Description

Technical Field

[0001] This application relates to the field of communication technology, and in particular to an uplink data transmission method and apparatus. Background Technology

[0002] In 5G new wireless (5 th In the 5G-NR era, to support non-standalone (NSA) network architecture, user equipment (UE) possesses two complete sets of transmission resources, enabling dual uplink transmission. Dual uplink transmission refers to the UE's two transmission links simultaneously transmitting on the same carrier. Because the UE has two sets of uplink transmission resources, it becomes possible for the base station to allocate two different carriers to the UE for uplink transmission, thus achieving inter-band dual transmission. Inter-band dual transmission means that the UE can transmit on two different uplink carriers. In this implementation, the UE allocates its two sets of transmission resources to two different carriers, achieving dynamic uplink data transmission.

[0003] With the introduction of uplink carrier switching technology, UEs can now support uplink dual-transmission and cross-band dual-transmission modes. This means the UE can switch one set of transmission resources between two carriers, or use two sets of transmission resources on one carrier for uplink transmission. However, current uplink carrier switching technology only supports uplink modes with one fixed carrier transmitting twice and another fixed carrier transmitting once, and cannot support more uplink modes. Summary of the Invention

[0004] This application provides an uplink data transmission method and apparatus, which can distinguish different uplink modes and perform uplink data transmission according to the configured uplink mode when the UE has the capability to transmit twice on two carriers.

[0005] In a first aspect, the present embodiment provides an uplink data transmission method, which comprises: receiving, by a network device, a capability message from a user equipment, the capability message being used to indicate an uplink mode supported by the user equipment, the uplink mode being an uplink mode of a first carrier and a second carrier of the user equipment; and sending, by the network device, a configuration message to the user equipment, the configuration message comprising the uplink mode. In this embodiment, when the user equipment supports multiple uplink modes, the user equipment can report the uplink mode supported by the user equipment to the network device through the capability message, wherein the uplink mode is an uplink mode of a first carrier and a second carrier of the user equipment. The network device determines the uplink mode supported by the user equipment according to the capability message, generates a configuration message, and sends the configuration message to the user equipment. After receiving the configuration message, the user equipment performs uplink data transmission by using the uplink mode comprised in the configuration message. That is, by defining the uplink mode supported by the user equipment in advance, and making the network device know the uplink mode supported by the user equipment through the reporting mode, the network device can configure the available uplink mode for the user equipment, so that the user equipment can switch between different uplink modes, and the uplink data transmission efficiency is improved.

[0006] In a possible implementation manner of the first aspect, the uplink mode can comprise one or more of the following: an uplink mode in which the first carrier allows scheduling two transmissions and the second carrier allows scheduling one transmission, an uplink mode in which the first carrier allows scheduling one transmission and the second carrier allows scheduling two transmissions, and an uplink mode in which the first carrier and the second carrier both allow scheduling two transmissions.

[0007] In a possible implementation manner of the first aspect, the method further comprises: generating, by the network device, the configuration message according to the capability message. Specifically, after obtaining the capability message, the network device can determine the uplink mode supported by the user equipment according to the capability message, and then generate the configuration message according to the uplink mode supported by the user equipment. The configuration message is used to indicate that the user equipment performs uplink data transmission by using the uplink mode comprised in the configuration message.

[0008] In a possible implementation manner of the first aspect, the method further comprises: determining, by the network device, the uplink mode supported by the user equipment according to a preset rule. Specifically, when the uplink mode supported by the user equipment is not reported through the capability message, the network device can directly determine the uplink mode according to the preset rule, so that the uplink mode supported by the user equipment can be more comprehensively obtained. The preset rule is used to indicate that the first carrier or the second carrier is a carrier allowing scheduling two transmissions.

[0009] With reference to the first aspect, in a possible implementation manner, the network device determines the uplink mode supported by the user equipment according to the preset rule, including: the network device determines the uplink mode according to a target carrier corresponding to the preset rule, the uplink mode being used to indicate that the target carrier is an uplink mode allowing scheduling of two transmissions and another carrier is an uplink mode allowing scheduling of one transmission, the target carrier being the first carrier or the second carrier. In this implementation manner, the network device determines the target carrier corresponding to the preset rule as a carrier allowing scheduling of two transmissions, and another carrier as a carrier allowing scheduling of one transmission, thereby determining the uplink mode supported by the user equipment. When the target carrier is the first carrier, the network device determines the uplink mode as the first carrier allowing scheduling of two transmissions and the second carrier allowing scheduling of one transmission. When the target carrier is the second carrier, the network device determines the uplink mode as the second carrier allowing scheduling of two transmissions and the first carrier allowing scheduling of one transmission.

[0010] With reference to the first aspect, in a possible implementation manner, the target carrier can be a carrier with a higher frequency, a carrier used for time division duplexing, or a carrier reported by the user equipment.

[0011] With reference to the first aspect, in a possible implementation manner, when the uplink mode included in the configuration message is in an inactive state, the method further includes: the network device sends an activation message to the user equipment, the activation message including an uplink mode to be activated. The uplink mode to be activated is the uplink mode in the configuration message, and the activation message is used to indicate that the uplink mode is in an active state, so that the user equipment performs uplink data transmission by using the uplink mode in the active state. In this implementation manner, when the uplink mode configured by the network device for the user equipment is in an inactive state, the network device can send an activation message to the user equipment to activate the configured uplink mode. The uplink mode to be activated in the activation message can be one or more.

[0012] With reference to the first aspect, in a possible implementation manner, when there are at least two uplink modes in an active state, the method further includes: the network device sends a control message to the user equipment, the control message including a target uplink mode, and the target uplink mode being used to instruct the user equipment to perform uplink data transmission by using the target uplink mode. In this implementation manner, when there are at least two uplink modes in an active state, the network device can instruct the user equipment to perform uplink data transmission by using the target uplink mode by sending a control message.

[0013] With reference to the first aspect, in a possible implementation manner, the method further includes: reserving a switching time slot by the network device according to a current uplink mode used by the user equipment and a switching time corresponding to the uplink mode. In the implementation manner, different uplink modes each include a first carrier and a second carrier, and the user equipment uses the uplink mode to perform uplink data transmission, which involves switching between different carriers. When the user equipment performs carrier switching, to ensure that uplink data is not lost, the network device does not schedule the user equipment to perform uplink data transmission in the switching time. Specifically, the capability message sent by the user equipment can further include the switching time corresponding to each uplink mode, and the switching time indicates a time used by the user equipment to perform switching between the first carrier and the second carrier. The network device determines the switching time corresponding to each uplink mode according to the capability message, and then ensures that the user equipment is not scheduled to perform uplink data transmission in the switching time.

[0063] To facilitate understanding of the technical solutions provided by the embodiments of the present application, the technical terms involved in the embodiments of the present application will be described first.

[0064] Two uplink transmissions (2Tx up link transmission): refers to two transmission links using the same uplink carrier to transmit data at the same time, mainly applied to uplink multi-input multi-output (UL MIMO), transmit diversity, and two-port sounding reference signal (SRS) in downlink MIMO enhancement. Among them, UL MIMO refers to the network device scheduling the user equipment to transmit different data packets on two sets of transmission links using the same carrier. Transmit diversity refers to the network device scheduling the user equipment to transmit the same data packet on two sets of transmission links using the same carrier to enhance the anti-interference of the signal. Two-port SRS in downlink MIMO enhancement refers to the network device scheduling the user equipment to transmit SRS through the ports corresponding to the two sets of transmission links respectively, so that the network device can determine the channel quality of the transmission link according to the SRS transmitted by each transmission link port.

[0065] One uplink transmission: refers to only one transmission link using an uplink carrier to transmit data.

[0066] For ease of understanding, refer to the application scenario schematic diagram as shown in Figure 1 As shown in Figure 1 When the UE performs two transmissions at 3.5 GHz, power supply 2 will provide power for the 3.5 GHz transceiver, and the 3.5 GHz carrier generated by phase-locked loop 1 will be sent to radio frequency module 1 and radio frequency module 2 respectively. Radio frequency module 1 and radio frequency module 2 respectively modulate the baseband signals sent by the digital-to-analog converters corresponding to them using the 3.5 GHz carrier to obtain radio frequency signals. The radio frequency signal output by radio frequency module 1 is amplified and then transmitted through the transmitter corresponding to the 3.5 GHz carrier corresponding to it. The radio frequency signal output by radio frequency module 2 is amplified and then transmitted through the transmitter corresponding to the 3.5 GHz carrier corresponding to it. When the UE performs one transmission at 1.8 GHz, power supply 2 will provide power for the 1.8 GHz transceiver, and the 1.8 GHz carrier generated by phase-locked loop 2 will be sent to radio frequency module 2. Radio frequency module 2 will modulate the baseband signal sent by digital-to-analog converter 2 using the 1.8 GHz carrier to obtain a radio frequency signal. The radio frequency signal output by radio frequency module 2 is amplified and then transmitted through the transmitter corresponding to the 1.8 GHz carrier corresponding to it.

[0067] Embodiments of the present application can be applied to architectures such as supplemental uplink (SUL), uplink carrier aggregation (UL CA), and LTE-NR dual connectivity (EN-DC). To facilitate understanding of the specific forms of the above architectures, the above three architectures will be described below in conjunction with the accompanying drawings.

[0068] With the development of 5G services, it is a new demand and challenge for the network to greatly improve the uplink experience and shorten the latency while keeping the downlink experience unchanged. However, the shortcoming of wireless network coverage is in the uplink. For example, the base station power can reach 200W, and when the base station transmits a signal to the mobile phone, the downlink coverage distance is not a concern. However, the transmission power of the mobile phone is only 0.2W, and when the mobile phone transmits a signal to the base station, the uplink coverage distance is limited. Moreover, the higher the frequency band, the shorter the coverage distance. The 3.5G frequency band has 50% less coverage than the 4G main frequency band 1.8G / 2.1G frequency band. In order to achieve high speed of 5G while also considering uplink coverage, some practical solutions are proposed. For example, SUL, UL CA, and EN-DC.

[0069] Among them, SUL: A cell (Cell) usually contains an uplink carrier (uplink carrier) and a downlink carrier (downlink carrier), and the uplink carrier and the downlink carrier are in the same frequency band. However, in the 5G era, the frequency used is relatively high, and the higher the frequency band, the greater the signal transmission loss. Since the transmission power of the UE is limited, this will result in limited uplink coverage of the UE. Therefore, the industry has proposed SUL technology to ensure the uplink coverage of the UE by providing a supplemental uplink (usually in a low frequency band, such as an LTE frequency band). The original uplink corresponding to the UE is called the normal uplink (NUL), and the supplemental uplink is called SUL. Generally, the frequency point (for example, 1.8GHz) corresponding to SUL is lower than that of NUL, and the signal loss is smaller, thereby ensuring the uplink coverage of the UE. The UE can dynamically select a transmission link between NUL and SUL. For ease of understanding, as shown in the application scenario diagram, Figure 2 As shown in the application scenario diagram, at the near midpoint of the cell, the UE uses the 3.5GHz carrier for data reception and transmission in uplink and downlink. At the far point of the cell, SUL is activated, and the UE switches the uplink task from the 3.5GHz carrier to the 1.8GHz carrier.

[0070] Carrier aggregation, as the name implies, is to aggregate multiple carriers for transmission. Since each operator can only get a limited frequency band, which is not necessarily continuous, if each UE can only use a few frequency bands, the rate of the UE will be limited. If the UE supports carrier aggregation, several completely independent carriers are bundled together for the UE to use, improving the UE's rate. For ease of understanding, see the application scenario diagram shown in Figure 3 In this embodiment, 3.5 GHz carrier and 2.1 GHz carrier aggregation are taken as an example. At the near-middle point of the cell, the UE can simultaneously use the 3.5 GHz carrier and the 2.1 GHz carrier for uplink data transmission. That is, at the near-middle point of the cell, one of the two transmission links of the UE uses the 3.5 GHz carrier for uplink data transmission, and the other transmission link uses the 2.1 GHz carrier for uplink data transmission. When the UE supports 3.5 GHz carrier uplink two-transmission, or at the near-middle point of the cell, the two transmission links of the UE can both use the 3.5 GHz carrier for uplink data transmission. At the far point of the cell, the UE uses the 2.1 GHz carrier for uplink data transmission. When the UE supports 2.1 GHz uplink one-transmission, one of the transmission links of the UE uses the 2.1 GHz carrier for uplink data transmission, and when the UE supports 2.1 GHz uplink two-transmission, the two transmission links of the UE can both use the 2.1 GHz carrier for uplink data transmission.

[0071] EN-DC, namely non-standalone networking architecture, is that the UE can simultaneously use 4G and 5G for communication. For ease of understanding, see the application scenario diagram shown in Figure 4 In the common coverage range of 4G and 5G (near-middle point), the UE can simultaneously connect 5G 3.5 GHz (TDD mode) and 4G 2.1 GHz (FDD mode). When the UE moves out of the coverage range of 5G (far point), the UE disconnects 5G and uses 4G for uplink and downlink communication.

[0072] With the proposal of the uplink carrier switching technology, the UE under the SUL, UL CA or EN-DC configuration can switch a set of transmission resources between two carriers, and one carrier can use two sets of transmission resources. See the SUL-based uplink carrier switching diagram shown in Figure 5 In the t1 time period, the UE can use the carrier corresponding to the SUL for uplink data transmission and use the carrier corresponding to the NR downlink (DL) for downlink data reception. When the carrier switching time is reached, the UE does not perform uplink data transmission within the time interval T. After the UE completes the carrier switching, the UE will use the carrier corresponding to the NUL for uplink data transmission in the t2 time period. When the carrier switching time is reached again, the UE performs uplink carrier switching, and continues to use the carrier of the SUL for uplink data transmission and uses the carrier corresponding to the NR DL for downlink data reception in the t3 time period.Figure 5 As shown in the figure, the SUL corresponds to a set of transmission links, and the NUL corresponds to two sets of transmission links, that is, the carrier corresponding to the SUL can perform uplink data transmission on one set of transmission links, and the carrier corresponding to the NUL allows uplink data transmission on two sets of transmission links at the same time.

[0073] Referring to Figure 6 As shown in the figure, the uplink carrier switching based on EN-DC, in the t1 time period, the UE can perform uplink data transmission by using the carrier corresponding to the LTE UL, and perform downlink data reception by using the carriers corresponding to the NDL and the LTE DL. When the carrier switching time is reached, the UE does not perform uplink data transmission in the time interval T. After the UE completes the carrier switching, in the t2 time period, the UE performs uplink data transmission by using the carrier corresponding to the NUL. Since the carrier of the NUL performs two transmissions in the t2 time period, the UE no longer performs uplink data transmission by using the carrier of the LTE UL.

[0074] In the evolution of the UE, a stronger implementation is that the UE can support uplink two transmissions on two carriers, for example, supporting UL MIMO on both 1.8GHz and 3.5GHz. The uplink carrier switching will continue to evolve to realize the switching between two transmission carriers and two transmission carriers. For example Figure 7 As shown in the figure, the UE internal structure diagram, the 3.5GHz carrier generated by the phase-locked loop 1 can be sent to the radio frequency module 1 and the radio frequency module 2 respectively, to realize the uplink two transmissions of the 3.5GHz carrier. The 1.8GHz carrier generated by the phase-locked loop 2 can be sent to the radio frequency module 1 and the radio frequency module 2 respectively, to realize the uplink two transmissions of the 1.8GHz carrier. The UE can be scheduled by the base station to realize the switching between the 1.8GHz carrier and the 3.5GHz carrier.

[0075] However, the current uplink carrier switching only supports the switching between one transmission carrier and two transmission carriers of the UE. When the UE has two transmission capabilities on two different carriers, for example, allowing scheduling two transmissions on a first carrier and allowing scheduling one transmission on a second carrier, allowing scheduling one transmission on a first carrier and allowing scheduling two transmissions on a second carrier, or allowing scheduling two transmissions on both the first carrier and the second carrier. Since the current system cannot distinguish the above different uplink modes, the base station cannot configure the corresponding uplink mode for the UE, thereby affecting the uplink data transmission of the UE.

[0076] Based on the above problems, for the UE having the capability of performing two transmissions on two different carriers, an uplink data transmission method is provided, which predefines the uplink mode supported by the UE, realizes the distinction and correct configuration of different uplink modes by the base station and the UE, and further guarantees that the UE can perform uplink data transmission by using the uplink mode configured by the base station.

[0077] Embodiments of the present application relate to a user equipment. The user equipment can be a device that contains a wireless transceiver function and can cooperate with a network equipment to provide communication services for users. Specifically, the user equipment can refer to an access terminal, a subscriber unit, a subscriber station, a mobile station, a mobile, a remote station, a remote terminal, a mobile device, a user terminal, a terminal, a wireless communication device, a user agent or a user apparatus. For example, the user equipment can 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, a user equipment in a 5G network or a network after 5G, etc.

[0079] For ease of understanding, the uplink data transmission method provided by the embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0080] Referring to Figure 8 , the figure is a flow chart of an uplink data transmission method provided by an embodiment of the present application, as Figure 8 indicated, the method can include:

[0081] S801: The user equipment sends a capability message to the network equipment, the capability message being used to indicate an uplink mode supported by the user equipment.

[0082] In this embodiment, the user equipment can send a capability message to the network equipment to report the supported uplink mode through the capability message. The uplink mode is the uplink mode of the first carrier and the second carrier of the user equipment. For example, the uplink mode can include one or more of the following: the first carrier allows scheduling two transmissions and the second carrier allows scheduling one transmission, the first carrier allows scheduling one transmission and the second carrier allows scheduling two transmissions, and the first carrier and the second carrier both allow scheduling two transmissions. The first carrier can be a higher frequency corresponding carrier or a lower frequency corresponding carrier.

[0083] The first carrier allows scheduling two transmissions means that two transmission links of the user equipment can simultaneously perform uplink data transmission using the first carrier. The first carrier allows scheduling one transmission means that one transmission link of the user equipment performs uplink data transmission using the first carrier. The second carrier allows scheduling two transmissions means that two transmission links of the user equipment can simultaneously perform uplink data transmission using the second carrier. The second carrier allows scheduling one transmission means that one transmission link of the user equipment performs uplink data transmission using the second carrier.

[0084] To facilitate the network equipment to identify the supported uplink mode of the user equipment through the capability message, the mode allowed to be scheduled by the first carrier and the second carrier of the user equipment can be defined in advance. For example, the uplink mode in which the first carrier allows scheduling two transmissions and the second carrier allows scheduling one transmission is defined as the first uplink mode, the uplink mode in which the first carrier allows scheduling one transmission and the second carrier allows scheduling two transmissions is defined as the second uplink mode, and the uplink mode in which the first carrier and the second carrier both allow scheduling two transmissions is defined as the third uplink mode. Of course, the mode allowed to be scheduled by the first carrier and the second carrier of the user equipment can also be defined in other forms, which are not listed one by one in this embodiment.

[0085] When the user equipment supports any one or more of the above uplink modes, an identifier corresponding to the supported uplink mode of the user equipment can be added in the capability message. For example, different uplink modes are identified by using binary. The capability message can include a 3-bit binary identifier field, such as “xxx”. When the user equipment supports the first uplink mode, the corresponding field in the capability message is set to “001”. When the user equipment supports the second uplink mode, the corresponding field in the capability message is set to “010”. When the user equipment supports the third uplink mode, the corresponding field in the capability message is set to “100”. When the user equipment supports the first uplink mode and the second uplink mode, the corresponding field in the capability message is set to “011”. When the user equipment supports the first uplink mode and the third uplink mode, the corresponding field in the capability message is set to “101”. When the user equipment supports the second uplink mode and the third uplink mode, the corresponding field in the capability message is set to “110”. When the user equipment supports all three uplink modes, the corresponding field in the capability message is set to “111”.

[0086] S802: The network device sends a configuration message to the user device, and the configuration message includes the uplink mode.

[0087] In this embodiment, after obtaining the uplink mode supported by the user device, the network device generates a configuration message according to the uplink mode supported by the user device, and the configuration message includes the uplink mode. The configuration message is used to instruct the user device to perform uplink data transmission by using the uplink mode included in the configuration message.

[0088] When the uplink mode supported by the user device includes multiple uplink modes, the network device can include all the uplink modes supported by the user device in the configuration message, or include part of the uplink modes supported by the user device. When the configuration message includes part of the uplink modes, before generating the configuration message, the network device can select the uplink mode configured for the user device from the uplink modes reported by the user device according to a pre-set selection rule, and then generate the configuration message according to the selected uplink mode. Specifically, the network device can send the configuration message to the user device through radio resource control (RRC) signaling.

[0089] In some embodiments, the network device can also send a de-configuration message to the user device through RRC signaling to cancel the uplink mode previously configured by the network device for the user device.

[0090] S803: The user device performs uplink data transmission by using the uplink mode in the configuration message.

[0091] In this embodiment, after receiving the configuration message sent by the network device, the user device can perform uplink data transmission by using the uplink mode included in the configuration message.

[0092] It can be understood that when the user device can directly perform uplink data transmission by using the uplink mode in the configuration message, it indicates that the uplink mode is in an activated state. If the uplink mode in the configuration message is in a non-activated state, the user device will receive an activation message from the network device, and the activation message includes the uplink mode to be activated. The uplink mode to be activated included in the activation message should be the uplink mode in the configuration message. That is, the activation message is used to activate the uplink mode included in the configuration message, so that the uplink mode is in the activated state.

[0093] Specifically, the network device can send the activation message to the user device by using a medium access control (MAC) control element message, so as to activate the uplink mode configured by the network device for the user device, and then enable the user device to perform uplink data transmission by using the activated uplink mode.

[0094] In some embodiments, the network device can further send a deactivation message to the user device by using the MAC control element message, wherein the deactivation message comprises an uplink mode which has been in an activation state. After receiving the deactivation message, the user device will make the uplink mode in a non-activation state, thereby achieving deactivation.

[0095] In some embodiments, when the configuration message comprises at least two uplink modes in an activation state or the network device activates at least two uplink modes by using the activation message, in order to make the user device perform uplink data transmission by using one of the uplink modes, the network device can further instruct the user device to perform uplink data transmission by using a target uplink mode included in the control message by sending the control message. The target uplink mode is one of the uplink modes included in the configuration message. After receiving the control message sent by the network device, the user device can determine the target uplink mode according to the control message, and then perform uplink data transmission by using the target uplink mode. Specifically, the network device can send the control message to the user device by using the DCI message, so that the user device performs uplink data transmission by using the target uplink mode.

[0096] In some embodiments, the network device can periodically send the control message to the user device, so as to control the user device to dynamically switch among different activated uplink modes by using the control message. For example, the network device configures a first uplink mode and a second uplink mode for the user device, in a t1 time period, the user device performs uplink data transmission by using the first uplink mode according to the DCI message sent by the network device; in a t2 time period, the user device performs uplink data transmission by using the second uplink mode according to the DCI message sent by the network device.

[0097] In some embodiments, when the configuration message sent by the network device comprises only one uplink mode and the uplink mode is in an activation state, the user device directly performs uplink data transmission by using the uplink mode in the configuration message after receiving the configuration message. In order to make the user device switch among different modes supported by the user device, the network device can periodically send the configuration message to instruct the user device to perform uplink data transmission by using the uplink mode included in the configuration message, thereby achieving switching of the uplink mode and improving data transmission efficiency.

[0098] As known from the above, each uplink mode includes scheduling of the first carrier and the second carrier, and further involves switching between the first carrier and the second carrier. When the user equipment performs carrier switching, in order to ensure that uplink data is not lost, the network device does not schedule the user equipment for uplink data transmission within the switching time. Specifically, the capability message sent by the user equipment can further include switching time corresponding to each uplink mode, which indicates the time used by the user equipment for switching between the first carrier and the second carrier. The network device determines the switching time corresponding to each uplink mode according to the capability message, and further ensures that the user equipment is not scheduled for uplink data transmission within the switching time.

[0099] It should be noted that although each of the above uplink modes includes the first carrier and the second carrier, the time used by the user equipment for switching between the first carrier and the second carrier can be different in different modes. Therefore, when multiple uplink modes are included in the capability message, the capability message can further include switching time corresponding to each uplink mode.

[0100] The user equipment performs uplink data transmission using the uplink mode in the configuration message, specifically including: the user equipment determines, according to the scheduling message sent by the network device, to use the first carrier or the second carrier in the uplink mode for uplink data transmission in the current time period or in the future time period. The scheduling message is used to instruct the user equipment to use a target carrier for uplink data transmission, and the target carrier is the first carrier or the second carrier. For example, the network device configures the user equipment with an uplink mode in which the first carrier allows scheduling of two transmissions and the second carrier allows scheduling of one transmission. The scheduling message sent by the network device at the first time includes the target carrier as the first carrier, and the user equipment uses the first carrier for uplink data transmission on two transmission links. The scheduling message sent by the network device at the second time includes the target carrier as the second carrier, and the user equipment uses the second carrier for uplink data transmission on one transmission link. The user equipment does not perform data transmission within the time period for switching from the first carrier to the second carrier.

[0101] As known from the above embodiment, the uplink mode supported by the user equipment specifically includes three different uplink modes, and in actual application, the user equipment will support an uplink mode in which both the first carrier and the second carrier allow scheduling of two transmissions, and only support one of the uplink mode in which the first carrier allows scheduling of two transmissions and the second carrier allows scheduling, or the uplink mode in which the first carrier allows scheduling of one transmission. That is, the user equipment supports the third uplink mode and the first uplink mode, or supports the third uplink mode and the second uplink mode. At this time, the network device can determine the uplink mode supported by the user equipment in the following manner.

[0102] Referring to Figure 9FIG. 6 is a flowchart illustrating another method for uplink data transmission according to an embodiment of the present application. As shown in FIG. 6, the method can include the following steps. Figure 9

[0103] S901: The network device receives a capability message from the user equipment, the capability message being used to indicate an uplink mode supported by the user equipment.

[0104] In this embodiment, the uplink mode supported by the user equipment and indicated by the capability message is the uplink mode in which both the first carrier and the second carrier allow scheduling of two transmissions. The specific implementation of S901 can refer to S801.

[0105] S902: The network device determines the uplink mode supported by the user equipment according to a preset rule.

[0106] In this embodiment, the network device can determine, according to the preset rule, another uplink mode supported by the user equipment in addition to the uplink mode supported by the user equipment in S901. The other uplink mode can be one of the uplink mode in which the first carrier allows scheduling of two transmissions and the second carrier allows scheduling of one transmission, or the uplink mode in which the first carrier allows scheduling of one transmission and the second carrier allows scheduling of two transmissions. The preset rule is used to indicate that the first carrier or the second carrier is the carrier allowing scheduling of two transmissions.

[0107] In some embodiments, the network device can determine, according to the preset rule, the uplink mode corresponding to a target carrier, the uplink mode indicating that the target carrier is the carrier allowing scheduling of two transmissions and the other carrier is the carrier allowing scheduling of one transmission. The target carrier is the first carrier or the second carrier. Specifically, the target carrier can be the carrier with a higher frequency among the first carrier and the second carrier, can be the carrier with a lower frequency among the first carrier and the second carrier, can be the carrier used for time division duplexing among the first carrier and the second carrier, or can be the carrier reported by the user equipment, etc. When the target carrier is the carrier reported by the user equipment, the user equipment can report the target carrier through the capability message. That is, the capability message includes the target carrier.

[0108] It should be noted that after the network device determines the uplink mode supported by the user equipment according to the preset rule, the network device also needs to obtain the switching time corresponding to the uplink mode. In this case, the user equipment can send a message including the switching time to the network device, and the network device can determine, after receiving the message, that the switching time included in the message is the switching time corresponding to the uplink mode determined by the network device.

[0109] In this embodiment, S901 can be performed before S902, or S901 and S902 can be performed simultaneously.

[0110] S903: The network device sends a configuration message to the user equipment.

[0111] ​In the embodiment, after the network device obtains the supported uplink mode of the user equipment, a configuration message is generated and sent to the user equipment. The uplink mode included in the configuration message is determined by the network device according to the capability message and preset rules.

[0112] S904: The user equipment performs uplink data transmission by using the uplink mode in the configuration message.

[0113] In the embodiment, after the user equipment receives the configuration message, the user equipment performs uplink data transmission by using the uplink mode included in the configuration message. The specific implementation of S904 can refer to S803.

[0114] Specifically, the configuration message can include one or two uplink modes. When the configuration message includes one uplink mode and the uplink mode is in an activated state, the user equipment performs uplink data transmission by using the uplink mode after receiving the configuration message. When the configuration message includes one uplink mode and the uplink mode is in an inactivated state, the network device sends an activation message to the user equipment to activate the uplink mode in the configuration message, and then the user equipment performs uplink data transmission by using the activated uplink mode.

[0115] When the configuration message includes two uplink modes and both of the uplink modes are in activated states, the network device can also send a control message to notify the user equipment to perform uplink data transmission by using the target uplink mode included in the control message. When the configuration message includes two uplink modes and both of the uplink modes are in inactivated states, the network device activates the uplink modes in the configuration message by sending an activation message to the user equipment. Specifically, the activation message can activate one or two uplink modes. When two uplink modes are activated, the network device can specify the user equipment to perform uplink data transmission by using the target uplink mode by sending a control message.

[0116] Based on the uplink output transmission method provided in the above embodiments, the user equipment and the network device provided in the embodiments of the present application will be described below with reference to the accompanying drawings.

[0154] When the communication device is a user equipment, Figure 14 A structural schematic diagram of a user equipment provided by the embodiments of the application is provided, for the convenience of understanding, a mobile phone is taken as an example for illustration. As shown in Figure 14As shown, the user equipment can include a processor, a memory, a radio frequency circuit, an antenna, and an input and output device. The processor is mainly used for processing communication protocols and communication data, controlling terminal equipment, executing software programs, processing data of software programs, etc. The memory is mainly used for storing software programs and data.

[0155] When data needs to be sent, the processor performs baseband processing on the data to be sent, and outputs the baseband signal to the radio frequency circuit. The radio frequency circuit performs radio frequency processing on the baseband signal, and transmits the radio frequency signal in the form of electromagnetic waves through the antenna. When data is sent to the user equipment, the radio frequency circuit receives the radio frequency signal through the antenna, converts the radio frequency signal into a baseband signal, and outputs the baseband signal to the processor. The processor converts the baseband signal into data and processes the data. For the sake of illustration, Figure 14 In the embodiment of the present application, only one memory and one processor are shown. In actual user equipment products, there can be one or more processors and one or more memories. The memory can also be referred to as a storage medium or a storage device, etc. The memory can be independent of the processor or integrated with the processor.

The processing unit 1420 is configured to perform S902 in Figure 9 , and / or the processing unit 1420 is further configured to perform other processing steps at the user equipment side in the embodiments.

[0161] When the communication apparatus in the embodiments is a user equipment, the apparatus can refer to the device shown in Figure 15 . As an example, the device can perform functions similar to the processor 1310 in Figure 13 . In Figure 15 , the device includes a processor 1510, a transmitting data processor 1520, and a receiving data processor 1530. The processing module 710 in the above embodiments can be the processor 1510 in Figure 15 , and perform corresponding functions.
