Description

Technical Field

[0001] This application relates to the field of mobile communication technologies, and in particular, to a method and apparatus for sending information and receiving information. Background Art

[0002] In a Long Term Evolution (LTE) system, a terminal device supports simultaneous access to two network devices, and this access mode is called Dual Connectivity (DC). One of the network devices is the primary network device, and the other network device is the secondary network device. During the development and evolution of wireless communication systems, operators will deploy both 5th generation (5G) New Radio (NR) systems and Long Term Evolution (LTE) systems simultaneously. Therefore, in a dual-connectivity scenario, a terminal device supports simultaneous access to an LTE network device and an NR network device. Since LTE is also known as Evolved Universal Terrestrial Radio Access (E-UTRA), this access mode is called E-UTRA NR Dual Connectivity (EN-DC). In the EN-DC mode, the LTE network device is the primary network device, and the NR network device is the secondary network device. In another dual-connectivity scenario, it is also possible to support NR E-UTRA Dual Connectivity (NE-DC), that is, the NR network device is the primary network device, and the LTE network device is the secondary network device. Since terminals in EN-DC and NE-DC will both access network devices of two different radio access technologies, these DC modes can also be collectively referred to as Multi-RAT Dual Connectivity (MR-DC). Of course, there are also other dual-connectivity scenarios, such as a terminal device supporting simultaneous access to two LTE network devices, or a terminal device supporting simultaneous access to two NR network devices.

[0003] However, currently, when a terminal device and a network device communicate using dual-connectivity technology, there is still a problem that the communication efficiency needs to be improved. Summary of the Invention

[0004] This application provides a method and apparatus for sending information and receiving information, which helps to improve the communication efficiency between network devices and terminal devices.

[0005] In a first aspect, the present application provides a method for sending information, including: generating a first message, where the first message includes first indication information, and the first indication information is used to indicate the maximum number of transmit antennas M that the terminal device supports in total when simultaneously sending signals on at least two uplink carriers, or is used to indicate whether the transmit antennas for the terminal device to send signals on at least two uplink carriers share; and sending the first message to a network device.

[0006] In a second aspect, the present application provides a method for receiving information, including: receiving a first message from a terminal device, where the first message includes first indication information, and the first indication information is used to indicate the maximum number of transmit antennas M that the terminal device supports in total when simultaneously sending signals on at least two uplink carriers, or is used to indicate whether the transmit antennas for the terminal device to send signals on at least two uplink carriers share; and obtaining the first indication information in the first message.

[0007] Based on this solution, the network device can determine the configuration of the transmit antennas of the terminal device through the first indication information, so that the network device can distinguish terminal devices with different transmit antenna capabilities, and thus the network device can adopt appropriate scheduling strategies for terminal devices with different transmit antenna capabilities, which helps to improve the communication efficiency between the terminal device and the network device.

[0008] In a possible implementation method, according to the first indication information, determine the maximum number of transmit antennas that the terminal device supports in total.

[0009] Based on the above first aspect, or a possible implementation manner of the first aspect, or the second aspect:

[0010] In a possible implementation method, the at least two uplink carriers include a first uplink carrier and a second uplink carrier. When the first indication information is used to indicate the maximum number of transmit antennas that the terminal device supports in total when simultaneously sending signals on the first uplink carrier and the second uplink carrier, if the maximum number of transmit antennas indicated by the first indication information is less than the sum of the first maximum number of transmit antennas supported by the terminal device when only sending signals on the first uplink carrier and the second maximum number of transmit antennas supported by the terminal device when only sending signals on the second uplink carrier, then the handover time when the terminal device handovers between the first uplink carrier and the second uplink carrier is equal to t1, and t1 is greater than 0.

[0011] Based on this solution, by setting a switching time, some antennas of the terminal device can be shared for use. That is, the shared transmit antennas can, through the switching time, be used for transmitting signals of the first uplink carrier or for transmitting signals of the second uplink carrier, which is conducive to improving the utilization efficiency of the transmit antennas, and thus improves the communication efficiency between the terminal device and the network device.

[0012] In a possible implementation method, among the at least two uplink carriers, there are a first uplink carrier and a second uplink carrier. When the first indication information is used to indicate the maximum number of transmit antennas that the terminal device supports in total when transmitting signals on the first uplink carrier and the second uplink carrier simultaneously, if the maximum number of transmit antennas indicated by the first indication information is less than the sum of the first maximum number of antennas supported by the terminal device when transmitting signals only on the first uplink carrier and the second maximum number of antennas supported by the terminal device when transmitting signals only on the second uplink carrier,

[0013] the switching time when the terminal device switches between using N1 transmit antennas to transmit signals on the first uplink carrier and using N2 transmit antennas to transmit signals on the second uplink carrier is equal to t1, where N1 + N2 is greater than the maximum number of transmit antennas indicated by the first indication information, and t1 is greater than 0; and / or,

[0014] the switching time when the terminal device switches between using N3 transmit antennas to transmit signals on the first uplink carrier and using N4 transmit antennas to transmit signals on the second uplink carrier is equal to t2, where N3 + N4 is less than or equal to the maximum number of transmit antennas indicated by the first indication information, and t2 is greater than or equal to 0.

[0015] In a possible implementation method, among the at least two uplink carriers, there are a first uplink carrier and a second uplink carrier. When the first indication information is used to indicate the maximum number of transmit antennas that the terminal device supports in total when transmitting signals on the first uplink carrier and the second uplink carrier simultaneously, if the maximum number of transmit antennas indicated by the first indication information is equal to the sum of the first maximum number of antennas supported by the terminal device when transmitting signals only on the first uplink carrier and the second maximum number of antennas supported by the terminal device when transmitting signals only on the second uplink carrier, then the switching time when the terminal device switches between the first uplink carrier and the second uplink carrier is equal to t2, and t2 is greater than or equal to 0.

[0016] In a possible implementation method, the at least two uplink carriers include a first uplink carrier and a second uplink carrier. When the first indication information is used to indicate whether the transmission antennas for the terminal device to transmit signals on the first uplink carrier and the second uplink carrier share, if the first indication information indicates that the transmission antennas for the terminal device to transmit signals on the first uplink carrier and the second uplink carrier share, then the handover time when the terminal device switches between the first uplink carrier and the second uplink carrier is equal to t1, and t1 is greater than 0.

[0017] In a possible implementation method, the at least two uplink carriers include a first uplink carrier and a second uplink carrier. When the first indication information is used to indicate whether the transmission antennas for the terminal device to transmit signals on the first uplink carrier and the second uplink carrier share, if the first indication information indicates that the transmission antennas for the terminal device to transmit signals on the first uplink carrier and the second uplink carrier share,

[0018] then the handover time when the terminal device switches between using N1 transmission antennas to transmit signals on the first uplink carrier and using N2 transmission antennas to transmit signals on the second uplink carrier is equal to t1, and t1 is greater than 0, where N1 + N2 > M1 + M2 - X; and / or,

[0019] the handover time when the terminal device switches between using N3 transmission antennas to transmit signals on the first uplink carrier and using N4 transmission antennas to transmit signals on the second uplink carrier is equal to t2, and t2 is greater than or equal to 0, where N3 + N4 <= M1 + M2 - X;

[0020] where M1 is the first maximum number of transmission antennas supported by the terminal device when transmitting signals only on the first uplink carrier, M2 is the second maximum number of transmission antennas supported by the terminal device when transmitting signals only on the second uplink carrier, and X is the number of shared transmission antennas between the transmission antennas for the terminal device to transmit signals on the first uplink carrier and the transmission antennas for the terminal device to transmit signals on the second uplink carrier.

[0021] In a possible implementation method, the at least two uplink carriers include a first uplink carrier and a second uplink carrier. When the first indication information is used to indicate whether the transmit antennas for the terminal device to send signals on the first uplink carrier and the second uplink carrier are shared, if the first indication information indicates that the transmit antennas for the terminal device to send signals on the first uplink carrier and the second uplink carrier are not shared, the handover time when the terminal device handovers between the first uplink carrier and the second uplink carrier is equal to t2, and t2 is greater than or equal to 0.

[0022] In a possible implementation method, the first message further includes second indication information, and the second indication information is used to indicate the number of shared transmit antennas between the transmit antenna for the terminal device to send signals on the first uplink carrier and the transmit antenna for the terminal device to send signals on the second uplink carrier.

[0039] In order to make the objectives, technical solutions, and advantages of this application clearer, the following will further describe this application in detail with reference to the accompanying drawings. The specific operation methods in the method embodiments can also be applied to the apparatus embodiments or system embodiments. Among them, in the description of this application, unless otherwise specified, the meaning of "a plurality of" is two or more.

[0040] The scenario to which this application is applied may be a scenario where a terminal device operates in a dual-connection scenario. In the dual-connection scenario, the terminal device is simultaneously connected to a primary network device and a secondary network device. It should be noted that the primary network device and the secondary network device may be deployed at the same site or at different sites. Moreover, when the primary network device and the secondary network device can be deployed at the same site, the primary network device and the secondary network device may share the same set of hardware devices or use different hardware devices. As Figure 1A shown, it is a schematic diagram of a dual-connection scenario where the primary network device and the secondary network device are deployed at the same site. As Figure 1B shown, it is a schematic diagram of a dual-connection scenario where the primary network device and the secondary network device are deployed at different sites.

[0041] In this application, the terminal device may be a wireless terminal device capable of receiving scheduling and indication information from a network device. The wireless terminal device may be a device that provides voice and / or data connectivity to a user, or a handheld device with wireless connection capabilities, or other processing devices connected to a wireless modem. The terminal device may communicate with one or more core networks or the Internet via a radio access network (e.g., radio access network, RAN). The terminal device may be a mobile terminal device, such as a mobile phone (or "cellular" phone, mobile phone), computer, and data card. For example, it may be a portable, pocket-sized, handheld, computer-integrated, or vehicle-mounted mobile device that exchanges voice and / or data with the radio access network. For example, personal communication service (PCS) phones, cordless phones, session initiation protocol (SIP) phones, wireless local loop (WLL) stations, personal digital assistants (PDAs), tablets (Pads), computers with wireless transceiver functions, and other devices. The wireless terminal device may also be referred to as a system, subscriber unit, subscriber station, mobile station, mobile station (MS), remote station, access point (AP), remote terminal device, access terminal device, user terminal device, user agent, user station (SS), customer premises equipment (CPE), terminal, user equipment (UE), mobile terminal (MT), etc. In addition, the terminal device may also be a vehicle, in-vehicle device, or wearable device capable of communicating with the network device.

[0042] A network device (including a primary network device and a secondary network device) is an entity in the network side for transmitting or receiving signals, and can be an access network device. The network device can be a device for communicating with a mobile device. The network device can be an access point (AP) in wireless local area networks (WLANs), an evolved Node B (eNB or eNodeB) in LTE, or a relay station or access point, or a new generation Node B (gNodeB) in a 5G New Radio (NR) system, or a network device in a future evolved public land mobile network (PLMN), etc.

[0043] In the embodiments of the present application, the network device provides services for a cell, and the terminal device communicates with the network device through the communication resources used by the cell (for example, frequency domain resources, or in other words, spectrum resources). The cell can be a cell corresponding to the network device (such as a base station). The cell can belong to a macro base station or a base station corresponding to a small cell. Here, the small cell can include: Metro cell, Micro cell, Picocell, Femto cell, etc. These small cells have the characteristics of small coverage range and low transmission power, and are suitable for providing high-rate data transmission services. In addition, in other possible cases, the network device can be other devices that provide wireless communication functions for the terminal device. The embodiments of the present application do not limit the specific technologies and specific device forms adopted by the network device. For the convenience of description, in the embodiments of the present application, the device that provides wireless communication functions for the terminal device is called a network device.

[0044] In a dual-connection scenario, there are two cell groups, namely the Master Cell Group (MCG) and the Secondary Cell Group (SCG). Among them, the MCG includes a Primary Cell (PCell), and optionally, can additionally include one or more Secondary Cells (Scells). The SCG includes a Primary Secondary Cell (PSCell), and optionally, can additionally include one or more SCells. The network device that manages the MCG is called the primary network device, and the network device that manages the SCG is called the secondary network device.

[0045] In the embodiments of the present application, the primary network device is one of an LTE network device (such as an eNB), a 5G network device (such as a gNB), or a network device in a future communication system, and the secondary network device is also one of an LTE network device, a 5G network device, or a network device in a future communication system. Moreover, the primary network device and the secondary network device can be network devices of the same radio access technology (RAT), for example, both are eNBs, or they can be network devices of different RATs, for example, the primary network device is an eNB and the secondary network device is a gNB. The present application does not limit the RATs of the primary network device and the secondary network device.

[0046] It should be noted that a cell may include a downlink carrier and at least one uplink carrier. In one case, a cell includes a downlink carrier and an uplink carrier, and the downlink carrier and the uplink carrier may correspond to the same frequency band or different frequency bands. In another case, a cell includes a downlink carrier and two uplink carriers, and the downlink carrier uses the same frequency band as one of the two uplink carriers and a different frequency band from the other uplink carrier. Therefore, the cell in the present application corresponds to the downlink carrier.

[0047] A cell group may include at least one cell. Generally, different cell groups can be considered to correspond to different network devices. Different cells in the same cell group may correspond to the same network device or different network devices, which is not limited in the present application.

[0048] In the present application, the terminal device can simultaneously transmit signals on at least two uplink carriers. These uplink carriers can come from different cell groups or the same cell group. When they come from the same cell group, the at least two uplink carriers may correspond to the same downlink carrier, that is, belong to the same cell, or may correspond to different downlink carriers, that is, belong to different cells.

[0049] For example, when the terminal device simultaneously transmits signals on two uplink carriers, the two uplink carriers can be respectively referred to as the first uplink carrier and the second uplink carrier. When the first uplink carrier and the second uplink carrier in the method of the present application come from the same cell group, the method can be applied to non-DC scenarios, such as carrier aggregation scenarios or supplementary uplink (SUL) scenarios. It should be noted that when the first uplink carrier and the second uplink carrier come from the same cell group, it can also be considered that there is no cell group at this time, but only different uplink carriers.

[0050] Currently, terminal devices supporting MR-DC have the following three antenna configurations, or are referred to as three different transmission antenna capabilities of the terminal device:

[0051] 1) Configuration 1: K1 transmit antennas (Tx) are allocated to NR, and K2 transmit antennas are allocated to LTE.

[0052] Based on this Configuration 1, the terminal device can simultaneously transmit signals on the uplink carrier of NR and the uplink carrier of LTE. Among them, the uplink carrier of NR is called the first uplink carrier, and the uplink carrier of LTE is called the second uplink carrier; alternatively, the uplink carrier of NR is called the second uplink carrier, and the uplink carrier of LTE is called the first uplink carrier.

[0053] The first maximum number of transmit antennas supported when the terminal device transmits signals only on the first uplink carrier is denoted as M1, the second maximum number of transmit antennas supported when the terminal device transmits signals only on the second uplink carrier is denoted as M2, and the total maximum number of transmit antennas supported when the terminal device simultaneously transmits signals on the first uplink carrier and the second uplink subcarrier is denoted as M.

[0054] Taking the uplink carrier of NR as the first uplink carrier and the uplink carrier of LTE as the second uplink carrier as an example, then M1 = K1, M2 = K2, and M = M1 + M2 = K1 + K2.

[0055] It can be seen that in this Configuration 1, the transmit antennas allocated to NR and the transmit antennas allocated to LTE are not shared.

[0056] 2) Configuration 2: K3 transmit antennas are allocated to NR, and K4 transmit antennas are available for time-division sharing between LTE and NR.

[0057] Based on this Configuration 2, taking the uplink carrier of NR as the first uplink carrier and the uplink carrier of LTE as the second uplink carrier as an example, then M1 = K3 + K4, M2 = K4, M = K3 + K4, and M < M1 + M2.

[0058] It can be seen that in this Configuration 2, the transmit antennas allocated to NR and the transmit antennas allocated to LTE are shared.

[0059] 3) Configuration 3: K5 transmit antennas are allocated to NR, and K6 transmit antennas are allocated to LTE.

[0060] The main difference between this Configuration 3 and the above Configuration 1 is that: the value of K5 is different from that of K1, and / or the value of K6 is different from that of K2.

[0061] Taking the uplink carrier of NR as the first uplink carrier and the uplink carrier of LTE as the second uplink carrier as an example, then M1 = K5, M2 = K6, and M = M1 + M2 = K5 + K6.

[0062] It can be seen that in this Configuration 3, the transmit antennas allocated to NR and the transmit antennas allocated to LTE are not shared.

[0063] However, for a terminal device that communicates based on the above scenario, there is a need to switch between the LTE uplink carrier and the NR uplink carrier to send uplink signals. However, in the prior art, since the network device cannot know the configuration of the transmitting antenna of the terminal device, the network device cannot distinguish terminal devices with different transmitting antenna capabilities, resulting in the network device being unable to adopt an appropriate scheduling strategy for the terminal device, which affects the communication efficiency between the terminal device and the network device.

[0064] It should be noted that in this application, the transmitting antenna can also be referred to as a transmitting link, or a radio frequency link, or a radio frequency channel, etc.

[0065] It should be noted that this application does not limit the magnitude of the values of K1, K2, K3, K4, K5, and K6, and some of these values can be equal.

[0066] As Figure 2 shown, it is a schematic diagram of the antenna configuration of the terminal device. In this example:

[0067] For Configuration 1, K1 = 1, K2 = 1, a total of 2 transmitting antennas, and M1 = 1, M2 = 1, M = 2.

[0068] For Configuration 2, K3 = 1, K4 = 1, a total of 2 transmitting antennas, and M1 = 2, M2 = 1, M = 2.

[0069] For Configuration 3, K5 = 2, K6 = 1, a total of 3 transmitting antennas, and M1 = 2, M2 = 1, M = 3.

[0070] The above three antenna configurations respectively correspond to three transmitting antenna capabilities of the terminal device. To enable the network device to distinguish terminal devices with different transmitting antenna capabilities and thus adopt an appropriate scheduling strategy for different terminal devices, the network device needs to know the transmitting antenna capabilities of the terminal device.

[0071] This application provides a method for a terminal device to report its transmitting antenna capabilities, that is, the terminal device informs the network device which one of the above three configurations it supports.

[0072] As Figure 3 shown, it is a method for a terminal device to send and receive information provided by this application. The method includes the following steps:

[0073] Step 301, the terminal device generates a first message, and the first message includes first indication information.

[0074] The first indication information may also be referred to as transmission antenna capability indication information, or antenna capability indication information, or antenna configuration indication information, etc. It should be noted that the antenna here may also be replaced with descriptions strongly related to the transmission antenna, such as "radio frequency channel" or "radio frequency link" or "power amplifier". That is to say, the first indication information may also be referred to as radio frequency channel capability indication information, or radio frequency link capability indication information, or power amplifier capability indication information. This embodiment does not limit the name of the first indication information.

[0075] In a specific implementation, the first message may be, for example, a message for the terminal device to report its capabilities. This message includes the above-mentioned first indication information in this application, and may also include indication information of other capabilities, such as the capability indication information of the modulation method supported by the terminal device, and the capability indication information of the uplink multi-antenna precoding supported by the terminal device, etc. Therefore, the terminal device usually first determines the first indication information according to its own capabilities, and then encapsulates the first indication information into the first message to generate the first message.

[0076] The first indication information is used to indicate the maximum number of transmission antennas (denoted as M) that the terminal device supports in total when simultaneously transmitting signals on at least two uplink carriers, or to indicate whether the transmission antennas for the terminal device to transmit signals on at least two uplink carriers share.

[0077] Step 302, the terminal device sends the first message to the network device. Correspondingly, the network device can receive the first message.

[0078] Step 303, the network device obtains the first indication information in the first message.

[0079] After obtaining the first indication information, the network device can determine the maximum number of transmission antennas that the terminal device supports in total according to the first indication information. Furthermore, the network device can determine which one of the above three configurations the antenna configuration of the terminal device belongs to according to the maximum number of transmission antennas that the terminal device supports in total.

[0080] For example, when the first indication information is used to indicate the maximum number of transmit antennas M that the terminal device supports in total when transmitting signals simultaneously on the first uplink carrier and the second uplink carrier, or to indicate whether the transmit antennas for the terminal device to transmit signals on the first uplink carrier and the second uplink carrier share antennas, the network device may determine which of the above three configurations the antenna configuration of the terminal device belongs to according to the first maximum number of antennas (denoted as M1) supported by the terminal device when transmitting signals only on the first uplink carrier, the second maximum number of antennas (denoted as M2) supported by the terminal device when transmitting signals only on the second uplink carrier, and the maximum number of transmit antennas M that the terminal device supports in total. Among them, the first maximum number of antennas M1 supported by the terminal device when transmitting signals only on the first uplink carrier and the second maximum number of antennas M2 supported by the terminal device when transmitting signals only on the second uplink carrier may be predefined by the protocol or pre-reported by the terminal device to the network device.

[0081] It should be noted that the first uplink carrier and the second uplink carrier in this embodiment may be uplink carriers from different cell groups. For example, the first uplink carrier comes from the primary cell group and the second uplink carrier comes from the secondary cell group, and of course, it can also be the other way around. Further, the cell groups corresponding to the first uplink carrier and the second uplink carrier may belong to the same radio access technology or may correspond to different radio access technologies. For example, the first uplink carrier corresponds to LTE and the second uplink carrier corresponds to NR, and of course, it can also be the other way around. The first uplink carrier and the second uplink carrier in this embodiment may be different uplink carriers from the same cell group.

[0082] It should be noted that Figure 3 The network device in the embodiment may be a primary network device or a secondary network device, which is not limited in this application.

[0083] Based on the above solution, the terminal device enables the network device to distinguish terminal devices with different transmit antenna capabilities through the first indication information, so that the network device can adopt an appropriate scheduling strategy for terminal devices with different transmit antenna capabilities, which helps to improve the communication efficiency between the terminal device and the network device.

[0084] Several different implementation methods of the above first indication information are given below.

[0085] Method 1: The first indication information is used to indicate the maximum number of transmit antennas M that the terminal device supports in total when transmitting signals simultaneously on the first uplink carrier and the second uplink carrier.

[0086] For this Method 1, it is divided into the following two cases:

[0087] Case 1: The maximum number of transmit antennas M indicated by the first indication information is less than the sum of the first maximum number of transmit antennas M1 supported by the terminal device when transmitting signals only on the first uplink carrier and the second maximum number of transmit antennas M2 supported by the terminal device when transmitting signals only on the second uplink carrier, that is, M < M1 + M2.

[0088] For this Case 1, since M < M1 + M2, the network device can determine that the antenna configuration of the terminal device should belong to Configuration 2 above. That is, the transmit antennas of the terminal device for transmitting signals on the first uplink carrier and the second uplink carrier are shared.

[0089] Case 2: The maximum number of transmit antennas M indicated by the first indication information is equal to the sum of the first maximum number of transmit antennas M1 supported by the terminal device when transmitting signals only on the first uplink carrier and the second maximum number of transmit antennas M2 supported by the terminal device when transmitting signals only on the second uplink carrier, that is, M = M1 + M2.

[0090] For this Case 2, since M = M1 + M2, the network device can determine that the antenna configuration of the terminal device should belong to Configuration 1 or Configuration 3 above, that is, the transmit antennas of the terminal device for transmitting signals on the first uplink carrier and the second uplink carrier are not shared.

[0091] Furthermore, the network device can determine the antenna configuration of the terminal device as Configuration 1 or Configuration 3 according to the first maximum number of transmit antennas M1 supported by the terminal device when transmitting signals only on the first uplink carrier and the second maximum number of transmit antennas M2 supported by the terminal device when transmitting signals only on the second uplink carrier. For example, if M1 = K1 and M2 = K2, the network device determines that the antenna configuration of the terminal device is Configuration 1. Another example, if M1 = K5 and M2 = K6, the network device determines that the antenna configuration of the terminal device is Configuration 3.

[0092] Method 2: The first indication information is used to indicate whether the transmit antennas of the terminal device for transmitting signals on the first uplink carrier and the second uplink carrier are shared.

[0093] For this Method 2, it is divided into the following two cases:

[0094] Case 1: The first indication information indicates that the transmit antennas of the terminal device for transmitting signals on the first uplink carrier and the second uplink carrier are shared.

[0095] For this Case 1, since the transmit antennas of the terminal device for transmitting signals on the first uplink carrier and the second uplink carrier are shared, the network device can determine that the antenna configuration of the terminal device should belong to Configuration 2 above.

[0096] Case 2: The first indication information indicates that the transmit antennas of the terminal device for transmitting signals on the first uplink carrier and the second uplink carrier are not shared.

[0097] For this case 2, since the transmission antennas for the terminal device to send signals on the first uplink carrier and the second uplink carrier are not shared, the network device can determine that the antenna configuration of the terminal device should belong to the above configuration 1 or configuration 3.

[0098] Furthermore, the network device can determine that the antenna configuration of the terminal device is configuration 1 or configuration 3 according to the first maximum number of transmission antennas M1 supported by the terminal device when sending signals only on the first uplink carrier and the second maximum number of transmission antennas M2 supported by the terminal device when sending signals only on the second uplink carrier. For example, if M1 = K1 and M2 = K2, the network device determines that the antenna configuration of the terminal device is configuration 1. For another example, if M1 = K5 and M2 = K6, the network device determines that the antenna configuration of the terminal device is configuration 3.

[0099] For case 1 of the above method 1 or case 1 of method 2, as an implementation method, the switching time when the terminal device switches between the first uplink carrier and the second uplink carrier is equal to t1, and t1 is greater than 0. For example, when the first uplink carrier and the second uplink carrier come from different cell groups and the cell groups correspond to different radio access technologies, this switching time t1 is used for the terminal device to convert the shared antenna from LTE uplink to NR uplink, or for the terminal device to convert the shared antenna from NR uplink to LTE uplink. This switching time t1 can be reported by the terminal device to the network device, or can be predefined by the protocol. For example, when the switching time t1 includes one or more values, it can be reported by the terminal device to the network device. For example, this switching time t1 can be one or more of 35 us, 120 us, etc. For another example, when the switching time t1 has only one value, it can be without the need for the terminal device to report. In this solution, regardless of how many transmission antennas the terminal device actually uses on the first uplink carrier and how many transmission antennas the terminal device actually uses on the second uplink carrier, the switching is performed according to the same switching time t1.

[0100] For case 1 of the above method 1 or case 1 of method 2, as another implementation method, when the terminal device switches between transmitting signals using N1 transmitting antennas on the first uplink carrier and using N2 transmitting antennas on the second uplink carrier, the switching time is equal to t1, where t1 > 0. Here, N1 + N2 > M, N1 <= K3, and N2 <= K4. And / or, when the terminal device switches between transmitting signals using N3 transmitting antennas on the first uplink carrier and using N4 transmitting antennas on the second uplink carrier, the switching time is equal to t2, where t2 >= 0, N3 + N4 <= M, N3 <= K3, and N3 <= K4. The description of the switching time t1 refers to the previous description, and the switching time t2 can be equal to 0 or close to 0. In this solution, when the sum of the number of transmitting antennas N1 actually used by the terminal device on the first uplink carrier and the number of transmitting antennas N2 actually used on the second uplink carrier is greater than M, the switching time is t1, that is, the transmitting antennas cannot satisfy both NR transmission and LTE transmission simultaneously, so a switch is required. When the sum of the number of transmitting antennas N3 actually used by the terminal device on the first uplink carrier and the number of transmitting antennas N4 actually used on the second uplink carrier is less than or equal to M, the switching time is t2, that is, the transmitting antennas can satisfy both NR transmission and LTE transmission simultaneously, so no switch is required.

[0101] For case 2 of the above method 1 or case 2 of method 2, when the terminal device switches between the first uplink carrier and the second uplink carrier, the switching time is equal to t2. The switching time t2 can be equal to 0 or close to 0. In this solution, since there is no shared transmitting antenna between the transmitting antennas for the terminal device to transmit signals on the first uplink carrier and the second uplink carrier, the switching time is t2, that is, no switch is required.

[0102] Method 3: The first indication information is used to indicate the switching time between the transmitting antennas for the terminal device to transmit signals on the first uplink carrier and the second uplink carrier.

[0103] For this method 3, it is divided into the following two cases:

[0104] Case 1: The switching time indicated by the first indication information between the transmitting antennas for the terminal device to transmit signals on the first uplink carrier and the second uplink carrier is equal to t1, where t1 > 0.

[0105] For this case 1, since the switching time is equal to t1, it indicates that the transmitting antennas for the terminal device to transmit signals on the first uplink carrier and the second uplink carrier are shared. Therefore, the network device can determine that the antenna configuration of the terminal device should belong to the above configuration 2.

[0106] Case 2, the switching time between the transmission antennas of the terminal device for transmitting signals on the first uplink carrier and the second uplink carrier indicated by the first indication information is equal to t2, and t2 is equal to 0 or close to 0.

[0107] For this Case 2, since the switching time is equal to t2, it indicates that the transmission antennas for transmitting signals on the first uplink carrier and the second uplink carrier of the terminal device are not shared. Therefore, the network device can determine that the antenna configuration of the terminal device should belong to the above Configuration 1 or Configuration 3.

[0108] Furthermore, the network device can determine the antenna configuration of the terminal device as Configuration 1 or Configuration 3 according to the first maximum number of transmission antennas M1 supported by the terminal device when transmitting signals only on the first uplink carrier and the second maximum number of transmission antennas M2 supported by the terminal device when transmitting signals only on the second uplink carrier. For example, if M1 = K1 and M2 = K2, then the network device determines that the antenna configuration of the terminal device is Configuration 1. Another example, if M1 = K5 and M2 = K6, then the network device determines that the antenna configuration of the terminal device is Configuration 3.

[0109] Method 4, the first indication information is used to indicate the type of antenna configuration of the terminal device.

[0110] For example, 2 bits can be used to indicate three types of antenna configurations. As an example, 00 is used to indicate the above Configuration 1, 01 is used to indicate the above Configuration 2, and 10 is used to indicate the above Configuration 3.

[0111] For the above Methods 1 to 4, as an implementation method, the first message in step 301 further includes second indication information, and the second indication information is used to indicate the number of shared transmission antennas X between the transmission antennas of the terminal device for transmitting signals on the first uplink carrier and the transmission antennas for transmitting signals on the second uplink carrier.

[0112] It should be noted that the above solutions in this application are not limited to antenna sharing between different carriers, and can also be applied to antenna sharing between different frequency bands.

[0113] It should be noted that when the terminal device reports the first maximum number of antennas M1 supported by the terminal device when transmitting signals only on the first uplink carrier to the network device, the indication information reported by the existing terminal device can also be reused. Here, the first uplink carrier refers to the uplink carrier in NR.

[0114] For example, in the prior art, the supportedSRS-TxPortSwitch field in the SRS-TxSwitch unit directly indicates the SRS antenna switching capability of the terminal device, such as 1 transmit and 4 receive (1 transmit antenna and 4 receive antennas), 2 transmit and 4 receive, etc., thereby indirectly indicating that the first maximum number of antennas M1 supported by the terminal device when transmitting signals only on the first uplink carrier is equal to the number of transmit antennas in the sounding reference signal (SRS) antenna switching capability.

[0115] For another example, in the prior art, the MIMO-Layers field directly indicates the maximum number of spatial layers for the terminal device to transmit uplink signals, such as one of 1 layer, 2 layers, and 4 layers, thereby indirectly indicating that the first maximum number of antennas M1 supported by the terminal device when transmitting signals only on the first uplink carrier is equal to the maximum number of spatial layers.

[0116] For another example, in the prior art, the maxNumberSRS-Ports-PerResource field directly indicates the maximum number of SRS ports in an SRS resource, which can be one of 1, 2, and 4, thereby indirectly indicating that the first maximum number of antennas M1 supported by the terminal device when transmitting signals only on the first uplink carrier is equal to the maximum number of SRS ports in an SRS resource.

[0117] The above mainly introduces the solution provided by this application from the perspective of the interaction between each network element.

[0120] The device 400 can be the terminal device or the network device in any of the above embodiments, and can also be a chip for the terminal device or the network device. For example, when the device 400 is the terminal device or the network device, the processing unit 402 can be a processor, and the communication unit 401 can be a transceiver. Optionally, the transceiver can include a radio frequency circuit. For example, when the device 400 is a chip for the terminal device or the network device, the processing unit 402 can be a processor, and the communication unit 401 can be an input / output interface, a pin, a circuit, etc. The processing unit 402 can execute the computer-executable instructions stored in the storage unit.

[0121] In the first embodiment, the device 400 is a terminal device. The processing unit 402 is configured to generate a first message, where the first message includes first indication information, and the first indication information is used to indicate the maximum number of transmit antennas M that the terminal device supports in total when simultaneously transmitting signals on at least two uplink carriers, or is used to indicate whether the transmit antennas for the terminal device to transmit signals on at least two uplink carriers share; and the communication unit 401 is configured to send the first message to a network device.

[0123] In a possible implementation method, the processing unit 402 is further configured to determine the maximum number of transmit antennas that the terminal device supports in total according to the first indication information.

[0124] Based on the above first embodiment or the above second embodiment:

[0125] In a possible implementation method, the at least two uplink carriers include a first uplink carrier and a second uplink carrier. When the first indication information is used to indicate the maximum number of transmit antennas that the terminal device supports in total when simultaneously transmitting signals on the first uplink carrier and the second uplink carrier, if the maximum number of transmit antennas indicated by the first indication information is less than the sum of the first maximum number of transmit antennas that the terminal device supports when only transmitting signals on the first uplink carrier and the second maximum number of transmit antennas that the terminal device supports when only transmitting signals on the second uplink carrier, then the handover time when the terminal device handovers between the first uplink carrier and the second uplink carrier is equal to t1, and t1 is greater than 0.

[0126] Based on this solution, by setting a handover time, some antennas of the terminal device can be shared, that is, the shared transmit antennas can be used for transmitting signals of the first uplink carrier or for transmitting signals of the second uplink carrier through the handover time, which is beneficial to improving the utilization efficiency of the transmit antennas, and further improves the communication efficiency between the terminal device and the network device.

[0127] In a possible implementation method, among the at least two uplink carriers, there are a first uplink carrier and a second uplink carrier. When the first indication information is used to indicate the maximum number of transmit antennas that the terminal device supports in total when transmitting signals on the first uplink carrier and the second uplink carrier simultaneously, if the maximum number of transmit antennas indicated by the first indication information is less than the sum of the first maximum number of antennas that the terminal device supports when transmitting signals only on the first uplink carrier and the second maximum number of antennas that the terminal device supports when transmitting signals only on the second uplink carrier,

[0128] the switching time when the terminal device switches between transmitting signals using N1 transmit antennas on the first uplink carrier and transmitting signals using N2 transmit antennas on the second uplink carrier is equal to t1, where N1 + N2 is greater than the maximum number of transmit antennas indicated by the first indication information, and t1 is greater than 0; and / or,

[0129] the switching time when the terminal device switches between transmitting signals using N3 transmit antennas on the first uplink carrier and transmitting signals using N4 transmit antennas on the second uplink carrier is equal to t2, where N3 + N4 is less than or equal to the maximum number of transmit antennas indicated by the first indication information, and t2 is greater than or equal to 0.

[0130] In a possible implementation method, among the at least two uplink carriers, there are a first uplink carrier and a second uplink carrier. When the first indication information is used to indicate the maximum number of transmit antennas that the terminal device supports in total when transmitting signals on the first uplink carrier and the second uplink carrier simultaneously, if the maximum number of transmit antennas indicated by the first indication information is equal to the sum of the first maximum number of antennas that the terminal device supports when transmitting signals only on the first uplink carrier and the second maximum number of antennas that the terminal device supports when transmitting signals only on the second uplink carrier, then the switching time when the terminal device switches between the first uplink carrier and the second uplink carrier is equal to t2, and t2 is greater than or equal to 0.

[0131] In a possible implementation method, among the at least two uplink carriers, there are a first uplink carrier and a second uplink carrier. When the first indication information is used to indicate whether the transmit antennas for the terminal device to transmit signals on the first uplink carrier and the second uplink carrier are shared, if the first indication information indicates that the transmit antennas for the terminal device to transmit signals on the first uplink carrier and the second uplink carrier are shared, then the switching time when the terminal device switches between the first uplink carrier and the second uplink carrier is equal to t1, and t1 is greater than 0.

[0132] In a possible implementation method, the at least two uplink carriers include a first uplink carrier and a second uplink carrier. When the first indication information is used to indicate whether the transmit antennas for the terminal device to send signals on the first uplink carrier and the second uplink carrier share, if the first indication information indicates that the transmit antennas for the terminal device to send signals on the first uplink carrier and the second uplink carrier share,

[0133] then the switching time when the terminal device switches between using N1 transmit antennas to send signals on the first uplink carrier and using N2 transmit antennas to send signals on the second uplink carrier is equal to t1, where t1>0, and N1 + N2>M1 + M2 - X; and / or,

[0134] the switching time when the terminal device switches between using N3 transmit antennas to send signals on the first uplink carrier and using N4 transmit antennas to send signals on the second uplink carrier is equal to t2, where t2≥0, and N3 + N4≤M1 + M2 - X;

[0135] wherein, M1 is the first maximum number of transmit antennas supported by the terminal device when sending signals only on the first uplink carrier, M2 is the second maximum number of transmit antennas supported by the terminal device when sending signals only on the second uplink carrier, and X is the number of shared transmit antennas between the transmit antennas for the terminal device to send signals on the first uplink carrier and the transmit antennas for the terminal device to send signals on the second uplink carrier.

[0136] In a possible implementation method, the at least two uplink carriers include a first uplink carrier and a second uplink carrier. When the first indication information is used to indicate whether the transmit antennas for the terminal device to send signals on the first uplink carrier and the second uplink carrier share, if the first indication information indicates that the transmit antennas for the terminal device to send signals on the first uplink carrier and the second uplink carrier do not share, then the switching time when the terminal device switches between the first uplink carrier and the second uplink carrier is equal to t2, where t2≥0.

[0137] In a possible implementation method, the first message further includes second indication information, and the second indication information is used to indicate the number of shared transmit antennas between the transmit antennas for the terminal device to send signals on the first uplink carrier and the transmit antennas for the terminal device to send signals on the second uplink carrier.
