correspond to a value of MCS. The terminal can carry the information of the reference MCS in the ACK / NACK. The values of SNR described in Table 4 are related to the number of antennas and the 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 measurement of SNR, the terminal can determine the reference MCS through Table 4 and feedback it to the base station through ACK / NACK.

[0186] It can be 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 the SNR value range and the value of MCS. For example, the SNR values 0 to 6 correspond to the MCS value 0, the SNR values 7 to 12 correspond to the MCS value 1, etc. The present application does not make specific limitations. Similarly, the correspondence between SINR, RSRP or RSRQ and MCS can be implemented with reference to Table 4.

[0187] Optionally, the terminal may not carry the information of the reference MCS in the ACK / NACK, but carry the measurement result of the signal carrying the data, such as SNR. In this way, the base station can also determine the reference MCS according to the corresponding relationship shown in Table 4.

[0188] During the uplink transmission process, the base station can measure the signal carrying the data to obtain the measurement result, such as SNR. The base station can determine the reference MCS based on the corresponding relationship shown in Table 4.

[0189] In some embodiments, the base station can determine the MCS used for the next data transmission through the reference MCS in the ACK / NACK. For example, the base station can use the reference MCS as the MCS used for the next data transmission and indicate it to the terminal through DCI. Another example, refer to Figure 9 The base station can determine the MCS used for the next data transmission based on the reference MCS and the measured MCS. Among them, the measured MCS can be the MCS selected based on the measurement feedback of the channel quality indicator (CQI), or can be the MCS feedback based on the environmental information of RF-MAP, or can be the MCS used in the previous transmission.

[0190] Based on the above solution, the base station can determine the MCS used for the next transmission through the measurement result of the signal carrying the data, which is more timely and accurate compared with the MCS adjustment scheme in the related art.

[0191] Optionally, in downlink data transmission, the downlink data demodulation result requires a quick feedback ACK. Therefore, the base station can configure the range of K2 within a specified time slot range in the time domain resource allocation through RRC signaling to reduce the feedback time interval. For example, the range of K2 can be configured as 0 to 5 time slots. Here, K2 represents the time domain interval from receiving the DCI to transmitting the uplink PUSCH of ACK / NACK.

[0192] S303: The terminal determines to transmit data through the second mode.

[0193] This step is optional. Figure 3 It is shown by a dashed line in the figure. Similarly, the base station determines to transmit data through the second mode.

[0194] For example, the terminal can switch from the first mode to the second mode and transmit data through the second mode. Refer to Figure 10 , after receiving the wake-up signal, the terminal can transmit data through the first mode. Among them, in the first mode, the terminal can transmit data in a progressive manner. Optionally, as Figure 10 shown, during this period, the terminal can measure the channel quality and feedback it to the base station through channel state information (CSI).

[0195] In one possible case, the switch from the first mode to the second mode can be determined by the terminal based on the switching condition. It can be understood that the switching condition can be indicated by the base station. For example, the base station can carry the switching condition in the DCI, RRC signaling or paging message. Or, the switching condition can be predefined by the protocol, and this application does not make specific limitations.

[0196] Optionally, the switching condition can be that the measurement result of the signal carrying data is greater than or equal to the first threshold, such as the RSRP is greater than or equal to the first threshold, or the channel quality is greater than or equal to the second threshold.

[0197] In another possible case, the wake-up signal in S301 can indicate the timing duration of a timer, and when the timer expires, the terminal can transmit data through the second mode. For example, after receiving the wake-up signal, the terminal can start the timer and transmit data through the first mode. When the timer expires, the terminal can switch to the second mode and transmit data through the second mode.

[0198] 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 can transmit data through 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 can transmit data through the first mode. Each transmission can be counted as one time, or each correct transmission can be counted as one time, or each time of sending CSI can be counted as one time. Through the counter, when the counter reaches this value, the terminal can switch to the second mode and transmit data through the second mode.

[0199] In another possible scenario, the switch from the first mode to the second mode can be indicated by the base station. For example, the base station can indicate to the terminal to switch from the first mode to the second mode through DCI or RRC signaling. Optionally, in downlink data transmission, the terminal can send demodulation results or measurement results to the base station, and the base station determines whether to perform mode switching. Optionally, in uplink data transmission, the base station can determine whether to perform mode switching based on demodulation results or measurement results, etc.
