[0060] In the LTE system, after the first communication device is turned on, it receives the primary synchronization signal (PSS) at several central frequencies where LTE cells may exist, and uses the received signal strength to determine whether there may be cells around the frequency points. If the first communication device stores the frequency point and operator information when it was last turned off, it will first search for the cell where it last resided after turning on; if not, it will perform a full-band scan within the frequency band allocated to the LTE system. The first communication device detects PSS around the central frequency point of the frequency band. PSS occupies 6 physical resource blocks (PRBs) of the central frequency band and repeats with a period of 5ms. By detecting PSS, the terminal can obtain the cell ID in the cell group and determine the 5ms time slot boundary. By detecting PSS, the first communication device can also obtain the length of the cell cyclic prefix and the duplex mode (Frequency Division Duplex (FDD) or Time Division Duplex (TDD)) adopted by the cell. After the 5ms time slot is synchronized, the first communication device will search forward for the secondary synchronization signal (SSS) based on the PSS. The SSS consists of two random sequences, and the mapping of the front and back half frames is just opposite. Therefore, as long as two SSS are received, the 10ms boundary can be determined, achieving the purpose of frame synchronization. Since the SSS signal carries the cell group ID, it can be combined with the PSS to obtain the physical layer ID (cell ID), and further obtain the configuration information of the downlink reference signal. Since both PSS and SSS are sent on the 6 RBs in the middle of the system bandwidth and are sent symmetrically within the bandwidth, the terminal can also obtain frequency synchronization by detecting PSS and SSS. After obtaining frame synchronization, frequency synchronization and downlink reference signal configuration, the terminal further detects the downlink reference signal to obtain accurate time slot and frequency synchronization, and then reads the physical broadcast channel PBCH (Physical broadcast channel, PBCH), obtains the system frame number, bandwidth information, Physical Hybrid ARQ Indicator Channel (Physical Hybrid ARQ Indicator Channel, PHICH) configuration, and antenna configuration and other basic system configuration information, so as to achieve synchronization with the cell.
[0061] The PSS, SSS and PBCH in the NR system constitute the synchronization signal block (Synchronization Signal and Physical broadcast channel block, SSB). The NR system defines the possible time-frequency position of the SSB. The first communication device will try to search for the SSB during the synchronization process. The SSB carries the index information of the SSB, which corresponds to the position of the SSB in the radio frame. Therefore, after obtaining the SSB index, the position of the SSB in the radio frame can be determined, thereby determining the frame boundary of the radio frame and achieving frame synchronization. Specifically, the first communication device first obtains timing synchronization based on the PSS and SSS, and then the terminal further detects the PBCH. The information carried by the PBCH includes MIB information and 8-bit physical layer information. The physical layer information includes SFN, half-frame indication, SSB index, etc. The MIB information carried by the PBCH includes 6 bits of SFN information field, 1 bit of subcarrier spacing information field, 4 bits of subcarrier offset information field of SSB, and 8 bits of PDCCH configuration information field of SIB 1. The first communication device will further read the SIB1 message and other system messages to achieve synchronization with the base station.
[0062] After synchronization is achieved, resource allocation may be performed so that the first communication device may perform data transmission on the allocated resources.
[0063] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.
[0064] In the first part, the application scenarios of the technical solution disclosed in this application are introduced as follows.
[0065] See also Figure 1a , Figure 1a A schematic diagram showing an application scenario of a resource allocation method provided in an embodiment of the present application is shown. Figure 1a As shown, the scenario includes at least one terminal device and a base station 120, for example Figure 1a The terminal device 111 and the terminal device 112 shown in the figure can perform sideline communication with the terminal device 112. In the sideline communication within the network coverage, the terminal device 111 and the terminal device 112 performing the sideline communication are both within the coverage of the base station 120, so that the terminal device 111 and the terminal device 112 can obtain synchronization by receiving the downlink synchronization signal sent by the base station 120, and then receive the system message of the base station 120 to obtain the sideline configuration information.
[0066] See also Figure 1b , Figure 1b A schematic diagram showing an application scenario of another resource allocation method provided in an embodiment of the present application is shown. Figure 1b As shown, the terminal device 111 is located within the coverage of the base station 120, and the terminal device 111 can perform sideline communication with the terminal device 112. In the case of partial network coverage sideline communication, some of the terminal devices 111 performing sideline communication are located within the coverage of the base station 120, so that the terminal device 111 can receive the downlink synchronization signal sent by the base station 120 to obtain synchronization, and then receive the system message sent by the base station 120 to obtain the sideline configuration information. However, the terminal device 112 located outside the network coverage cannot receive the configuration signaling of the base station 120. In this case, the terminal device 112 outside the network coverage needs to receive the sideline synchronization signal and the sideline PBCH sent by the terminal device 111 within the network coverage to obtain synchronization information, and then determine further sideline configuration according to the pre-configuration information.
[0067] See also Figure 1c , Figure 1c FIG. 2 is a schematic diagram showing an application scenario of another resource allocation method provided in an embodiment of the present application. Figure 1c As shown, the terminal device 111 can perform sideline communication with the terminal device 112. For sideline communication outside the network coverage, the terminal device 111 and the terminal device 112 performing sideline communication are both located outside the network coverage. In this case, the terminal device 111 can send a sideline synchronization signal and a sideline PBCH, and the terminal device 112 obtains synchronization information by receiving the synchronization signal and the sideline PBCH, and then determines the sideline configuration according to the pre-configuration information. Alternatively, the terminal device 112 can send a sideline synchronization signal and a sideline PBCH, and the terminal device 111 obtains synchronization information by receiving the synchronization signal and the sideline PBCH, and then determines the sideline configuration according to the pre-configuration information.
[0068] It should be understood that Figure 1a-Figure 1c For ease of understanding only, terminal device 111 and terminal device 112 are schematically shown, but this should not constitute any limitation to the present application. The application scenario may also include a greater number of network devices, and a greater or lesser number of terminal devices. The same network device may communicate with different terminal devices, or different network devices may communicate with different terminal devices. The present application does not limit this.

[0073] The terms used in the implementation mode of this application are only used to explain the specific embodiments of this application, and are not intended to limit this application. The terms "first", "second", "third" and "fourth" in the specification and claims of this application and the drawings are used to distinguish different objects, rather than to describe a specific order. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions.
[0074] In the second part, the protection scope of the claims disclosed in the embodiments of the present application is introduced as follows.
[0075] See also Figure 2 , Figure 2 FIG. 2 is a schematic diagram of a wireless communication system 200 provided in an embodiment of the present application. Figure 2 As shown, the wireless communication system includes a first system 210 and a second system 220. The first system 210 can be applied to Figure 1a-Figure 1c The second system can be applied to Figure 1a-Figure 1c .
[0076] The first system 210 includes a first control node 211 and at least one first communication device 212, and the second system 220 includes a second control node 221 and at least one second communication device 222;
[0077] The second control node 221 is used to obtain position information of a first subcarrier set and / or position information of a second subcarrier set, where the first subcarrier set is a subcarrier set in a superframe occupied by the first system 210, and the second subcarrier set is a subcarrier set in a superframe occupied by the second system 220;
[0078] The first control node 211 is used to determine location information of the first subcarrier set.
[0079] The first system 210 may be a short-distance communication system such as an in-vehicle communication system, a home communication system, an indoor communication system, a wearable communication system, etc.; the second system may also be a short-distance communication system such as an in-vehicle communication system, a home communication system, an indoor communication system, a wearable communication system, etc. This embodiment of the application does not limit this.
[0080] Specifically, in the in-car communication scenario, the car includes a variety of first communication devices, such as: central controller, microphone, speaker, rearview mirror, driving recorder, 360-degree surround view, door lock control, seat control, air conditioning control, lighting control, etc. The terminals in the car can be divided into different communication groups or form different subsystems, namely the first system or the second system. For example, the telematics BOX (T-box) in the car can form a first system with the microphone, audio, etc. in the car; the cockpit controller in the car and the windows, doors, lights, seats, etc. form a first system; the central controller in the car and the microphone, speaker, rearview mirror, etc. form a second system; the smart key intelligent entry and start system (Passive Entry Passive Start, PEPS) in the car and the door locks, keys, etc. form a first system, etc. The first communication device in the car can be controlled by the first control node or the second control node in the car. Among them, there is a first control node in each first system, and a second control node in each second system. The second control node can control multiple devices in the first system, and the first control node can control the devices in the first system where the first control node is located. In the smart home scenario, the first communication device in the home or indoors has a communication function, and the first communication devices in the home can constitute the second system and / or multiple first systems. Each of the first systems has a corresponding first control node. For example, the smart air conditioner, smart refrigerator and smart washing machine in the home can constitute the first system, and the smart phone, smart TV and user terminal equipment (Consumer Premise Equipment, CPE) in the home can constitute the second system. In addition, other families may also have the first system and / or the second system. These first systems and second systems usually use the same wireless transmission method to communicate within the same carrier and bandwidth.
[0081] Among them, the above-mentioned first communication device and the second communication device can be terminal devices, mobile devices, user terminals, vehicle-mounted terminals, wearable devices and other electronic devices, which are not limited in this embodiment of the present application.
[0082] The superframe includes i wireless frames, each of the wireless frames includes multiple time domain symbols, the time domain symbols are C link symbols or T link symbols, a Gap symbol is included between the C link symbol and the T link symbol, and i is a positive integer.
[0083] In the embodiments of the present application, Figure 3As shown, in the frequency domain, each superframe can contain 40 subcarriers, and N is a positive integer less than or equal to 40. In the time domain, each superframe contains 48 radio frames, that is, i is 48, and each radio frame includes 8 time domain symbols. Different time domain symbols in the radio frame can be configured as C-link symbols or T-link symbols. The C-link symbol is used for data transmission of the C-link method, and the T-link symbol is used for data transmission in the T-link direction. The C-link direction is the direction in which the first control node or the second control node sends data to the first communication device, and the T-link direction is the direction in which the first communication device sends data to the first control node or the second control node. Among them, the C-link symbol or the T-link symbol can be located at any position in the radio frame, for example, Figure 3 As shown, the C link symbol is located in the first 4 symbols of the radio frame, and the T link symbol is located in the last 4 symbols of the radio frame. There is a guard period (Gap) symbol between the C link symbol and the T link symbol. The Gap symbol is usually used for transceiver conversion or transceiver conversion.
[0084] Among them, in the in-vehicle short-distance communication system, the subcarrier spacing is 480kHz, a radio frame includes 8 OFDM symbols, the duration is 20.833us, and the duration of 48 radio frames is 1ms, corresponding to a superframe. In the 3GPP NR system, for a 15kHz subcarrier spacing, the length of a time slot is 1ms, for a 30kHz subcarrier spacing, the length of a time slot is 0.5ms, and so on.
[0085] It should be noted that Figure 3 The structure of the superframe and the radio frame is schematically shown for ease of understanding only, but this should not constitute any limitation to the present application, and the method in the present application is still applicable to other types of superframe and radio frame structures.
[0086] Among them, the resources allocated to the first system (i.e., the first subcarrier set) are used for the first control node in the first system and the first communication device in the first system. When the first control node and / or the first communication device in the first system need to communicate, the first subcarrier set can be occupied for data transmission. The resources allocated to the second system (i.e., the second subcarrier set) are used for the second control node in the second system and the second communication device in the second system. When the second control node and / or the second communication device in the second system need to communicate, the second subcarrier set can be occupied for data transmission. It should be noted that the first control node and / or the first communication device can occupy the first subcarrier set to send data to the second control node, and the second control node can occupy the second subcarrier set to send data to the first control node and / or the first communication device, that is, the device in the first system occupies the first subcarrier set for data transmission, and the device in the second system occupies the second subcarrier set for data transmission.
[0087] In a possible embodiment, when the time domain position corresponding to the first subcarrier set is a Gap symbol and the transmission direction of the first system in the superframe is different from the transmission direction of the next superframe, the first subcarrier set is located in any Gap symbol in the superframe except the last Gap symbol of the last wireless frame.
[0088] Specifically, when the time domain position corresponding to the first subcarrier set can be a Gap symbol in a radio frame, the first control node and / or the first communication device in the first system can perform data transmission in the C link direction or the T link direction on the subcarrier set at the frequency domain position corresponding to the Gap symbol. In this case, if the transmission direction of the first system in the next superframe is different from the transmission direction of the first subsystem in the current superframe, the last Gap symbol of the last radio frame of the current superframe cannot be used for data transmission by the device in the first system.
[0089] In a possible embodiment, when the second system occupies the first subcarrier set in part or all of the superframe, on a first symbol, the transmission direction of the first subcarrier set is the same as or different from the transmission direction of the second subcarrier set, and the first symbol is any OFDM symbol in the wireless frame.
[0090] In order to improve the utilization rate of frequency domain resources, the second system may use the first subcarrier set under certain conditions. When the second system may occupy the first subcarrier set in part of the superframe or all of the superframe, the transmission direction of the first subcarrier set is the same as or different from the transmission direction of the second subcarrier set, that is, the transmission direction of the first subcarrier set on each symbol in the wireless frame is the same as the configuration of the second system. For example, assuming that the transmission method of the second subcarrier in the second system is as follows Figure 3 As shown, the transmission direction of the first 4 symbols of the wireless frame in the superframe is the C-link direction, and the transmission direction of the last 4 symbols is the T-link direction; when the second system occupies the first subcarrier set, the transmission direction of the first subcarrier set at the frequency domain position corresponding to the first 4 symbols in the wireless frame is the C-link direction, and the transmission direction of the first subcarrier set at the frequency domain position corresponding to the last four symbols of the wireless frame is the T-link direction, that is, the symbol ratio within the wireless frame in the superframe occupied by the first system and the second system is the same.
[0091] For example, in the in-vehicle communication scenario, assuming that the first system is the PEPS subsystem, and the second system is a subsystem that supports in-vehicle voice and time-frequency services, when the vehicle is not started, the PEPS subsystem occupies the first subcarrier set, and the time-frequency resources occupied by the second system have a protection interval of at least G subcarriers between the first subcarrier set in the frequency domain. When the vehicle is started, the PEPS subsystem is in a stopped working state. In this case, the second subsystem can occupy the first subcarrier set.
[0092] In this embodiment of the present application, a guard interval is included between the first subcarrier set and the second subcarrier set.
[0093] In order to reduce in-band leakage interference between different systems, there may be a protection interval of G subcarriers between the first subcarrier set occupied by the first system and the second subcarrier set occupied by the second system, and / or there may be a protection interval of G subcarriers between the first subcarrier set occupied by the first system and the subcarrier sets occupied by other first systems, and / or there may be a protection interval of G subcarriers between the second subcarrier set occupied by the second system and the subcarrier sets occupied by other first systems, and no system may occupy the protection interval of G subcarriers.
[0094] In a possible embodiment, the first subcarrier set and the second subcarrier set are continuous in the frequency domain.
[0095] Among them, when the time when the first system occupies the first subcarrier set to send data is different from the time when the second system occupies the second subcarrier set to send data, there will be no in-band leakage between the first system and the second system. At this time, the first subcarrier set and the second subcarrier set can be continuous in the frequency domain. For example, in an in-vehicle communication scenario, assuming that the first system is a PEPS subsystem and the second system is a subsystem that supports in-vehicle voice and time-frequency services, when the vehicle is not started, the PEPS subsystem occupies the first subcarrier set and the second system occupies the second subcarrier set; when the vehicle is in the started state, the PEPS subsystem is in the stopped working state. In this case, the second subcarrier set and the first subcarrier set can be continuous in the frequency domain.
[0096] Optionally, when the time domain positions corresponding to the first subcarrier set and the second subcarrier set are both C link symbols or T link symbols, the difference between the transmit power of any subcarrier in the first subcarrier set and the transmit power of any subcarrier in the second subcarrier set is less than a preset threshold.
[0097] Among them, when the first system and the second system are geographically close, or the difference between the transmission power of any subcarrier in the first subcarrier set and the transmission power of any subcarrier in the second subcarrier set is less than a preset threshold, the near-far effect caused by the first system and the second system is weak, and the second control node can configure or pre-configure the first subcarrier set and the second subcarrier set to be continuous in the frequency domain.
[0098] For example, it is assumed that the first control node of the first system and the second control node of the second system are very close in geographical location, and the first control node in the first system occupies the first subcarrier set at the frequency domain position corresponding to the C-link symbol to send data in the C-link direction, and the second control node in the second system occupies the other subcarrier sets at the frequency domain position corresponding to the C-link symbol to send data in the C-link direction. In this case, since the transmission power on each subcarrier sent by the second control node and the first control node received by the first communication device is close, the near-far effect is weak, so no protection subcarrier may be left between the first subcarrier set and the second subcarrier set.
[0099] For example, assuming that the first control node of the first system and the second control node of the second system are geographically very close, the first communication device in the first system occupies the first subcarrier set at the frequency domain position corresponding to the T link symbol to send data in the T link direction, and the second control node in the second system occupies the other subcarrier sets at the frequency domain position corresponding to the T link symbol to send data in the T link direction. In this case, since the signal power received by the second control node and the first control node from the first communication device in the first system is close, the near-far effect is weak, so no guard subcarrier may be left between the first subcarrier set and the second subcarrier set.
[0100] In an embodiment of the present application, position information of a first subcarrier set and / or position information of a second subcarrier set is obtained through a second control node, the first subcarrier set is a subcarrier set in a superframe occupied by the first system, the second subcarrier set is a subcarrier set in a superframe occupied by the second system, and the position information of the first subcarrier set is determined through a control node, so that effective resource coordination between the first system and the second system on the same carrier can be achieved to avoid interference between the systems.
[0101] See also Figure 4 , Figure 4 is a flow chart of a resource allocation method provided in an embodiment of the present application, and the method is applied to Figure 1a-Figure 1c The application scenarios described above, and Figure 2 The wireless communication system. Figure 4 As shown, the resource allocation method includes the following steps.
[0102] S410. A first communication device obtains position information of a first subcarrier set, where the first subcarrier set is used for communication of a first system, and the first system includes the first communication device and a first control node. The position of the first subcarrier set is determined based on the position information, and the position information includes at least one of the following: time domain position information of the first subcarrier set and frequency domain position information of the first subcarrier set.
[0103] Optionally, the time domain position information includes position information of the first subcarrier set in a superframe.
[0104] Optionally, the location information also includes the number N of subcarriers in the first subcarrier set, where N is a positive integer.
[0105] The first communication device may determine the location information of the first subcarrier set through pre-configuration. For example, the first communication device may determine that the first subcarrier set is located at the last 10 consecutive subcarriers of the superframe according to the pre-configuration.
[0106] In some examples, the first communication device may receive first configuration information sent by a first control node in the first system, the first configuration information may include the location information, and the first communication device may determine the location information of the first subcarrier set according to the first configuration information. In some examples, the first communication device receives the first configuration information sent by the first control node in the first system.
[0107] Among them, the first communication device can also receive first configuration information sent by the second control node in the second system, and the first configuration information may include the location information, and the first communication device can determine the location information of the first subcarrier set based on the first configuration information. In some examples, when the first communication device receives the first configuration information sent by the first control node in the first system and the second control node in the second system, the first communication device can determine the location information of the first subcarrier set through the first configuration information sent by the first control node in the first system. In some examples, when the first communication device receives the first configuration information sent by the first control node in the first system and / or the second control node in the second system, the first communication device can still determine the location information of the first subcarrier set through pre-configuration.
[0108] It should be noted that the above method can also be applied to the second communication device in the second system. When applied to the second communication device, the first control node in the method is the second control node.
[0109] It can be seen that in the embodiment of the present application, the first communication device obtains the position information of the first subcarrier set, the first subcarrier set is used for communication of the first system, the first system includes the first communication device and the first control node, and the position of the first subcarrier set is determined according to the position information, and the position information includes at least one of the following: time domain position information of the first subcarrier set and frequency domain position information of the first subcarrier set. The time and frequency resources that can be used by the device of the first system are determined by the first communication device, thereby realizing resource allocation of the first system.
[0110] See also Figure 5 , Figure 5 is a flow chart of a resource allocation method provided in an embodiment of the present application, and the method is applied to Figure 1a-Figure 1c The application scenarios described above, and Figure 2 The wireless communication system. Figure 5 As shown, the resource allocation method includes the following steps.
[0111] S510. A first control node obtains position information of a first subcarrier set, where the first subcarrier set is used for communication of a first system, and the first system includes the first communication device and a first control node. The position of the first subcarrier set is determined based on the position information, and the position information includes at least one of the following: time domain position information of the first subcarrier set and frequency domain position information of the first subcarrier set.
[0112] Optionally, the location information also includes the number N of subcarriers in the first subcarrier set, where N is a positive integer.
[0113] In an embodiment of the present application, the first system includes a first control node and at least one first communication device. The first control node can determine the number N of subcarriers in the first subcarrier set occupied by the first system in a superframe and the frequency domain position of the first subcarrier set through preconfiguration.
[0114] The first control node may determine, through preconfiguration, a specific subcarrier set occupied by the first system within a superframe, for example, Figure 6a As shown, the first system may occupy the first N consecutive subcarriers in the superframe. In the embodiment of the present application, N is a positive integer less than or equal to 40.
[0115] It should be noted that the first subcarrier set may be any continuous N subcarriers in a superframe, or may be any non-continuous N subcarriers in a superframe, and this embodiment of the present application does not limit this.
[0116] Optionally, the time domain position information includes position information of the first subcarrier set in a superframe.
[0117] In a possible embodiment, when part or all of the time domain positions corresponding to the first subcarrier set are the Gap symbols, the position information also includes the time domain positions of the Gap symbols.
[0118] The first control node may determine the time domain position of the Gap symbol occupied by the first system, the number N of subcarriers in the first subcarrier set occupied by each Gap symbol, and the frequency domain position of the first subcarrier set through pre-configuration. For example, the first control node may determine the subcarrier set on all Gap symbols of all radio frames in the superframe occupied by the first system through pre-configuration, such as Figure 6b As shown; in some examples, the first control node can determine the subcarrier set on the first or second Gap symbol of all radio frames in the superframe occupied by the first system through preconfiguration. In some examples, the first control node can determine the subcarrier set on all Gap symbols of some radio frames in the superframe occupied by the first system through preconfiguration. In some examples, the first control node can determine the subcarrier set on the first or second Gap symbol of some radio frames in the superframe occupied by the first system through preconfiguration. Further, the first system can occupy some or all subcarriers at the frequency domain position corresponding to the Gap symbol.
[0119] In a possible embodiment, when the time domain positions corresponding to the first subcarrier set are partly C-link symbols or all C-link symbols, or when the time domain positions corresponding to the first subcarrier set are partly T-link symbols or all T-link symbols, the position information also includes the symbol position of the C-link symbol or the T-link symbol.
[0120] Among them, the first control node can determine the number N of subcarriers in the first subcarrier set in the superframe occupied by the first system, the frequency domain position of the first subcarrier set, and the symbol position of the time domain position corresponding to the first subcarrier set through preconfiguration. The symbol position can be partially or entirely C-link symbols, or partially or entirely T-link symbols.
[0121] Specifically, the C-link symbol or T-link symbol of the first system may occupy a specific subcarrier set on a specific symbol within a superframe, for example, Figure 6cAs shown, the C-link symbol of the first system occupies the first N consecutive subcarriers on all C-link symbols in the superframe. In some examples, the T-link symbol of the first system occupies the first N consecutive subcarriers on some C-link symbols in the superframe. In some examples, the T-link symbol of the first system occupies the first N consecutive subcarriers on some or all T-link symbols in the superframe. The N subcarriers in a superframe are only used for transmission in one direction of the first system, the C-link method or the T-link direction.
[0122] In an embodiment of the present application, the method further includes: determining a transmission direction of the first subcarrier set, where the transmission direction includes a C-link direction or a T-link direction.
[0123] The first control node in the first system may further determine the transmission direction of the first subcarrier set on each radio frame within a period.
[0124] Optionally, the transmission direction of the first subcarrier set of all radio frames of the superframe is a C-link direction or a T-link direction.
[0125] Specifically, the first subcarrier set in a superframe can be used for transmission in one direction of the first system (C link direction or T link direction), S superframes can form a cycle, the first P superframes in the cycle can be used for data transmission in the C link direction, and the subsequent SP superframes can be used for data transmission in the T link direction. The value of P can be determined by the first control node in the first system. For example, Figure 6d As shown, S=10, P=9, the first 9 superframes in the cycle can be used for data transmission in the C link direction, and the last superframe can be used for data transmission in the T link direction. In some examples, the even superframes in the S cycle can be used for data transmission in the C link direction, and the odd superframes can be used for data transmission in the T link direction. In other examples, all superframes in the first system can also be used for data transmission in the C link direction or data transmission in the T link direction. Of course, the embodiments of the present application are not limited to other methods for determining the transmission direction.
[0126] Optionally, the transmission direction of the first subcarrier set on the m radio frames in the superframe is the C link direction, the transmission direction of the subcarrier set on the k radio frames in the superframe is the T link direction, and the sum of m and k is less than or equal to i.
[0127] Specifically, the first subcarrier set on different radio frames within a superframe can be used for transmission in different directions of the first system. For example, the first subcarrier set in the first 24 radio frames within a superframe is used for data transmission in the C link direction, and the first subcarrier set in the last 24 radio frames is used for data transmission in the T link direction.
[0128] Optionally, when the time domain position corresponding to the first subcarrier set is partially the C-link symbol, or is entirely the C-link symbol, the transmission direction of the first subcarrier set of all the superframes is the C-link direction; when the time domain position corresponding to the first subcarrier set is partially the T-link symbol, or is entirely the T-link symbol, the transmission direction of the first subcarrier set of all the superframes is the T-link direction.
[0129] Specifically, if the time domain position corresponding to the first subcarrier set is a C-link symbol in a wireless frame, the first subcarrier set in all superframes is used for data transmission in the C-link direction; conversely, if the time domain position of the first subcarrier set is a T-link symbol in a wireless frame, the first subcarrier set in all superframes is only used for data transmission in the T-link direction.
[0130] Optionally, when the time domain position corresponding to the first subcarrier set is the Gap symbol, the time length for sending an OFDM symbol on the Gap symbol is L. The time length L of the OFDM symbol is the same as the time length of the Gap symbol.
[0131] When the first control node sends data on the Gap symbol, the first control node needs to generate an OFDM symbol with a time length of 64*Ts, or generate an OFDM symbol with a time length of (64+X)*Ts, where 64*Ts is the data part, X*Ts is the cyclic prefix, X can be 5 or 14, and Ts=1 / (480000×64) seconds. In the embodiment of the present application, the time length of the Gap symbol is 44*Ts, that is, L=44*Ts. Therefore, Figure 6e As shown, only the last 44*Ts of the above OFDM symbol are sent on the Gap symbol.
[0132] Optionally, the subcarriers in the subcarrier set carrying valid data in the frequency domain position corresponding to the above-mentioned OFDM symbol are distributed at intervals.
[0133] Specifically, Figure 6eAs shown, when the first control node sends data on the Gap symbol, the modulated OFDM symbol can be mapped to the even subcarriers of the superframe and an OFDM symbol with a time length of 64*Ts can be generated, or an OFDM symbol with a time length of (64+X)*Ts can be generated, and then only the last 44*Ts of the OFDM symbol can be sent on the Gap symbol. In some examples, when the first control node sends data on the Gap symbol, the modulated OFDM symbol can be mapped to the odd subcarriers of the superframe and an OFDM symbol with a time length of 64*Ts can be generated, or an OFDM symbol with a time length of (64+X)*Ts can be generated, and then only the last 44*Ts of the OFDM symbol can be sent on the Gap symbol.
[0134] In a possible embodiment, the method further includes: sending second configuration information to the first communication device, where the second configuration information is used to determine a transmission direction of the first subcarrier set in the superframe.
[0135] S520. The first control node sends first configuration information to the first communication device, where the first configuration information includes location information.
[0136] S530. The first communication device receives first configuration information from the first control node, and determines location information of the first subcarrier set based on the first configuration information.
[0137] Among them, for the first communication device within the first system, the number N of subcarriers in the first subcarrier set that the first system can occupy in the superframe and the frequency domain position of the first subcarrier set can be determined by receiving the first configuration information sent by the first control node in the first system, so as to send or receive data at the frequency domain position of the corresponding first subcarrier set.
[0138] In a possible embodiment, when part or all of the time domain positions corresponding to the first subcarrier set are the Gap symbols, the position information also includes the time domain positions of the Gap symbols.
[0139] After receiving the first configuration information sent by the first control node, the first communication device can determine the time domain position of the Gap symbol available to the first system, the number N of subcarriers in the first subcarrier set occupied by each Gap symbol, and the frequency domain position of the first subcarrier set. Figure 6bAs shown, according to the first configuration information, the first communication device can determine that the first system can occupy all Gap symbols of some radio frames in the superframe. In some examples, the first system can occupy some Gap symbols of some radio frames in the superframe, or can occupy some Gap symbols of all radio frames in the superframe, or can occupy all Gap symbols of all radio frames in the superframe. The first system can occupy some subcarriers or all subcarriers at the frequency domain position corresponding to the Gap symbol.
[0140] In a possible embodiment, when the time domain positions corresponding to the first subcarrier set are partly C-link symbols or all C-link symbols, or when the time domain positions corresponding to the first subcarrier set are partly T-link symbols or all T-link symbols, the position information also includes the symbol position of the C-link symbol or the T-link symbol.
[0141] After receiving the first configuration information sent by the first control node, the first communication device can determine the symbol position of the first system in the time domain for the C link direction or the symbol position for the T link direction, as well as the number N of subcarriers in the first subcarrier set in the frequency domain and the frequency domain position of the first subcarrier set. Figure 6c As shown, according to the first configuration information, the first communication device can determine that the first system can occupy the first N consecutive subcarriers of the frequency domain positions corresponding to all C-link symbols of all radio frames in the superframe.
[0142] In an embodiment of the present application, the method further includes: determining a transmission direction of the first subcarrier set, where the transmission direction includes a C-link direction or a T-link direction.
[0143] The first communication device may receive the second configuration information sent from the first control node to determine the transmission direction of the first subcarrier set. Specifically, the first communication device may determine, based on the second configuration information, that the first subcarrier set in a superframe within the first system can be used only for transmission in one direction of the first system, or determine that the first subcarrier set on different subcarriers in a superframe within the first system can be used for transmission in different directions of the first system.
[0144] Specifically, the first communication device may determine, based on the second configuration information, that all superframes in the first system are used for the C link or the T link. For example, the time domain position corresponding to the first subcarrier set may be located on all C link symbols in a superframe, or the time domain position corresponding to the first subcarrier set may be located on some C link symbols of a specific radio frame in a superframe; or the time domain position corresponding to the first subcarrier set may be located on all C link symbols of some radio frames in a superframe.
[0145] Further, when the time domain position corresponding to the first subcarrier set is the Gap symbol, the first communication device can determine the transmission direction of the Gap symbol available to the first subsystem in each superframe according to the second configuration information. For example, the first communication device can determine that the transmission method of the Gap symbol available to the first system in all superframes is the C link direction according to the second configuration information.
[0146] In some examples, the first communication device may also determine the transmission direction of the first subcarrier set in each superframe by preconfiguration, or, after receiving the second configuration information, the first communication device still determines the transmission direction of the first subcarrier set in each superframe by preconfiguration. For example, the first communication device may determine that all superframes in the first system are used for the C link according to the preconfiguration, or the first communication device may determine that the transmission method of the Gap symbols available to the first system in all superframes is the C link direction according to the preconfiguration.
[0147] It should be noted that the above method can also be applied to the second communication device in the second system. When applied to the second communication device, the first control node in the method is the second control node.
[0148] It can be seen that the first control node obtains the position information of the first subcarrier set, the first subcarrier set is used for communication of the first system, and the first system includes the first communication device and the first control node; according to the position information, the position of the first subcarrier set is determined; the position information includes at least one of the following: time domain position information of the first subcarrier set and frequency domain position information of the first subcarrier set; the first control node sends first configuration information to the first communication device, and the first configuration information includes position information; the first communication device receives the first configuration information from the first control node, and determines the position information of the first subcarrier set based on the first configuration information. In the present application, the first control node can determine the time and frequency resources that can be used by the first system according to the pre-configuration, realizes the resource allocation within the first system, and uniformly allocates resources through the first control node, which can avoid interference with other systems.
[0149] See also Figure 7 , Figure 7 is a flow chart of a resource allocation method provided in an embodiment of the present application, and the method is applied to Figure 1a-Figure 1c The application scenarios described above, and Figure 2 The wireless communication system. Figure 7 As shown, the resource allocation method includes the following steps.
[0150] S710. The second control node sends first configuration information to the first control node, where the first configuration information is used to obtain position information of a first subcarrier set, where the first subcarrier set is used for communication of a first system, where the first system includes the first communication device and a first control node, and the position information includes at least one of the following: time domain position information of the first subcarrier set and frequency domain position information of the first subcarrier set.
[0151] In an embodiment of the present application, the first system includes a first control node and at least one first communication device, the second system includes a second control node and at least one second communication device, and the second control node may be responsible for coordinating the time and frequency resources used by multiple first systems. The second control node may broadcast the first configuration information to the first control node in the first system to determine the time and frequency resources that can be used by the first system.
[0152] Optionally, the location information also includes the number N of subcarriers in the first subcarrier set, where N is a positive integer.
[0153] The second control node may configure the first system to occupy a specific subcarrier set within the superframe, for example, Figure 6a As shown, the first system may occupy the first N consecutive subcarriers in the superframe.
[0154] It should be noted that the first subcarrier set may be any continuous N subcarriers in a superframe, or may be any non-continuous N subcarriers in a superframe, and this embodiment of the present application does not limit this.
[0155] Optionally, the time domain position information includes position information of the first subcarrier set in a superframe.
[0156] In a possible embodiment, the second control node may configure that the time domain position corresponding to the first subcarrier set occupied by the first system is partially or entirely the Gap symbol. And when the time domain position corresponding to the first subcarrier set is partially or entirely the Gap symbol, the position information also includes the time domain position of the Gap symbol.
[0157] like Figure 6b As shown, the second control node can configure the first system to occupy all Gap symbols of part or all radio frames in a superframe. In some examples, the second control node can configure the first system to occupy some Gap symbols of part or all radio frames in a superframe. The first system can occupy some subcarrier sets or all subcarrier sets at frequency domain positions corresponding to the Gap symbols.
[0158] Specifically, the second control node can configure the time domain position of the Gap symbol occupied by the first system, as well as the number N of subcarriers in the first subcarrier set occupied on each Gap symbol and the frequency domain position of the first subcarrier set. For example, the second control node can configure the first system to occupy the first subcarrier set on all Gap symbols of all wireless frames within a superframe, or occupy the first subcarrier set on the first or second Gap symbol of all wireless frames within a superframe, or occupy the first subcarrier set on the Gap symbol of part of the wireless frames within a superframe, or occupy the first subcarrier set on the first or second Gap symbol of part of the wireless frames within a superframe.
[0159] In a possible embodiment, the second control node may configure the first system to occupy part of the time domain positions corresponding to the first subcarrier set as C-link symbols or all of them as C-link symbols, or the second control node may configure the first system to occupy part of the time domain positions corresponding to the first subcarrier set as T-link symbols or all of them as T-link symbols. When the time domain positions corresponding to the first subcarrier set are part of the C-link symbols or all of them as C-link symbols, or the time domain positions corresponding to the first subcarrier set are part of the T-link symbols or all of them as T-link symbols, the position information also includes the symbol position of the C-link symbol or the T-link symbol.
[0160] like Figure 6c As shown, the second control node can configure the C-link symbol or T-link symbol of the first system to occupy a specific subcarrier set on a specific symbol in a superframe. For example, the second control node can configure the C-link symbol of the first system to occupy the first N consecutive subcarriers on some or all C-link symbols in a superframe, or the T-link symbol of the first system to occupy the first N consecutive subcarriers on some or all T-link symbols in a superframe. The N subcarrier set in a superframe is only used for transmission in one direction of the first system, the C-link method or the T-link direction.
[0161] S720. The first control node receives first configuration information from the second control node, and determines location information of a first subcarrier set based on the first configuration information.
[0162] Among them, the first control nodes in multiple first systems can determine the time-frequency resources that can be used by the first system to which the first control node belongs, that is, the position information of the first subcarrier set in the superframe, by receiving the first configuration information broadcast by the second control node in the second system.
[0163] S730. The first control node sends first configuration information to the first communication device.
[0164] S740. The first communication device receives first configuration information from the first control node, and the first communication device determines position information of a subcarrier set in a superframe based on the first configuration information.
[0165] The specific description of S720-S740 can refer to the above Figure 5 The corresponding steps of the described resource allocation method will not be repeated here.
[0166] It can be seen that the second control node sends the first configuration information to the first control node, the first configuration information is used to obtain the position information of the first subcarrier set, the first subcarrier set is used for communication of the first system, the first system includes the first communication device and the first control node, and the position information includes at least one of the following: time domain position information of the first subcarrier set and frequency domain position information of the first subcarrier set; the first control node receives the first configuration information from the second control node, and determines the position information of the subcarrier set in the superframe based on the first configuration information; the first control node sends the first configuration information to the first communication device; the first communication device receives the first configuration information from the first control node, and the first communication device determines the position information of the subcarrier set in the superframe based on the first configuration information. In the present application, the time-frequency resources that can be used by the first system are configured by the second control node, so that resource allocation within the first system is realized, and the second control node uniformly allocates resources, so that effective resource coordination of multiple systems on the same carrier can be realized to avoid interference with multiple systems.
[0167] See also Figure 8 , Figure 8 is a flow chart of a resource allocation method provided in an embodiment of the present application, and the method is applied to Figure 1a-Figure 1c The application scenarios described above, and Figure 2 The wireless communication system.
