Description

Technical Field

[0001] The embodiments of the present invention relate to the field of communications, and more specifically, to a method for transmitting information, 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. The 3rd Generation Partnership Project (3GPP) international standards organization began to develop the fifth generation of mobile communication technology (5-Generation, 5G). 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's island coverage mode. And because a large number of LTE are deployed below 6 GHz, there are few spectrums below 6 GHz available for 5G. Therefore, NR must study spectrum applications above 6 GHz, but high-frequency band coverage is limited and signals fade quickly.

[0003] In the prior art, since the uplink power of the terminal device is limited, and the frequency of the NR spectrum (primary uplink carrier) is high and the propagation loss is high, the uplink coverage is limited. In order to improve the uplink coverage, the LTE spectrum (relatively low frequency) is used as an auxiliary uplink spectrum (that is, there is an auxiliary uplink carrier), which can improve the uplink coverage.

[0004] More specifically, if the reference signal received power (RSRP) of the measured cell is lower than the threshold configured by the system broadcast, the auxiliary uplink carrier is selected to improve the uplink coverage. If the RSRP measured by the terminal device is higher than the threshold configured by the system broadcast, the terminal device can select the primary uplink carrier or the auxiliary uplink carrier.

[0005] However, the loads on the two carriers are different.

[0006] Therefore, if the terminal device cannot reasonably select a carrier for data transmission among the two carriers, it is very likely to cause uplink capacity limitation. Summary of the invention

[0056] Figure 1 This is an example of an application scenario of an embodiment of the present invention.

[0057] like Figure 1 As shown, the terminal device may have one downlink carrier and two uplink carriers (eg Figure 1 Specifically, the first uplink carrier and the downlink carrier may be carriers on the NR high frequency band, and the second uplink carrier may be a carrier on the LTE low frequency band. It should be understood that Figure 1 The terminal device shown as having two uplink carriers is only an exemplary description, and the embodiment of the present invention does not specifically limit it. For example, the terminal device may also support three uplink carriers, and so on.

[0058] It is understandable that the motivation for introducing the second uplink carrier is to improve the uplink coverage of the NR high frequency band.

[0059] Specifically, since the uplink power of the terminal device is limited and the frequency of the NR spectrum (high frequency, high propagation loss) is relatively high, the uplink coverage of NR will be limited. In order to improve the uplink coverage, a method for transmitting data is proposed in an embodiment of the present invention. By using the LTE spectrum (relatively low frequency) as an auxiliary uplink carrier, the uplink coverage effect can be improved.

[0060] For example, the combination of the first uplink carrier and the second uplink carrier can be similar to carrier aggregation (CA) in LTE, except that there is no paired downlink. That is, from the perspective of band combination, the second uplink carrier is a cell with only uplink and no paired downlink, but its uplink is controlled by a certain downlink carrier, that is, when the second uplink carrier is configured, the second uplink carrier is a secondary service cell (SCell) without downlink, and the control of the second uplink carrier depends on the primary service cell (PCell).

[0061] It should be understood that the embodiments of the present invention can be applicable to any communication system including multiple uplinks. For example, the first communication system and the second communication system can be 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.

[0062] Furthermore, the present invention describes various embodiments in conjunction with the network devices (the first to fourth network devices) and the terminal devices.

[0063] The network device may refer to any entity on the network side that is used to send or receive signals. For example, it may be a user equipment of machine type communication (MTC), a base transceiver station (BTS) in GSM or CDMA, a base station (NodeB) in WCDMA, an evolutionary Node B (eNB or eNodeB) in LTE, a base station device in a 5G network, etc.

[0064] The terminal device may be any terminal device. Specifically, the terminal device 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.

[0065] However, for the above Figure 1 In the scenario shown, the selection of the second uplink carrier (auxiliary carrier) is determined based on the signal quality of the downlink carrier measured by the terminal device. For example, if the reference signal received power (RSRP) of the measured cell is lower than the threshold configured by the system broadcast, the auxiliary uplink carrier is selected to improve the uplink coverage. If the RSRP measured by the terminal device is higher than the threshold configured by the system broadcast, the terminal device can select the main uplink carrier or the auxiliary uplink carrier.

[0066] However, since the loads on the two carriers are different, the terminal device needs to reasonably select a carrier for transmitting data between the two carriers, thereby increasing the uplink capacity.

[0067] In order to solve the above technical problems, a method for transmitting data is proposed in an embodiment of the present invention, which enables a terminal device to select a carrier for transmitting data from multiple carriers, thereby balancing the load on multiple uplink carriers that can be used for transmitting data of the terminal device, thereby improving the uplink capacity.

[0068] Figure 2 It is a schematic flow chart of a method for transmitting information according to an embodiment of the present invention.

[0069] Specifically, Figure 2 As shown, the method includes:

[0070] 210. The terminal device receives a first value sent by a network device for the terminal device to select a carrier. For example, the terminal device receives a first value broadcasted by a network device for the terminal device to select a carrier. That is, the first value is sent to the terminal device in the form of broadcast.

[0071] 220. The terminal device determines, according to the first value, a target uplink carrier from a first uplink carrier and a second uplink carrier that can be used by the terminal device for data transmission.

[0072] 230. The terminal device sends uplink data to the network device on the target uplink carrier.

[0073] In short, the terminal device determines the uplink carrier for transmitting data through the first value of the network device. That is, the method of the embodiment of the present invention can control the terminal device to select a carrier for transmitting data from multiple carriers through the network device, thereby balancing the load on multiple uplink carriers of the terminal device that can be used for transmitting data, thereby improving the uplink capacity.

[0074] It should be understood that the signal measurement quality of the terminal device in the embodiment of the present invention may be greater than the threshold value broadcast by the system. Further, the signal measurement quality may be the reference signal receiving power (RSRP) and / or the reference signal receiving quality (RSRQ) measured by the terminal device.

[0075] For example, the first value may directly indicate an uplink carrier used by the terminal device to transmit uplink data. That is, the first value may be an index of the target uplink carrier.

[0076] In one embodiment, before the terminal device determines the target uplink carrier, it can also obtain a second numerical value, and the second numerical value is used to compare the size with the first numerical value. The comparison result of the first numerical value and the second numerical value indicates that the target uplink carrier is the first uplink carrier or the second uplink carrier; then, the terminal device can determine the target uplink carrier according to the above comparison result.

[0077] In one embodiment, the terminal device randomly generates the second value.

[0078] In another embodiment, the terminal device receives the second value sent by the network device, wherein the second value is determined by the network device according to the load conditions of the first uplink carrier and the load conditions of the second uplink carrier.

[0079] For example, if the load of the first uplink carrier is less than the load of the second uplink carrier, the second value is greater than the third value; if the load of the first uplink carrier is greater than or equal to the load of the second uplink carrier, the second value is less than or equal to the third value, wherein the third value is a reference value used by the network device to determine the second value.

[0080] For example, if the load of the first uplink carrier is greater than or equal to the load of the second uplink carrier, the second value is greater than the third value; if the load of the first uplink carrier is less than the load of the second uplink carrier, the second value is less than or equal to the third value, wherein the third value is a reference value used by the network device to determine the second value.

[0081] Further, the value range of the first numerical value, the value range of the second numerical value, and the value range of the third numerical value are all from 0 to 1; or, the value range of the first numerical value, the value range of the second numerical value, and the value range of the third numerical value are all from 0 to 10.

[0082] In other words, assuming that the first value is k, the second value is n, the first uplink carrier is an auxiliary uplink carrier, and the second uplink carrier is a primary uplink carrier. In the embodiment of the present invention, the principle for the network device to determine the second value may be any one of the following principles:

[0083] If the primary uplink carrier is less loaded than the auxiliary uplink carrier, the network device configures a number less than 0.5(5), such as 0.3(3) for the terminal device. If the primary uplink carrier is heavily loaded, the network device configures a number greater than 0.5(5), such as 0.7(7) for the terminal device.

[0084] If the load of the primary uplink carrier is light, the network device configures a number greater than 0.5(5), such as 0.7(7) for the terminal device. If the load of the primary uplink carrier is medium, the network device configures a number less than 0.5(5), such as 0.3(3) for the terminal device.

[0085] Thus, after the terminal device obtains the first value and the second value mentioned above, it can determine the target uplink carrier by comparing the first value and the second value. For example, when the comparison result is that the first value is greater than the second value, it indicates that the target uplink carrier is the first uplink carrier; or when the comparison result is that the first value is less than or equal to the second value, it indicates that the target uplink carrier is the second uplink carrier.

[0086] In other words, assuming that the first value is k, the second value is n, the first uplink carrier is an auxiliary uplink carrier, and the second uplink carrier is a primary uplink carrier. In the embodiment of the present invention, the principle for the terminal device to select the target uplink carrier may be any one of the following principles:

[0087] If n is greater than k, the primary uplink carrier is selected, otherwise the secondary uplink carrier is selected.

[0088] If n is greater than k, the auxiliary uplink carrier is selected, otherwise the primary uplink carrier is selected.

[0089] It should be understood that the embodiment of the present invention does not specifically limit the second value determined by the network device and the combination method of the terminal device determining the target uplink carrier based on the first value and the second value. That is, the principle of the network device determining the second value and the principle of the terminal device determining the target uplink carrier in the embodiment of the present invention can be bound or not. The embodiment of the present invention does not make specific limitations.
