Description

Technical Field

[0001] The embodiments of the present invention relate to the field of communications, and more specifically, to a method for transmitting data, a terminal device and a network device. Background Art

[0002] With people's pursuit of speed, latency, high-speed mobility, energy efficiency and the diversity and complexity of business in future life.

[0003] To this end, the 3rd Generation Partnership Project (3GPP) international standards organization began to develop the fifth generation of mobile communication technology (5-Generation, 5G). The main application scenarios of 5G are: Enhanced Mobile Broadband (eMBB), Ultra-Reliable and Low Latency Communication (URLLC), and massive machine type of communication (mMTC).

[0004] In the early deployment of New Radio (NR), complete NR coverage was difficult to obtain, so the typical network coverage was wide-area Long Term Evolution (LTE) coverage and NR island coverage mode. And because a large number of LTEs are deployed below 6 GHz, there is very little spectrum below 6 GHz available for 5G. Therefore, NR must study spectrum applications above 6 GHz, but high-frequency bands have limited coverage and fast signal fading. In the prior art, in order to protect the initial investment of mobile operators in LTE, a tight interworking working mode between LTE and NR is proposed. Specifically, bandwidth combination is used to support LTE-NR dual connection (DC) data transmission and improve system throughput.

[0005] However, when a terminal device simultaneously operates on two or more carriers in different frequency bands, the uplink signals of these carriers may interfere with the downlink reception signals of certain carriers, thereby reducing the success rate of data transmission.

[0090] Figure 1 It is a schematic diagram of an application scenario of an embodiment of the present invention.

[0091] like Figure 1 As shown, the communication system 100 may include a terminal device 110 and a network device 120. The network device 120 may communicate with the terminal device 110 via an air interface. The terminal device 110 and the network device 120 support multi-service transmission.

[0092] It should be understood that the embodiment of the present invention is only exemplified by the communication system 100, but the embodiment of the present invention is not limited thereto. That is to say, the technical solution of the embodiment of the present invention can be applied to various communication systems, such as: Global System of Mobile communication (GSM) system, Code Division Multiple Access (CDMA) system, Wideband Code Division Multiple Access (WCDMA) system, General Packet Radio Service (GPRS), Long Term Evolution (LTE) system, LTE Time Division Duplex (TDD), Universal Mobile Telecommunication System (UMTS), etc.

[0093] Furthermore, the present invention describes various embodiments in conjunction with network devices and terminal devices.

[0094] The network device 120 may refer to any entity on the network side that is used to send or receive signals, for example, a user equipment of machine type communication (MTC), a base station (Base Transceiver Station, BTS) in GSM or CDMA, a base station (NodeB) in WCDMA, an evolutionary base station (Evolutional Node B, eNB or eNodeB) in LTE, a base station device in a 5G network, etc.

[0095] The terminal device 110 may be any terminal device. Specifically, the terminal device 110 may communicate with one or more core networks via a radio access network (RAN), and may also be referred to as an access terminal, user equipment (UE), user unit, user station, mobile station, mobile station, remote station, remote terminal, mobile device, user terminal, terminal, wireless communication device, user agent or user device. For example, it may be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), a handheld device with wireless communication function, a computing device or other processing device connected to a wireless modem, a vehicle-mounted device, a wearable device, and a terminal device in a 5G network.

[0096] In the early deployment of New Radio (NR) in 5G communication systems, complete NR coverage is difficult to obtain, so the typical network coverage is wide-area Long Term Evolution (LTE) coverage and NR island coverage mode. In addition, since a large number of LTEs are deployed below 6 GHz, there is little spectrum below 6 GHz available for 5G.

[0097] In order to solve the above problems, in the embodiments of the present invention, bandwidth combination can be used to support LTE-NR dual connection (DC) data transmission to improve system throughput. However, when a terminal device simultaneously operates on two or more carriers in different frequency bands, the uplink signals of these carriers may interfere with the downlink reception signals of some carriers, reducing the success rate of data transmission.

[0098] For example, assuming that carrier F1 operates in the low frequency band and carrier F2 operates in the high frequency band, the following three different types of mutual interference may occur:

[0099] The first type of mutual interference is: carrier F1 and carrier F2 are both uplink carriers, and the frequency of a certain order of intermodulation signal (IM) of carrier F1 and carrier F2 overlaps or partially overlaps with the frequency of a downlink signal of a certain carrier F3. Then carriers F1 and F2 interfere with F3. Here F3 may be one of carriers F1 or F2, or another carrier different from F1 / F2 (at this time, the terminal may work on more than two carriers at the same time). For example, the terminal device is configured with LTE carriers with bandwidths (Band) 1 and Band 7, and NR carriers (3400-3800MHz). If the uplink (UL) of band 7 and the UL of NR are transmitted at the same time, the 5th order intermodulation effect generated will affect the downlink (DL) receiver sensitivity of band 1.

[0100] The second type of mutual interference is: carrier F1 is an uplink carrier, carrier F2 is a downlink carrier, and the frequency multiple of carrier F1 overlaps or partially overlaps with the frequency of carrier F2. Then carrier F1 constitutes harmonic interference to carrier F2. For example, the bandwidth of LTE Band 3 is 1710-1785MHz, and its 2nd-order harmonic range is 3420-3570MHz. If a terminal simultaneously performs LTE uplink transmission on band 3 and DL reception on the NR band 3400-3800MHz, the 2nd-order harmonic may interfere with the sensitivity of the NR DL receiver.

[0101] The third type of mutual interference is: carrier F1 is a downlink carrier, carrier F2 is an uplink carrier, and the frequency multiple of carrier F1 overlaps or partially overlaps with the frequency of carrier F2. Then carrier F2 causes harmonic mixing interference to F1. For example, the downlink of LTE Band 3 is 1805-1880MHz, and its 2nd-order harmonic range is 3610-3760MHz. If a terminal simultaneously performs LTE downlink reception on band 3 and uplink transmission on the NR band 3400-3800MHz, the 2nd-order harmonic intermodulation of NR may interfere with the sensitivity of the LTE DL receiver.

[0102] However, regardless of which type of self-interference the terminal device has, the estimation of the severity of the self-interference problem (MSD) is based on the assumption of 23dbm (the maximum transmit power of the terminal). When the terminal device does not operate at the maximum transmit power, the corresponding self-interference will be reduced accordingly (under the same bandwidth assumption). Therefore, reducing the transmit power of the interfering party can alleviate the degree of interference to a certain extent.

[0103] Therefore, an embodiment of the present invention provides a method for transmitting data, which can effectively improve the success rate of data transmission by controlling the uplink transmission power of the terminal device.

[0104] Figure 2 It is a schematic flow chart of a method for transmitting data according to an embodiment of the present invention.

[0105] like Figure 2 As shown, the method includes:

[0106] 210. The network device sends indication information to the terminal device, where the indication information is used by the terminal device to determine a first transmission power of uplink data within a target time unit.

[0107] 220. The terminal device determines a first transmission power according to the indication information.

[0108] 230. The terminal device sends uplink data according to the first transmission power within the target time unit.

[0109] In short, the terminal device receives indication information; the terminal device determines the first transmission power according to the indication information; the terminal device sends uplink data to the first network device according to the first transmission power within the target time unit.

[0110] It should be understood that the terminal device in the embodiment of the present invention is a terminal device that may have self-interference. In order to facilitate the understanding of the solution, the network device used to receive the uplink data sent by the terminal device is referred to as the first network device, and the network device used to send downlink data to the terminal device is referred to as the second network device.

[0111] Specifically, the terminal device can receive downlink data sent by the second network device while sending uplink data to the first network device. At this time, the uplink data generates self-interference to the reception of the downlink data, reducing the demodulation performance of the downlink data. In other words, there is mutual interference between the first channel of the terminal device and the second channel. In other words, the first channel has self-interference.

[0112] In order to solve the above problems, the terminal device in the embodiment of the present invention sends indication information through the network device, so that the terminal device determines the first transmission power used to send uplink data within the target time unit according to the self-interference situation, which can effectively improve the demodulation performance of the downlink data and thus improve the success rate of data transmission.

[0113] It should also be understood that the first transmission power in the embodiment of the present invention may be the maximum transmission power (second transmission power) that the terminal device can support, or it may be the limited transmission power (third transmission power) of the terminal device, and the second transmission power is greater than the third transmission power.

[0114] The third transmit power may be any transmit power less than the second transmit power. Optionally, the terminal device may determine a limited maximum transmit power (i.e., the third transmit power) according to the anti-interference capability of the terminal device, and the limited maximum transmit power is less than the maximum transmit power (i.e., the second transmit power) that the terminal device can support.

[0115] It should be understood that the anti-interference capability of the terminal device can be the transmit power determined by the terminal device according to the internal interference level of the terminal device. In other words, when the terminal device sends uplink data below the limited maximum transmit power, the interference level to the receiving end can be reduced to a level that the receiving end can tolerate. In other words, when the terminal device sends and receives data at the same time, the transmit power should be below the limited maximum transmit power, thereby ensuring that the terminal device can correctly demodulate the received data.

[0116] In an embodiment of the present invention, when the terminal sends data according to the second transmission power, a high-order modulation and coding strategy (MCS) can be adopted to increase the transmission amount of uplink data while ensuring the reliability of the uplink data; when the terminal sends data according to the third transmission power, a low-order modulation and coding strategy (MCS) can be adopted to ensure the reliability of the uplink data.

[0117] In addition, it should be noted that the indication information in the embodiment of the present invention may be information determined by the first network device or the second network device, or information determined by negotiation between the first network device and the second network device. The embodiment of the present invention does not make any specific limitation.

[0118] Further, the indication information is interaction information between the first network device and the second network device. That is, the first network device and the second network device need to interact with the indication information. In other words, if the indication information is determined by the first network device, the first network device needs to send the indication information to the second network device; if the indication information is determined by the second network device, the second network device needs to send the indication information to the first network device.

[0119] The indication information of the embodiment of the present invention is exemplarily described below in conjunction with specific embodiments.

[0120] In one embodiment, the indication information is time division multiplexing mode information of the terminal device in the target time unit, that is, the terminal device can determine the first transmission power according to the time division multiplexing information.

[0121] Specifically, the terminal device receives the time division multiplexing mode information of the terminal device within the target time unit sent by the first network device or the second network device, and the second network device is a network device that sends downlink data to the terminal device; the terminal device determines the first transmission power according to the time division multiplexing mode information.

[0122] For example, when the target time unit is used to receive downlink data and send uplink data at the same time, the first transmission power is less than the maximum transmission power that the terminal device can support. When the target time unit is only used to send uplink data, the first transmission power is the maximum transmission power that the terminal device can support.

[0123] In another embodiment, the indication information includes a bit sequence, the bit sequence includes at least one numerical value, the at least one numerical value is used by the terminal device to determine the transmission power of uplink data in at least one time unit, the at least one time unit includes the target time unit. Optionally, the target time unit includes at least one of a subframe, a time slot, and a symbol.

[0124] In other words, the terminal device can determine, based on the indication information, which time units among the at least one time unit mentioned above can send uplink data according to normal uplink power and which time units can send uplink data according to limited uplink power.

[0125] For example, the at least one value is a bitmap, where each bit represents a time unit. When the corresponding bit is set to 1, it means that the time unit sends uplink data according to the limited uplink power, otherwise it sends at normal power. In other words, when the corresponding bit is set to 0, it means that the time unit sends uplink data according to the limited uplink power, otherwise it sends at normal power.

[0126] It should be understood that the at least one numerical value in the embodiment of the present invention may be used to indicate only one of the at least one time unit, or may be used to indicate a plurality of the at least one time units.

[0127] For example, the at least one time unit may be periodic.

[0128] Furthermore, the indication information also includes timing offset information and period information, and the timing offset information and the period information are used by the terminal device to determine the starting position and / or ending position of the above-mentioned at least one time unit in the time domain.

[0129] In another embodiment, the network device may directly instruct the terminal device on which time units to send uplink data according to the second transmission power, and on which time units to send uplink data according to the third transmission power.

[0130] Specifically, the indication information is used to instruct the terminal device to send uplink data to the first network device according to the second transmission power within the target time unit, or the indication information is used to instruct the terminal device to send uplink data to the first network device according to the third transmission power within the target time unit, and the second transmission power is greater than the third transmission power.

[0131] Furthermore, the second transmission power may be a maximum transmission power that the terminal device can support.

[0132] Optionally, the terminal device may obtain the indication information by receiving downlink control information DCI sent by the first network device, for example, the DCI includes the indication information.

[0133] It should be understood that the main purpose of the embodiment of the present invention is that the network device sends indication information to the terminal device so that the terminal device determines the transmission power for sending uplink data. That is to say, the above indication information is only an exemplary description of the embodiment of the present invention, and the embodiment of the present invention is not limited thereto.
