As an example, the first communication system in the embodiments of the present disclosure is a 6G communication system, and the second communication system is a 5G communication system.

The network architecture of the communication network in embodiments of the present disclosure, including but not limited to third generation (3th generation,3G), 4g,5g, and future mobile communication networks, may include at least a first node and a second node. In this example, the first node may be a terminal-side device (e.g., including but not limited to a terminal) and the second node may be a network-side device (e.g., including but not limited to a base station).

An exemplary embodiment, taking a first node as a terminal and a second node as a base station, as shown in fig. 1, is a schematic diagram of a first communication system provided in an embodiment of the disclosure. The first communication system includes a terminal 110 and a base station 120. Wherein the terminal 110 is communicatively coupled to the base station 120.

In some embodiments, the base station 120 may be one or more, and the terminal 110 may be one or more, and the embodiments of the present disclosure are not limited in number.

In some embodiments, the base station 120 may provide different standards of network services for the terminal 110. For example, the base station 120 may provide a long term evolution (long term evolutio n, LTE) network service, a new radio, NR, network service, etc. to the terminal 110.

The terminal 110 is configured to determine a first transmission resource based on the signaling indication of the base station 120, and communicate with the base station 120 based on the first transmission resource. Wherein the first transmission resource and the second transmission resource of the second communication system share a shared spectrum.

The base station 120 may dynamically allocate spectrum resources (i.e., first transmission resources) to the terminal 110 and communicate with the terminal 110 based on the first transmission resources.

In some embodiments, the base station 120 may send a signaling indication to the terminal to instruct the terminal 110 to determine a time slot/symbol occupied by the first transmission resource, a time slot/symbol to be avoided by the first transmission resource, a frequency domain allocation ratio of the first transmission resource and the second transmission resource on the shared spectrum, and so on.

In some embodiments, the base station 120 may also send an indication to the terminal 110 regarding the cell configuration, such that the terminal 110 reuses the cell configuration of the second communication system based on the signaling indication; or newly adding the cell configuration of the first communication system on the basis of the cell configuration of the second communication system; or using a separate cell configuration.

It should be noted that, the above scenario is for more clearly describing the technical solution of the embodiments of the present disclosure, and does not constitute a limitation to the technical solution provided by the embodiments of the present disclosure, and those skilled in the art can know that, with the evolution of the system architecture and the appearance of the new service scenario, the technical solution provided by the embodiments of the present disclosure is equally applicable to similar technical problems.

In communication systems, communication technology is rapidly evolving and will be widely used due to the ever-increasing data transmission requirements and the need for higher transmission rates, lower transmission delays, more reliable connections. As a next generation mobile communication technology, the 6G communication technology is expected to provide a higher data transmission rate, a lower transmission delay, and a wider coverage. As a 6G communication system requires a wider spectrum bandwidth and a higher transmission rate, the demand for spectrum resources is also greater. However, with the development of communication systems and the increasing demand for wireless communication, spectrum resources on a global scale are increasingly strained, which may present challenges for the deployment and development of 6G communication systems.

The traditional techniques such as multi-system compatibility and dynamic spectrum sharing play an important role in the smooth evolution from the 4G communication system to the 5G communication system, and ensure the deployment and development of the 5G communication system. Similarly, 6G communication systems will also co-exist with and share spectrum resources of other communication systems for a long period of time in the future. Therefore, the compatibility of the 5G communication system and the 6G communication system is solved, the 6G communication system is ensured to smoothly share the spectrum resources of other communication systems, the deployment and development of the 6G communication system are ensured, and the smooth evolution from the 5G communication system to the 6G communication system is realized.

In view of the foregoing, referring to fig. 2, a flowchart of a wireless communication method according to an embodiment of the disclosure is provided. As shown in fig. 2, the wireless communication method provided in the embodiment of the present disclosure is applied to a first node, and includes the following steps:

S101, determining a first transmission resource of a first communication system.

Wherein the first transmission resource and the second transmission resource of the second communication system share a shared spectrum.

In some embodiments, the first transmission resource is used for communication between a first node (e.g., terminal) and a second node (e.g., base station) in the first communication system. The second transmission resource is used for communication by a communication node in the second communication system.

In some embodiments, the first transmission resource and the second transmission resource do not overlap.

As one example, the first transmission resource and the second transmission resource share a shared spectrum in a time division manner. Illustratively, as shown in fig. 3, the first transmission resource and the second transmission resource are time-divided on the shared spectrum, and the first transmission resource uses all the spectrum during the period of t1-t 2.

As another example, the first transmission resource and the second transmission resource share a shared spectrum in a frequency division manner. Illustratively, in the shared spectrum shown in fig. 4, the first transmission resource and the second transmission resource occupy different frequency domains on the shared spectrum during the period of time t1-t 2. Furthermore, as shown in fig. 4, the first communication system may occupy other frequency domain resources on the frequency spectrum in addition to the shared spectrum (i.e., if the first communication system is in a frequency division duplex (frequency division duplex, fdd) mode, the first communication system may occupy a frequency band at other frequency band positions than the frequency band occupied by the shared spectrum).

In some embodiments, the first communication system may use a plurality of frequency bands, where the plurality of frequency bands includes a frequency band in which the shared spectrum is located.

In some embodiments, if the second communication system employs a time division duplex (time division du plex, TDD) mode, for example, the second communication system uses an N78 band (or an N79 band), then the uplink and downlink transmissions in the second communication system share the N78 band in a time division manner in the spectrum resource. At this time, the first communication system also adopts TDD mode, that is, uplink transmission and downlink transmission in the first communication system share the N78 frequency band.

In some embodiments, if the second communication system adopts the FDD mode, the uplink transmission and the downlink transmission in the second communication system adopt different frequency bands. For example, in the second communication system, the frequency band used for uplink transmission is 700MHz, and the frequency band used for downlink transmission is 800 MHz. At this time, the first communication system also adopts the FDD mode, that is, in the first communication system, uplink transmission and downlink transmission adopt different frequency bands. The frequency band used by the uplink transmission of the first communication system is the same as the frequency band used by the uplink transmission of the second communication system; or the frequency band used by the downlink transmission of the first communication system is the same as the frequency band used by the downlink transmission of the second communication system.

It will be appreciated that if the first communication system adopts a different mode of operation than the second communication system (e.g., the first communication system adopts TDD mode and the second communication system adopts FDD mode), it may result in waste of frequency band resources or frequency interference. Therefore, in order to maximally utilize the frequency band resources and avoid spectrum conflicts, in the embodiments of the present disclosure, the first communication system and the second communication system adopt the same working mode, so as to ensure that the two systems can co-exist in a coordinated manner on the shared spectrum and effectively utilize the resources of the shared spectrum, thereby reducing unnecessary interference.

S102, communicating with a second node in the first communication system based on the first transmission resource.

In some embodiments, after determining the first transmission resource, the first node may establish a connection with and communicate with the second node based on the location of the first transmission resource on the shared spectrum.

It should be noted that, when the first node and the second node communicate, data transmission may be unidirectional or bidirectional, which is not limited by the embodiments of the present disclosure.

Moreover, the first transmission resource shares the shared spectrum with the second transmission resource of the second communication system, so that the available or empty resources in the shared spectrum can be effectively utilized, the utilization efficiency of the shared spectrum is improved, the resources of the shared spectrum are utilized to the maximum extent, and the waste of the resources is avoided.

In some embodiments, the first transmission resource and the second transmission resource share a shared spectrum in a time division manner, the method further comprising: a first signaling is received.

Wherein the first signaling is used to indicate a time slot occupied by the first transmission resource.

In some embodiments, the time slot occupied by the first transmission resource comprises at least one of: a first type of time slot, a second type of time slot. Wherein all symbols on the first type of time slot are used for transmitting signals of the first communication system. Illustratively, as shown in fig. 5, the time slots occupied by the shaded portion of the first type of time slots are first type of time slots in which all symbols are used to transmit signals of the first communication system. And on that time slot there is no transmission of a signal or channel of the second communication system.

Part of the symbols on the second type of time slot are used for transmitting signals of the first communication system, and the other part of the symbols are used for transmitting signals of other communication systems. Illustratively, as shown in fig. 6, on the second type of slot, the symbols of the shaded portion are used for transmitting signals of the first communication system, and the symbols other than the shaded portion symbols are used for transmitting signals of the other communication systems.

It can be appreciated that, considering that there may be symbols occupied by the second communication system in the shared spectrum, in the method provided by the embodiment of the present disclosure, the first communication system occupies only a part of symbols on the second type of time slot, so that interference to the second transmission resource in the second communication system can be avoided.

In some embodiments, the second type of time slot satisfies at least one of the following a-h:

a. the second type of time slot includes symbols for transmitting a common signal of the second communication system. The common signal may be, for example, a synchronization signal block (synchronization signal block, ssb), a Repetition and Spreading (RS) signal.

B. The second type of time slot includes symbols for transmitting a control channel of the second communication system. Illustratively, the second type of slot includes symbols for transmitting a physical downlink control channel (physical downlink control channel, PDCCH) of the second communication system.

C. The second type of slot includes symbols for transmitting demodulation reference signals (dem odulation REFERENCE SIGNAL, DMRS) of the second communication system.

D. The second type of time slot includes symbols for transmitting a shared channel of the first communication system. Exemplary shared channels of the first communication system include a physical downlink shared channel (physical downlink SHARED CHANNEL, PDSCH) of the first communication system, and a Physical Uplink Shared Channel (PUSCH) of the first communication system.

In some embodiments, if the first node supports the first communication system and the second communication system, and the first communication system and the second communication system may be time division multiplexed at the symbol level, the shared channel of the first communication system may occupy some specific symbols, such as the 4 th-14 th symbols in the second type slot. That is, in the second type of time slot, the shared channel of the first communication system may transmit data on these symbols. Wherein the configuration parameters of the second type of time slots are configured based on the subcarrier spacing and the frame structure of the second communication system.

It can be appreciated that the reason why the shared channel of the first communication system occupies only some specific symbols, but does not occupy other symbols in the second type slot is to avoid data transmission on the symbol occupied by the second transmission resource and the symbol occupied by the cell-specific reference signal (cell-SPECIFIC REFERENCE SIGNALS, CRS), so as to avoid mutual interference and collision between the first transmission resource and the second transmission resource.

E. The second type of time slot does not include symbols for transmitting a shared channel of the second communication system. The shared channel of the second communication system does not include a PDSCH channel of the second communication system, a PUSCH channel of the second communication system, for example.

F. The second type of slot includes symbols for transmitting cell reference signals (com mon reference symbol, CRS) of the third communication system. The third communication system may be a long term evolution (long term evolution, LTE) system in a 4G network, for example.

G. The second type of slot does not include symbols for transmitting a control channel of the second communication system. Illustratively, the second type of slot does not include symbols for transmitting a physical uplink control channel (physical uplink control channel, PUCCH) of the second communication system.

H. the second type of time slot does not include a random access channel occasion (rando M ACCESS CHANNEL occasin, RO) of the second communication system.

In some embodiments, where the time slot occupied by the first transmission resource comprises a second type of time slot, the first signaling is further used to indicate a symbol in the second type of time slot for transmitting a signal of the first communication system. Illustratively, the first signaling indicates that the symbols in the second type of time slot used to transmit the signal of the first communication system are the 4 th-14 th symbols.

In some embodiments, the first signaling is carried in broadcast information of the second communication system; or the first signaling is carried in control signaling of the first communication system.

As an example, the second node carries the first signaling in broadcast information of the second communication system, which broadcast information may indicate whether the first transmission resource of the first communication system occupies a time slot in the shared spectrum. Further, the second node may further indicate, through broadcast information of the second communication system, a type of a time slot occupied by the first transmission resource, for example, indicate that the time slot occupied by the first transmission resource is a first type time slot and/or a second type time slot.

In some embodiments, if the first signaling is carried in the broadcast information of the second communication system, the signal/channel (including uplink signal, downlink signal, uplink channel and downlink channel) of the second communication system is not transmitted in other time slots or subframes occupied by the second communication system except for the time slot or subframe in which the broadcast information is located.

As another example, the second node carries the first signaling in control signaling (e.g., a Media Access Control (MAC) Control Element (CE)) of the first communication system, which may indicate a type of time slot occupied by the first transmission resource, e.g., indicate that the time slot occupied by the first transmission resource is a first type of time slot and/or a second type of time slot. Further, the second node may also indicate, through control signaling, a symbol occupied by the first transmission resource in a certain first type of slot.

As yet another example, the second node may also indicate a time slot occupied by the first transmission resource and a type of the time slot in the PDCCH of the first communication system. Further, the second node may also indicate, through the PDCCH of the first communication system, a symbol occupied by the first transmission resource in a certain first type of slot.

It can be understood that in the method provided by the embodiment of the present disclosure, the first signaling is carried in the broadcast information of the second communication system or in the control signaling of the first communication system, and additional information can be carried in the existing broadcast information or control signaling, so that the requirement for additional spectrum resources is reduced, the resource waste caused by opening up a new channel for a small amount of signaling data is avoided, and the operation cost of the communication system is reduced.

In some embodiments, the first transmission resource and the second transmission resource share a shared spectrum in a frequency division manner, the method further comprising: a second signaling is received.

The second signaling is used for indicating the frequency domain allocation proportion of the first transmission resource and the second transmission resource on the shared frequency spectrum.

For example, if the frequency domain resources of 100MHz are shared, the second signaling indicates that the first transmission resource and the second transmission resource occupy half of the frequency domain resources of 100MHz in the time slot and the second transmission resource occupies the other half of the frequency domain resources of 100MHz in the time slot when the frequency domain allocation ratio is 1:1. In addition, the first communication system may also use other spectrum resources besides the shared spectrum, for example, the TDD sub-band of the first communication system uses 200MHz frequency domain resources on some timeslots.

In some embodiments, the shared spectrum is used as a secondary carrier of the first communication system, and the second signaling is carried in signaling of a primary carrier of the first communication system; or the shared spectrum is used as a main carrier of the first communication system, and the second signaling is carried in broadcast information of the second communication system.

As an example, if the shared spectrum is used as a secondary carrier of the first communication system, the second signaling is carried in signaling (e.g., downlink control information (downli nk control information, DCI)) of the primary carrier of the first communication system. The second node may indicate a frequency domain allocation ratio of the first transmission resource and the second transmission resource on the shared spectrum based on the DCI; or the second node may further instruct to allocate frequency domain resources for the first transmission resource and the second transmission resource in an order of low to high numbers of physical resource blocks (physical resource block, PRBs) based on the DCI.

As another example, the second node may indicate a frequency domain allocation ratio of the first transmission resource and the second transmission resource on the shared spectrum based on the new MAC CE (i.e., a MAC CE different from the second communication system); or the second node may further instruct to allocate frequency domain resources for the first transmission resource and the second transmission resource in order of the number of PR B from low to high based on the MAC CE.

In some embodiments, the second node transmits the second signaling to the first node at a time granularity of 1ms or 1 slot.

It can be understood that in the method provided by the embodiment of the present disclosure, the shared spectrum is used as the secondary carrier of the first communication system, so that additional spectrum resources can be added on the premise of not affecting the normal communication service of the primary carrier, thereby improving the overall communication capacity of the first communication system. And the second signaling is carried in the signaling of the main carrier, so that the priority transmission and processing of the key control information can be ensured, and meanwhile, the additional data stream is transmitted through the auxiliary carrier, so that more efficient data management and distribution are realized.

In contrast, if the shared spectrum is used as the primary carrier, the second signaling is carried in the broadcast information of the second communication system, so that the first communication system and the second communication system share the signaling information, redundancy of signaling transmission is reduced, and better fusion and cooperation between different communication systems are realized.

In some embodiments, the cell configuration of the first communication system is the same as the cell configuration of the second communication system over the shared spectrum. That is, the default first communication system and the cell configuration are the same as the cell configuration of the second communication system over the shared spectrum.

In some embodiments, the above method further comprises: third signaling is received.

Wherein the third signaling is used to instruct the cell configuration of the first communication system to multiplex the cell configuration of the second communication system.

In some embodiments, the shared spectrum is used as a secondary carrier of the first communication system, and the third signaling is carried in a signaling of a primary carrier of the first communication system; or the shared spectrum is used as a main carrier of the first communication system, and the third signaling is carried in broadcast information of the second communication system. For example, if the shared spectrum is used as a secondary carrier of the first communication system, the third signaling may be carried in radio resource control (radio resource control, RRC) signaling of the primary carrier of the first communication system.

In some embodiments, the third signaling includes a bit, and the first node determines whether the cell configuration of the first communication system multiplexes the cell configuration of the second communication system based on a value of the bit. Illustratively, a value of 1 indicates that the cell configuration of the first communication system multiplexes the cell configuration of the second communication system, and a value of 0 indicates that the cell configuration of the first communication system does not multiplex the cell configuration of the second communication system.

For example, if the bit in the third signaling has a value of 1, the first node determines that the cell configuration of the first communication system multiplexes the cell configuration of the second communication system (e.g., TDD Uplink (UL) -Downlink (DL) configuration, subcarrier spacing configuration, etc.). As one example, the TDD UL-DL configuration of the first communication system is the same as the TDD UL-DL configuration of the second communication system, and the time slot occupied by the first transmission resource starts from the beginning of the configuration period of the TDD UL-DL. For example, a slot occupied by the first transmission resource is allocated for the first transmission resource at the beginning of a TDD UL-DL configuration period of 2.5 ms or 5 ms. As shown in fig. 7, the TDD UL-DL configuration period of the second transmission resource in the second communication system is DDDUU, the time slot occupied by the first transmission resource starts from the start of one period, and the sequence of symbols in the time slot is DDDUU. As another example, the TDD UL-DL configuration of the first communication system and the TDD UL-DL configuration of the second communication system may also be different, i.e. the time slot occupied by the first transmission resource may start with any time slot as the start point. Furthermore, as shown in fig. 7, the first communication system may occupy other frequency domain resources on the frequency spectrum in addition to the shared spectrum (i.e., if the first communication system is FDD, the first communication system may occupy a frequency band at other frequency band positions than the frequency band occupied by the shared spectrum).

In some embodiments, the cell configuration of the first communication system is independent of the cell configuration of the second communication system over the shared spectrum.

For example, if the first transmission resource and the second transmission resource are time-divided over a shared spectrum, or the time slot occupied by the first transmission resource is a first type of time slot (the first transmission resource uses the entire spectrum resource over the first type of time slot), the first communication system may use an independent cell configuration (e.g., SSB configuration, RS configuration). For example, if the shared spectrum is used as a secondary carrier of the first communication system, the second node instructs the first communication system to use an independent cell configuration through signaling of the primary carrier of the first communication system.

For SSB configuration, in some embodiments, the synchronization signal block SSB configuration of the first communication system is independent of the SSB configuration of the second communication system over the shared spectrum.

In some embodiments, as shown in fig. 8, the synchronization signal block SSB of the first communication system occupies a different time-frequency resource location than the SSB of the second communication system.

In some embodiments, the cell configuration of the first communication may add a new cell configuration on the basis of the cell configuration of the second communication system in addition to multiplexing the cell configuration of the second communication system independently of the cell configuration of the second communication system in addition to the same cell configuration of the second communication system. For example, a new SSB (e.g., new structure SSB) is configured on the basis of the SSB of the second communication system. Illustratively, the new structure SSB occupies a different time-frequency resource location than the SSB of the second communication system. At this time, the first communication system may transmit data using the SSB of the second communication system and the SSB of the new structure.

In some embodiments, if the first communication system and the second communication system use the same SB, e.g., SSB index (index) 1, the first communication system and the second communication system should send the same maximum burst interval (maximum burst interval, MBI) information on the SB, and the first signaling mentioned in the above disclosed embodiments may be carried in a broadcast message in the SSB.

In some embodiments, one SSB comprises at least one of: primary synchronization signal (pri mary synchronization signal, PSS), secondary synchronization signal SSS (secondary sync hronization signal, SSS) and physical broadcast channel (physical broadcast channel, PBCH). For example, taking SSB with a period of 20ms as an example, the transmission mode of SSB at each symbol position is as follows: the 1 st symbol is null, the 2 nd to 5 th symbols contain PSS and SSS, the 6 th to 7 th symbols are null, and the 8 th to 11 th symbols contain PBCH.

In some embodiments, if each SSB includes only two symbols, for example, every two SSBs are separated by 2 symbols.

In some embodiments, the SSB beam is received at a time domain location of the SSB of the first node second communication system over the shared spectrum, and the SSB beam may also be received at a time domain location of the SSB of the first communication system.

It will be appreciated that in the method provided by the embodiment of the present disclosure, on the shared spectrum, the first node may configure a specific SSB index to receive an SSB beam at a specific location, that is, the first node may choose to receive the beam at the specific SSB index location, where the beam may include a legacy SSB and possibly other new SSB beams, so that the first node may communicate based on the first communication system or the second communication system, which helps to provide better compatibility.

Further, during downlink beam scanning, the SSB index includes both SSB index of the first communication system and SSB index of the second communication system. The first node may find the optimal receive beam by scanning the entire SSB index range. Similarly, a similar approach can be taken in the uplink beam scanning.

For RS configuration, the first communication system and the second communication system may take different configurations to share and manage RSs. For example, in TDD mode, the first communication system and the second communication system may be allowed to use the same RS configuration; in FDD (frequency division duplex) mode, the resources of the RS may be allocated to the first communication system and the second communication system according to different frequency bands and bandwidth configurations. For example, for the first communication system, RS resources suitable for the bandwidth of the first communication system may be configured; for the second communication system, RS resources suitable for the bandwidth of the first communication system may be configured.

It can be understood that the first communication system and the second communication system can flexibly configure RS resources according to needs to realize cooperative work between different systems, ensure normal communication of the device in different environments, further improve efficiency and performance of the systems, and promote smooth transition between different communication systems.

In some embodiments, the above method further comprises: fourth signaling is received. Wherein the fourth signaling is used to indicate the third transmission resource.

In some embodiments, the first node is not supported for communication with the second node on the third transmission resource, i.e., the first node cannot communicate with the second node using the third transmission resource.

In some embodiments, the third transmission resource comprises at least one of: a time slot that does not support communication between the first node and the second node, and a symbol that does not support communication between the first node and the second node. The third transmission resource may be, for example, a time slot, symbol, etc., that has been occupied by the second transmission resource.

In some embodiments, the above method further comprises: fifth signaling is received. Wherein the fifth signaling is for indicating at least one of: the time slot to be avoided by the first transmission resource and the symbol to be avoided by the first transmission resource. For example, the fifth signaling may indicate that the first transmission resource is within one or more time slots, avoiding a time slot, channel, or symbol occupied by the second transmission resource. Or instruct the first transmission resource to avoid the time slot, channel, or symbol occupied by the second transmission resource for one or more periods.

In some embodiments, the second node may also send a signaling indication to the first node indicating that the first transmission resource avoiding portion RB of the first node. For example, the first transmission resource is instructed to avoid 20 RBs and 4 consecutive symbols occupied by the SB. For example, as shown in fig. 9, the first transmission resource may avoid RBs occupied by the SSB in the frequency domain; the first transmission resource may avoid 4 consecutive symbols among symbols occupied by the SSB in the time domain.

In some embodiments, if the signal or channel of the second communication system is already configured in the shared spectrum, the first transmission resource of the first node may further avoid the signal or channel of the second communication system based on the signaling indication of the second node when the shared channel of the first communication system is mapped on the RE.

In some embodiments, the above method further comprises: capability information is sent.

The capability information is used for indicating whether the first node supports rate matching while avoiding the second transmission resource when performing resource element mapping.

In some embodiments, the second node may determine the content of a time domain resource allocation table (time domain resource allocation table, TDRA table) of the first communication system based on the capability information of the first node. Wherein TDRA table are used to indicate the starting symbol, the number of symbols available or the length of the symbols available, etc. of the first communication system over a slot.

In some embodiments TDRA table may also indicate the location of the collision symbol. In the collision symbol, the first communication system cannot perform data transmission, for example, cannot perform PDSC H transmission or PUSCH transmission.

As an example, based on the capability information of the first node, if the first node does not support rate matching while avoiding the second transmission resource when performing resource element mapping, the second node determines that TDRA table of the first communication system employs TDRA table of the second communication system, and performs a puncturing operation after performing RE mapping.

As another example, if the first node supports rate matching while avoiding the second transmission resource when performing resource element mapping, the second node determines that TDRA table of the first communication system is independent of TDRA table of the second communication system, i.e., the first communication system employs a new TDR a table.

Illustratively, table 1 below, one example of a new TDRA table is employed for the first communication system.

Table 1TDRA table

Wherein a, b, x1, x2, etc. are natural numbers.

Illustratively, as shown in the first row of table 1, the first communication system starts with the a-th symbol as a start symbol in one slot, the available symbol length is less than x1, and the x 1-th symbol is a collision symbol. The first communication system may further use the x1+b symbol as the second starting symbol in one slot, and the available symbol length is not limited.

It should be noted that table 1 above is only one example given in the embodiment of the disclosure, and in actual implementation, there may be more or less parameters in TDRA table than table 1 above, which is not limited in the embodiment of the disclosure.

Illustratively, another example of using the new TDRA table for the first communication system is shown in table 2 below.

Table 2TDRA table

row index	start symbol	length	collided symbol
				1	a1	L	x1
2	a2	L	x1,x2
				3	a3	L	x1,x2,x3

Wherein a1, a2, a3, a4, x1, x2, x3, x4, L, etc. are natural numbers.

Illustratively, as shown in the first row of table 2, the first communication system starts with the a1 st symbol as a starting symbol in one slot, the available symbol length is L (e.g., the length for transmitting PDSCH/PUSCH is L symbols), and the L symbols do not include collision symbols. Meanwhile, the x1 st symbol is a collision symbol.

It should be noted that table 2 above is only one example given in the embodiment of the disclosure, and in actual implementation, there may be more or less parameters in TDRA table than table 2 above, which is not limited by the embodiment of the disclosure.

Illustratively, as shown in Table 3 below, a further example of the new TDRA table is employed for the first communication system.

Table 3TDRA table

row index	start symbol	length	collided symbol
				1	0	11	4

For specific meanings of table 3, reference may be made to the examples in table 1 and table 2, and the disclosure is not repeated here.

In some embodiments, as shown in table 1, table 2, or table 3 above, row index=1 may represent symbol positions allocated for transmitting PDSCH or PUSCH as 1 st to 3 rd symbols, 5 th to 12 th symbols.

It should be noted that table 3 above is only one example given in the embodiment of the disclosure, and in actual implementation, there may be more or less parameters in TDRA table than table 3 above, which is not limited by the embodiment of the disclosure.

In some embodiments, the above method further comprises: and receiving a Physical Downlink Control Channel (PDCCH) sent by the second node on the first frequency spectrum.

The PDCCH is used for scheduling a first transmission resource on the shared spectrum; the first spectrum does not overlap with the shared spectrum.

In some embodiments, the first node may schedule PDCCH resources across carriers if the resources for PDCCH scheduling are insufficient. The PDCCH cross-carrier scheduling comprises two modes of main carrier scheduling and auxiliary carrier scheduling. In the primary carrier scheduling mode, the PDCCH may be transmitted using resources in the primary carrier or resources in the secondary carrier, and in the secondary carrier scheduling mode, the PDCCH may be transmitted using resources in the secondary carrier.

In some embodiments, the first transmission resource of the first communication system does not cover the control channel of the second transmission resource of the second communication system, and the first transmission resource may begin transmitting the PDCCH of the first communication system after the control domain of the second transmission resource (e.g., after the first three orthogonal frequency division multiplexing (orthogonal frequen cy division multiplexing, OFDM) symbols of the shared spectrum). That is, starting from the fourth OFDM symbol, a PDCCH of the first communication system may be transmitted.

In some embodiments, the first communication system may directly transmit the PDCCH of the first communication system using the third OFDM symbol and the fourth OFDM symbol in the shared spectrum.

It can be appreciated that in the method provided by the embodiment of the disclosure, the first transmission resource and the second transmission resource can provide a wider bandwidth for the first communication system (for example, the 6G communication system) by sharing the shared spectrum, so as to significantly increase the capacity of the first communication system. In addition, the shared spectrum provides more spectrum resources to the first communication system, which may improve the coverage and quality of the first communication system. Moreover, based on the shared spectrum, the first communication system and the second communication system can coexist and are not interfered with each other in communication, so that the deployment and development of the first communication system are ensured, and the system upgrading and the network upgrading are facilitated.
