[0002] Mobile communication systems can use carrier aggregation (CA) mechanisms to increase signal transmission rates. For example, downlink carrier aggregation can increase downlink reception rates.

[0003] In the current carrier aggregation scenario, there is a problem of inability to flexibly use spectrum resources. Summary of the Invention

[0004] The embodiments of the present application provide an information transmission method and a communication device for achieving flexible use of spectrum resources.

[0005] To solve the above technical problems, the embodiments of the present application provide the following technical solutions:

[0007] In the above solution, the first device first receives first configuration information from the second device. The second device can indicate, through the first configuration information, that T uplink carriers are configured for the first device. At least one element in the value set of T is a positive integer greater than L. For example, the value of T can be greater than the value of L. L is the maximum number of uplink carriers that the first device can simultaneously perform uplink transmission. L can represent the maximum number of uplink carriers that the first device can use when performing simultaneous uplink transmission, that is, the first device can use a maximum of L uplink carriers for uplink concurrent transmission. After the first device determines that the second device configures T uplink carriers for the first device, the first device can determine N uplink carriers from the T uplink carriers, that is, the first device can select carriers from the T uplink carriers. T can be greater than L, so the first device can select carriers from more carriers that exceed the maximum number of uplink carriers for simultaneous transmission of the first device. N is a positive integer less than or equal to L. For example, the value of N is less than or equal to the value of L. Finally, the first device sends information in the N uplink carriers, thereby realizing information transmission between the first device and the second device. In the embodiment of the present application, the first device has the ability to flexibly select carriers among more carriers beyond its uplink concurrency capability, so that the second device can configure more uplink carriers for the first device, and the first device can flexibly select carriers among more carriers, so that the first device can achieve flexible use of spectrum resources.

[0008] In one possible implementation, the method further includes: reporting first capability information to the second device; wherein the first capability information is used to indicate that the first device is capable of determining an uplink carrier for sending information from more than the L uplink carriers; and / or, the first capability information is used to indicate that the first device is capable of supporting the determination of an uplink carrier for sending information from a maximum of S uplink carriers, and at least one element in the value set of S is a positive integer greater than the L; and / or, the first capability information is used to indicate the L. In the above scheme, the first device generates the first capability information and sends the first capability information to the second device.

In the above scheme, the first device has the ability to flexibly select carriers in more carriers than its downlink concurrency capability, so that the second device can configure more downlink carriers for the first device, and the first device can flexibly select carriers in more carriers, so that the first device can achieve flexible use of spectrum resources.

[0010] In one possible implementation, the method further includes: sending second capability information to the second device; wherein the second capability information is used to indicate that the first device can determine a downlink carrier for receiving information from more than the K downlink carriers; and / or, the second capability information is used to indicate that the first device can determine a downlink carrier for receiving information from a maximum of V downlink carriers, and at least one element in the value set of V is a positive integer greater than K; and / or, the second capability information is used to indicate K. In the above scheme, the first device generates the second capability information and sends the second capability information to the second device. The second capability information is used to indicate the ability of the first device to support downlink carriers, so that the second device determines the ability of the first device to support downlink carriers based on the received second capability information. The second device can configure the actual number of downlink carriers for the first device based on the ability of the first device to support downlink carriers.

[0011] In one possible implementation, the determining of N uplink carriers from the T uplink carriers includes: receiving third configuration information from the second device, the third configuration information being used to indicate the uplink carriers and / or the number of enabled uplink carriers enabled by the second device for the first device, and the number of uplink carriers enabled by the second device for the first device can be greater than L; and determining the N uplink carriers from the uplink carriers enabled by the second device for the first device. In the above scheme, the third configuration information is used to indicate the uplink carriers and / or the number of enabled uplink carriers enabled by the second device for the first device. For example, the third configuration information can directly indicate the uplink carriers and / or the number of enabled uplink carriers enabled by the second device for the first device, and the first device determines the number of uplink carriers enabled by the second device for the first device through the third configuration information.

[0012] In one possible implementation, the determining of W downlink carriers from the J downlink carriers includes: receiving fourth configuration information from the second device, the fourth configuration information being used to indicate the downlink carriers and / or the number of enabled downlink carriers enabled by the second device for the first device, and the number of downlink carriers enabled by the second device for the first device can be greater than K; and determining the W uplink carriers from the downlink carriers enabled by the second device for the first device. In the above scheme, the fourth configuration information is used to indicate the downlink carriers and / or the number of enabled downlink carriers enabled by the second device for the first device. For example, the fourth configuration information can directly indicate the downlink carriers and / or the number of enabled downlink carriers enabled by the second device for the first device. The first device determines the downlink carriers and / or the number of enabled downlink carriers enabled by the second device for the first device through the fourth configuration information.

[0013] In a possible implementation, T is greater than J, where J is the number of downlink carriers configured by the second device for the first device; and / or L is greater than K, where K is the maximum number of downlink carriers that the first device can simultaneously receive downlink signals.

[0014] In one possible implementation, the first capability information is used to enable the second device to determine that: the number of uplink carriers that the first device supports the second device to configure for the first device can be greater than L; and / or, the first capability information is used to enable the second device to determine that: the maximum number of uplink carriers that the first device can support the second device to configure for the first device is S; and / or, the first capability information is used to enable the second device to determine that: the maximum number of uplink carriers that the first device can simultaneously perform uplink transmission is L. In the above scheme, specifically, the first capability information is used to indicate that the first device can determine the uplink carrier for sending information from more than L uplink carriers, so that the second device determines, based on the received first capability information, that the number of uplink carriers that the first device supports the second device to configure for the first device can be greater than L, and the second device can configure uplink carriers for the first device based on the capability of the first device to support uplink carriers. Specifically, the first capability information is used to indicate that the first device is capable of supporting the determination of an uplink carrier for sending information from a maximum of S uplink carriers, thereby enabling the second device to determine, based on the received first capability information, that the maximum number of uplink carriers that the first device can support the second device to configure for the first device is S, and the second device can configure uplink carriers for the first device based on the first device's capability of supporting uplink carriers. Specifically, the first capability information is used to indicate L, thereby enabling the second device to determine, based on the received first capability information, that the maximum number of uplink carriers that the first device can simultaneously perform uplink transmissions is L, and the second device can configure an actual number of concurrent uplink carriers for the first device not exceeding L based on the first device's capability of supporting uplink carriers.

[0015] In one possible implementation, the second device is capable of configuring a maximum of M uplink carriers for the first device, where M is a positive integer greater than L. In the above scheme, the second device is capable of configuring a maximum of M uplink carriers for the first device, that is, the second device has the ability to configure a maximum number of uplink carriers of M for the first device, where M is greater than L. For example, the value of L is 2, and the value of M can be 5. Optionally, the first configuration information can be used to instruct the second device to configure a maximum of M uplink carriers for the first device, that is, the first configuration information can configure a maximum of M uplink carriers for the user equipment. The maximum number of uplink carriers that the first device can simultaneously transmit uplink is L. Wherein M is a positive integer greater than 1, and L is a positive integer less than M.

[0016] In one possible implementation, M is greater than Q, where Q is the maximum number of downlink carriers that the second device can configure for the first device. In the above solution, M is greater than Q, meaning that uplink and downlink carriers do not need to appear in pairs. This resolves limitations on spectrum resource utilization, and the maximum number of downlink concurrent carriers received by the user equipment is less than the maximum number of uplink concurrent carriers received by the user equipment. This does not increase the complexity of the user equipment, making it suitable for services primarily based on the above, and meeting the user equipment's need for more uplink carriers.

The words "first," "second," "A," and "B" do not limit the number or order of execution, and the words "first," "second," "A," and "B" do not necessarily mean different. In the embodiments of the present application, words such as "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described as "exemplary" or "for example" should not be construed as preferred or advantageous over other embodiments or design solutions. The use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner to facilitate understanding.

[0064] The terminal device involved in the embodiments of the present application can also be referred to as a terminal, which can be a device with wireless transceiver function, which can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; or can be deployed on the water surface (such as a ship, etc.); or can be deployed in the air (for example, on an airplane, a balloon, or a satellite, etc.). The terminal device can be a user equipment (UE), wherein the UE includes a handheld device, a vehicle-mounted device, a wearable device, or a computing device with wireless communication function. Exemplarily, the UE can be a mobile phone, a tablet computer, or a computer with wireless transceiver function. Or the terminal device can be a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal in industrial control, a wireless terminal in unmanned driving, a wireless terminal in telemedicine, a wireless terminal in a smart grid, a wireless terminal in a smart city, or a wireless terminal in a smart home, etc. In the embodiments of the present application, the device for realizing the function of the terminal device can be a terminal device, or it can be a device that can support the terminal device to realize the function, such as a chip system, which can be installed in the terminal device, or the device can be used in combination with the terminal device. In the embodiments of the present application, the chip system can be composed of chips, or it can include chips and other discrete devices. In the embodiments of the present application, the technical solution provided in the embodiments of the present application is specifically described by taking the terminal device as an example in which the device for realizing the function of the terminal device is a terminal device.

[0065] The terminal device in the mMTC scenario may be a reduced capability terminal device. Among them, the reduced capability terminal device can also be called a light terminal device. For example, the reduced capability (REDCAP) terminal device in the NR system has lower capability than the traditional terminal device. For example, the REDCAP terminal device has one or more of the following characteristics compared to the traditional terminal device: support for narrower bandwidth, fewer configured antennas, smaller maximum transmit power supported, lower duplex capability supported (for example, traditional terminal devices support full-duplex frequency division duplex, REDCAP terminal devices support half-duplex frequency division duplex), and weaker data processing capability (for example, REDCAP terminal devices can process less data than traditional terminal devices in the same time, or REDCAP terminal devices take longer to process the same data than traditional terminal devices). Therefore, REDCAP terminal devices and traditional terminal devices may require different system information, dedicated access networks, and / or control channels with different performance, etc. Among them, traditional terminal devices can be non-REDCAP terminal devices, which primarily support enhanced mobile broadband (eMBB) services and / or ultrareliable and low latency communications (URLLC) services. Compared to REDCAP terminal devices, traditional terminal devices can be regarded as high-capability terminal devices or terminal devices with unlimited capabilities. Optionally, traditional terminal devices can be replaced with terminal devices introduced in the future that have higher capabilities than REDCAP terminal devices.

[0066] The network equipment provided in the embodiment of the present application may include: a base station (BS), which may be a device deployed in a wireless access network that can communicate wirelessly with a terminal device. Among them, the base station may have various forms, such as a macro base station, a micro base station, a relay station, an access point such as a satellite, a drone, or an aircraft. Exemplarily, the base station involved in the embodiment of the present application may be a base station in a 5G mobile communication system and its evolution system, or a base station in LTE. Among them, the base station in the 5G mobile communication system may also be called a transmission reception point (TRP) or a gNB. In the embodiment of the present application, the device for implementing the function of the network device may be a network device, or it may be a device that can support the network device to implement the function, such as a chip system. The device can be installed in the network device, or the device can be used in combination with the network device. In the embodiment of the present application, the technical solution provided in the embodiment of the present application is specifically described by taking the device for implementing the function of the network device as an example of a network device.

[0067] The technical solutions provided in the embodiments of the present application can be applied to wireless communications between communication devices. Wireless communications between communication devices may include: wireless communications between network devices and terminal devices, wireless communications between network devices, or wireless communications between terminal devices. In the embodiments of the present application, the term "wireless communications" may also be simply referred to as "communication," and the term "communication" may also be described as "data transmission," "information transmission," or "transmission." This technical solution can be used for wireless communications between a scheduling entity and subordinate entities, where the scheduling entity can allocate resources to the subordinate entities. Those skilled in the art can apply the technical solutions provided in the embodiments of the present application to wireless communications between other scheduling entities and subordinate entities, such as wireless communications between macro base stations and micro base stations, or between first-type terminal devices and second-type terminal devices. The first-type terminal devices and the second-type terminal devices may represent two different types of terminal devices. For example, the first-type terminal device may be a terminal device used in an industrial wireless sensor network (IWSN), and the second-type terminal device may be a terminal device used in video surveillance. Alternatively, the first-type terminal device may be a type 1 reduced-capability terminal device, and the second-type terminal device may be a type 2 reduced-capability terminal device and a non-reduced-capability terminal device. For example, the first type of terminal device may be a terminal device for an industrial wireless sensor network, and the second type of terminal device may be a terminal device for video surveillance and an enhanced mobile broadband (eMBB) terminal device.

[0068] In a mobile communication system, the propagation distance (or coverage) of a signal is usually inversely proportional to the frequency of the communication band. That is, the higher the frequency band or frequency point used in the mobile communication system, the smaller its propagation distance (or coverage). For example, the propagation distance (or coverage) corresponding to a mobile communication system using a 3.5 gigahertz (GHz) frequency band is usually smaller than the propagation distance (or coverage) corresponding to a 1.8 GHz frequency band. Thanks to the use of multi-antenna transmission and multi-antenna reception technology in communication equipment, the propagation distance (or coverage) of the signal can be further improved. The carriers used in mobile communication systems can be divided into uplink (UL) carriers and downlink (DL) carriers. The coverage of the downlink carrier is usually better than that of the uplink carrier.

[0069] like Figure 1 The figure shows a schematic diagram of carriers used in communication between a base station and a user equipment according to an embodiment of the present application. For example, when the base station uses the 3.5 GHz frequency band for communication, the coverage of the downlink carrier is generally better than the coverage of the uplink carrier. In order to ensure the coverage performance of the user equipment, for example, when the coverage of the user equipment is poor, the uplink transmission of the user equipment can be changed from the 3.5 GHz frequency band to a low-frequency band (for example, 1.8 GHz or 2.1 GHz) to obtain better uplink carrier coverage.

[0070] In the current carrier aggregation mechanism, one primary cell (PCell) and multiple secondary cells (SCells) are used. Figure 2a Figure 2 shows a schematic diagram of the current uplink and downlink carrier pairs. In downlink carrier aggregation (DL CA) scenarios, using PCell, Scell-1, and Scell-2, uplink and downlink carriers typically appear in pairs. That is, the same number of downlink carriers must correspond to the same number of uplink carriers. This results in inflexible use of spectrum resources in carrier aggregation scenarios. Furthermore, because uplink and downlink carriers appear in pairs, user equipment must have parallel reception and / or transmission capabilities to support the aforementioned carrier aggregation, but this significantly increases user equipment complexity.

[0071] like Figure 2bThe figure shows a schematic diagram of the current unpaired uplink and downlink carriers. In a downlink carrier aggregation (DL CA) scenario, using PCell, Scell-1, and Scell-2, uplink and downlink carriers can also be unpaired. Typically, the number of downlink carriers exceeds the number of uplink carriers. For example, the uplink and downlink carriers of the PCell are paired, but Scell-1 and Scell-2 are configured only with downlink carriers, not uplink carriers. That is, the Scell ​​includes downlink carriers but not uplink carriers (not applicable, NA).

[0072] The current carrier aggregation mechanism has the problem of limited spectrum usage and cannot flexibly use spectrum resources. For example, uplink carriers and downlink carriers usually appear in pairs. If the user equipment supports carrier aggregation of up to P1 downlink carriers, each downlink carrier in the P1 downlink carriers has a corresponding uplink carrier component. That is, the P1 downlink carrier needs to have a corresponding P1 uplink carrier component. On the one hand, this will bring about great restrictions on the utilization of spectrum resources, and carrier aggregation can only be used when the spectrum is paired. On the other hand, the maximum number of carriers for downlink parallel reception of the user equipment is the same as the maximum number of carriers for uplink concurrent transmission of the user equipment, which will increase the complexity of the user equipment. Moreover, if the above-mentioned services are mainly carried out, the UE needs more uplink carriers, but at this time it has to be associated with many downlink carriers, which increases the channel state information (CSI) measurement of the downlink associated carriers.

[0073] An embodiment of the present application proposes an information transmission method, which is applicable to communication scenarios between network equipment and various types of terminal equipment, and can configure uplink carriers and / or downlink carriers for different types of terminal equipment. In an embodiment of the present application, an uplink carrier does not mean that only uplink transmission can be performed on the carrier. If there is also downlink reception on a carrier, but the resources of the carrier are mainly used for uplink transmission, the carrier can also be called an uplink carrier. Of course, a carrier on which only uplink transmission can be performed is also called an uplink carrier. For example, in an embodiment of the present application, all resources of at least one of the uplink carriers can only be used for uplink transmission, and / or part of the resources of at least one of the uplink carriers can be used for downlink reception.

[0074] In the embodiments of the present application, a downlink carrier does not mean that only downlink reception is possible on that carrier. If a carrier also has uplink transmission, but its resources are primarily used for downlink reception, that carrier can also be referred to as a downlink carrier. Of course, a carrier that is only capable of downlink reception is also a downlink carrier. For example, in the embodiments of the present application, all resources of at least one downlink carrier can be used only for downlink reception, and / or some resources of at least one downlink carrier can be used for uplink transmission.

[0075] In an embodiment of the present application, the user equipment can determine at least one carrier for uplink transmission and / or determine at least one carrier for downlink reception based on the configuration of the network equipment and / or preset rules (such as one or more of channel conditions, user equipment type / capability, service type / requirements, load parameters, synchronization raster, antenna configuration, RF channel, power amplifier, antenna port, etc.).

[0076] For example, the UE performs uplink transmission on the carriers included in the first set. The first set includes at least a first carrier and a second carrier, and the first carrier is in the uplink operation band of the Ni band. The second carrier is in the uplink operation band of the Nj band, and the (FUL, low) of the Nj band is not lower than the (FUL, high) of the Ni band. Or the center frequency of the second carrier is higher than the center frequency of the first carrier. The second carrier is a carrier for full uplink transmission, or the ratio of the uplink time slot to the downlink time slot of the second carrier is X:Y, where X can be greater than or equal to Y, or the second carrier is a component carrier for time division duplexing. The UE receives downlink information on the carriers included in the second set, and the second set includes at least a third carrier. The third carrier is in the downlink operation band of the Ni band, and the (FDL, low) of the Ni band is not lower than the (FUL, high) of the Ni band. Or the (FDL, low) of the Ni band is lower than the (FUL, low) of the Nj band. Or the center frequency of the third carrier is higher than the center frequency of the first carrier, and the center frequency of the third carrier is lower than the center frequency of the second carrier. Wherein, the above-mentioned Ni or Nj is the frequency band number. (FUL, low) is the low frequency point of the uplink frequency corresponding to the frequency band, and (FUL, high) is the high frequency point of the uplink frequency corresponding to the frequency band.

[0077] The UE determines at least one carrier for uplink transmission and / or at least one carrier for downlink reception based on the configuration of the network device and / or preset rules (such as one or more of channel conditions, UE type / capability, service type / requirement, login parameters, synchronization grid, antenna configuration, RF channel, power amplifier, antenna port, etc.). The UE performs uplink transmission on the carriers included in the first set, wherein the first set includes at least a first carrier and a second carrier. The first carrier is in the uplink operating band of the Ni band. The second carrier is in the uplink operating band of the Nj band, and the (FUL, low) of the Nj band is or is not lower than the (FUL, high) of the Ni band. Or the center frequency of the second carrier is higher than the center frequency of the first carrier. The second carrier is a carrier for full uplink transmission, or the ratio of the uplink time slot to the downlink time slot of the second carrier is X:Y, where X can be greater than or equal to Y, or the second carrier is a component carrier for time division duplexing. The UE performs uplink transmission to the first node via the first carrier. The UE performs uplink transmission to the second node via the second carrier. Wherein, the first node and the second node are different communication nodes.

[0078] For example, in an embodiment of the present application, all frequency resources of each uplink carrier in one or more uplink carriers can only be used for uplink transmission. For another example, in an embodiment of the present application, some resources of at least one uplink carrier can be used for downlink reception. For another example, in an embodiment of the present application, all frequency resources of some uplink carriers can only be used for uplink transmission, while some uplink carriers have some resources that can be used for downlink reception.

[0079] See also Figure 3 As shown, it is a schematic diagram of an interaction process between the first device and the second device provided in an embodiment of the present application. In this interaction process, steps 301 to 303 are described from the side of the second device, and steps 311 to 313 are described from the side of the first device. Figure 3 The interaction process shown mainly includes the following steps:

[0080] 301. A second device sends first configuration information to a first device, where the first configuration information is used to instruct the second device to configure T uplink carriers for the first device. At least one element in a value set of T is a positive integer greater than L, where L is the maximum number of uplink carriers that the first device can simultaneously perform uplink transmissions on.

[0081] For example, all uplink carriers within the T uplink carriers configured by the second device for the first device can be used for uplink carrier selection (or uplink carrier switching, or adjustment of the uplink transmission channel, or switching or adjustment of the uplink transmission antenna, or measurement of the uplink carrier). For another example, only some of the uplink carriers within the T uplink carriers configured by the second device for the first device can be used for uplink carrier selection (or uplink carrier switching, or adjustment of the uplink transmission channel, or switching or adjustment of the uplink transmission antenna, or measurement of the uplink carrier). For example, among the T uplink carriers configured by the second device for the first device, except for those used for uplink carrier selection (or uplink carrier switching, or adjustment of the uplink transmission channel, or switching or adjustment of the uplink transmission antenna, or measurement of the uplink carrier), the other one or more uplink carriers can be used for wireless resource management measurement or can be used for other measurements. That is, one or more carriers within the T uplink carriers configured by the second device for the first device that are not used for uplink carrier selection (or uplink carrier switching, or adjustment of the uplink transmission channel, or switching or adjustment of the uplink transmission antenna) can be used for wireless resource management measurements, or can be used for other measurements.

[0082] In the application embodiment, the first device may be a terminal device, and the second device may be a network device. Alternatively, the first device may be a terminal device, and the second device may be a counterpart device of the terminal device. The second device may configure an uplink carrier for the first device, and the second device may configure multiple uplink carriers for the first device. For example, the number of uplink carriers that the second device can configure for the first device is represented by T. The maximum number of uplink carriers that the first device can simultaneously perform uplink transmission is represented by L, and the value set of T may include one or more elements, and at least one element in the value set of T is greater than L, for example, T may be greater than L, or T may be less than or equal to L. Specifically, the maximum number of uplink carriers that the first device can simultaneously perform uplink transmission refers to the maximum uplink concurrency capability of the first device, and the value of L represents the size of the uplink concurrency capability of the first device. For example, the minimum value of L is 2. Among them, T represents the actual number of uplink carriers configured by the second device for the first device. At least one element in the value set of T can be greater than L, that is, the second device can configure for the first device a number that exceeds the maximum number of uplink carriers that can be transmitted simultaneously by the first device. In other words, the actual number of uplink carriers configured by the second device for the first device exceeds the maximum uplink concurrency capability of the first device. For example, if the value of L is 3, the maximum uplink concurrency capability of the first device is 3 uplink carriers, and the value of T can be greater than the value of L. For example, if the value of T is 5, the actual number of uplink carriers configured by the second device for the first device is 5, and 5 is greater than 3, indicating that the actual number of uplink carriers configured by the second device for the first device exceeds the maximum uplink concurrency capability of the first device. It is not limited to that the value of T can also be less than or equal to the value of L. For example, if the value of T is 3 and the value of L is 3, it means that the actual number of uplink carriers configured by the second device for the first device is equal to the maximum uplink concurrency capability of the first device.

[0083] It should be noted that, in the embodiment of the present application, at least one element in the value set of T indicated by the first configuration information can be greater than L, which means that the first configuration information has the function of configuring the actual number of uplink carriers for the first device to exceed the maximum number of uplink concurrent carriers of the first device. Of course, it is not limited to that the actual number of uplink carriers configured by the second device for the first device can exceed the maximum uplink concurrent capability of the first device, or the actual number of uplink carriers configured by the second device for the first device can not exceed the maximum uplink concurrent capability of the first device, or the actual number of uplink carriers configured by the second device for the first device always exceeds or is not less than the maximum uplink concurrent capability of the first device. In the embodiment of the present application, the second device has the function of configuring the actual number of uplink carriers for the first device to exceed the maximum uplink concurrent capability of the first device, but it does not necessarily mean that "the second device has the actual number of uplink carriers configured for the first device to exceed the maximum uplink concurrent capability of the first device". It is necessary to determine the actual number of uplink carriers configured by the second device for the first device according to the application scenario. Similarly, at least one element in the value set of T indicated by the first configuration information can be greater than L, but it does not necessarily mean that "T indicated by the first configuration information must be greater than L". T indicated by the first configuration information can also be less than or equal to L, which is not limited here.

[0084] In some embodiments of the present application, the second device may configure at least T uplink carriers for the first device, that is, the second device may configure T uplink carriers for the first device, or the second device may configure T+1 uplink carriers for the first device, or the second device may configure T+2 uplink carriers for the first device. In the embodiments of the present application, the actual number of uplink carriers configured by the second device for the first device is not limited. In particular, T=3, or T=L.

[0085] In some embodiments of the present application, in addition to performing the aforementioned step 301, the information transmission method provided in the embodiments of the present application further includes:

[0086] The second device receives the first capability information from the first device;

[0087] The second device determines, based on the first capability information, that the first device is capable of determining an uplink carrier for sending information from more than L uplink carriers; and / or,

[0088] The second device determines, based on the first capability information, that the first device can support determining an uplink carrier for sending information from a maximum of S uplink carriers, where at least one element in a value set of S is a positive integer greater than L; and / or,

[0089] The second device determines L according to the first capability information; and / or,

[0090] The second device determines, based on the first capability information, that the first device can support determining an uplink carrier for sending information from a maximum of A enabled uplink carriers. For example, A is a positive integer greater than L.

[0091] The first device generates first capability information and sends the first capability information to the second device. The first capability information indicates the first device's ability to support uplink carriers, so that the second device determines the first device's ability to support uplink carriers based on the received first capability information. The second device can configure the actual number of uplink carriers for the first device based on the first device's ability to support uplink carriers.

[0092] Specifically, the first capability information may indicate the capability of the first device to transmit multiple uplink carriers. For example, the first capability information is used to indicate that the first device is capable of determining an uplink carrier for transmitting information from more than L uplink carriers. It should be noted that the uplink carrier determined here for transmitting information refers to a potential or candidate uplink carrier that can be used for uplink transmission, or a (candidate) carrier for carrier selection (or channel switching), or an enabled uplink carrier. That is, the uplink carrier determined for transmitting information is not an uplink carrier that the first device can actually transmit uplink. The first device may determine an uplink carrier that can actually transmit uplink (such as in parallel) from the candidate uplink carriers. That is, determining an uplink carrier for transmitting information refers to determining which uplink carriers may be used for actual uplink transmission. The number of candidate uplink carriers may exceed the number of uplink carriers that the first device can actually transmit uplink in parallel. Alternatively, the number of candidate uplink carriers may exceed the maximum number of uplink carriers that the first device can actually transmit uplink in parallel.

[0093] The first capability information reflects that the first device has the ability to determine an uplink carrier for transmitting information from more than L uplink carriers. That is, through the first capability information, the second device can determine that the first device can determine an uplink carrier for transmitting information from more than L uplink carriers. Reflection means that the first capability information can indicate directly, indirectly, explicitly, implicitly, or otherwise. Furthermore, the first capability information indicates that the first device can determine an uplink carrier for transmitting information from more than L uplink carriers. This indication can be direct, indirect, explicit, or implicit. The first capability information reflects that "the first device can determine an uplink carrier for transmitting information from more than L uplink carriers." "The first device can determine an uplink carrier for transmitting information from more than L uplink carriers" is the result of the first capability information reflecting the above. The first capability information can indicate this result directly or indirectly, without limitation. The description of "reflection" in subsequent embodiments is referred to here, and "reflection" will not be described in detail.

[0094] Specifically, the first capability information is used to indicate that the first device is capable of supporting determination of an uplink carrier for sending information from a maximum of S uplink carriers. The first capability information reflects that the first device has the capability of supporting determination of an uplink carrier for sending information from a maximum of S uplink carriers. That is, based on the first capability information, the second device can determine that the first device is capable of supporting determination of an uplink carrier for sending information from a maximum of S uplink carriers, where at least one element in the value set of S is a positive integer greater than L.

[0095] Specifically, the first capability information is used to indicate L, that is, the first capability information can directly indicate the "maximum number of uplink carriers that the first device can simultaneously perform uplink transmission", and the "maximum number of uplink carriers that the first device can simultaneously perform uplink transmission" is equal to L. In addition, the first capability information is used to indicate L, which can also be expressed as the first capability information reflecting L. For a detailed description of indication and reflection, see the above content.

[0096] For example, the maximum number of uplink component carriers that a user equipment can simultaneously transmit uplink is L. The user equipment sends first capability information to a peer device, where the first capability information is used to indicate: the maximum number L of uplink carriers that the user equipment can simultaneously transmit information; and that the user equipment supports the peer device configuring a number of uplink carriers greater than L for the user equipment. In this embodiment of the present application, the peer device determines the user equipment's capability of supporting uplink carriers based on the received first capability information, and the peer device may configure the actual number of uplink carriers for the user equipment based on the user equipment's capability of supporting uplink carriers.

[0097] Specifically, the first capability information is used to indicate that the first device can support determining an uplink carrier for sending information from a maximum of A enabled uplink carriers. For example, A is a positive integer greater than L. Here, enabling means that the second device activates the uplink carrier, or the second device configures the uplink carrier so that the carrier can be used by the first device. For another example, enabling a carrier means indicating that the radio frequency channel of the terminal device is ready for use of the carrier, so the switching time between enabled carriers is short. Through the first capability information, the second device can determine that the first device can support a maximum of A enabled uplink carriers, and the second device can determine the uplink carrier available to the first device from a maximum of A enabled uplink carriers.

[0098] In some embodiments of the present application, the second device can configure a maximum of M uplink carriers for the first device, where M is a positive integer greater than L.

[0099] The second device is capable of configuring a maximum of M uplink carriers for the first device, i.e., the second device has the capability of configuring a maximum number of M uplink carriers for the first device, where M is greater than L. For example, the value of L is 2, and the value of M can be 5. Optionally, the first configuration information can be used to instruct the second device to configure a maximum of M uplink carriers for the first device, i.e., the first configuration information can configure a maximum of M uplink carriers for the user equipment. The maximum number of uplink carriers capable of simultaneous uplink transmission by the first device is L, where M is a positive integer greater than 1, and L is a positive integer less than M.

[0100] In some embodiments of the present application, in addition to performing the aforementioned step 301, the information transmission method provided in the embodiments of the present application further includes:

[0101] The second device sends third configuration information to the first device, where the third configuration information is used to indicate the uplink carriers and / or the number of uplink carriers enabled by the second device for the first device. The number of uplink carriers enabled by the second device for the first device can be greater than L.

[0102] The enabling in the embodiment of the present application may be activation, configuration, or indication.

[0103] In addition to sending the first configuration information to the first device, the second device may also send third configuration information to the first device. The first configuration information and the third configuration information may be sent to the first device simultaneously. For example, the second device may carry the first configuration information and the third configuration information in the same signaling, information element, or field. Alternatively, the first configuration information and the third configuration information may be sent to the first device separately in different signaling, information elements, or fields, which is not limited here.

[0104] In an embodiment of the present application, the third configuration information is used to indicate the uplink carriers and / or the number of enabled uplink carriers that the second device enables for the first device. For example, the third configuration information can directly indicate the uplink carriers and / or the number of enabled uplink carriers that the second device enables for the first device, and the first device determines the number of uplink carriers that the second device enables for the first device through the third configuration information. For another example, the third configuration information can directly indicate the number of disabled uplink carriers and / or the number of disabled uplink carriers, and the first device determines the number of disabled uplink carriers through the third configuration information, and then determines the number of enabled uplink carriers based on the total number of uplink carriers and the number of disabled uplink carriers. Among them, the number of uplink carriers enabled by the second device for the first device can be greater than L, and there is no limitation on the specific value of the number of uplink carriers enabled by the second device for the first device.

[0105] 311. A first device receives first configuration information from a second device, where the first configuration information is used to instruct the second device to configure T uplink carriers for the first device, where at least one element in the value set of T is a positive integer greater than L, and L is the maximum number of uplink carriers that the first device can simultaneously perform uplink transmission.

[0106] In an embodiment of the present application, the first device can receive first configuration information, and the first device determines through the first configuration information that the second device has configured T uplink carriers for the first device. For an explanation of the first configuration information and the value of T, please refer to the description in step 301 and will not be repeated here.

[0107] In some embodiments of the present application, in addition to performing the aforementioned step 311, the information transmission method provided in the embodiments of the present application further includes:

[0108] The first device reports the first capability information to the second device;

[0109] The first capability information is used to indicate that the first device can determine an uplink carrier for sending information from more than L uplink carriers; and / or,

[0110] The first capability information is used to indicate that the first device can support determining an uplink carrier for sending information from a maximum of S uplink carriers, where S is a positive integer greater than L; and / or,

[0111] The first capability information is used to indicate L; and / or,

[0112] The first capability information is used to indicate that the first device can support determining an uplink carrier for sending information from a maximum of A enabled uplink carriers, where A is a positive integer greater than L.

[0113] The first device generates first capability information and sends the first capability information to the second device. The first capability information is used to indicate the capability of the first device to support uplink carriers, so that the second device can determine the capability of the first device to support uplink carriers based on the received first capability information. The second device can configure the actual number of uplink carriers for the first device based on the capability of the first device to support uplink carriers.

[0114] Specifically, the first capability information may indicate the capability of the first device to use multiple uplink carriers. For example, the first capability information is used to indicate that the first device is capable of determining an uplink carrier for sending information from more than L uplink carriers, wherein the first capability information reflects that the first device has the capability of determining an uplink carrier for sending information from more than L uplink carriers, that is, through the first capability information, the second device can determine that the first device is capable of determining an uplink carrier for sending information from more than L uplink carriers. Reflection means that the first capability information may indicate directly, or the first capability information may indicate indirectly, or explicitly, or implicitly, etc. In addition, the first capability information indicates that the first device is capable of determining an uplink carrier for sending information from more than L uplink carriers. The indication here may refer to a direct indication, or an indirect indication, or an explicit indication, or an implicit indication, etc. The first capability information reflects that "the first device is capable of determining an uplink carrier for transmitting information from more than L uplink carriers." This "capability of the first device to determine an uplink carrier for transmitting information from more than L uplink carriers" is the result reflected by the first capability information. The first capability information may indicate the result directly or indirectly, and this is not limited here. For the description of "reflection" in subsequent embodiments, please refer to this article, and "reflection" will not be described in detail below.

[0115] In the embodiment of the present application, determining an uplink carrier for sending information refers to the first device determining potential or candidate uplink carriers that can be used for uplink transmission, and does not refer to the uplink carriers that the first device can actually transmit uplink in parallel. The first device can determine the uplink carriers that can actually transmit uplink in parallel from the candidate uplink carriers. That is, determining the uplink carrier for sending information refers to determining which uplink carriers may be used for actual uplink transmission. Alternatively, the number of candidate uplink carriers may exceed the maximum number of uplink carriers that the first device can actually transmit uplink in parallel.

[0116] Specifically, the first capability information is used to indicate that the first device is capable of supporting the determination of an uplink carrier for sending information among a maximum of S uplink carriers, wherein the first capability information reflects that the first device has the ability to support the determination of an uplink carrier for sending information among a maximum of S uplink carriers, that is, through the first capability information, the second device can determine that the first device is capable of supporting the determination of an uplink carrier for sending information among a maximum of S uplink carriers, and at least one element in the value set of S is a positive integer greater than L.

[0117] Specifically, the first capability information is used to indicate L. That is, the first capability information can directly indicate the "maximum number of uplink carriers that the first device can simultaneously perform uplink transmissions." The "maximum number of uplink carriers that the first device can simultaneously perform uplink transmissions" is equal to L. Alternatively, the first capability information being used to indicate L can also be expressed as "the first capability information reflects L." Examples of indication and reflection are described in detail above and are not repeated here.

[0118] Specifically, the first capability information is used to indicate that the first device can support determining an uplink carrier for sending information from a maximum of A enabled uplink carriers. For example, A is a positive integer greater than L. Here, enabling means that the second device activates the uplink carrier, or the second device configures the uplink carrier so that the carrier can be used by the first device. Through the first capability information, the second device can determine that the first device can support a maximum of A enabled uplink carriers, and the second device can determine the uplink carrier available to the first device from the maximum A enabled uplink carriers.

[0119] In some embodiments of the present application, the first capability information is used to enable the second device to determine that: the first device supports the number of uplink carriers configured by the second device for the first device to be greater than L; and / or,

[0120] The first capability information is used to enable the second device to determine that the maximum number of uplink carriers that the first device can support, configured by the second device for the first device, is S; and / or,

[0121] The first capability information is used to enable the second device to determine that the maximum number of uplink carriers that the first device can simultaneously perform uplink transmission is L;

[0122] and / or,

[0123] The first capability information is used to enable the second device to determine that the first device can support determining an uplink carrier for sending information from a maximum of A enabled uplink carriers, where A is greater than L.

[0124] Specifically, the first capability information is used to indicate that the first device is capable of determining an uplink carrier for sending information from more than L uplink carriers, so that the second device determines, based on the received first capability information, that the first device supports a number of uplink carriers configured by the second device for the first device that is greater than L. The second device can configure the actual number of uplink carriers for the first device based on the capability of the first device to support uplink carriers.

[0125] Specifically, the first capability information is used to indicate that the first device can support determining an uplink carrier for sending information from a maximum of S uplink carriers, so that the second device determines, based on the received first capability information, that the first device can support the maximum number of uplink carriers configured by the second device to the first device as S. The second device can configure the actual number of uplink carriers for the first device based on the capability of the first device to support uplink carriers.

[0126] Specifically, the first capability information is used to indicate L, so that the second device determines that the maximum number of uplink carriers that the first device can simultaneously perform uplink transmission is L based on the received first capability information. The second device can configure the actual number of uplink carriers for the first device based on the capability of the first device to support uplink carriers.

[0127] For example, the first device is a user equipment (UE), and the second device is a peer device of the UE. For example, the peer device may be a base station, a machine type communication terminal, or a communication terminal for a connected vehicle service. For example, L is a positive integer greater than 1. For example, L = 2.

[0128] 302. The second device determines N uplink carriers from T uplink carriers, where N is a positive integer less than or equal to L.

[0129] Among them, N uplink carriers are used to receive information from the first device. For example, the first device can transmit uplink information with the second device in N uplink carriers, and the N uplink carriers are used for the second device to receive information from the first device. For another example, the first device can transmit uplink information with the third device in N uplink carriers, and the N uplink carriers are used for the third device to receive information from the first device. For another example, the first device can transmit uplink information with the second device and the third device in N uplink carriers, and the N uplink carriers are used for the second device and the third device to receive information from the first device. Specifically, the second device can be a macro station, and the third device can be a micro station. In the subsequent embodiments, taking the example of the first device sending information to the second device in N uplink carriers, the second device can also perform the subsequent step 303.

[0130] For example, the first device sends an uplink signal on an uplink carrier so that the second device performs measurements on some or all of the T uplink carriers, so that the second device determines N uplink carriers from the T uplink carriers. The second device can configure an uplink carrier set for uplink carrier selection (or uplink carrier switching, or adjustment of the uplink transmission channel, or switching or adjustment of the uplink transmission antenna) for the first device. The uplink carrier set can include some of the T uplink carriers. For example, the time taken to switch between two different carriers in the uplink carrier set is relatively short. However, the switching time between at least two other different carriers in the T uplink carriers other than the carriers included in the uplink carrier set is relatively long.

[0131] In an embodiment of the present application, after the second device configures T uplink carriers for the first device, the second device may also determine the uplink carriers that the first device can actually use. For example, the second device performs carrier selection and determines the uplink carriers that the first device can actually use. Alternatively, the second device notifies the first device of the uplink carriers that the first device can actually use. In another example, the second device receives a notification or information sent by the first device and determines the uplink carriers that the first device can actually use based on the notification or information sent. The second device configures T uplink carriers for the first device, and the first device determines N uplink carriers from the T uplink carriers. These N uplink carriers are the uplink carriers that the first device can actually use. Since N is the number of carriers selected from the T uplink carriers, N is less than or equal to T. The maximum number of uplink carriers that the first device can simultaneously perform uplink transmission is represented by L, so N is less than or equal to L. For example, if the value of L is 3, the value of N can be less than 3 or equal to 3. The embodiment of the present application does not limit the value of N.

[0132] In some embodiments of the present application, the first device determines N uplink carriers from T uplink carriers, including: determining N uplink carriers that can be used for simultaneous uplink transmission from the uplink carriers configured by the second device for the first device, where N is a positive integer less than or equal to L. The N uplink carriers are the actual number of uplink carriers that the first device can use for simultaneous uplink transmission. N is the N uplink carriers determined by the first device from the uplink carriers configured by the second device for the first device. The value of N does not exceed the actual number of uplink carriers configured by the second device for the first device, nor does it exceed the uplink concurrency capability of the first device. It should be noted that step 302 may be an optional step in the implementation method of the second device.

[0133] 312. The first device determines N uplink carriers from T uplink carriers, where N is a positive integer less than or equal to L.

[0134] The first device selects an uplink carrier (or switches the uplink carrier, or adjusts the uplink transmission channel, or switches or adjusts the uplink transmission antenna) based on the downlink measurement. Or the first device sends an uplink signal on the uplink carrier so that the second device performs measurement on some or all of the T uplink carriers, so that the first device selects the uplink carrier (or switches the uplink carrier, or adjusts the uplink transmission channel, or switches or adjusts the uplink transmission antenna) according to the instruction of the second device. Or the first device sends an uplink signal on the uplink carrier so that the third device performs measurement on some or all of the T uplink carriers, so that the second device instructs the first device based on the measurement information reported by the third device to select the uplink carrier (or switches the uplink carrier, or adjusts the uplink transmission channel, or switches or adjusts the uplink transmission antenna). For example, the third device is a microcell, such as Pico, and the second device is Macro, that is, a macro base station. For another example, the first device receives a notification from the second device and determines N uplink carriers based on the notification.

[0135] In an embodiment of the present application, after the first device determines, through first configuration information, that the second device has configured T uplink carriers for the first device, the first device may also determine the uplink carriers that the first device can actually use. For example, the first device performs carrier selection and determines the uplink carriers that the first device can actually use. Optionally, the first device notifies the second device of the uplink carriers that the first device can actually use. In another example, the first device receives the notification from the second device and, based on the notification, determines the uplink carriers that the first device can actually use. The second device configures T uplink carriers for the first device, and the first device determines N uplink carriers from the T uplink carriers. These N uplink carriers are the uplink carriers that the first device actually uses. The value of N can be equal to 1, or greater than 1, such as 2. Since N is the number of carriers selected from the T uplink carriers, and is less than T, the maximum number of uplink carriers that the first device can simultaneously perform uplink transmissions is represented by L, and therefore N is less than or equal to L. For example, if the value of L is 3, the value of N can be less than 3, or equal to 3. The embodiment of the present application does not limit the value of N.

[0136] An example is given below: the second device configures T uplink carriers for the first device, where T = 5, L is the maximum number of uplink carriers that the first device can simultaneously perform uplink transmission, L = 3, and the first device determines N uplink carriers from the T uplink carriers, where N = 2. Therefore, the first device can determine two uplink carriers from the five uplink carriers, and the two uplink carriers are the uplink carriers used by the first device when performing uplink transmission. In the embodiment of the present application, the first terminal device has the ability to flexibly select carriers in more carriers than its uplink concurrency capability, so the first device can achieve flexible use of spectrum resources.

[0137] In some embodiments of the present application, step 312 in which the first device determines N uplink carriers from T uplink carriers may further include:

[0138] The first device receives third configuration information from the second device, where the third configuration information indicates the uplink carriers and / or the number of uplink carriers enabled by the second device for the first device. The number of uplink carriers enabled by the second device for the first device can be greater than L.

[0139] Optionally, the first device determines N uplink carriers from the uplink carriers enabled by the second device for the first device.

[0140] For example, among the T uplink carriers configured by the second device for the first device, switching between some carriers (or selection of uplink carriers, adjustment of uplink transmission channels, or switching or adjustment of uplink transmission antennas) requires a shorter time, while switching between some carriers (or selection of uplink carriers, adjustment of uplink transmission channels, or switching or adjustment of uplink transmission antennas) requires a longer time. The second device configures or indicates enabled uplink carriers for the first device from among the T uplink carriers, and the first device requires a shorter time to switch between carriers (or selection of uplink carriers, adjustment of uplink transmission channels, or switching or adjustment of uplink transmission antennas) among these enabled uplink carriers. The first device does not perform uplink carrier switching (or uplink carrier selection, or uplink transmission channel adjustment, or uplink transmission antenna switching or adjustment) on the non-enabled uplink carrier among the T uplink carriers, or the first device requires a long time to perform carrier switching (or uplink carrier selection, or uplink transmission channel adjustment, or uplink transmission antenna switching or adjustment) on the non-enabled uplink carrier among the T uplink carriers, or the first device (or the second device) performs wireless resource management measurements on at least one non-enabled uplink carrier among the T uplink carriers.

[0141] The second device may configure an enabled uplink carrier for the first device. For example, the first device sends an uplink signal on the uplink carrier so that the second device performs measurements on some or all of the T uplink carriers, so that the second device determines N uplink carriers from the T uplink carriers. The second device may configure an uplink carrier set for uplink carrier selection (or uplink carrier switching, or adjustment of the uplink transmission channel, or switching or adjustment of the uplink transmission antenna) for the first device. The uplink carrier set may include some of the T uplink carriers. For example, the time taken to switch between two different carriers in the uplink carrier set is relatively short. However, the switching time between at least two other different carriers in the T uplink carriers other than the carriers included in the uplink carrier set is relatively long.

[0142] In addition to receiving the first configuration information sent by the second device, the first device may also receive the third configuration information sent by the second device. The first device may receive the first configuration information and the third configuration information simultaneously. For example, the second device carries the first configuration information and the third configuration information through a single signaling message, information element, or field. The first device receives the first configuration information and the third configuration information through the same signaling message, information element, or field. Alternatively, the first device may receive the first configuration information and the third configuration information separately, which is not limited here.

[0143] In an embodiment of the present application, the third configuration information is used to indicate the uplink carriers enabled by the second device for the first device and / or the number of enabled uplink carriers. For example, the third configuration information can directly indicate the uplink carriers enabled by the second device for the first device. The first device determines the uplink carriers enabled by the second device for the first device through the third configuration information. For another example, the third configuration information can directly indicate the disabled uplink carriers. The first device determines the disabled uplink carriers through the third configuration information, and then determines the enabled uplink carriers based on the total uplink carriers and the disabled uplink carriers. Among them, the number of uplink carriers enabled by the second device for the first device can be greater than L. There is no limitation on the specific value of the number of uplink carriers enabled by the second device for the first device.

[0144] After the first device determines that the second device is an uplink carrier enabled by the first device, it can determine N uplink carriers from the uplink carriers enabled by the second device for the first device, where the N uplink carriers are uplink carriers actually used or transmitted in parallel by the first device. These N uplink carriers can be a portion of the uplink carriers enabled by the second device for the first device or all of the enabled carriers, which is not limited here.

[0145] The first device determines the N uplink carriers. This may be the first device determining the N uplink carriers based on its own measurements, or the first device determining the N uplink carriers based on one or more indication information (or configuration information, or downlink control information) received from the second device and sent to the first device.

[0146] An example is given below: the second device configures T uplink carriers for the first device, where T = 5, L is the maximum number of uplink carriers that the first device can simultaneously perform uplink transmission, L = 3, and the third configuration information indicates that the second device enables 4 uplink carriers for the first device, then the first device determines N uplink carriers from the 4 enabled uplink carriers, N = 2. Therefore, the first device can determine 2 uplink carriers from the 4 enabled uplink carriers, and the 2 uplink carriers are the uplink carriers used by the first device for uplink transmission. In the embodiment of the present application, the first terminal device has the ability to flexibly select carriers in more carriers than its uplink concurrency capability, so the first device can achieve flexible use of spectrum resources.

[0147] 313. The first device sends information in N uplink carriers.

[0148] In an embodiment of the present application, for example, the first device determines that N uplink carriers are the uplink carriers used by the first device for uplink transmission. The first device can transmit uplink information with the second device in the N uplink carriers, or the first device can transmit uplink information with the third device in the N uplink carriers, or the first device can transmit uplink information with the second device and the third device in the N uplink carriers. For example, the second device can be a macro station and the third device can be a micro station. Taking the example of the first device sending information to the second device in N uplink carriers, the first device sends information to the second device in N uplink carriers, thereby realizing communication between the first device and the second device. For example, if the value of N is 1, the first device can send information to the second device in 1 uplink carrier. For example, if the value of N is greater than 1, the first device can send information to the second device simultaneously in N uplink carriers. Or the first device can send information to the second device in time-division in N uplink carriers.

[0149] Optionally, 303 , the second device receives information from the first device in N uplink carriers.

[0150] In this embodiment of the present application, the second device determines N uplink carriers, which are used by the first device for simultaneous uplink transmission. The second device can transmit uplink information with the first device on the N uplink carriers. For example, the second device receives information from the first device on the N uplink carriers, thereby enabling communication between the second device and the first device.

[0151] As can be seen from the examples in the preceding embodiments, a first device first receives first configuration information from a second device. The second device, through the first configuration information, may instruct the first device to configure T uplink carriers, where at least one element in the set of values ​​for T is a positive integer greater than L. For example, the value of T may be greater than the value of L. L represents the maximum number of uplink carriers that the first device can simultaneously transmit uplinks. L may represent the maximum number of uplink carriers that the first device can use for simultaneous uplink transmissions, i.e., the first device can use a maximum of L uplink carriers for simultaneous uplink transmissions. After the first device determines that the second device has configured T uplink carriers for the first device, the first device determines N uplink carriers from the T uplink carriers. i.e., the first device may select a carrier from the T uplink carriers, where T may be greater than L. Therefore, the first device may select a carrier from a greater number of carriers than the maximum number of uplink carriers for simultaneous transmissions by the first device. Finally, the first device transmits information to the second device from the N uplink carriers, where the value of N is less than or equal to the value of L, thereby enabling information transmission between the first and second devices. In the embodiment of the present application, the first device has the ability to flexibly select carriers among more carriers that exceed its uplink concurrency capability, so that the second device can configure more uplink carriers for the first device, and the first device can flexibly select carriers among more carriers. Therefore, the first device can achieve flexible use of spectrum resources, effectively utilize appropriate resources for uplink transmission, improve uplink rate and coverage, and save power consumption of the first terminal device.

[0152] The aforementioned steps 301 to 303 and steps 311 to 313 describe the process of configuring the uplink carrier and transmitting uplink information. Next, the process of configuring the downlink carrier and transmitting downlink information is described. Terms and examples that are identical to those used in the configuration of the uplink carrier are not further described; please refer to the description of the preceding embodiment for details.

[0153] In the embodiment of the present application, the above content describes the process of uplink transmission, and the following example describes the process of downlink reception. For the meaning of downlink reception, please refer to the above content for details. Figure 4 As shown, the interaction process between the second device and the first device includes the following steps:

[0154] 401. The second device sends second configuration information to the first device, where the second configuration information is used to instruct the second device to configure J downlink carriers for the first device, where at least one element in the value set of J is a positive integer greater than K, and K is the maximum number of downlink carriers that the first device can simultaneously receive downlink signals.

[0155] 411. The first device receives second configuration information from the second device, where the second configuration information is used to instruct the second device to configure J downlink carriers for the first device, where at least one element in the value set of J is a positive integer greater than K, and K is the maximum number of downlink carriers that the first device can simultaneously receive downlink signals.

[0156] The second device can configure downlink carriers for the first device, and the second device can configure multiple downlink carriers for the first device. For example, the number of downlink carriers that the second device can configure for the first device is represented by J. If the maximum number of downlink carriers that the first device can simultaneously receive downlink signals is represented by K, then at least one element in the set of values ​​for J is greater than K. For example, J can be greater than K, or J can be less than or equal to K. For example, the actual number of downlink carriers configured by the second device for the first device always exceeds or is not less than the maximum downlink receiving capability of the first device. Specifically, the maximum number of downlink carriers that the first device can simultaneously receive downlink signals refers to the maximum downlink receiving capability of the first device. The value of K represents the downlink receiving capability of the first device. J represents the actual number of downlink carriers configured by the second device for the first device. J can be greater than K, meaning that the second device can configure a number of downlink carriers for the first device that exceeds the maximum number of downlink carriers that the first device can simultaneously receive downlink signals. In other words, the actual number of downlink carriers configured by the second device for the first device exceeds the maximum downlink concurrency capability of the first device. For example, if the value of K is 3, the maximum downlink concurrency capability of the first device is 3 downlink carriers, and the value of J can be greater than the value of K. For example, if the value of J is 5, the actual number of downlink carriers configured by the second device for the first device is 5. 5 is greater than 3, indicating that the actual number of downlink carriers configured by the second device for the first device exceeds the maximum downlink concurrency capability of the first device. Alternatively, the value of J may be less than or equal to the value of K. For example, if the value of J is 3 and the value of K is 3, this indicates that the actual number of downlink carriers configured by the second device for the first device is equal to the maximum downlink concurrency capability of the first device.

[0157] It should be noted that in the embodiment of the present application, the J indicated by the second configuration information may be greater than K, which means that the second configuration information has the actual number of downlink carriers configured for the first device that exceeds the maximum downlink receiving capability of the first device. Of course, it is not limited to that the actual number of downlink carriers configured by the second device for the first device may exceed the maximum downlink receiving capability of the first device, or the actual number of downlink carriers configured by the second device for the first device may not exceed the maximum downlink receiving capability of the first device. In the embodiment of the present application, the second device has the function of configuring the actual number of downlink carriers configured for the first device that exceeds the maximum downlink receiving capability of the first device, but it does not necessarily mean that "the second device has the actual number of downlink carriers configured for the first device that exceeds the maximum downlink receiving capability of the first device". It is specifically necessary to determine the actual number of downlink carriers configured by the second device for the first device according to the application scenario. Similarly, the J indicated by the second configuration information may be greater than K, but it does not necessarily mean that "the J indicated by the second configuration information must be greater than K". The J indicated by the second configuration information may also be less than or equal to K, which is not limited here.

[0158] In some embodiments of the present application, the second device may configure at least J downlink carriers for the first device, i.e., the second device may configure J downlink carriers for the first device, or the second device may configure J+1 downlink carriers for the first device, or the second device may configure J+2 downlink carriers for the first device. In the embodiments of the present application, the actual number of downlink carriers configured by the second device for the first device is not limited. In particular, J = 3, or J = K.

[0159] In some embodiments of the present application, in addition to performing the aforementioned step 401, the information transmission method provided in the embodiments of the present application further includes:

[0160] The second device receives the second capability information from the first device;

[0161] The second device determines, based on the second capability information, that the first device is capable of determining a downlink carrier for receiving information from more than K downlink carriers; and / or,

[0162] The second device determines, based on the second capability information, that the first device is capable of determining a downlink carrier for receiving information from a maximum of V downlink carriers, where at least one element in a value set of V is a positive integer greater than K; and / or,

[0163] The second device determines K according to the second capability information; and / or,

[0164] The second device determines, based on the second capability information, that the first device can support determining a downlink carrier for receiving information from a maximum of B enabled downlink carriers. For example, B is a positive integer greater than K.

[0165] In some embodiments of the present application, in addition to performing the aforementioned step 411, the information transmission method provided in the embodiments of the present application further includes:

[0166] The first device sends second capability information to the second device;

[0167] The second capability information is used to indicate that the first device is capable of determining a downlink carrier for receiving information from more than K downlink carriers; and / or,

[0168] The second capability information is used to indicate that the first device is capable of determining a downlink carrier for receiving information from a maximum of V downlink carriers, where at least one element in a value set of V is a positive integer greater than K; and / or,

[0169] The second capability information is used to indicate K; and / or,

[0170] The second capability information is used to indicate that the first device can support determining a downlink carrier for receiving information from a maximum of B enabled downlink carriers. For example, B is a positive integer greater than K.

[0171] The first device generates second capability information and sends the second capability information to the second device. The second capability information is used to indicate the first device's ability to support downlink carriers, so that the second device determines the first device's ability to support downlink carriers based on the received second capability information. The second device can configure the actual number of downlink carriers for the first device based on the first device's ability to support downlink carriers.

[0172] Specifically, the second capability information may indicate the first device's capability for multiple downlink carriers. For example, the second capability information may indicate that the first device is capable of determining a downlink carrier for receiving information from more than K downlink carriers. The second capability information reflects that the first device has the capability to determine a downlink carrier for receiving information from more than K downlink carriers. That is, through the second capability information, the second device can determine that the first device is capable of determining a downlink carrier for receiving information from more than K downlink carriers. "Reflection" means that the second capability information may indicate directly, indirectly, explicitly, implicitly, or otherwise. Furthermore, the second capability information indicates that the first device is capable of determining a downlink carrier for receiving information from more than K downlink carriers. This indication may be direct, indirect, explicit, or implicit. The second capability information reflects that "the first device is capable of determining a downlink carrier for receiving information from more than K downlink carriers." "The first device is capable of determining a downlink carrier for receiving information from more than K downlink carriers" is the result reflected by the second capability information. The second capability information may indicate the above result directly or indirectly, without limitation. For the description of “reflection” in the subsequent embodiments, please refer to here, and “reflection” will not be described in detail later.

[0173] In the embodiments of the present application, determining a downlink carrier for receiving information refers to determining by the first device potential or candidate downlink carriers that can be used for downlink reception, and does not refer to downlink carriers that the first device can actually receive in parallel downlink. The first device can determine, from among the candidate downlink carriers, downlink carriers that can actually be received in parallel downlink. That is, determining a downlink carrier for receiving information refers to determining which downlink carriers may be used for actual downlink transmission. Alternatively, the number of candidate downlink carriers may exceed the maximum number of downlink carriers that the first device can actually receive in parallel downlink.

[0174] In some embodiments of the present application, the second device can configure a maximum of Q downlink carriers for the first device, where Q is a positive integer greater than K.

[0175] The second device is capable of configuring a maximum of Q downlink carriers for the first device, that is, the second device has the ability to configure a maximum number of downlink carriers of Q for the first device, where Q is greater than K. For example, the value of K is 3, and the value of Q may be 4. Optionally, the first configuration information may be used to instruct the second device to configure a maximum of Q downlink carriers for the first device, that is, the first configuration information is capable of configuring a maximum of Q downlink carriers for the user equipment, and the maximum number of downlink carriers that the first device can simultaneously receive is K, where Q is a positive integer greater than 1, and K is a positive integer less than Q.

[0176] In some embodiments of the present application, the second capability information is used to enable the second device to determine that: the first device supports the number of downlink carriers configured by the second device for the first device to be greater than K; and / or,

[0177] The second capability information is used to enable the second device to determine that the maximum number of downlink carriers that the first device can support, configured by the second device for the first device, is V; and / or,

[0178] The second capability information is used to enable the second device to determine that the maximum number of downlink carriers that the first device can simultaneously receive downlink signals is K; and / or,

[0179] The second capability information is used to enable the second device to determine that the first device can support determining a downlink carrier for receiving information from a maximum of B enabled downlink carriers. For example, B is a positive integer greater than K.

[0180] Specifically, the second capability information is used to indicate that the first device is capable of determining a downlink carrier for sending information from more than K downlink carriers, so that the second device determines, based on the received second capability information, that the number of downlink carriers supported by the first device and configured by the second device for the first device is greater than K. The second device can configure the actual number of downlink carriers for the first device based on the capability of the first device to support downlink carriers.

[0181] Specifically, the second capability information is used to indicate that the first device can support determining the downlink carrier for sending information from a maximum of V downlink carriers, so that the second device determines, based on the received second capability information, that the first device can support the maximum number of downlink carriers configured by the second device to the first device, which is V. The second device can configure the actual number of downlink carriers for the first device based on the capability of the first device to support downlink carriers.

[0182] Specifically, the second capability information is used to indicate K, so that the second device determines that the maximum number of downlink carriers that the first device can simultaneously receive downlinks is K based on the received second capability information. The second device can configure the actual number of downlink carriers for the first device based on the capability of the first device to support downlink carriers.

[0183] As an example, the first device is a user device, and the second device is a peer device of the user device. For example, the peer device may be a base station, a machine-type communication terminal, or a communication terminal for connected vehicle services. The user device may also report second capability information to the network device. The second capability information is used to allow the peer device to determine: whether the user device supports the number Q of downlink carriers configured by the peer device for the user device, and Q is equal to K; or whether the user device supports the number Q of downlink carriers configured by the peer device for the user device, and Q is greater than K. K is the maximum number of downlink carriers that the user device can simultaneously transmit downlink information.

[0184] Specifically, the first capability information is used to indicate that the first device can support determining a downlink carrier for receiving information from a maximum of B enabled downlink carriers. For example, B is a positive integer greater than K. Here, enabling means that the second device activates the downlink carrier, or the second device configures the downlink carrier so that the carrier can be used by the first device. Through the first capability information, the second device can determine that the first device can support a maximum of B enabled downlink carriers, and the second device can determine the downlink carrier available to the first device from the maximum of B enabled downlink carriers.

[0185] In some embodiments of the present application, in addition to performing the aforementioned step 401, the information transmission method provided in the embodiments of the present application further includes:

[0186] The second device sends fourth configuration information to the first device, where the fourth configuration information is used to indicate the downlink carriers and / or the number of downlink carriers enabled by the second device for the first device. The number of downlink carriers enabled by the second device for the first device can be greater than K.

[0187] In addition to sending the second configuration information to the first device, the second device may also send fourth configuration information to the first device. The second configuration information and the fourth configuration information may be sent to the first device simultaneously. For example, the second device may carry the second configuration information and the fourth configuration information in one signaling, information element, or field. Alternatively, the second configuration information and the fourth configuration information may be sent to the first device separately via different signaling, information elements, or fields, which is not limited here.

[0188] In an embodiment of the present application, the fourth configuration information is used to indicate the downlink carriers and / or the number of enabled downlink carriers that the second device enables for the first device. For example, the fourth configuration information can directly indicate the downlink carriers and / or the number of enabled downlink carriers that the second device enables for the first device. The first device determines the downlink carriers and / or the number of enabled downlink carriers that the second device enables for the first device through the fourth configuration information. For another example, the fourth configuration information can directly indicate the number of disabled downlink carriers and / or disabled downlink carriers, and the first device determines the number of disabled downlink carriers and / or disabled downlink carriers through the fourth configuration information, and then determines the number of enabled downlink carriers based on the total number of downlink carriers and the number of disabled downlink carriers. Among them, the number of downlink carriers enabled by the second device for the first device can be greater than K, and there is no limitation on the specific value of the number of downlink carriers enabled by the second device for the first device.

[0189] 402. The second device determines W downlink carriers from the J downlink carriers, where W is a positive integer less than or equal to K. The W downlink carriers are used to send information. For example, the second device uses the downlink carriers to send information to the first device, or the third device uses the downlink carriers to send information to the first device, or the second device and the third device use the downlink carriers to send information to the first device.

[0190] 412. The first device determines W downlink carriers from J downlink carriers, where W is a positive integer less than or equal to K.

[0191] In an embodiment of the present application, after the first device determines, through the second configuration information, that the second device has configured J downlink carriers for the first device, the first device may further determine the downlink carriers that the first device can actually use. For example, the first device performs carrier selection and determines the downlink carriers that the first device can actually use. The first device then notifies the second device of the downlink carriers that the first device can actually use. For another example, the first device receives a notification from the second device and determines the downlink carriers that the first device can actually use based on the notification.

[0192] In some embodiments of the present application, step 412, in which the first device determines W downlink carriers from J downlink carriers, includes:

[0193] The first device receives fourth configuration information from the second device, where the fourth configuration information is used to indicate a downlink carrier and / or the number of downlink carriers enabled by the second device for the first device, and the number of downlink carriers enabled by the second device for the first device can be greater than K.

[0194] The first device determines W uplink carriers from the downlink carriers enabled by the second device for the first device.

[0195] In an embodiment of the present application, the fourth configuration information is used to indicate the number of downlink carriers enabled by the second device for the first device. For example, the fourth configuration information can directly indicate the number of downlink carriers enabled by the second device for the first device, and the first device determines the number of downlink carriers and / or enabled downlink carriers enabled by the second device for the first device through the fourth configuration information. For another example, the fourth configuration information can directly indicate the number of disabled downlink carriers, and the first device determines the number of disabled downlink carriers through the fourth configuration information, and then determines the number of enabled downlink carriers based on the total number of downlink carriers and the number of disabled downlink carriers. Among them, the number of downlink carriers enabled by the second device for the first device can be greater than K, and there is no limitation on the specific value of the number of downlink carriers enabled by the second device for the first device.

[0196] An example is given below: the second device configures J downlink carriers for the first device, where J = 5, K is the maximum number of downlink carriers that the first device can simultaneously perform downlink transmission, K = 3, and the third configuration information indicates that the second device enables 4 downlink carriers for the first device, then the first device determines W downlink carriers from the 4 enabled downlink carriers, where W = 2. Therefore, the first device can determine 2 downlink carriers from the 4 enabled downlink carriers, and the 2 downlink carriers are the downlink carriers used by the first device for downlink transmission. In the embodiment of the present application, the first terminal device has the ability to flexibly select carriers in more carriers than its downlink concurrency capability, so the first device can achieve flexible use of spectrum resources.

[0197] In the subsequent embodiments, the second device uses a downlink carrier to send information to the first device as an example. However, in the embodiments of the present application, a third device can also use a downlink carrier to send information to the first device, or the second and third devices can use a downlink carrier to send information to the first device. For example, the second device is a macro base station and the third device is a micro base station.

[0198] 403. The second device sends information to the first device in W downlink carriers.

[0199] 413. The first device receives information from the second device in W downlink carriers.

[0200] In this embodiment of the present application, the first device determines that W downlink carriers are downlink carriers used by the first device for downlink reception. The first device can transmit downlink information with the second device on the W downlink carriers. For example, the first device sends information to the second device on the W downlink carriers, thereby enabling communication between the first device and the second device.

[0201] In some embodiments of the present application, T is greater than J, where J is the number of downlink carriers configured by the second device for the first device; and / or,

[0202] L is greater than K, where K is the maximum number of downlink carriers that the first device can simultaneously receive downlink signals.

[0203] In some embodiments of the present application, M is greater than Q, where Q is the maximum number of downlink carriers that the second device can configure for the first device.

[0204] For example, in an embodiment of the present application, the first device is a user device, and the second device is a peer device of the user device. For example, the peer device may be a base station, or the peer device is a machine type communication terminal, or the peer device is a communication terminal for vehicle-to-vehicle services, etc. One application scenario is that the number of downlink carriers configured by the peer device for the user device is less than the number of uplink carriers configured by the peer device for the user device. That is, T is greater than J, and / or Q is less than M. For example, in an embodiment of the present application, a typical application scenario is that the number of downlink carriers that the user device can simultaneously receive in parallel is less than the number of uplink carriers that the user device can simultaneously transmit in parallel. That is, K is less than L.

[0205] In the embodiment of the present application, M can be greater than Q, that is, the uplink and downlink carriers do not need to appear in pairs, which solves the limitation on spectrum resource utilization. The maximum number of downlink parallel reception carriers of the user equipment is less than the maximum number of uplink concurrent reception carriers of the user equipment, which does not increase the complexity of the user equipment. It is suitable for services mainly based on the above behaviors and meets the user equipment's needs for more uplink carriers.

[0206] In an embodiment of the present application, a user device notifies a peer device that it has the ability to flexibly select carriers from more carriers than its uplink concurrency capability and / or parallel reception capability. The peer device can configure more uplink carriers for the user device than its concurrency capability, or more downlink carriers than its parallel reception capability. The user device can then flexibly select carriers from more carriers, selecting the optimal carrier resource, improving the data rate, reducing the complexity of the user device, and saving the power consumption of the user device. For example, an embodiment of the present application reduces the uplink concurrency complexity and / or downlink parallel reception complexity of the user device.
