[0110] In this embodiment, the relay device can be a device with wireless transceiver capabilities. The network transmission distance can be extended by re-receiving or forwarding data signals.

[0111] Below, in conjunction with Figure 1 The connection links of the relay equipment are described in detail.

[0112] Figure 1 This is a schematic diagram illustrating the connection links between the relay device, terminal device, and network device provided in this application embodiment. Please refer to... Figure 1 This includes control links, backhaul links, and access links.

[0113] The control link is used to connect network devices and relay devices, carrying control data from the network devices to the relay devices. Control data can be transmitted via the control link to instruct the relay devices on certain behaviors. For example, configuration information can be transmitted via the control link. Uplink signals, such as confirmation messages sent by the relay devices to the network devices, can also be transmitted via the control link.

[0114] The backhaul link is used to connect network devices and relay devices, carrying data between them. When the control link and backhaul link use the same carrier, they can communicate using the same beam.

[0115] Access links are used to connect relay devices and terminal devices, carrying data between them.

[0116] The relay equipment includes a mobile termination (MT) module and a forwarding (Fwd) module. The MT module receives side control information from the network device on the control link and sends uplink signals such as acknowledgments to the network device. The forwarding module forwards signals and / or data from the terminal device and network device through the backhaul link and access link.

[0117] To facilitate understanding, the following will be combined with... Figure 2 The application scenarios of the embodiments of this application will be described.

[0118] Figure 2 This is a schematic diagram illustrating an application scenario provided by an embodiment of this application. Please refer to [link / reference]. Figure 2 This includes network device 201, relay device 202a, relay device 202b, terminal device 203a, and terminal device 203b. Relay device 202a and relay device 202b are located within the coverage area of ​​network device 201, while terminal device 203a and terminal device 203b may be located within or outside the coverage area of ​​network device 201.

[0119] Relay device 202a can receive data and / or signals sent by network device 201 and forward them to terminal device 203a. Relay device 202a can also receive data and / or signals sent by terminal device 203a and forward them to network device 201.

[0120] Relay device 202b can receive data and / or signals sent by network device 201 and forward them to terminal device 203b. Relay device 202b can also receive data and / or signals sent by terminal device 203b and forward them to network device 201.

[0121] As an example, only two relay devices and two terminal devices are shown here, but this application is not limited to this. The number of relay devices located within the coverage of network device 201 can be more, and the number of terminal devices communicating with each relay device can also be more.

[0122] When relay equipment forwards data and / or signals in a directed manner, it may cause interference to other terminal equipment or relay equipment. For example... Figure 2 As shown, when relay device 202b forwards data and / or signals to terminal device 203b, it may interfere with the downlink data forwarding of relay device 202a, and may also interfere with the reception of downlink data by terminal device 203a.

[0123] In view of this, embodiments of this application provide a communication method in which a network device configures different ON-OFF patterns for relay devices participating in interference control. The relay devices participating in interference control determine their own shutdown state according to their respective ON-OFF patterns. Each relay device operates in a different shutdown state, which can reduce the interference from the interference source relay device to the interfered relay device and / or terminal device.

[0124] The technical solutions shown in this application will be described below through specific embodiments. It should be noted that the following embodiments may exist independently or in combination with each other, and the same or similar content will not be described again in different embodiments.

[0125] Figure 3 Flowchart of the communication method provided in the embodiments of this application Figure 1 Please see. Figure 3 The method may include:

[0126] S301. Determine the configuration information of the network device.

[0127] Configuration information can be used to indicate the switching pattern of the first relay device.

[0128] Network devices can determine configuration information based on the number of relay devices involved in interference control.

[0129] The configuration information may include multiple sub-configuration information, each of which can be used to indicate the switching pattern of the relay device. For multiple relay devices participating in interference control, the configuration information received by each relay device can be the same.

[0130] For example, the configuration information includes three sub-configuration information, and the relay device can determine the switching pattern of the relay device based on any one of the three sub-configuration information.

[0131] The configuration information can also include only one sub-configuration information. For multiple relay devices participating in interference control, the configuration information received by each relay device can be different.

[0132] The configuration information for each relay device can be determined based on the number of terminal devices served by the relay device.

[0133] For example, if there are three relay devices involved in interference control, namely relay device 1, relay device 2 and relay device 3, and relay device 1 serves the most terminal devices, then a shorter shutdown duration can be configured for relay device 1.

[0134] S302. The network device sends configuration information to the first relay device.

[0135] The first relay device can be a relay device involved in interference control. Relay devices involved in interference control include the interference source relay device and the interfered relay device. The interfered relay device can be a relay device directly interfered with, or it can be a relay device served by the interfered terminal device.

[0136] Network devices can pre-define configuration information according to protocols, or they can pre-configure relay devices through radio resource control (RRC).

[0137] S303. The relay equipment determines the first interruption pattern based on the configuration information.

[0138] The first interruption pattern can be used to indicate the time period of the first relay device's open state and closed state. The open state can refer to the first relay device forwarding uplink and downlink data, while the closed state can refer to the first relay device stopping uplink and downlink data forwarding or stopping downlink data forwarding.

[0139] The duration of the open state can be the same as the duration of the closed state, or the duration of the open state can be less than the duration of the closed state, or the duration of the open state can be greater than the duration of the closed state.

[0140] Within an open / closed pattern, the open state can be a continuous period, and the closed state can be a continuous period or multiple discontinuous periods. The durations of the multiple discontinuous periods can be the same or different.

[0141] To facilitate understanding, the following will be combined with... Figure 4a, Figure 4b and Figure 4c The fracture diagram is explained in detail.

[0142] Figure 4a This is a schematic diagram of the time-domain structure of an opening pattern provided in an embodiment of this application. Please refer to... Figure 4a The open state is a continuous time period from time t1 to time t2, and the closed state is a continuous time period from time t2 to time t3, where t1 < t2 < t3.

[0143] Figure 4b This is a schematic diagram of the time-domain structure of another break pattern provided in an embodiment of this application. Please refer to... Figure 4b The open state represents a continuous time interval from time t2 to time t3, while the closed state represents two discontinuous time intervals: a continuous time interval from time t1 to time t2, and a continuous time interval from time t3 to time t4. The duration of the interval from time t1 to time t2 is the same as the duration of the interval from time t3 to time t4, where t1 < t2 < t3 < t4.

[0144] Figure 4c This is a schematic diagram of the time-domain structure of another breaking pattern provided in an embodiment of this application. Please refer to... Figure 4c The open state represents a continuous time interval from time t2 to time t3, while the closed state represents two discontinuous time intervals: a continuous time interval from time t1 to time t2, and a continuous time interval from time t3 to time t4. The duration from time t1 to time t2 is longer than the duration from time t3 to time t4, where t1 < t2 < t3 < t4.

[0145] Break patterns can be periodically repeating patterns. Periodic configuration information for break patterns can be obtained from network devices. This information includes the break pattern's period and offset. The period refers to the number of slots in which the break pattern repeats, and the offset refers to the slot in which the break pattern begins within a given period.

[0146] For example, if the periodic configuration information is (slot 4,2), it means that the break pattern is repeated every 4 slots, and the break pattern starts in slot number 2.

[0147] After receiving an instruction, the relay device can begin interference control. During the interference control period, it will periodically repeat the on / off pattern until it receives an instruction to stop interference control.

[0148] exist Figure 3In the illustrated embodiment, the network device determines configuration information and sends the configuration information to the first relay device. The first relay device, based on the configuration information, determines a first on / off pattern. This first on / off pattern indicates the time periods during which the first relay device is in an on state and the time periods during which it is in a off state. Relay devices participating in interference control can determine their own on / off patterns based on the configuration information, and can determine their own off state based on the on / off patterns. Each relay device operates in different off states, which can reduce interference from the source relay device to the affected relay devices and / or terminal devices.

[0149] exist Figure 3 Based on the illustrated embodiment, the above communication method will be described in detail below through several specific methods. Among them, Figure 5 The embodiments shown represent multiple display configuration methods. Figure 8 The embodiment shown is a single display configuration. Figure 9 The example shown is an implicit configuration method.

[0150] Figure 5 Flowchart of the communication method provided in the embodiments of this application Figure 2 Please see. Figure 5 The method may include:

[0151] S501, Network device configuration information is determined.

[0152] Network devices can determine their configuration information in the following ways:

[0153] Based on the locations of multiple relay devices, a first number of relay devices participating in interference control is determined; based on the first number, the configuration information is determined.

[0154] Optionally, the first number of relay devices participating in interference control can be determined based on the frequency resources allocated by the network device to each relay device, or based on the beam direction indicated by the network device to each relay device. This application does not impose specific limitations on this.

[0155] There are two configuration methods for configuration information: uniform configuration and non-uniform configuration. Uniform configuration indicates that the open state occupies the same amount of time for multiple relay devices participating in interference control within the total duration of the opening and closing pattern. Non-uniform configuration indicates that the open state occupies different amounts of time for multiple relay devices participating in interference control within the total duration of the opening and closing pattern.

[0156] In one possible implementation, non-uniform configuration can also indicate that multiple relay devices involved in interference control have the same duration of open state within the total duration of the switching pattern, except that the features included in the configuration information are different from those included in uniform configuration.

[0157] When configured uniformly, the configuration information may include: the identifiers of multiple break patterns, the total duration of the break patterns, and the first number of relay devices participating in interference control.

[0158] Among them, the markings of the fracture pattern can not only indicate different fracture patterns, but also indicate the position of the open state in the fracture pattern.

[0159] The initial number of relay devices involved in interference control can be used to determine the duration of each relay device's open state in the total duration of the interruption pattern.

[0160] When the configuration is non-uniform, the configuration information may include: the identifiers of multiple break patterns, the total duration of the break patterns, and the status information corresponding to the open state in each break pattern. The status information includes the opening time and opening duration of the open state.

[0161] S502, The network device sends configuration information to the first relay device.

[0162] It should be noted that the execution process of S502 can be found in the execution process of S302, and will not be repeated here.

[0163] S503. The network device sends a first instruction message to the first relay device. The first instruction message includes a first disconnection pattern identifier.

[0164] The first instruction information can be either media access control-control element (MAC-CE) signaling or downlink control information (DCI), and this application does not impose any specific restrictions on it.

[0165] The first indication information received by the multiple relay devices involved in interference control is different, and the identification of the switching pattern indicated by each first indication information is different.

[0166] In the first indication information, the bit width N2 occupied by the first interruption pattern identifier is determined based on the first number M of relay devices participating in the interference control, where the first number is an integer greater than or equal to 2.

[0167] In one possible implementation, N² = log₂M bits.

[0168] For example, when there are two relay devices involved in interference control, N2 is 1 bit; the identifiers of the first interrupt patterns of the two relay devices can be 0 or 1 respectively.

[0169] When the configuration information does not include the first quantity, the first indication information also includes the first quantity.

[0170] In the first instruction information, the bit width N1 occupied by the first quantity is based on the preset maximum quantity N. max The predetermined maximum number is the maximum number of relay devices participating in interference control, and the predetermined maximum number is an integer greater than or equal to the first number.

[0171] In one possible implementation, N1 = log2(N max -1) bits.

[0172] For example, when the maximum number of relay devices participating in interference control is 2, this part of the indication can be omitted, that is, 0 bits; when the maximum number of relay devices participating in interference control is 3, the bit width of this part is 1 bit. At this time, the bit value can be used to indicate whether the number of relay devices currently participating in interference control is 2 or 3. When the number of relay devices participating in interference control is 3, the identifiers of the 3 relay devices indicated by the first indication information are 100, 101 and 110 respectively.

[0173] S504. The first relay device can determine the first break pattern based on the identification and configuration information of the first break pattern.

[0174] The start time of each break pattern (the start time of interference control) can be determined based on the semi-static configuration of the relay equipment by the network device. This semi-static configuration can be periodic or semi-persistent. Periodic configuration requires determining the period and offset of each break pattern; for periodic configuration, it repeats cyclically until the channel semi-static configuration is received. Semi-persistent configuration is similar to periodic configuration, but additionally requires activation and deactivation processes at the medium access control (MAC) layer.

[0175] Different configuration information can determine the first break pattern in different ways.

[0176] When the configuration information is uniform, the first relay device can determine the first interruption pattern in the following way:

[0177] Based on the first quantity in the configuration information and the total duration of the interruption pattern, the first duration of the first relay device in the off state is determined; based on the identifier of the first interruption pattern and the first duration, the first moment when the first relay device begins to enter the off state is determined; wherein, the first interruption pattern includes the first moment and the first duration.

[0178] The first break pattern may also include a second moment and a second duration for entering the open state.

[0179] The first duration of being in the closed state can be determined in the following ways: the second duration of being in the open state is determined based on the first quantity in the configuration information and the total duration of the opening and closing pattern; the first duration of being in the closed state is determined based on the second duration and the total duration of the opening and closing pattern.

[0180] For relay devices involved in interference control, each relay device is in the open state for the same duration and in the closed state for the same duration.

[0181] For example, when the first quantity is 3 and the total duration of the open / closed pattern is 6 milliseconds, the second duration of the open state can be determined to be 2 milliseconds, and the first duration of the closed state can be determined to be 4 milliseconds.

[0182] To facilitate understanding, the following will be combined with... Figure 6 The fracture diagram is explained in detail.

Figure 6 The number of relay devices involved in interference control is 3. The on / off patterns of the 3 relay devices configured in the configuration information are identified as A, B and C, respectively. A, B and C also represent the order in which the relay devices enter the open state. The duration of the on / off pattern is 6 milliseconds.

[0184] Based on the first instruction information, it can be determined that the identification of the break diagram of relay device 1 is A, the identification of the break diagram of relay device 2 is B, and the identification of the break diagram of relay device 3 is C.

[0185] Based on the first quantity and the total duration of the interruption pattern, it can be determined that the first duration of each relay device in the open state is 2 milliseconds.

[0186] Based on the identifier of the opening / closing pattern and the first duration, it can be determined that the time when relay device 1 enters the open state is the start time t1 of the opening / closing pattern, and the duration of entering the open state is 2 milliseconds; the time when it enters the closed state is t2(t1+2 milliseconds), and the duration of entering the closed state is 4 milliseconds.

[0187] Based on the markings of the switching pattern and the first duration, it can be determined that the time when relay device 2 enters the first closed state is t1, and the duration of entering the first closed state is 2 milliseconds; the time when it enters the open state is t2(t1+2 milliseconds), and the duration of entering the open state is 2 milliseconds; the time when it enters the second closed state is t3(t2+2 milliseconds), and the duration of entering the second closed state is 2 milliseconds.

[0188] Based on the markings of the switching pattern and the first duration, it can be determined that the time when relay device 2 enters the closed state is t1, and the duration of entering the first closed state is 4 milliseconds; the time when it enters the open state is t3(t1+4 milliseconds), and the duration of entering the open state is 2 milliseconds.

[0189] When the configuration information is non-uniform, the first relay device can determine the first starting pattern in the following way:

[0190] Based on the identifier of the first break pattern, the first state information is determined in the configuration information; based on the total duration of the break pattern and the opening time and opening duration in the first state information, the first moment and first duration for starting to enter the closing state are determined; wherein, the first break pattern includes the first moment and the first duration.

[0191] The opening time can be a relative time between the time of entering the open state and the start time of the open / closed pattern. For example, if the start time of the open / closed pattern is t1, then the opening time of the open state can be a time relative to the interval x milliseconds from t1, that is, the opening time of the open state is (t1+x) milliseconds.

[0192] The first break pattern may also include a second moment and a second duration for entering the open state.

[0193] To facilitate understanding, the following will be combined with... Figure 7 The fracture diagram is explained in detail.

The status information of the 3 relay devices is shown in the table below:

[0195] A t1+5, 1 millisecond B t1+4, 1 millisecond C t1, 4 milliseconds

[0196] Based on the first instruction information, it can be determined that the identification of the break diagram of relay device 1 is A, the identification of the break diagram of relay device 2 is B, and the identification of the break diagram of relay device 3 is C.

[0197] Based on the first indication information, the time T0 at which each relay device begins interference control can be determined. Based on T0 and the periodic configuration information of the switching pattern, the start time t1 of the switching pattern can be determined. Based on the status information corresponding to identifier A and the total duration of the switching pattern, the time when relay device 1 begins to enter the off state is t1, and the duration of entering the off state is 5 milliseconds; the time when it enters the on state is t1+5 milliseconds (t3), and the duration of entering the on state is 1 millisecond. Based on the status information corresponding to identifier B and the total duration of the switching pattern, the time when relay device 2 begins to enter the first off state is t1, and the duration of entering the first off state is 4 milliseconds; the time when it enters the on state is t1+4 milliseconds (t2), and the duration of entering the on state is 1 millisecond; the time when it enters the second off state is t1+5 milliseconds (t3), and the duration of entering the second off state is 1 millisecond. Based on the status information corresponding to identifier C and the total duration of the opening and closing pattern, it can be determined that the time when relay device 3 enters the open state is t1, and the duration of entering the open state is 4 milliseconds; the time when it enters the closed state is t1+4 milliseconds (t2), and the duration of entering the open state is 2 milliseconds.
