Description

Technical Field

[0001] This disclosure relates to the field of communication technology, and more specifically, to a downlink data transmission method, apparatus, electronic device, computer-readable storage medium, and computer program product. Background Technology

[0002] Uplink Transmission Switching (ULTx Switching), introduced in the 5G communication standard, works on the principle that when a user equipment (UE) uses two carriers of different frequency bands (e.g., a combination of low-frequency and high-frequency carriers) for uplink data transmission, it alternates between the low-frequency and high-frequency carriers using Time-Division Multiplexing (TDM). This mechanism allows the system to simultaneously leverage the strong penetration capability and continuous transmission across all time slots of low-frequency signals, as well as the abundant spectrum resources and high bandwidth support of high-frequency signals. This flexible carrier scheduling method allows for more efficient utilization of uplink resources, effectively improving uplink coverage and data transmission rates. Currently, the standard does not support antenna switching during downlink transmission.

[0003] As mentioned above, how to provide an antenna switching scheme during downlink transmission has become an urgent problem to be solved.

[0058] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the examples set forth herein; rather, they are provided so that this disclosure will be more comprehensive and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The drawings are merely illustrative of this disclosure and are not necessarily drawn to scale. The same reference numerals in the drawings denote the same or similar parts, and therefore repeated descriptions of them will be omitted.

[0059] Furthermore, the described features, structures, or characteristics can be combined in any suitable manner in one or more embodiments. Numerous specific details are provided in the following description to give a thorough understanding of embodiments of this disclosure. However, those skilled in the art will recognize that the technical solutions of this disclosure can be practiced with one or more of the specific details omitted, or other methods, apparatuses, steps, etc., can be employed. In other instances, well-known structures, methods, apparatuses, implementations, or operations are not shown or described in detail to avoid obscuring various aspects of this disclosure.

[0060] Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this disclosure, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified. The symbol " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0061] In this disclosure, unless otherwise expressly specified and limited, the term "connection" and similar terms should be interpreted broadly, for example, it can refer to an electrical connection or the ability to communicate with each other; it can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this disclosure according to the specific circumstances.

[0062] The terminology used in the embodiments of this disclosure will be explained below.

[0063] Network (side) equipment: refers to equipment on the network side responsible for receiving communication requests from terminal devices, establishing communication connections with terminal devices, and completing communication between terminal devices and the network, such as base stations.

[0064] Terminal (side) devices: These are devices that establish communication connections with network devices and conduct communication, such as desktop computers, tablets, mobile phones and other communication devices, as well as IoT terminal devices such as wearable devices, virtual reality devices, and smart home devices.

[0065] Carrier: A radio wave of a specific frequency, measured in Hertz (Hz).

[0066] As mentioned above, the current standard does not support antenna switching during downlink transmission. Some frequency bands in the current standard support multi-port reception; for example, n5 and n8 support 4Rx, and n7 and n41 support 8Rx. These bands can provide higher throughput. In scenarios such as carrier aggregation and multiple connections, if one of the frequency domain resources supports a limited number of ports (e.g., 2Rx), the number of transmission layers will be limited by the limited number of supported ports in the frequency domain resource without antenna switching. Furthermore, when implementing carrier aggregation and multiple connections between some low-frequency bands defined in the 5G standard, due to insufficient spacing between some frequency bands, downlink transmission between adjacent frequency bands may fail due to interference, especially given limitations in terminal hardware implementation. In other words, the terminal cannot complete low-frequency band aggregation using conventional carrier aggregation methods.

[0067] Therefore, this disclosure provides a downlink data transmission method in which the terminal device sends capability information, including frequency domain resource information supporting downlink antenna switching, to the network-side device. This allows antenna switching to be performed during downlink data transmission according to the downlink antenna switching configuration information obtained by the network-side device based on the capability information, thereby realizing antenna switching during downlink data transmission and at least solving one of the above-mentioned problems.

[0068] Figure 1 A schematic diagram of a system architecture for which the downlink data transmission method or downlink data transmission apparatus of this disclosure can be applied is shown. For example... Figure 1As shown, network device 102 can be a base station, and network device 102 can communicate with multiple terminal devices, for example, it can communicate with K (K is a positive integer) terminal devices. The downlink data transmission method provided in this embodiment can be applied to 5G systems, 6G systems, and so on.

[0069] Figure 2 This is a flowchart illustrating a downlink data transmission method according to an exemplary embodiment. For example... Figure 2 The method shown can be applied, for example, to... Figure 1 The system shown in the example can be executed by a terminal device.

[0070] refer to Figure 2 The method 20 provided in this embodiment may include the following step S202.

[0071] In step S202, capability information is sent to the network-side device. The capability information includes frequency domain resource information that supports downlink antenna switching.

[0072] In some embodiments, the frequency domain resource information supporting downlink antenna switching may include at least one of the following: frequency domain resource combination information supporting downlink antenna switching; and the scheduling method for downlink antenna switching.

[0073] In some embodiments, frequency domain resource information may include, but is not limited to, frequency bands, carriers, and other radio resources. Taking a carrier aggregation scenario as an example, the frequency domain resource information supporting downlink antenna switching may include carrier aggregation CA_nX-nY-nZ supporting downlink antenna switching.

[0074] In some embodiments, the frequency domain resource combination information supporting downlink antenna switching indicates information about multiple frequency domain resources, and information supporting the downlink antenna switching from at least one of the multiple frequency domain resources to another frequency domain resource.

[0075] In some embodiments, the information supporting the downlink antenna to switch from at least one frequency domain resource among a plurality of frequency domain resources to another frequency domain resource includes at least one of the following: information supporting the downlink antenna to switch from one frequency domain resource among a plurality of frequency domain resources to another frequency domain resource; information supporting the downlink antenna to switch from at least two frequency domain resources among a plurality of frequency domain resources to another frequency domain resource simultaneously.

[0076] In some embodiments, information supporting the simultaneous switching of a downlink antenna from at least two frequency domain resources among a plurality of frequency domain resources to another frequency domain resource may include at least one of the following: information supporting the simultaneous switching of a downlink antenna from at least two frequency domain resources among a plurality of frequency domain resources to another frequency domain resource; information supporting the simultaneous switching of a downlink antenna from at least two frequency domain resources among a plurality of frequency domain resources to two other frequency domain resources respectively.

[0077] Taking information on multiple frequency domain resources, including information on a first frequency domain resource, a second frequency domain resource, a third frequency domain resource, and a fourth frequency domain resource, as an example, the information supporting the downlink antenna to switch from at least one frequency domain resource to another can include at least one of the following: information supporting the downlink antenna to switch from a first frequency domain resource to a second frequency domain resource, and / or, information supporting the downlink antenna to switch from a first frequency domain resource to a third frequency domain resource; information supporting the downlink antenna to switch simultaneously from a first frequency domain resource and a second frequency domain resource to a third frequency domain resource; information supporting the downlink antenna to switch simultaneously from a first frequency domain resource and a second frequency domain resource to a fourth frequency domain resource; information supporting the downlink antenna to switch simultaneously from a first frequency domain resource and a second frequency domain resource to both a third frequency domain resource and a fourth frequency domain resource.

[0078] For example, frequency domain resource combination information that supports downlink antenna switching can indicate that, for carrier aggregation CA_nX-nY-nZ-nP, the terminal device supports antenna switching between frequency bands nX and nY, nX and nZ, switching from nX and nY simultaneously to nZ, switching from nX and nY simultaneously to nZ and nP, and so on.

[0079] In some embodiments, the scheduling method for downlink antenna switching includes information on a first frequency domain resource and information on a second frequency domain resource, wherein the first frequency domain resource and the second frequency domain resource are different frequency domain resources, and at least one of the following: supporting downlink data transmission in a time-division manner on the first frequency domain resource and the second frequency domain resource; supporting downlink data transmission simultaneously on the first frequency domain resource and the second frequency domain resource. Figure 3 and Figure 4 The following is an exemplary diagram illustrating the data transmission of the first and second frequency domain resources using these two scheduling methods.

[0080] In some embodiments, the frequency domain resource combination information supporting downlink antenna switching indicates at least the number of receive channels and / or the number of supported transmission layers for downlink transmission on at least one of a plurality of frequency domain resources. For example, the number of receive channels and / or the number of supported transmission layers may be less than or equal to the number of receive antennas.

[0081] In some embodiments, antenna ports that are not involved in antenna switching can continue to receive data during the switching process.

[0082] In some embodiments, where the frequency domain resource information supporting downlink antenna switching includes a scheduling method for downlink antenna switching, and the scheduling method for downlink antenna switching includes frequency domain resource combination information supporting downlink antenna switching, the frequency domain resource combination information supporting downlink antenna switching at least indicates the time information for downlink transmission switching between the first frequency domain resource and the second frequency domain resource.

[0083] In some embodiments, the timing information for switching downlink transmission between the first frequency domain resource and the second frequency domain resource includes at least one of the following: switching is performed in the time slot corresponding to the initial switching start resource during downlink data transmission on the first frequency domain resource and the second frequency domain resource; switching is performed in the time slot corresponding to the initial switching end resource during downlink data transmission on the first frequency domain resource and the second frequency domain resource; switching is performed in the time slot corresponding to each switching start resource during downlink data transmission on the first frequency domain resource and the second frequency domain resource; and switching is performed in the time slot corresponding to each switching end resource during downlink data transmission on the first frequency domain resource and the second frequency domain resource. Figures 5 to 8 These exemplary implementations illustrate several ways to switch resource slots located in different frequency domains.

[0084] In some embodiments, the timing information for switching downlink transmission between a first frequency domain resource and a second frequency domain resource includes one or more time slot information. Figures 5 to 8 For example, the time slots s1, s2, s3, and s4 shown can each include one or more time slots.

[0085] In some embodiments, after receiving capability information sent by the terminal device, the network-side device can obtain corresponding configuration information based on the capability information. Exemplary implementations can be found in [reference needed]. Figure 9 .

[0086] According to the downlink data transmission method provided in this disclosure, the terminal device sends capability information including frequency domain resource information supporting downlink antenna switching to the network-side device. The network-side device can configure downlink antenna switching according to the capability information, thereby performing antenna switching in downlink data transmission according to the downlink antenna switching configuration information, thus realizing antenna switching in downlink data transmission.

[0087] In some frequency bands that support multi-port reception, such as n5 and n8 bands which support 4-port reception (4Rx) and n7 and n41 which support 8Rx, the method provided in this disclosure can be used to preferentially utilize these frequency bands in carrier aggregation and multiple connections. This can improve coverage through diversity and increase capacity through multiplexing, i.e., by increasing or decreasing the number of transmission layers through antenna switching, thereby improving throughput or reliability. For example, in the carrier aggregation CA_nX-n41 scenario, frequency band nX only supports 2-port transmission, and n41 supports a maximum of 4Rx. Without antenna switching, the maximum number of transmission layers is 2+4=6. If the method provided in this disclosure is used to perform antenna switching, the maximum number of transmission layers becomes 4+4=8.

[0088] In carrier aggregation transmission between some low-frequency bands, the frequency bands of the carriers used for uplink transmission and the carriers used for downlink transmission in some low-frequency bands are too close together, which cannot be achieved under the current CA mechanism. For example, in CA_n12A-n29A, n12 includes both uplink and downlink time slots, while n29 only has a downlink time slot. When frequency band 12 is in uplink mode, frequency band 29 is interfered with due to the close frequency bands and therefore cannot perform downlink data transmission. Using the method provided in the embodiments of this disclosure, the downlink transmission currently performed through n29 can be switched to downlink transmission through n12, effectively avoiding interference.

[0089] Figure 3 and Figure 4 Examples illustrate the first frequency domain resources (i.e., the resources corresponding to the two scheduling methods) Figure 3 and Figure 4 (i.e., resources in the first and second frequency domains) Figure 3 and Figure 4 A schematic diagram of data transmission in Resource II. Figure 3 and Figure 4 In the text, "D" represents the downlink time slot, "U" represents the uplink time slot, and "S" represents the special time slot.

[0090] Figure 3 A schematic diagram of frequency domain resources in a scheduling method is shown according to an exemplary embodiment. Figure 3 This illustrates an example of downlink data transmission using a time-division multiplexing method across different resources. For example... Figure 3As shown, at the beginning of time period T1, the system switches from resource one to resource two, and data transmission occurs in the downlink time slot D of resource two within time period T1; at the end of time period T1, the system switches from resource two to resource one, and data transmission occurs in the special time slot S and uplink time slot U of resource one within time period T2; at the end of time period T2 and / or the beginning of time period T3, the system switches from resource one to resource two, and data transmission occurs in the downlink time slot D of resource two within time period T3; at the end of time period T3, the system switches from resource two to resource one, and data transmission occurs in the special time slot S and uplink time slot U of resource one within time period T4.

[0091] Figure 4 A schematic diagram of frequency domain resources in another scheduling method is shown according to an exemplary embodiment. Figure 3 An example of simultaneous data transfer across different resources is shown. Figure 3 As shown, data transmission occurs in all time slots of Resource 1 and Resource 2 within time period T.

[0092] Figures 5 to 8 Shown in the first frequency domain resources (i.e. Figures 5 to 8 (i.e., resources in the first and second frequency domains) Figures 5 to 8 This diagram illustrates several scenarios regarding the timing of resource switching when there is a periodic switching between resources (resource 2).

[0093] Figure 5 An exemplary implementation of a frequency domain resource where a time slot for switching resources is located is shown. Figure 5 In the case of periodic switching between resource one and resource two, the switching occurs at the time slot s1 corresponding to the initial switching starting resource, i.e., resource one.

[0094] Figure 6 Another exemplary implementation of the frequency domain resources where the time slots used for switching resources are located is shown. Figure 6 In the case of periodic switching between resource one and resource two, the switching occurs in time slot s2 corresponding to the initial switching endpoint resource, i.e., resource two.

[0095] Figure 7 Another exemplary implementation of the frequency domain resources where the time slots for switching resources are located is shown. Figure 7 In the case of periodic switching between resource one and resource two, the switching occurs in time slot s3 corresponding to the resource at the start of each switching. For example, when switching from resource one to resource two, the switching occurs in time slot s3 at the end of resource one; when switching from resource two to resource one, the switching occurs in time slot s3 at the end of resource two.

[0096] Figure 8 Another exemplary implementation of the frequency domain resources where the time slots for switching resources are located is shown. Figure 7 In the case of periodic switching between resource one and resource two, the switching occurs in time slot s4 corresponding to the end resource of each switch. For example, when switching from resource one to resource two, the switching occurs in time slot s4 at the beginning of resource two; when switching from resource two to resource one, the switching occurs in time slot s4 at the beginning of resource one.

[0097] Figure 9 This is a flowchart illustrating another downlink data transmission method according to an exemplary embodiment. For example... Figure 9 The method shown can be applied, for example, to... Figure 1 The system shown in the example can be executed by a terminal device.

[0098] Figure 9 and Figure 2 The connection is that, Figure 9 The method can be found in Figure 2 Then execute. (See reference) Figure 9 The method 90 provided in this embodiment may include the following step S902.

[0099] In step S902, downlink antenna switching configuration information sent by the network-side device is received, so as to perform antenna switching in downlink data transmission according to the downlink antenna switching configuration information.

[0100] In some embodiments, after receiving capability information sent by the terminal device, the network-side device can obtain corresponding configuration information based on the capability information.

[0101] Taking the capability information including information on carrier aggregation CA_n12A-n29A, indicating that the terminal device supports antenna switching between frequency bands n12A-n29A, and supporting downlink data transmission in a time-division manner on both the first and second frequency domain resources, as an example, the network-side device can, according to the actual situation of the device, use n12A as resource one and n29A as resource two, and proceed accordingly. Figure 3 The scheduling method shown generates corresponding downlink antenna switching configuration information and sends it to the terminal device so that the terminal device can configure accordingly and perform antenna switching in downlink data transmission.

[0102] According to the downlink data transmission method provided in this disclosure, after the terminal device sends capability information including frequency domain resource information supporting downlink antenna switching to the network-side device, it receives downlink antenna switching configuration information obtained from the capability information sent by the network-side device. Thus, antenna switching can be performed in downlink data transmission according to the downlink antenna switching configuration information, thereby realizing antenna switching in downlink data transmission.

[0103] Figure 10This is a flowchart illustrating a data processing method according to an exemplary embodiment. For example... Figure 10 The method shown can be applied, for example, to... Figure 1 The system shown in the example can be executed by a terminal device.

[0104] Figure 10 and Figure 2 and Figure 9 The connection lies in the fact that the terminal executes... Figure 10 ,activation Figure 2 Then execute Figure 9 Configuration for downlink antenna switching. (Refer to...) Figure 10 The method 100 provided in this embodiment may include the following step S1002.

[0105] In step S1002, a first activation information sent by a network-side device is received, the first activation information indicating that switching between different resources is performed periodically during downlink data transmission.

[0106] In some embodiments, Figure 2 and Figure 9 The antenna switching scheme in the system can be semi-static, that is, in Figure 2 and Figure 9 Once the method in the diagram is completed, meaning both the network-side device and the terminal device have completed the downlink transmission antenna switching configuration, antenna switching does not need to be performed immediately. Instead, after the network-side device decides to proceed with downlink transmission according to the completed configuration, an activation message is sent to the terminal device at the Medium Access Control Layer (MAC). After the terminal device receives and activates the message, downlink data transmission between the network-side device and the terminal device switches periodically between Resource 1 and Resource 2.

[0110] In step S1104, antenna switching is performed in downlink data transmission according to the downlink antenna switching configuration information at the time corresponding to the delay information.

[0111] In some embodiments, Figure 2 and Figure 9 Once the method in the diagram is completed, meaning both the network-side device and the terminal device have completed the downlink transmission antenna switching configuration, antenna switching does not need to be performed immediately. Instead, after the network-side device decides to proceed with downlink transmission according to the completed configuration, a timer can be set and a delay information can be sent to the terminal device. For example, the delay information can be 10 seconds. After receiving the delay information, the terminal device will delay for 10 seconds and then switch antennas according to the configuration.

Figure 12 The method 120 provided in this embodiment may include the following step S1202.

[0114] In step S1202, a second activation information sent by the network-side device is received. The second activation information indicates that antenna switching is performed in downlink data transmission according to the downlink antenna switching configuration information.

[0115] In some embodiments, Figure 2 and Figure 9 Once the method in the diagram is completed, meaning that both the network-side device and the terminal device have completed the downlink transmission antenna switching configuration, antenna switching can be delayed. Instead, after the network-side device decides to proceed with downlink transmission according to the completed configuration, a second activation message can be sent to the terminal device via Downlink Control Information (DCI) to activate the corresponding antenna switching configuration.
