Description

A data processing method and corresponding apparatus

[0001] This application claims priority to Chinese Patent Application No. 202410925130.X, filed on July 10, 2024, entitled “A Data Processing Method and Corresponding Apparatus”, the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of communication technology, specifically to a data processing method and corresponding apparatus. Background Technology

[0003] With the increasing demand for spectrum resources in the field of wireless communication, more frequencies are being used for wireless communication, such as U6G, centimeter wave, and millimeter wave frequencies. As a result, a single active antenna unit (AAU) or remote radio unit (RRU) system needs to integrate more frequency bands, each with its own unique radio frequency channel resources, thus forming a multi-frequency communication system.

[0004] However, when the system operates in time division duplex (TDD) mode, it processes data reception and transmission in different time slots. Specifically, when the frequency is in the downlink time slot, the system's receive channel is idle, while when the frequency switches to the uplink time slot, the system's transmit channel is idle. Therefore, improving the utilization rate of RF channels in multi-frequency TDD systems has become an urgent problem to be solved. Summary of the Invention

[0005] This application provides a data processing method and corresponding apparatus for reusing radio frequency (RF) channels in a multi-frequency TDD system, thereby improving RF channel utilization and reducing the hardware resource requirements of RF channels. This application also provides corresponding apparatus, computer-readable storage media, and computer program products.

[0006] In a first aspect, embodiments of this application provide a data processing method applied to a time-division duplex (TDD) system with multiple frequencies, the method comprising:

[0007] The first communication device determines a target transceiver mode based on the time slot allocation relationship of each frequency among multiple frequencies. The first communication device includes multiple radio frequency channels, and the target transceiver mode is used to indicate the on / off state of the multiple radio frequency channels in multiple time units. The first radio frequency channel is used to transmit data at at least two frequencies. The first radio frequency channel is one of the multiple radio frequency channels, and the at least two frequencies are frequencies among the multiple frequencies.

[0008] The first communication device receives or sends data according to the target transmit / receive mode.

[0009] In this application, the first communication device may be an access network device, a terminal device, or a chip in the access network device or a chip in the terminal device.

[0010] TDD is a duplex mode in communication systems that uses different time slots on the same frequency channel to separate the receive and transmit channels (or uplink and downlink) using time. Uplink transmission (signals sent from the terminal device to the access network device) and downlink transmission (signals sent from the access device to the terminal device) are allocated to different time slots. The frequency-time slot allocation ratio indicates the ratio between the time slots used for uplink transmission and those used for downlink transmission. In general, the target transmit / receive mode is an indication mechanism that guides the radio frequency channel within the first communication device to perform corresponding receive and transmit operations according to the time sequence of predetermined time domain resources.

[0011] It should be noted that the frequency slot allocation in a TDD system varies depending on the communication scenario. For example, in scenarios with high downlink transmission demands, such as streaming media services and file downloads, the proportion of downlink slots is usually higher. Typically, the ratio of downlink to uplink slots is "4:1", meaning that out of five consecutive slots, four are used for downlink data transmission and one for uplink data transmission; or the ratio may be "8:2" or "7:3", etc., without specific limitations.

[0012] The target transceiver mode in this application involves staggering the uplink (or downlink) time slots (or downlink time slots) of multiple frequencies in the time domain. Using this scheme, the uplink (or downlink) only requires one receive channel (or transmit channel) to perform signal reception (or signal transmission) at any given time point, thereby achieving time-division multiplexing of RF channels across multiple frequencies, reducing the hardware resource requirements of RF channels, and lowering the hardware complexity of the system.

[0013] In one possible implementation, the multiple radio frequency channels include a receiving channel and a transmitting channel, and the first time slot allocation relationship of the target frequency is the ratio between the first time slot and the second time slot; wherein, the receiving channel is used to receive data transmitted at the target frequency in the first time slot, and the transmitting channel is used to transmit data transmitted at the target frequency in the second time slot, and the target frequency is one of multiple frequencies.

[0014] In one possible implementation, if the first radio frequency channel is a receiving channel, the target transceiver mode includes a first allocation result, which is used to instruct the first radio frequency channel to receive first data in a first time unit and to receive second data in a second time unit, wherein the first data and the second data belong to data in different frequencies among at least two frequencies, and the first time unit and the second time unit are different time units.

[0015] In one possible implementation, if the first radio frequency channel is a transmit channel, the target transmit / receive mode includes a second allocation result, which is used to instruct the first radio frequency channel to transmit third data in a third time unit and fourth data in a fourth time unit, wherein the third data and the fourth data belong to data in different frequencies among at least two frequencies, and the third time unit and the fourth time unit are different time units.

[0016] In one possible implementation, at least two frequencies include a first frequency and a second frequency, wherein the starting subframe of the first frequency and the starting subframe of the second frequency are not in the same time unit.

[0017] In this application, by adjusting the starting time point of the frequency, that is, adjusting the time unit corresponding to the starting subframe, the uplink time slots (or downlink time slots) between at least two frequencies are staggered.

[0018] In one possible implementation, the subcarrier spacing between at least two frequencies is different.

[0019] In one possible implementation, at least two frequencies include an auxiliary uplink SUL frequency.

[0020] In this application, the SUL frequency is a frequency with only uplink time slots. The uplink time slots between at least two frequencies can be staggered by adjusting some time slot states to an idle state.

[0021] Secondly, embodiments of this application provide a data processing apparatus applied in a time-division duplex (TDD) system with multiple frequencies, wherein the apparatus is a first communication device. The apparatus includes:

[0022] The processing module is used to determine the target transceiver mode according to the time slot allocation relationship of each frequency among multiple frequencies. The first communication device includes multiple radio frequency channels, and the target transceiver mode is used to indicate the on / off state of the multiple radio frequency channels in multiple time units. The first radio frequency channel is used to transmit data at least two frequencies. The first radio frequency channel is one of the multiple radio frequency channels, and the at least two frequencies are frequencies among the multiple frequencies.

[0023] The transceiver module is used to receive or send data according to the target transceiver mode.

[0024] In one possible implementation, the multiple radio frequency channels include a receiving channel and a transmitting channel, and the first time slot allocation relationship of the target frequency is the ratio between the first time slot and the second time slot; wherein, the receiving channel is used to receive data transmitted at the target frequency in the first time slot, and the transmitting channel is used to transmit data transmitted at the target frequency in the second time slot, and the target frequency is one of multiple frequencies.

[0025] In one possible implementation, if the first radio frequency channel is a receiving channel, the target transceiver mode includes a first allocation result, which is used to instruct the first radio frequency channel to receive first data in a first time unit and to receive second data in a second time unit, wherein the first data and the second data belong to data in different frequencies among at least two frequencies, and the first time unit and the second time unit are different time units.

[0026] In one possible implementation, if the first radio frequency channel is a transmit channel, the target transmit / receive mode includes a second allocation result, which is used to instruct the first radio frequency channel to transmit third data in a third time unit and fourth data in a fourth time unit, wherein the third data and the fourth data belong to data in different frequencies among at least two frequencies, and the third time unit and the fourth time unit are different time units.

[0027] In one possible implementation, at least two frequencies include a first frequency and a second frequency, wherein the starting subframe of the first frequency and the starting subframe of the second frequency are not in the same time unit.

[0028] In one possible implementation, the subcarrier spacing between at least two frequencies is different.

[0029] In one possible implementation, at least two frequencies include an auxiliary uplink SUL frequency.

[0055] Please refer to Figure 1. The system architecture on which the data processing method in this embodiment is based will be briefly described below.

[0056] As shown in Figure 1, network device 1, network device 2, terminal device 1, terminal device 2, terminal device 3, terminal device 4, terminal device 5, terminal device 6, terminal device 7, and terminal device 8 constitute a communication system. In this system, network device 1 can send information to one or more of terminal devices 1 through 6.

Furthermore, terminal devices 4, 5, and 6 can also form a communication system, in which terminal device 4 can send information to terminal device 5 or terminal device 6. Network device 2, terminal device 7, and terminal device 8 can also form a communication system, in which network device 2 can send information to one or more of terminal devices 7 and 8.

[0057] The terminal equipment and access network equipment of this application are described below.

[0058] The terminal device can be a wireless terminal device capable of receiving scheduling and instruction information from access network devices. The wireless terminal device can be a device that provides voice and / or data connectivity to the user, a handheld device with wireless connectivity, another processing device connected to a wireless modem, or a device with sensing capabilities.

[0059] Terminal equipment, also known as user equipment (UE), mobile station (MS), or mobile terminal (MT), is a device that includes wireless communication and / or sensing functions (providing voice or data connectivity to the user). Examples include handheld devices with wireless connectivity or in-vehicle devices. Currently, some examples of terminal equipment include: mobile phones, tablets, laptops, PDAs, drones, mobile internet devices (MIDs), wearable devices, virtual reality (VR) devices, augmented reality (AR) devices, wireless terminals in industrial control, wireless terminals in vehicle-to-everything (V2X) communication, wireless terminals in self-driving cars, wireless terminals in remote medical surgery, wireless terminals in smart grids, wireless terminals in transportation safety, wireless terminals in smart cities, and wireless terminals in smart homes. For example, wireless terminals in the Internet of Vehicles (IoV) can be in-vehicle equipment, vehicle-mounted equipment, in-vehicle modules, and vehicles themselves. Wireless terminals in industrial control can be cameras, robots, etc. Wireless terminals in smart homes can be televisions, air conditioners, robot vacuums, speakers, set-top boxes, etc.

[0060] Access network equipment is a device deployed in a radio access network (RAN) that provides wireless communication and / or sensing functions to terminal devices. For example, an access network device can be a RAN node that connects terminal devices to a wireless network. Access network equipment can also be a device deployed in a RAN that can communicate with other access network devices and provide wireless communication and / or sensing functions between access network devices.

[0061] Access network equipment includes, but is not limited to: evolved Node B (eNB), radio network controller (RNC), Node B (NB), base station controller (BSC), base transceiver station (BTS), home base station (e.g., home evolved Node B, or home Node B, HNB), baseband unit (BBU), access point (AP), wireless relay node, wireless backhaul node, transmission point (TP), or transmission and reception point (TRP) in wireless fidelity (WIFI) systems, and can also be access network equipment in 5G mobile communication systems. For example, a next-generation NodeB (gNB), transmission reception point (TRP), or transmission point (TP) in a new radio (NR) system; or one or a group of antenna panels (including multiple antenna panels) of a base station in a 5G mobile communication system; or, access network equipment can also be network nodes constituting a gNB or transmission point. For example, a baseband unit (BBU) or a distributed unit (DU), etc.

[0062] In some deployments, a gNB may include a centralized unit (CU) and a dedicated unit (DU). The gNB may also include an active antenna unit (AAU). The CU implements some of the gNB's functions, and the DU implements others. For example, the CU handles non-real-time protocols and services, implementing radio resource control (RRC) and packet data convergence protocol (PDCP) layer functions. The DU handles physical layer protocols and real-time services, implementing radio link control (RLC), media access control (MAC), and physical (PHY) layer functions. The AAU implements some physical layer processing functions, radio frequency processing, and active antenna-related functions. Information from the RRC layer ultimately becomes information from the PHY layer, or is derived from PHY layer information. Therefore, in this architecture, higher-layer signaling (such as RRC layer signaling) can be considered to be sent by the DU, or by both the DU and AAU. It is understood that access network equipment can be one or more of the following: CU nodes, DU nodes, and AAU nodes. In addition, the CU can be classified as an access network device in the radio access network (RAN) or as an access network device in the core network (CN), and this application does not limit this.

[0063] For ease of understanding, the technical terms involved in the embodiments of this application are briefly introduced below:

[0064] (1) Radio Frequency (RF) Channel: The RF channel is connected to the antenna array of the communication device through a feed network. It typically consists of a series of signal distributors, mixers, power amplifiers (PA), and low noise amplifiers (LNA). RF channel resources include: digital-to-analog conversion (DAC), analog-to-digital conversion (ADC), digital intermediate frequency processing modules, baseband processing modules, etc. The types of RF channels include: a transmitting channel, which up-converts the baseband signal to an RF signal and transmits it into space via an antenna; and a receiving channel, which down-converts the RF signal received by the antenna to a baseband signal for digital processing.

[0065] (2) Subcarrier spacing (SCS): The width of a subcarrier. In an OFDM system, a carrier with a certain bandwidth is divided into subcarriers, which are radio waves used to transmit signals. The subcarrier spacing is usually 15 kHz, or a multiple of 15 kHz, such as 30 kHz, 60 kHz, 120 kHz, etc. According to the 3rd Generation Partnership Project (3GPP) protocol, different wavelengths of electromagnetic waves correspond to different subcarrier spacings.

[0066] (3) Time slot allocation relationship of time division duplex (TDD):

[0067] TDD is a duplex mode in communication systems that uses different time slots on the same frequency channel (i.e., carrier) to separate the receive and transmit channels (or uplink and downlink) using time. Specifically, uplink (transmission from terminal device to network device) and downlink (transmission from network device to terminal device) information transmission are achieved through time division on the same carrier.

[0068] In a TDD system, a time slot is the basic unit of time for data transmission. Uplink and downlink transmissions are allocated to different time slots to ensure that uplink and downlink signals do not conflict on the same frequency. To address different service requirements, the ratio of uplink to downlink time slots in the system is typically adjusted by changing the time slot allocation. Specifically, for scenarios with higher downlink transmission demand, the proportion of downlink time slots is increased; similarly, for scenarios with higher uplink transmission demand, the proportion of uplink time slots is increased.

[0069] The size of the subcarrier spacing corresponding to the frequency directly affects the length of the time slot. Specifically, a smaller subcarrier spacing results in a longer symbol length, which may increase the length of the time slot. Conversely, a larger subcarrier spacing results in a shorter symbol length, which may decrease the length of the time slot.

[0070] Specifically, when the subcarrier spacing is 30kHz, the symbol length is 1 / 30kHz, and the length of one time slot is 0.5ms. When the subcarrier spacing is further increased to 120kHz, the length of each time slot will be shortened to 0.125ms, which is 1 / 4 of that at 30kHz.

[0071] Figure 2 shows a schematic diagram of the time slot allocation for a multi-frequency TDD system. The multi-frequency system includes Frequency 1 and Frequency 2, with a 4:1 ratio of downlink to uplink time slots for both Frequency 1 and Frequency 2. That is, out of five consecutive time slots, four are used for downlink data transmission and one for uplink data transmission. Here, D represents the downlink time slot, S represents the TDD switch time slot, and U represents the uplink time slot. In the multi-frequency system, when a frequency is in a downlink time slot, uplink resources are idle; conversely, when a frequency is in an uplink time slot, downlink resources are idle.

[0072] It should be noted that each time slot includes multiple Orthogonal Frequency Division Multiplexing (OFDM) symbols. In the S-slot, the OFDM symbols can be categorized by their function: downlink symbols (belonging to the downlink), guard interval symbols (which are temporarily suspended), and uplink symbols (belonging to the uplink). These symbols connect the D-slot and the U-slot. The guard interval symbol is a time interval set to ensure that signals do not interfere with each other during uplink / downlink transitions. The S-slot is not entirely equivalent to a complete uplink or downlink time slot, but it can be considered as a downlink time slot.

[0073] Correspondingly, for multi-band, multi-channel AAU or RRU systems, each frequency band has its own independent channel resources. As shown in the first communication device in Figure 2, when frequency 1 is in the downlink time slot, it uses transmit channel 1 to transmit signals; that is, the mixer of frequency 1 is connected to the upper channel in the TDD switching switch. When frequency 1 is in the uplink time slot, it uses receive channel 1 to receive signals; that is, the mixer of frequency 1 is connected to the lower channel in the TDD switching switch. Similarly, the transmission and reception operations of frequency 2 are handled independently by transmit channel 2 and receive channel 2, respectively. However, the applicant's research found that this independent channel scheme in multi-frequency systems leads to significant underutilization of channel resources during actual uplink and downlink time-division multiplexing, resulting in resource waste.

[0074] The application scenarios of this application have been introduced above. The following describes a data processing method provided by an embodiment of this application, in conjunction with the first communication device. This method is applied to a TDD system with multiple frequencies.

[0075] In this application, the first communication device may be an access network device, a terminal device, or a chip in the access network device or a chip in the terminal device. The first communication device integrates multiple baseband resources of different frequencies. Next, taking an example where the first communication device is an access network device capable of using two frequencies simultaneously, the data processing method provided in this application embodiment will be described. These two frequencies are identified as "Frequency 1" and "Frequency 2," respectively.

[0076] As shown in Figure 3, the data processing method provided in this application embodiment includes:

[0077] 301. The first communication device determines the target transmission and reception mode based on the time slot allocation relationship of each frequency among multiple frequencies.

[0078] In this application, the first communication device includes multiple radio frequency (RF) channels, and the target transceiver mode is used to indicate the on / off state of the multiple RF channels in multiple time units; wherein, the first RF channel is used to transmit data at two frequencies, and the first RF channel is one of the multiple RF channels. In general, the target transceiver mode is an indication mechanism that guides the RF channels within the first communication device to perform corresponding receiving and transmitting operations according to the time sequence of predetermined time domain resources.

[0079] Specifically, the frequency slot allocation in a TDD system varies depending on the communication scenario. For example, in scenarios with high downlink transmission demands, such as streaming media services and file downloads, the proportion of downlink slots is usually higher, typically with a ratio of "4:1", "8:2", or "7:3" between downlink and uplink slots.

[0080] This application provides two implementation methods for determining the aforementioned target transmission and reception mode, which are described in detail below:

[0081] (1) Adjust the starting time of the frequency.

[0082] For example, taking a communication scenario with high downlink transmission demand, the downlink time slot to uplink time slot ratio of both frequency 1 and frequency 2 is 4:1, and the subcarrier spacing of both frequency 1 and frequency 2 is the same, 30kHz.

[0083] Please refer to Figure 4, which is a schematic diagram of uplink time slot staggering in a multi-frequency TDD system with the same subcarrier spacing. Specifically, the start time of frequency 2 is delayed by one time slot duration. Optionally, if the time slot ratio of downlink to uplink time slots for both frequencies is 4:1, the start time of frequency 2 can also be delayed by two or three time slot durations; the specific delay is not limited here.

[0084] Correspondingly, as shown in Figure 4, within the same time domain resources, frequencies 1 and 2 may simultaneously be in downlink time slots. Therefore, to ensure smooth signal transmission, the first communication device configures independent transmission channels for frequencies 1 and 2, namely transmission channel 1 and transmission channel 2, respectively. Since the uplink time slots of frequencies 1 and 2 are staggered, switching between frequencies 1 and 2 can be achieved on demand simply by adjusting the frequency selection switch of receiving channel 1 in Figure 4.

[0085] Specifically, when frequency 1 is the uplink time slot (U in the upper part of Figure 4), receiving channel 1 will establish a connection with the mixer of frequency 1 through a frequency selection switch to ensure that the uplink signal of frequency 1 can be correctly received. Subsequently, when frequency 2 is the uplink time slot (U in the lower part of Figure 4), the frequency selection switch of receiving channel 1 is adjusted to connect it with the mixer of frequency 2, thereby ensuring that the uplink signal of frequency 2 can also be effectively received.

[0086] Furthermore, when the first communication device is also configured with frequency 3 with a time slot ratio of 4:1, the uplink time slot of frequency 3 can be staggered from the uplink time slots of frequency 1 and frequency 2 by adjusting the starting time point of frequency 3, thereby realizing the multiplexing of the three frequencies in the receiving channel.

[0087] For example, in a scenario with high downlink transmission demand, when frequency 1 is a SUB6GHz frequency and frequency 2 is a millimeter wave frequency, the subcarrier spacing of these two frequency signals is different according to the 3GPP protocol.

[0088] Figure 5 shows a schematic diagram of uplink time slot staggered in a multi-frequency TDD system with the same subcarrier spacing. In this diagram, the downlink to uplink time slot ratio is 4:1 for frequency 1, while it is 8:2 for frequency 2. The subcarrier spacing for frequency 1 is 30kHz, and for frequency 2 it is 120kHz. Correspondingly, the individual time slot lengths for frequencies 1 and 2 are different; the time slot length for the 30kHz subcarrier spacing is four times longer than that for the 120kHz subcarrier spacing.

[0089] Specifically, the start time of frequency 2 is delayed by three time slots (the length of a time slot for frequency 2). Optionally, the start time of frequency 2 can also be delayed by four or five time slots, but this is not limited here.

[0090] Correspondingly, as shown in Figure 5, within the same time domain resources, frequencies 1 and 2 may simultaneously be in downlink time slots. Therefore, to ensure smooth signal transmission, the first communication device configures independent transmission channels for frequencies 1 and 2, namely transmission channel 1 and transmission channel 2. For the millimeter-wave transmission channel of frequency 2, due to the use of a hybrid beamforming (HBF) architecture, it often has fewer channels. A one-to-many connection from one transmission channel to multiple mixers of frequency 2 is achieved through the "power divider network" in Figure 5. Similarly, since the uplink time slots of frequencies 1 and 2 are staggered, switching between frequencies 1 and 2 on demand can be achieved simply by adjusting the frequency selection switch of receiving channel 1 in Figure 5.

[0091] (2) Adjust some time slots of the frequency to idle state.

[0092] As shown in Figure 6, another channel multiplexing scenario is illustrated. Frequency 1 is the TDD frequency, which can be arbitrarily selected from all TDD frequencies defined by 3GPP. For example, a 30kHz frequency with a downlink to uplink time slot ratio of 4:1 can be used. Frequency 2 is the supplementary uplink (SUL) frequency (containing only U), which can also be freely selected from the SUL frequency range defined by 3GPP.

[0093] Specifically, time slots in the SUL frequency that occupy the same time domain resources as the uplink time slots of frequency 1 are adjusted to an idle state to ensure that normal communication between the two frequencies is not interfered with. If there is a difference in subcarrier spacing between frequency 1 and frequency 2, specific time slots in frequency 2 need to be adjusted. Specifically, multiple time slots of equal length that occupy the same time domain resources as the uplink time slots of frequency 1 are set to an idle state to ensure that normal communication between the two frequencies is not interfered with.

[0094] Correspondingly, based on the circuit scheme of the first communication device in Figure 6, the receiving channel multiplexing is realized in this scenario. Frequency 2 only has an uplink time slot or is in an idle state, therefore no transmitting channel is needed. Switching between frequency 1 and frequency 2 can be achieved on demand simply by adjusting the frequency selection switch of receiving channel 1 in Figure 6.

[0095] 302. The first communication device receives or sends data according to the target transmit / receive mode.

[0096] Specifically, the target transceiver mode, as shown in Figures 4 to 6 above, involves adjusting the start time of the frequency and / or setting some frequency time slots to an idle state. This ensures that the uplink time slots of the two frequencies in the first communication device are staggered in the time domain resources, preventing overlap or coexistence of the two uplink time slots. According to this target transceiver mode, a receiving channel in the first communication device can receive data carried by the uplink time slots of these two frequencies in different time units.

[0097] Correspondingly, when the first communication device is a terminal device, according to the target transceiver mode, one of the transmission channels in the terminal device can transmit the data carried by the uplink time slots of the two frequencies in different time units.

[0098] It should be understood that the above examples represent scenarios with high downlink transmission demand, where the uplink time slots on both frequencies account for a relatively small proportion. Therefore, it is possible to stagger the uplink time slots on the two frequencies in the time domain resources, allowing the receiving channel to be multiplexed. Conversely, in scenarios with high uplink transmission demand, where the downlink time slots on both frequencies account for a relatively small proportion, it is also possible to stagger the downlink time slots on the two frequencies in the time domain resources, allowing the transmitting channel to be multiplexed.

[0099] In this application, the timing of the TDD system frame structure for each frequency is adjusted, including adjusting the start time of the frequency and setting some time slots to idle state. This causes the uplink (or downlink) time slots, which account for a smaller proportion of multiple frequencies, to be staggered, so that the uplink (or downlink) only needs one receive channel (or transmit channel) to perform signal reception (or signal transmission) at any given time point. Therefore, according to the channel multiplexing circuit scheme provided in this application, time-division multiplexing of RF channels among multiple frequencies is achieved, reducing the hardware resource requirements of RF channels and lowering the hardware complexity of the system.

[0100] In special cases, both the receiving and transmitting channels can be multiplexed. The ratio of uplink to downlink time slots is always 1:1, or the ratios for the two frequencies are exactly opposite, for example, 4:1 for frequency 1 and 1:4 for frequency 2. In such cases, the receiving and transmitting channels in the communication device can be multiplexed.

[0101] The following example uses a 1:1 ratio of uplink to downlink time slots for both frequencies. As shown in Figure 7, the start time of frequency 2 is delayed by one time slot duration, ensuring that the uplink and downlink time slots between frequencies 1 and 2 are effectively staggered within any time domain resource. The transmit / receive states of frequencies 1 and 2 are switched by adjusting the frequency selection switch and TDD switching switch in Figure 7.

[0102] Specifically, when transmitting channel 1 transmits the D time slot of frequency 1 and receiving channel 1 receives the U time slot of frequency 2, the transmitting channel 1 and receiving channel 1 are connected to the mixer of the corresponding frequency through a switching network (frequency selection switch, TDD switching switch); conversely, when transmitting channel 1 transmits the D time slot of frequency 2 and receiving channel 1 receives the U time slot of frequency 1, the transmitting channel 1 and receiving channel 1 are connected to the mixer of the corresponding frequency through a switching network, thus realizing the sharing of one transmit / receive channel resource between the two frequency bands.
