[0044] For the purposes of the present application, the technical solutions and advantages will be described in further detail below with reference to the drawings.

[0045] The network architecture and service scenarios described in the embodiments of the present application are used to more clearly illustrate the technical solutions of the embodiments of the present application, and do not constitute a limitation on the technical solutions provided by the embodiments of the present application. It can be known by those skilled in the art that, as the network architecture evolves and new service scenarios appear, the technical solutions provided by the embodiments of the present application are also applicable to similar technical problems.

[0046] The technical solutions of the embodiments of the present application can be applied to various communication systems, such as a Global System of Mobile communication (GSM) system, a Code Division Multiple Access (CDMA) system, a Wideband Code Division Multiple Access (WCDMA) system, a General Packet Radio Service (GPRS), a Long Term Evolution (LTE) system, an Advanced long term evolution (LTE-A) system, a New Radio (NR) system, an evolved system of the NR system, an LTE-based access to unlicensed spectrum (LTE-U) system, an NR-based access to unlicensed spectrum (NR-U) system, a non-terrestrial communication network system, a Universal Mobile Telecommunication System (UMTS), a Wireless Local Area Networks (WLAN), a Wireless Fidelity (WiFi), a 5th-Generation (5G) system, a 6th-Generation (6G) system, or other communication systems.

[0047] Generally, the traditional communication system supports a limited number of connections and is easy to implement. However, with the development of communication technology, the mobile communication system will not only support traditional communication, but also support, for example, Device to Device (D2D) communication, Machine to Machine (M2M) communication, Machine Type Communication (MTC), Vehicle to Vehicle (V2V) communication, or Vehicle to everything (V2X) communication, and the like. The embodiments of the present application can also be applied to these communication systems.

[0048] The communication system in the embodiments of the present application can be applied to a carrier aggregation (CA) scenario, a dual connectivity (DC) scenario, and a standalone (SA) network deployment scenario.

[0049] The communication system in the embodiments of the present application can be applied to unlicensed spectrum, which can also be considered as shared spectrum. Alternatively, the communication system in the embodiments of the present application can also be applied to licensed spectrum, which can also be considered as non-shared spectrum.

[0050] Before introducing the technical solutions of the present application, some related technical knowledge involved in the present application will be introduced and explained. The following related technologies can be combined with the technical solutions of the embodiments of the present application in any way, and all belong to the protection scope of the embodiments of the present application. The embodiments of the present application include at least part of the following contents.

[0051] 1. Network scenario

[0052] The communication system scenario includes a non-terrestrial communication network (NTN) system and a terrestrial network (TN) system. The NTN generally adopts a satellite communication mode to provide communication services to ground users. The NTN system currently includes an NR-NTN and an IoT-NTN (Internet of Things NTN) system, and may further include other NTN systems in the future.

[0053] For example, FIG. 1 is a schematic diagram of an architecture of a communication system according to an embodiment of the present application. As shown in FIG. 1, the communication system 100 can include a network device 110, which can be a device communicating with a terminal device 120. The network device 110 can provide communication coverage for a specific geographic area and can communicate with terminal devices located within the coverage area.

[0054] For example, FIG. 1 is a schematic diagram of an architecture of a communication system according to an embodiment of the present application. As shown in FIG. 1, the communication system 100 can include a network device 110, which can be a device communicating with a terminal device 120. The network device 110 can provide communication coverage for a specific geographic area and can communicate with terminal devices located within the coverage area.

[0055] For example, FIG. 2 is a schematic diagram of an architecture of a communication system according to another embodiment of the present application. As shown in FIG. 2, the communication system can include a terminal device 201 and a satellite 202, and the terminal device 201 and the satellite 202 can communicate wirelessly. The network formed by the terminal device 201 and the satellite 202 can also be referred to as an NTN. In the architecture of the communication system shown in FIG. 2, the satellite 202 can have the function of a base station, and the terminal device 201 and the satellite 202 can communicate directly. In this system architecture, the satellite 202 can be referred to as a network device. In some embodiments of the present application, the communication system can include multiple satellites 202, and each network satellite 202 can include other numbers of terminal devices within its coverage area, which are not limited in the embodiments of the present application.

[0056] For example, FIG. 3 is a schematic diagram of an architecture of a communication system according to another embodiment of the present application. As shown in FIG. 3, the communication system includes a terminal device 301, a satellite 302, and a base station 303, and the terminal device 301 and the satellite 302 can communicate wirelessly, and the satellite 302 and the base station 303 can communicate. The network formed by the terminal device 301, the satellite 302, and the base station 303 can also be referred to as an NTN. In the architecture of the communication system shown in FIG. 3, the satellite 302 can not have the function of a base station, and the communication between the terminal device 301 and the base station 303 needs to be relayed through the satellite 302. In this system architecture, the base station 303 can be referred to as a network device. In some embodiments of the present application, the communication system can include multiple base stations 303, each base station 303 can communicate with one or more satellites 302, and each satellite 302 can include other numbers of terminal devices within its coverage area, which are not limited in the embodiments of the present application.

[0057] In the future evolution of communication systems such as B5G (Beyond 5G) or 6G, distributed multiple-input multiple-output (Distributed MIMO, also known as distributed antenna system) scenarios and / or massive multiple-input multiple-output (Massive MIMO, also known as massive antenna matrix system) scenarios can also be included. In some cases, Distributed MIMO and / or Massive MIMO can also support cell-free or UE-centric network deployment scenarios. It should be understood that the above scenarios also apply to TN and / or NTN. It can be understood that due to the scarcity of spectrum resources, whether it is a base station-centric network deployment scenario or a terminal-centric network deployment scenario, TN and NTN can need to share spectrum.

[0058] 2. Beam direction determination in NR system

[0059] In the NR system, the initial access procedure of the terminal device can be completed by detecting the synchronization signal block (Synchronization Signal / PBCH Block, SSB or SS / PBCH block) on the synchronization raster. The SSB is transmitted through the discovery signal transmission opportunity window (Discovery Burst Transmission Window) or the SSB transmission opportunity window. The discovery signal transmission opportunity window or the SSB transmission opportunity window appears periodically, and the period can be configured by the network device through a higher layer parameter.

[0060] One of the main functions of SSB index is to enable the UE to acquire system timing information. In addition to this, SSB index has another function, which is to indicate the quasi co-location (QCL) relationship between SSBs, or it can also be understood that the SSB index can indicate the beam direction. QCL means that the large-scale parameters experienced by the symbols on one antenna port can be inferred from the symbols on another antenna port. The large-scale parameters can include delay spread, average delay, Doppler spread, Doppler shift, and spatial reception parameters. In the 5G NR system, different beams carrying SSBs form an SSB burst set. Different SSB indexes correspond to the time domain position information of different SSBs in the burst set, and also correspond to the specific SSB transmission beam information. SSBs with the same SSB index are considered to have a QCL relationship; or in other words, SSBs with the same SSB index experience the same or similar large-scale parameters of the channel. The UE can assume that the network device uses the same beam to transmit these SSBs; SSBs corresponding to different SSB indexes are not considered to have a QCL relationship because they can come from different transmission beams of the network device and experience different channel transmission characteristics.

[0061] When the terminal device accesses the cell, if there is a service transmission demand, it needs to access the network through the random access process. The resource configuration in the random access process includes PRACH (Physical Random Access Channel, physical random access channel) resource configuration, also known as PRACH transmission opportunity (PRACH Occasion, RO). RO is the time-frequency resource carrying the random access preamble sequence (Preamble). If two-step RACH (Random Access Channel, Random Access Channel) transmission is supported, the resource configuration in the random access process also includes PUSCH (PUSCH, Physical Uplink Shared Channel) resource configuration, also known as PUSCH transmission opportunity (PUSCH Occasion, PO). Among them, the message A (MsgA) in the two-step RACH includes MsgA Preamble and MsgA PUSCH, RO is the time-frequency resource used to carry MsgA Preamble, and PO is the time-frequency resource used to carry MsgA PUSCH.

[0062] The NR system is characterized by supporting downlink multi-beam. Before the network device communicates with the terminal device, the network device needs to know the beam where the terminal device is located and then set the appropriate beam direction in the subsequent data transmission process. Since there is a mapping relationship between the SSB and the RO, the terminal device can select the RO associated with the downlink receiving beam according to the downlink receiving beam to send the PRACH or Msg A in the random access process, and the network device can determine the appropriate downlink receiving beam direction after detecting the PRACH or Msg A.

[0063] It can be understood that in the future 6G communication system, a similar method can also be used to realize beam direction determination.

[0064] 3. Network scenario of sharing spectrum resources

[0065] For example, FIG. 4 is a schematic diagram of TN and NTN sharing spectrum resources according to an embodiment of the present application. Please refer to FIG. 4, the first network device 401 (such as a ground base station) located on the ground in the TN network can perform wireless communication with the terminal device 402 in the communication coverage area provided by the first network device 401, and the second network device 403 (such as a satellite base station) located on the satellite in the NTN network can perform wireless communication with the terminal device 404 in the communication coverage area provided by the second network device 403. The communication coverage area provided by the first network device 401 and the communication coverage area provided by the second network device 403 partially or entirely overlap. If the frequency band used for communication between the first network device 401 and the terminal device 402 and the frequency band used for communication between the second network device 403 and the terminal device 404 partially or entirely overlap, it is necessary to consider how to share spectrum resources to avoid mutual interference between TN and NTN communication transmission and affect the reliability of communication. It should be noted that in the NTN network of this example, the reference point (such as the uplink time synchronization reference point) used to determine how to compensate for the propagation delay in the NTN network is on the second network device 403.

[0066] Exemplarily, FIG. 5 is a schematic diagram of TN and NTN sharing frequency spectrum resources according to another embodiment of the present application. Referring to FIG. 5, a first network device 501 located on the ground in the TN network can perform wireless communication with a terminal device 502 located in the communication coverage area provided by the first network device 501, and a second network device 503 located on the ground in the NTN network can perform wireless communication with a terminal device 505 located in the communication coverage area provided by the second network device 503 through a satellite 504. The communication coverage area provided by the first network device 501 and the communication coverage area provided by the second network device 503 partially or entirely overlap, and / or the first network device 501 and the second network device 503 have a certain association relationship, for example, the first network device 501 and the second network device 503 are located at the same position or the distance between the first network device 501 and the second network device 503 is less than or equal to a threshold value. If the frequency band used for communication between the first network device 501 and the terminal device 502 and the frequency band used for communication between the satellite and the terminal device 505 partially or entirely overlap, and / or if the frequency band used for communication between the first network device 501 and the terminal device 502 and the frequency band used for communication between the satellite and the second network device 503 partially or entirely overlap, it is necessary to consider how to share the frequency spectrum resources to avoid mutual interference between the TN and the NTN in the communication transmission and affect the reliability of the communication. It should be noted that in the NTN network of this example, the reference point is on the communication link between the second network device 503 and the satellite 504, or on the second network device 503, or on the satellite 504.

[0067] In the case of partially or entirely overlapping frequency bands used for communication, in order to avoid transmission interference, the frequency resources used by the two networks for communication can be made orthogonal. For example, at least one of the following modes can be considered: spatial division multiplexing, time division multiplexing, frequency division multiplexing. Which multiplexing mode is used and how to multiplex after the multiplexing mode is determined need to be determined by the network devices of the two networks through coordination. The present application mainly considers the frequency resource multiplexing mode based on time division.

[0068] 4. Discontinuous communication transmission scenario

[0069] In the NTN system, the satellite provides services to the ground, and the area covered by the communication service is large. Considering that the total transmit power of the satellite is limited, in order to enable the terminal device on the ground to normally access the satellite network, the SNR (Signal Noise Ratio) required by different downlink channels needs to be met. Exemplarily, assuming that the system bandwidth is 30 MHz, the total transmit power of the satellite is 18.8 dBW, and the SNR required by different downlink channels is met, the satellite can have at most 24 groups of activated satellite antenna beams at each moment, wherein each group of satellite antenna beams corresponds to a coverage range with a diameter of 50 km. That is, in order to use 24 groups of activated satellite antenna beams to realize the coverage range of a satellite, an analog beamforming technology can be used, that is, by using a phase shifter to change the phase on the channel corresponding to each antenna, a group of antennas can form beams in different directions, so as to realize the coverage of the satellite by beam sweeping, that is, using beams corresponding to different directions at different moments to cover different areas in the coverage range of the satellite. Based on the above assumption, Table 1 gives the coverage information of the satellite under different minimum UE elevation angles.

[0070] Table 1

[0071] The above-mentioned way of realizing the coverage of the satellite by beam sweeping can also be called discontinuous communication transmission. FIG. 6 gives a schematic diagram of this discontinuous communication transmission scenario. As shown in FIG. 6, different areas in the coverage range of the satellite are associated with different cells, or different areas in the coverage range of the satellite are associated with different cell groups. The satellite can have at most M groups of activated satellite antenna beams at each moment, wherein each group of satellite antenna beams corresponds to the coverage range of a cell, and the satellite corresponds to the coverage range of a cell group at each moment, and each cell group includes M cells. At t0 moment, the M groups of satellite antenna beams serve the first cell group (cell-i, cell-j, …, cell-m); at t1 moment, the M groups of satellite antenna beams switch to serve the second cell group (cell-i+1, cell-j+1, …, cell-m+1); …, and so on, until the coverage of the satellite is realized. Wherein, the service time of each cell is the time length between adjacent two moments. For example, the service time of the cell in the first cell group is the time length between T0 moment and T1 moment.

[0072] That is, in the non-continuous communication transmission scenario of the NTN network, the second network device implements cell coverage through beam scanning. For each cell, the service time is discontinuous. Assuming that the satellite corresponding to the second network device can have at most M groups of activated satellite antenna beams at each moment, each group of satellite antenna beams corresponds to the coverage range of a cell, that is, the satellite corresponds to the coverage range of a cell group at each moment, and each cell group includes M cells. In order to realize the coverage of the satellite, the number of moments of satellite antenna beam scanning is N, that is, the satellite needs to serve N cell groups through beam scanning. The coverage range of the satellite includes M*N cells in total. The service time of each cell is the time length between adjacent two moments. For example, the service time of the cell in the nth cell group is the time length between Tn moment and Tn+1 moment, n=0, 1, …, N-1.

[0073] In some embodiments, since the second network device provides non-continuous communication transmission through satellite antenna beam scanning, for each cell, the serviceable time can be planned in advance. When the coverage range of the ground cell of the first network device partially or entirely overlaps with the coverage range of the satellite cell of the second network device (usually the coverage range of the satellite cell is much larger than that of the ground cell), if the first network device can obtain the service time information of the satellite cell overlapping with the coverage range of the ground cell, the first network device can stop serving in the time period in which the satellite cell is served, and provide service for the ground cell in the time period in which the satellite cell is not served, thereby achieving the effect of sharing the frequency spectrum of NTN and TN in time division.

[0074] Please refer to FIG. 7, which shows the flowchart of the wireless communication method provided by an embodiment of the present application. The method is executed by the first network device, which is the network device of the first cell. The method includes at least one of steps 710-720.

For example, the first spectrum resource is for both downlink communication of the first network device and the second network device and uplink communication of the first network device and the second network device.

[0092] In some embodiments, the first network device and the second network device use the first spectrum resource in the same direction.

[0100] In some embodiments, all of the time domain resources in the first time domain resources are time domain resources in which the first network device serves the first cell in the first period. That is, the first time domain resources are equivalent to time domain resources in which the first network device serves the first cell in the first period.

[0101] In some embodiments, all of the time domain resources in the second time domain resources are time domain resources in which the second network device serves the second cell in the first period.

[0121] In some embodiments, the first time-domain resource is determined based on a timing reference (TR) of the second cell.

[0122] In some embodiments, the second time-domain resource is determined based on a timing reference of the second cell.

[0123] The timing reference of the second cell is used to reflect a timing at which the network device (the second network device) serves the second cell.

[0124] In some embodiments, the time-domain resource allocation pattern comprises the first time information and / or the second time information. In some embodiments, the time-domain resource allocation pattern is used to determine the first time information and / or the second time information.

[0125] The first time information comprises at least one of: time information at which the second device does not serve the second cell, time information at which the second device does not serve the second cell in downlink, and time information at which the second device does not serve the second cell in uplink. The second time information comprises at least one of: time information at which the second device serves the second cell, time information at which the second device serves the second cell in downlink, and time information at which the second device serves the second cell in downlink.

[0126] In some embodiments, the first time-domain resource and / or the second time-domain resource is determined according to the first time information and / or the second time information. For example, based on the first time information, part or all of the time-domain resources in the first period during which the second device does not serve the second cell are determined as the first time-domain resource. For example, based on the second time information, the second time-domain resource is determined (e.g., directly determining the time-domain resources in the first period during which the second device serves the second cell as the second time-domain resource).

[0135] Step 720, the first network device provides service for the first cell according to the first time domain resource and / or the second time domain resource.

[0136] The implementation of this step is explained in the following three cases:

[0137] Case 1, the first network device determines the time domain resource of the first network device providing service for the first cell and / or the time domain resource of the first network device not providing service for the first cell in the first period according to the first time domain resource.

[0138] In some embodiments, the first network device determines all time domain resources within the first time domain resource as the time domain resources in which the first network device serves the first cell in the first period.

[0139] In some embodiments, the first network device determines part of the time domain resources within the first time domain resource as the time domain resources in which the first network device serves the first cell in the first period.

[0140] In some embodiments, there is a first interval duration between a start position of the time domain resources in which the first network device serves the first cell in the first period and a start position of the first time domain resource.

[0141] In some embodiments, there is a first interval duration between an end position of the time domain resources in which the first network device serves the first cell in the first period and an end position of the first time domain resource.

[0142] In some embodiments, the first network device determines the remaining time domain resources in the first period except the first time domain resource as the time domain resources in which the first network device does not serve the first cell.

[0143] In some embodiments, the first network device determines the remaining time domain resources in the first period except the time domain resources in which the first cell is served as the time domain resources in which the first network device does not serve the first cell.

[0144] Case 2, the first network device determines the time domain resources in which the first network device serves the first cell and / or does not serve the first cell in the first period according to the second time domain resource.

[0145] In some embodiments, the first network device determines all time domain resources within the second time domain resource as the time domain resources in which the first network device does not serve the first cell in the first period.

[0146] In some embodiments, the first network device determines the remaining time domain resources in the first period except the second time domain resource as the time domain resources in which the first network device serves the first cell.

[0147] In some embodiments, there is a first interval duration between an end position of the time domain resources in which the first network device serves the first cell in the first period and a start position of the second time domain resource.

[0148] In some embodiments, there is a first interval duration between a start position of the time domain resources in which the first network device serves the first cell in the first period and an end position of the first time domain resource.

[0149] In case 3, the first network device determines, according to the first time domain resource and the second time domain resource, time domain resources in which the first network device serves the first cell and / or time domain resources in which the first network device does not serve the first cell.

[0150] In some embodiments, the first network device determines, as time domain resources in which the first network device serves the first cell in the first period, all time domain resources in the first time domain resource, and determines, as time domain resources in which the first network device does not serve the first cell in the first period, all time domain resources in the second time domain resource.

[0151] In some embodiments, the first network device determines, as time domain resources in which the first network device serves the first cell in the first period, part of the time domain resources in the first time domain resource, and determines, as time domain resources in which the first network device does not serve the first cell in the first period, all time domain resources in the second time domain resource and the remaining time domain resources in the first time domain resource.

[0152] In some embodiments, the wireless communication method further includes step 730 (not shown in FIG. 7).

[0153] In step 730, the first network device sends the second indication information.

[0154] In some embodiments, the first network device sends the second indication information to the terminal device.

[0155] The second indication information is used to determine at least one of the following: the first time domain resource, the second time domain resource, time domain resources in which the first network device serves the first cell in the first period, and time domain resources in which the first network device does not serve the first cell in the first period. In some embodiments, the second indication information directly indicates the above at least one, thereby directly informing the terminal device of the service mode determined by the first network device for the first cell.

[0156] In the technical scheme provided in the embodiments of the present application, the second network device serves the first cell based on the first time domain resource and / or the second time domain resource in the first period determined by the time domain resource allocation pattern. Since the first time domain resource is used to determine time domain resources in which the first network device serves the first cell in the first period, and the second time domain resource is used to determine time domain resources in which the second network device serves the second cell in the first period, the first network device can serve the first cell in a more reasonable time domain resource, thereby avoiding the time domain resources in which the first network device serves the first cell in the first period from overlapping with the time domain resources in which other network devices (such as the second network device) serve other cells (such as the second cell) in the first period, and further avoiding mutual interference between the first cell and the other cell in the case of sharing spectrum resources between the first cell and the other cell, which helps to improve the reliability of communication.

[0157] Referring to FIG. 8, a flowchart of a wireless communication method according to another embodiment of the present application is shown. The method is performed by a first network device, which is a network device of a first cell. The method includes at least one of steps 810-830.

[0158] At step 810, the first network device receives first indication information, which is used to determine a time-domain resource allocation pattern.

[0159] In some embodiments, the first network device receives the first indication information sent by a second network device. The second network device is a network device of a second cell.

[0160] In some embodiments, the first indication information is used to indicate the time-domain resource allocation pattern.

[0161] It should be noted that, since the second cell mentioned in the present application can be one or multiple, and multiple second cells can correspond to different second network devices respectively, the first network device can receive multiple different first indication information, and correspondingly, the time-domain resource allocation pattern can also be multiple.

[0162] In some embodiments, the first network device determines the time-domain resource allocation pattern according to the first indication information.

[0163] In some embodiments, the first indication information is carried in at least one of the following signaling: DCI (Downlink Control Information), RRC (Radio Resource Control) signaling, MAC CE (MAC Control Element), system message, and paging message.

[0164] In some embodiments, the first indication information is carried in at least one of the following channels: PDCCH (Physical Downlink Control Channel) scheduling a system message, PDCCH scheduling a paging message, PDCCH carrying PEI (Paging Early Indication), PDCCH activating or deactivating cell discontinuous transmission and / or discontinuous reception, PDSCH (Physical Downlink Shared Channel) carrying a system message, and PDSCH carrying a paging message.

[0165] In some embodiments, the first indication information is used to determine at least one of the following information: a starting position of the first period, a length of the first period, a length of the first time domain resource, a starting position of the first time domain resource, an ending position of the first time domain resource, a length of the second time domain resource, a starting position of the second time domain resource, an ending position of the second time domain resource. In some embodiments, the time domain resource allocation pattern comprises at least one of the above information. In some embodiments, the first indication information is used to indicate at least one of the above information.

[0166] In some embodiments, the first indication information is used to determine the first period and the first time domain resource, and the second time domain resource is a part of the time domain resource corresponding to the first period and not belonging to the first time domain resource. In some embodiments, the time domain resource allocation pattern comprises the first period and the second time domain resource. In some embodiments, the first indication information is used to indicate the first period and the second time domain resource.

[0167] For example, if the length of the first period is 50 ms (including 5 radio frames of 10 ms), the first time domain resource is the first radio frame, the 5th-9th ms of the second radio frame, the third radio frame, the fourth radio frame and the fifth radio frame, and the second time domain resource is the 0th-4th ms of the second radio frame in the first period.

[0168] In some embodiments, the first indication information is used to determine the first period and the second time domain resource, and the first time domain resource is a part of the time domain resource corresponding to the first period and not belonging to the second time domain resource. In some embodiments, the time domain resource allocation pattern comprises the first period and the second time domain resource. In some embodiments, the first indication information is used to indicate the first period and the second time domain resource.

[0169] For example, if the length of the first period is 50 ms (including 5 radio frames of 10 ms), the second time domain resource is the 0th-4th ms of the second radio frame in the first period, and the first time domain resource is the first radio frame, the 5th-9th ms of the second radio frame, the third radio frame, the fourth radio frame and the fifth radio frame in the first period.

[0170] In some embodiments, the first indication information is used to determine an association relationship between at least one cell and a time domain resource corresponding to the at least one cell in the first period, and the at least one cell comprises the second cell. In some embodiments, the time domain resource allocation pattern comprises the association relationship between the at least one cell and the time domain resource corresponding to the at least one cell in the first period. In some embodiments, the first indication information is used to indicate the association relationship between the at least one cell and the time domain resource corresponding to the at least one cell in the first period.

[0171] In some embodiments, the at least one cell comprises respective cells served by the second network device. The time domain resource corresponding to the cell refers to a time domain resource served by the second network device for the cell.

[0172] Exemplarily, if the second network device serves 20 cells, the first indication information is used to determine the association relationship between the 20 cells and the corresponding time domain resources.

[0173] In some embodiments, the first indication information is used to determine at least one of the following information: a number of cell groups (a cell group comprises a plurality of cells) served by the second network device, a time length of each cell group served by the second network device, a period (a first period) in which each cell group is served by the second network device, and a starting position of the serving time of each cell group in the first period. In some embodiments, the time domain resource allocation pattern comprises at least one of the above information. In some embodiments, the first indication information is used to indicate at least one of the above information. In some embodiments, the first indication information is further used to determine (indicate) a number of a cell group in which the second cell is located.

[0174] In step 820, the first network device determines the first time domain resource and / or the second time domain resource in the first period according to the time domain resource allocation pattern.

[0175] In some embodiments, the first indication information is used to determine at least one of the following information: a starting position of the first period, a length of the first period, a length of the first time domain resource, a starting position of the first time domain resource, and an ending position of the first time domain resource. The first network device determines the first time domain resource in the first period based on at least one of the above information.

[0176] In some embodiments, the first indication information is used to determine at least one of the following information: a starting position of the first period, a length of the first period, a length of the second time domain resource, a starting position of the second time domain resource, and an ending position of the second time domain resource. The first network device determines the second time domain resource in the first period based on at least one of the above information.

[0177] In some embodiments, the first indication information is used to determine the first period and the first time domain resource. The first network device determines, as the second time domain resource, a part of the time domain resource corresponding to the first period which does not belong to the first time domain resource.

[0178] In some embodiments, the first indication information is used to determine the first period and the second time domain resource. The first network device determines, as the first time domain resource, a part of the time domain resource corresponding to the first period which does not belong to the second time domain resource.

[0179] In some embodiments, the first network device determines the cell identity of the second cell based on the SSB transmitted by the second network device. Then, the first network device determines the first time domain resource and / or the second time domain resource according to the cell identity of the second cell and the first indication information.

[0180] For example, the first indication information is used to determine the association between at least one cell and the time domain resource corresponding to the at least one cell in the first period. The first network device determines the time domain resource corresponding to the second cell according to the cell identity of the second cell and the association. The first network device determines the first time domain resource and / or the second time domain resource according to the time domain resource corresponding to the second cell. For example, the first network device directly determines the time domain resource corresponding to the second cell as the second time domain resource, and determines the part of the time domain resource corresponding to the first period that does not belong to the second time domain resource as the first time domain resource.

[0181] In some embodiments, the first indication information is used to determine at least one of the following information: the number of cell groups served by the second network device (a cell group includes multiple cells), the length of time during which the second network device serves each cell group, the period (the first period) during which the second network device serves each cell group, and the starting position of the service time of each cell group in the first period. The first network device determines the time domain resource corresponding to the cell group in which the second cell is located according to at least one of the above information and the number of the cell group in which the second cell is located. The first network device determines the first time domain resource and / or the second time domain resource according to the time domain resource corresponding to the cell group in which the second cell is located. For example, the first network device directly determines the time domain resource corresponding to the cell group in which the second cell is located as the second time domain resource, and determines the part of the time domain resource corresponding to the first period that does not belong to the second time domain resource as the first time domain resource.

[0182] At step 830, the first network device provides service for the first cell according to the first time domain resource and / or the second time domain resource.

[0183] In the following, the above steps are exemplarily described through specific embodiments.

[0184] In embodiment 1, the first indication information is used to indicate the number N of cell groups served by the second network device and the length S of service time of each cell group, where N=10, S=5 ms, the first period=NS=50 ms, the starting position of the service time of the 0th cell group starts from the radio frame numbered 5*F, F is an integer, the service time of the 0th cell group is from the 0th to 4th millisecond of the radio frame 5*F, the service time of the 1st cell group is from the 5th to 9th millisecond of the radio frame 5*F, the service time of the 2nd cell group is from the 0th to 4th millisecond of the radio frame 5*F+1, and so on, and the service time of the 9th cell group is from the 5th to 9th millisecond of the radio frame 5*F+4.

[0185] As shown in FIG. 9, assuming that the first indication information is also used to determine that the cell group number in which the second cell is located is 2, and since the service time of the second cell group is 0-4 ms of radio frame 5*F+1, the first network device (or the terminal device) can determine 0-4 ms of radio frame 5*F+1 as the second time domain resource, and determine the remaining time domain resources, i.e., 5-9 ms of radio frame 5*F+1, 5*F+2, 5*F+3, 5*F+4, as the first time domain resource.

[0186] As shown in FIG. 10, the second time domain resource (10-14 ms in every 50 ms) is the time domain resource in which the second network device serves the second cell in the first period (also the time domain resource in which the first network device does not serve the first cell in the first period), and the first network device can determine the first time domain resource (0-9 ms and 15-49 ms in every 50 ms) as the time domain resource in which the first network device serves the first cell in the first period (also the time domain resource in which the second network device does not serve the first cell in the first period), and it can be seen that, in the first period, the time domain resource in which the first network device serves the first cell and the time domain resource in which the second network device serves the second cell do not overlap in the time domain, and even if they share the frequency spectrum resource, no interference occurs.

[0187] In embodiment 2, the first indication information is used to indicate the number N of cell groups served by the second network device and the first period T, where N=5 and T=20 ms, and the service time length S of each cell group is T / N=4 ms. Starting from the radio frame with an even number, in every two consecutive radio frames, the terminal device can determine the start position of the service time of each cell group according to n*S, where n is the number of the cell group, n=0, 1, …, N-1. That is, the service time of the cell in the nth cell group is n*S to (n+1)*S-1 ms in every two consecutive radio frames.

[0188] As shown in FIG. 11, assuming that the first indication information is also used to determine that the number of the cell group in which the second cell is located is 2, the first network device (or the terminal device) can determine, according to the above information, that the service time of the second cell group is 8-11 ms in every two consecutive radio frames, and further determine that the second time domain resource is 8-11 ms in every two consecutive radio frames, and determine the remaining time domain resources in every two consecutive radio frames, i.e., 0-7 ms and 12-19 ms in every two consecutive radio frames, as the first time domain resource.

[0189] As shown in FIG. 12, the second time domain resource (8th-11th ms in every 20 ms) is the time domain resource in which the second network device serves the second cell in the first period (also the time domain resource in which the first network device does not serve the first cell in the first period), and the first network device can determine the first time domain resource (0th-7th ms and 12th-19th ms in every 20 ms) as the time domain resource in which the first network device serves the first cell in the first period (also the time domain resource in which the second network device does not serve the first cell in the first period). It can be seen that, in the first period, the time domain resource in which the first network device serves the first cell and the time domain resource in which the second network device serves the second cell do not overlap in the time domain, and even if they share the frequency spectrum resource, no interference occurs.

[0190] In Embodiment 3, the first indication information is used to indicate that the start position of the service time of each cell group served by the second network device is n*S, where n is the number of the cell group, n = 0, 1, …, N-1. The service time of the cell in the nth cell group is the time length between n*S and (n+1)*S-1. Assuming that the service time period length T is 40 ms, starting from the wireless frame numbered 4*F, in every four consecutive wireless frames, the first network device can determine the start position of the service time of each cell group according to n*S, and determine the end position of the service time of each cell group according to (n+1)*S, that is, the service time of the cell in the nth cell group is n*S to (n+1)*S-1 ms in every four consecutive wireless frames.

[0191] As shown in FIG. 13, assuming that the first indication information is also used to determine that the cell group in which the second cell is located is numbered 0 and S = 10 ms, the first network device (or the terminal device) can determine, according to the above information, that the service time of the 2nd cell group is the 1st wireless frame in every four consecutive wireless frames, and further determine that the second time domain resource is the 1st wireless frame in every four consecutive wireless frames, and determine the remaining time domain resources in every four consecutive wireless frames, that is, the 2nd, 3rd and 4th wireless frames in every four consecutive wireless frames, as the first time domain resource.

[0192] As shown in FIG. 14, the second time domain resource (0-9 ms in every 40 ms) is the time domain resource in which the second network device serves the second cell in the first period (also the time domain resource in which the first network device does not serve the first cell in the first period), and the first network device can determine the first time domain resource (10-39 ms in every 40 ms) as the time domain resource in which the first network device serves the first cell in the first period (also the time domain resource in which the second network device does not serve the first cell in the first period). It can be seen that, in the first period, the time domain resource in which the first network device serves the first cell and the time domain resource in which the second network device serves the second cell do not overlap in the time domain, and even if they share the frequency spectrum resource, no interference occurs.

[0193] In the technical scheme provided in the embodiments of the present application, the first network device determines the time domain resource allocation pattern by receiving the first indication information. Since the first indication information is sent by the network device (the second network device) of the other cell (the second cell), when the first network device serves the first cell based on the first time domain resource and / or the second time domain resource in the first period determined according to the time domain resource allocation pattern, interference with the other cell due to sharing of the frequency spectrum can be avoided, and the reliability of communication is improved.

[0194] Please refer to FIG. 15, which shows a flowchart of a wireless communication method provided in another embodiment of the present application. The method is performed by a second network device, which is the network device of a second cell. The method includes the following step 1510.

[0195] In step 1510, the second network device sends first indication information, which is used to determine a time domain resource allocation pattern.

[0196] The time domain resource allocation pattern is used to determine a first time domain resource and / or a second time domain resource in a first period.
