Detailed Description

In an LTE system, after being started, first communication equipment receives Primary Synchronization Signals (PSS) at a plurality of central frequency points where LTE cells possibly exist, judges whether the cells possibly exist around the frequency points according to the received signal strength, and searches cells resided last time after starting if the first communication equipment stores the frequency points and operator information when the first communication equipment is shut down last time; and if not, performing full-band scanning in the frequency band range divided to the LTE system. The first communication device detects the PSS around a center frequency point of a frequency band, and the PSS occupies 6 Physical Resource Blocks (PRBs) of the center frequency band and repeats with 5ms as a cycle. The method comprises the steps that a PSS terminal is detected to obtain a cell ID in a cell group, a 5ms Time slot boundary is determined at the same Time, and the length of a cell cyclic prefix and a Duplex mode (Frequency Division Duplex (FDD) or Time-Division Duplex (TDD)) adopted by a cell can be obtained by detecting a PSS first communication device. After 5ms time slot Synchronization, the first communication device will search forward for Secondary Synchronization Signals (SSS) based on PSS, the SSS is composed of two random sequences, and the mapping of the front and rear half-frames is just opposite, so that the 10ms boundary can be determined as long as the two SSS are received, thereby achieving the purpose of frame Synchronization. Since the SSS signal carries the cell group ID, the SSS signal can obtain a physical layer ID (cell ID) by combining with the PSS, and further obtain configuration information of the downlink reference signal. Since both PSS and SSS are transmitted on 6 RBs in the middle of the system bandwidth, symmetrically within the bandwidth, frequency synchronization can also be achieved by detecting PSS and SSS terminals. After obtaining frame synchronization, frequency synchronization and downlink reference signal configuration, the terminal further detects the downlink reference signal so as to obtain accurate time slot and frequency synchronization, then reads a Physical Broadcast Channel (PBCH) of a broadcast Channel PBCH, obtains system frame number, bandwidth information, physical Hybrid ARQ Indicator Channel (PHICH) configuration, and system basic configuration information such as antenna configuration, thereby achieving synchronization with a cell.

The PSS, the SSS, and the PBCH in the NR system constitute a Synchronization Signal Block (SSB), the NR system defines a possible time-frequency location of the SSB, the first communication device tries to search for the SSB during Synchronization, the SSB carries index information of the SSB, and the index corresponds to the position of the SSB in the wireless frame one-to-one, so that the position of the SSB in the wireless frame can be determined after the SSB index is obtained, thereby determining the frame boundary of the wireless frame, and implementing frame Synchronization. Specifically, the first communication device first obtains timing synchronization according to the PSS and the SSS, and then the terminal further detects the PBCH, where 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 SFN information field 6 bits, subcarrier spacing information field 1 bits, subcarrier offset information field 4 bits of SSB and PDCCH configuration information field 8 bits of SIB 1. The first communication device will further read the SIB1 message and other system messages to achieve synchronization with the base station.

After synchronization is achieved, resource allocation can be performed such that the first communication device can perform data transmission on the allocated resources.

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be obtained by a person skilled in the art without making any creative effort based on the embodiments in the present invention, shall fall within the protection scope of the present invention.

In the first section, the application scenarios of the technical solutions disclosed in the present application are described as follows.

Referring to fig. 1a, fig. 1a is a schematic diagram illustrating an application scenario of a resource allocation method according to an embodiment of the present application. As shown in fig. 1a, the scenario includes at least one terminal device and a base station 120, for example, the terminal device 111 and the terminal device 112 shown in fig. 1a, and the terminal device 111 may perform a sidelink communication with the terminal device 112. In the sidestream communication within the network coverage, both the terminal device 111 and the terminal device 112 performing the sidestream communication are within the coverage of the base station 120, so that both the terminal device 111 and the terminal device 112 may obtain synchronization by receiving the downlink synchronization signal transmitted by the base station 120, and then receive the system message of the base station 120 to obtain the sidestream configuration information.

While terminal devices 112 located outside the network coverage area cannot receive configuration signaling of base station 120.

In the second section, the claims disclosed in the embodiments of the present application are presented below.

Referring to fig. 2, fig. 2 is a schematic structural diagram of a wireless communication system 200 according to an embodiment of the present disclosure. As shown in fig. 2, the wireless communication system includes a first system 210 and a second system 220, the first system 210 can be applied to fig. 1 a-1 c, and the second system can be applied to fig. 1 a-1 c.

Wherein the first system 210 comprises a first control node 211 and at least one first communication device 212, and the second system 220 comprises a second control node 221 and at least one second communication device 222;

the second control node 221 is configured to obtain location information of a first subcarrier set and/or location information of a second subcarrier set, where the first subcarrier set is a subcarrier set occupied in a superframe by the first system 210, and the second subcarrier set is a subcarrier set occupied in a superframe by the second system 220;

The embodiment of the present application does not limit this.

Specifically, in an in-vehicle communication scenario, a variety of first communication devices are included in a vehicle, such as: the system comprises a central controller, a microphone, a loudspeaker, a rearview mirror, a driving recorder, a 360-degree look-around, a door lock control, a seat control, an air conditioner control, a light control and the like. Terminals in the vehicle can be divided into different communication groups or form different subsystems, namely a first system or a second system, for example, a Telematics BOX (T-BOX) in the vehicle can form a first system together with a microphone, a sound and the like in the vehicle; a cabin controller in the automobile, windows, doors, lights, seats and the like form a first system; a central controller in the vehicle, a microphone, a sound box, a rearview mirror and the like form a second system; a Passive Entry Passive Start (PEPS) system in the vehicle, a door lock, a key, and the like form a first system, and the like. The first communication device in the vehicle may be controlled by the first control node or the second control node in the vehicle. Each first system has a first control node, each second system has a second control node, the second control node can control a plurality of devices in the first system, and the first control node can control the device in the first system in which the first control node is located. In an intelligent home scene, a home or an indoor first communication device has a communication function, the second system and/or a plurality of first systems may be formed among the first communication devices in the home, each first system has a corresponding first control node therein, for example, a smart air conditioner, a smart refrigerator, and a smart washing machine in the home may form the first system, a smart phone, a smart television, and a Customer Premises Equipment (CPE) in the home may form the second system, and in addition, the first system and/or the second system may exist in other homes. These first and second systems typically communicate using the same wireless transmission scheme within the same carrier and bandwidth.

The first communication device and the second communication device may be other electronic devices such as a terminal device, a mobile device, a user terminal, a vehicle-mounted terminal, and a wearable device, which is not limited in this embodiment of the present application.

The superframe comprises i wireless frames, each wireless frame comprises a plurality of time domain symbols, the time domain symbols are C link symbols or T link symbols, gap symbols are included between the C link symbols and the T link symbols, and i is a positive integer.

In the embodiment of the present application, as shown in fig. 3, each superframe may include 40 subcarriers in the frequency domain, where N is a positive integer less than or equal to 40. In the time domain, each superframe includes 48 radio frames, that is, i is 48, each radio frame includes 8 time domain symbols, different time domain symbols in the radio frames may be configured as a C link symbol or a T link symbol, the C link symbol is used for data transmission of a C link method, the T link symbol is used for data transmission in a T link direction, the C link direction is a 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 a direction in which the first communication device sends data to the first control node or the second control node. The C-link symbol or the T-link symbol may be located in any position in the radio frame, for example, as shown in fig. 3, 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. Between the C-link symbol and the T-link symbol there is a Guard Period (Gap) symbol, which is typically used for transceive or transceive conversion.

In the short-range communication system in the vehicle, the subcarrier interval is 480kHz, one radio frame comprises 8 OFDM symbols, the time length is 20.833us, the time length of 48 radio frames is 1ms, and the time length corresponds to a superframe. In the 3GPP NR system, the length of one slot is 1ms for a subcarrier spacing of 15kHz, 0.5ms for a subcarrier spacing of 30kHz, and so on.

It should be noted that fig. 3 schematically illustrates the structure of the superframe and radio frame for easy understanding, but this should not limit the present application in any way, and the method in the present application is still applicable to other types of superframe and radio frame structures.

Wherein the resource allocated to the first system (i.e. the first set of subcarriers) is for use by a first control node in the first system and a first communication device in the first system. When a first control node and/or a first communication device in the first system needs to communicate, a first set of subcarriers may be occupied for data transmission. The resource allocated to the second system, i.e. the second set of sub-carriers, is for use by a second control node in the second system and a second communication device in the second system. When a second control node and/or a second communication device in the second system needs to communicate, the second set of subcarriers may be occupied for data transmission. It should be noted that the first control node and/or the first communication device may occupy the first subcarrier set to send data to the second control node, and the second control node may 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 to perform data transmission, and the device in the second system occupies the second subcarrier set to perform data transmission.

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 superframe is different from the transmission direction of the next superframe in the first system, the first subcarrier set is located in any Gap symbol in the superframe except the last Gap symbol of the last radio frame.

Specifically, when the time domain position corresponding to the first subcarrier set may be a Gap symbol in a radio frame, the first control node and/or the first communication device in the first system may perform data transmission in the C-link direction or the T-link direction on the subcarrier set of 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.

In a possible embodiment, in a case where the second system occupies the first set of subcarriers in part of or all of the superframes, the transmission direction of the first set of subcarriers is the same as or different from the transmission direction of the second set of subcarriers on a first symbol, and the first symbol is any OFDM symbol in a radio frame.

Wherein, in order to improve the utilization rate of the frequency domain resource, the second system may use the first set of subcarriers under certain conditions. When the second system may occupy the first set of subcarriers in part of or all of the superframes, the transmission direction of the first set of subcarriers may be the same as or different from the transmission direction of the second set of subcarriers, i.e., the transmission direction of the first set of subcarriers in each symbol in the radio frame may be the same as the configuration of the second system. For example, assume that the transmission method of the second subcarrier in the second system is as shown in fig. 3, that is, the transmission direction of the first 4 symbols of the radio 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 of the frequency domain positions corresponding to the first 4 symbols in the radio frame is the C link direction, and the transmission direction of the first subcarrier set of the frequency domain positions corresponding to the last four symbols in the radio frame is the T link direction, that is, the symbol ratio in the radio frame in the superframe occupied by the first system and the second system is the same.

For example, in an in-vehicle communication scenario, it is assumed that a first system is a PEPS subsystem, and a second system is a subsystem supporting in-vehicle voice and time-frequency services, in a state where a vehicle is not started, the PEPS subsystem occupies a first set of subcarriers, and a guard interval of at least G subcarriers exists between a frequency domain and a time-frequency resource occupied by the second system and the first set of subcarriers. When the vehicle is in the starting state, the PEPS subsystem is in the stop state, in which case the second subsystem may occupy the first set of subcarriers.

In an embodiment of the present application, a guard interval is included between the first set of subcarriers and the second set of subcarriers.

In order to reduce in-band leakage interference between different systems, a guard interval of G subcarriers may exist between a first subcarrier set occupied by a first system and a second subcarrier set occupied by a second system, and/or a guard interval of G subcarriers may exist between the first subcarrier set occupied by the first system and a subcarrier set occupied by other first systems, and/or a guard interval of G subcarriers may exist between the second subcarrier set occupied by the second system and a subcarrier set occupied by other first systems, and any system cannot occupy the guard interval of G subcarriers.

In one possible embodiment, the first set of subcarriers is contiguous with the second set of subcarriers in the frequency domain.

When the time that the first system occupies the first subcarrier set to send data is different from the time that the second system occupies the second subcarrier set to send data, in-band leakage cannot be caused between the first system and the second system, and at this time, the first subcarrier set and the second subcarrier set can be continuous on a frequency domain. For example, in an in-vehicle communication scenario, it is assumed that a first system is a PEPS subsystem, and a second system is a subsystem supporting in-vehicle voice and time-frequency services, and in a state where a vehicle is not started, the PEPS subsystem occupies a first subcarrier set, and the second system occupies a second subcarrier set; when the vehicle is in the starting state, the PEPS subsystem is in the stop working state, and in this case, the second subcarrier set and the first subcarrier set can be continuous in the frequency domain.

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, a 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 smaller than a preset threshold.

When the first system and the second system are close to each other in geographic location, 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 smaller than a preset threshold, the near-far effect caused by the first system and the second system is weak, and the second control node may configure or pre-configure the first subcarrier set and the second subcarrier set to be continuous in frequency domain.

For example, it is assumed that a first control node of a first system and a second control node of a second system are very close in geographical position, and the first control node in the first system occupies a first set of subcarriers in a frequency domain position corresponding to a C link symbol to transmit data in the C link direction, and the second control node in the second system occupies other sets of subcarriers in a frequency domain position corresponding to the C link symbol to transmit data in the C link direction. In this case, since the near-far effect caused by the fact that the transmission power of each subcarrier transmitted by the first control node and the second control node is received by the first communication device is close, no guard subcarrier may be left between the first set of subcarriers and the second set of subcarriers.

For example, assuming that a first control node of a first system and a second control node of a second system are very close in geographical location, a first communication device in the first system occupies a first set of subcarriers in a frequency domain location corresponding to a T-link symbol to transmit data in the T-link direction, and a second control node in the second system occupies other sets of subcarriers in a frequency domain location corresponding to a T-link symbol to transmit data in the T-link direction. In this case, since the near-far effect caused by the close signal power of the second control node and the first control node for receiving the first communication device in the first system is weak, no guard subcarrier may be left between the first subcarrier set and the second subcarrier set.

In this embodiment of the present application, the second control node obtains the location information of a first subcarrier set and/or the location information of a second subcarrier set, where 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 control node determines the location information of the first subcarrier set, so that effective resource coordination of the first system and the second system on the same carrier can be achieved, and interference between the systems is avoided.

Optionally, the time domain location information includes location information of the first set of subcarriers in a superframe.

Optionally, the location information further includes a number N of subcarriers in the first subcarrier set, where N is a positive integer.

Wherein the first communication device may determine the location information of the first set of subcarriers by preconfiguration, e.g., the first communication device may determine that the first set of subcarriers is located on the last 10 consecutive subcarriers of the superframe according to preconfiguration.

In some examples, the first communication device may receive first configuration information sent by a first control node in the first system, where the first configuration information may include the location information, and the first communication device may determine the location information of the first set of subcarriers according to the first configuration information. In some examples, a first communication device is receiving first configuration information transmitted by a first control node in a first system.

The first communication device may further receive first configuration information sent by a second control node in the second system, where 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 is receiving first configuration information sent by a first control node in the first system and a second control node in the second system, and the first communication device may determine the location information of the first set of subcarriers by the first configuration information sent by the first control node in the first system. In some examples, the first communication device may still determine the location information of the first set of subcarriers by preconfiguration upon receiving the first configuration information sent by the first control node in the first system and/or the second control node in the second system.

It should be noted that the method described above may also be applied to a second communication device in a second system. When the method is applied to the second communication device, the first control node in the method is the second control node.

It can be seen that, in this embodiment of the present application, a first communication device obtains location information of a first set of subcarriers, where the first set of subcarriers is used for communication in a first system, the first system includes the first communication device and a first control node, and determines a location of the first set of subcarriers according to the location information, where the location information includes at least one of: time domain position information of the first set of subcarriers and frequency domain position information of the first set of subcarriers. The time-frequency resource which can be used by the equipment of the first system is determined by the first communication equipment, so that the resource allocation of the first system is realized.

Referring to fig. 5, fig. 5 is a flowchart illustrating a resource allocation method according to an embodiment of the present invention, the method being applied to the application scenarios shown in fig. 1a to fig. 1c, and the wireless communication system shown in fig. 2. As shown in fig. 5, the resource allocation method includes the following steps.

In an embodiment of the present application, the first system includes a first control node and at least one first communication device, and the first control node may determine, by pre-configuration, that the first system occupies number N of subcarriers in the first set of subcarriers and frequency domain positions of the first set of subcarriers in a superframe.

Wherein the first control node may determine, by pre-configuration, that the first system occupies a particular set of subcarriers within the superframe, e.g., as shown in fig. 6a, the first system may occupy the first N consecutive subcarriers in the superframe. In the embodiment of the application, N is a positive integer less than or equal to 40.

It should be noted that the first subcarrier set may be any continuous N subcarriers in a superframe or any discontinuous N subcarriers in the superframe, which is not limited in the embodiment of the present application.

Optionally, the time domain location information includes location information of the first subcarrier set in a superframe.

In a possible embodiment, in a case that a part or all of the time domain positions corresponding to the first subcarrier set are the Gap symbols, the position information further includes the time domain positions of the Gap symbols.

For example, the first control node may determine, through preconfiguration, a set of subcarriers on all Gap symbols of all radio frames in a superframe that the first system occupies, as shown in fig. 6 b; in some examples, the first control node may determine, by pre-configuration, that the first system occupies a set of subcarriers on the first or second Gap symbol of all radio frames within the superframe, in some examples, the first control node may determine, by pre-configuration, that the first system occupies a set of subcarriers on all Gap symbols of the intra-superframe portion of radio frames, in some examples, the first control node may determine that the first system occupies a set of subcarriers on the first or second Gap symbol of the intra-superframe portion of radio frames. Further, the first system may occupy a part of subcarriers or all subcarriers of the Gap symbol corresponding to the frequency domain position.

In a possible embodiment, in a case that the time domain position part corresponding to the first subcarrier set is a C-link symbol or all C-link symbols, or the time domain position part corresponding to the first subcarrier set is a T-link symbol or all T-link symbols, the position information further includes a symbol position of the C-link symbol or the T-link symbol.

The first control node may determine, by pre-configuration, the number N of subcarriers in a first subcarrier set occupied by a first system in a superframe, the frequency domain position of the first subcarrier set, and the symbol position of the first subcarrier set corresponding to the time domain position. The symbol position may be a part of or all of the C-link symbols, or may be a part of or all of the T-link symbols.

Specifically, the C-link symbols or T-link symbols of the first system may occupy a particular set of subcarriers on a particular symbol within the superframe, e.g., as shown in fig. 6C, the C-link symbols of the first system occupy the first N consecutive subcarriers on all C-link symbols within the superframe. In some examples, the T-link symbols of the first system occupy the first N consecutive subcarriers on the partial C-link symbols within the superframe. In some examples, the T-link symbols of the first system occupy the first N consecutive subcarriers on some or all of the T-link symbols within the superframe. The N subcarriers within a superframe are used for transmission in only one direction of the first system, either the C-link method or the T-link direction.

In an embodiment of the present application, the method further includes: determining a transmission direction of the first set of subcarriers, the transmission direction comprising a C-link direction or a T-link direction.

The first control node in the first system may further determine a transmission direction of the first set of subcarriers in each radio frame in one period.

Optionally, the transmission directions of the first subcarrier sets of all radio frames of the superframe are both a C link direction or a T link direction.

Specifically, the first set of subcarriers in a superframe may be used for only one direction of transmission (C-link direction or T-link direction) of the first system, S superframes may constitute a period, the first P superframes in the period may be used for data transmission in the C-link direction, and the subsequent S-P superframes may be used for data transmission in the T-link direction. The value of P may be determined by a first control node in the first system. For example, as shown in fig. 6d, S =10,p =9, the first 9 superframes in the period may be used for data transmission in the C link direction, and the last superframe may be used for data transmission in the T link direction. In some examples, even superframes within an S period may be used for data transmission in the C-link direction and odd superframes may be used for data transmission in the T-link direction. In other examples, all superframes may be used for data transmission in the C-link direction or the T-link direction within the first system. Of course, the embodiments of the present application are not limited to other methods for determining the transmission direction.

Optionally, the transmission direction of the first subcarrier set on m radio frames in the superframe is the C link direction, the transmission direction of the subcarrier set on 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.

Specifically, the first subcarrier sets on different radio frames in a superframe may be used for different directions of transmission of the first system, for example, the first subcarrier sets in the first 24 radio frames in a superframe are used for data transmission in C-link direction, and the first subcarrier sets in the last 24 radio frames are used for data transmission in T-link direction.

Optionally, when the time domain position part corresponding to the first subcarrier set is the C link symbol, or all the C link symbols, the transmission direction of the first subcarrier set of all the superframes is a C link direction; and when the time domain position part corresponding to the first subcarrier set is the T link symbol or all the T link symbols, the transmission direction of the first subcarrier set of all the superframes is the T link direction.

Specifically, if the time domain position corresponding to the first subcarrier set is a C link symbol in a radio frame, the first subcarrier set in all superframes is used for data transmission in the C link direction; on the contrary, if the time domain position of the first subcarrier set is a T link symbol in a radio frame, the first subcarrier set in all superframes is only used for data transmission in the T link direction.

Optionally, when the time domain position corresponding to the first subcarrier set is the Gap symbol, the time length for transmitting the 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.

When the first control node transmits data on the Gap symbol, the first control node needs to generate an OFDM symbol with a time length of 64 × Ts, or an OFDM symbol with a time length of (64 + X) × Ts, where 64 × Ts is a data portion, X × Ts is a cyclic prefix, and X may be 5 or 14, ts = 1/(480000 × 64) seconds. In the embodiment of the present application, the time length of the Gap symbol is 44 × ts, i.e. L =44 × ts, and therefore, as shown in fig. 6e, only the last 44 × ts of the OFDM symbol is transmitted on the Gap symbol.

Optionally, the OFDM symbols are distributed at intervals corresponding to subcarriers in a subcarrier set carrying valid data in a frequency domain position.

Specifically, as shown in fig. 6e, when the first control node transmits data on the Gap symbol, the modulated OFDM symbol may be mapped to even subcarriers of the superframe, and an OFDM symbol with a time length of 64 × Ts is generated, or an OFDM symbol with a time length of (64 + x) × Ts is generated, and then only the last 44 × Ts of the OFDM symbol is transmitted on the Gap symbol. In some examples, when the first control node transmits data on a Gap symbol, the modulated OFDM symbol may be mapped to odd subcarriers of a superframe and an OFDM symbol having a time length of 64 × Ts is generated, or an OFDM symbol having a time length of (64 + x) × Ts is generated, and then only the last 44 × Ts of the OFDM symbol is transmitted on the Gap symbol.

In one possible embodiment, the method further comprises: sending second configuration information to the first communication device, where the second configuration information is used to determine a transmission direction of the first set of subcarriers in the superframe.

S530, the first communication device receives the first configuration information from the first control node, and determines the location information of the first subcarrier set based on the first configuration information.

For a first communication device in a first system, the number N of subcarriers in a first subcarrier set in a superframe and the frequency domain position of the first subcarrier set can be determined by receiving first configuration information sent from a first control node in the first system, so that data can be sent or received at the frequency domain position of the corresponding first subcarrier set.

In a possible embodiment, when part or all of the time domain positions corresponding to the first set of subcarriers are the Gap symbols, the position information further includes the time domain positions of the Gap symbols.

After receiving the first configuration information sent by the first control node, the first communication device may determine a time domain position of a Gap symbol available to the first system, a number N of subcarriers in a first subcarrier set occupied by each Gap symbol, and a frequency domain position of the first subcarrier set. As shown in fig. 6b, according to the first configuration information, the first communication device may determine that the first system may occupy all Gap symbols of a part of radio frames in a superframe. In some examples, the first system may occupy a portion of Gap symbols of a portion of radio frames within the superframe, or may occupy a portion of Gap symbols of all radio frames within the superframe, or may occupy all of Gap symbols of all radio frames within the superframe. The first system may occupy a part of subcarriers or all subcarriers of the Gap symbol corresponding to the frequency domain position.

After receiving the first configuration information sent by the first control node, the first communication device may determine a symbol position of the first system in a time domain for a C-link direction or a symbol position of the first system in a T-link direction, and a number N of subcarriers in the first subcarrier set and a frequency domain position of the first subcarrier set in a frequency domain. As shown in fig. 6C, according to the first configuration information, the first communication device may determine that the first system may occupy the first N consecutive subcarriers of the frequency domain positions corresponding to all C-link symbols of all radio frames in the superframe.

Wherein the first communication device may receive second configuration information sent from the first control node to determine a transmission direction of the first set of subcarriers. Specifically, the first communication device may determine, according to the second configuration information, that the first set of subcarriers in one superframe of the first system may be used for transmission in only one direction of the first system, or determine that the first set of subcarriers on different subcarriers in one superframe of the first system may be used for transmission in different directions of the first system.

Specifically, the first communication device may determine that all superframes in the first system are used for the C-link or the T-link according to the second configuration information. For example, the time domain positions corresponding to the first set of subcarriers may be located on all C-link symbols in a superframe, or the time domain positions corresponding to the first set of subcarriers may be located on a part of C-link symbols of a specific radio frame in a superframe; or the time domain position corresponding to the first subcarrier set is positioned on all C link symbols of a part of radio frames in a superframe.

Further, in a case that the time domain position corresponding to the first subcarrier set is the Gap symbol, the first communication device may determine, according to the second configuration information, a transmission direction of the Gap symbol available to the first subsystem in each superframe. For example, the first communication device may determine, according to the second configuration information, that the transmission methods of the Gap symbols available to the first system in all superframes are all C-link directions.

In some examples, the first communication device may also determine the transmission direction of the first set of subcarriers in each superframe by preconfiguration, or after receiving the second configuration information, the first communication device may still determine the transmission direction of the first set of subcarriers in each superframe by preconfiguration. For example, the first communication device may determine, according to the preconfiguration, that all superframes in the first system are used for the C link, or the first communication device may determine, according to the preconfiguration, that all transmission methods of Gap symbols available to the first system in all superframes are in the C link direction.
