Description

[Technical field]

[0001] The present invention relates to the field of communications. [Background technology]

[0002] Compared with traditional 2G (second generation mobile communication technology), 3G (third generation mobile communication technology) and 4G (fourth generation mobile communication technology) systems, 5G (fifth generation mobile communication technology) systems can provide wider bandwidth and higher data rates, and support more types of terminals and diverse industrial services. Therefore, the bandwidth / operating bandwidth supported by the 5G system is much larger than that of the 2G, 3G and 4G systems, and the 5G system supports higher carrier frequencies. For example, the 5G system can be deployed in the millimeter wave band.

[0003] However, the higher the carrier frequency, the greater the signal fading during transmission. Therefore, in the practical deployment of 5G systems, how to better enhance cell coverage, especially in the millimeter wave band, is an urgent problem to be solved.

[0004] The above description of the background art is merely for the purpose of more clearly and completely explaining the configurations of the present invention and for the understanding of those skilled in the art, and should not be construed as meaning that these configurations are well known to those skilled in the art just because they are described in the background art of the present invention. Summary of the Invention [Problem to be solved by the invention]

[0005] In order to better solve the coverage problem in the practical deployment of cellular mobile communication systems, adopting a radio frequency repeater (RF Relay / Repeater) to amplify and forward communication signals between devices is a relatively common deployment method. Radio frequency repeaters are relatively widely applied in the practical deployment of 2G systems, 3G systems and 4G systems, and their advantages are low cost, easy deployment, and no excessive delay increase. Generally, a conventional radio frequency repeater is a device that amplifies and forwards signals between devices in the radio frequency domain. In other words, a conventional radio frequency repeater is a non-regenerative relay node that simply directly amplifies and forwards all received signals.

[0006] In the uplink / downlink time division duplex (UL / DL TDD) configuration of the terminal device of R-17, a flexible region is configured between the downlink region and the uplink region, which allows the terminal device to flexibly use the time domain resources of the region for some sudden transmission, and provides a buffer time after receiving data in the downlink region and before transmitting data in the uplink region, so as to give the terminal device enough time to process the received data and prepare for data transmission.

[0007] In the UL / DL TDD configuration of R-17, the semi-statically configured cell common flexible region may be changed by the dedicated configuration of the terminal device, that is, transmission and reception may be performed in the flexible region according to the dedicated configuration of the terminal device. The dynamic UL / DL TDD configuration of the terminal device can change the semi-statically configured flexible region. If the terminal device does not have a dynamic configuration in the flexible region, the terminal device detects a physical downlink control channel (PDCCH) in the corresponding control resource set (CORESET) according to the search space configuration, and determines the transmission and reception direction in the flexible region according to the instruction of the PDCCH, and the terminal device does not transmit or receive channels and signals in the flexible region until it detects a corresponding scheduling instruction.

[0008] In R-17, in order to improve the coverage of a network device (e.g., a base station), a radio frequency repeater (RF repeater) is proposed to amplify and forward the communication between a terminal device and the network device. The prior art of the forwarding of the radio frequency repeater is solved by the implementation.

[0009] According to the discovery of the inventors of the present invention, the prior art has not proposed an appropriate solution for the TDD configuration for a repeater to perform forwarding, and there is no solution for how a repeater determines forwarding operations and related configuration methods in the flexible area of ​​the TDD configuration for forwarding, so that the repeater cannot flexibly use the flexible area.

[0010] In addition, although it is possible for communication (also referred to as transmission) to occur between a repeater and a network device, the prior art does not take into account the configuration relationship of transmission and forwarding in a flexible area configured by a repeater, and there is no solution for how to determine the transmission and forwarding operations in a flexible area configured by a repeater, so that transmission and forwarding by the repeater may collide within the flexible area.

[0011] In order to solve one or more of the above problems, an embodiment of the present invention provides a repeater configuration method and apparatus. That is, for one or more of the above problems, an embodiment of the present invention provides a corresponding solution. [Means for solving the problem]

[0018] A seventh aspect of an embodiment of the present invention provides a method for configuring a repeater disposed in a network device, the method including a step of the network device transmitting time division duplex (TDD) configuration information to the repeater.

[0019] In an eighth aspect of an embodiment of the present invention, there is provided a computer-readable program which, when executed in a repeater configuration device or a repeater, causes the repeater configuration device or the repeater to execute the repeater configuration method described in the sixth aspect of an embodiment of the present invention.

[0020] In a ninth aspect of an embodiment of the present invention, there is provided a storage medium having a computer-readable program stored thereon, the computer-readable program causing a repeater configuration device or a repeater to execute the repeater configuration method described in the sixth aspect of an embodiment of the present invention.

[0023] One of the advantageous effects of the embodiment of the present invention is as follows.

[0024] By sending TDD configuration information to the repeater, the repeater can determine the configured flexible region, and by the repeater determining the forwarding behavior in the first flexible time unit, the repeater's forwarding can be more flexible to sudden service transmission, and a buffer time between downlink forwarding and uplink forwarding can be provided for the repeater, so that the repeater can have enough time to process the received data and prepare to transmit the service.

[0025] In addition, by taking into consideration the configuration relationship between transmission and forwarding in a flexible area configured by a repeater, it is possible to avoid collisions between transmission and forwarding by the repeater in the flexible area and ensure the reliability of transmission and forwarding by the repeater.

The communication module of the repeater can receive information from the network device via the communication link or the control link. The communication link or the control link may be based on an existing Uu interface. The communication module of the repeater can also apply the information received from the network device to the forwarding module through the internal operation of the repeater.

[0052] The following describes exemplary embodiments of the present invention with reference to scenarios and problems, but the exemplary embodiments of the present invention are not limited thereto.

[0053] 1 is a schematic diagram of an example of a communication method according to an embodiment of the present invention. As shown in FIG. 1, a communication system 100 may include a network device 101, a terminal device 102, and a repeater 103.

[0058] Hereinafter, various aspects of the embodiment of the present invention will be described with reference to the drawings. These aspects are merely illustrative and do not limit the present invention.

[0059] <Example 1> An embodiment of the present invention provides a repeater configuration method, which is applied to a repeater, for example, the repeater 103 in FIG. 1 and FIG. 2. 3 is a schematic diagram of an example of a repeater configuration method according to the first embodiment of the present invention. As shown in FIG. 3, the method includes the following steps:

[0060] Step 301: The repeater receives time division duplex (TDD) configuration information from a network device.

[0061] Step 302: The repeater determines a forwarding behavior in a first flexible time unit.

[0062] Thereby, by sending TDD configuration information to the repeater, the repeater can determine the configured flexible region, and by the repeater determining the forwarding behavior in the first flexible time unit, the forwarding of the repeater can be more flexible to sudden service transmission, and a buffer time between downlink forwarding and uplink forwarding can be provided for the repeater, so that the repeater can have enough time to process the received data and prepare to transmit the service.

[0063] In step 301, the repeater receives time division duplex configuration information from a network device, for example, the repeater receives the time division duplex configuration information via the downlink communication link in FIG. 1 and FIG.

[0064] In some embodiments, the time division duplex configuration may also be referred to as an up / down time division duplex (UL / DL TDD) configuration.

[0065] In some embodiments, the time domain resource configured by the time division duplex configuration information includes at least one time unit of a downlink time unit, a flexible time unit, and an uplink time unit.

[0066] In some embodiments, a downlink time unit may be referred to as a downlink time domain or a downlink domain, an uplink time unit may be referred to as an uplink time domain or an uplink domain, and a flexible time unit may be referred to as a flexible time domain or a flexible domain.

[0067] Fig. 4 is a schematic diagram of an example of a time division duplex configuration according to the first embodiment of the present invention. As shown in Fig. 4, in one time division duplex period, the time domain resource of the time division duplex configuration includes a downlink time unit, a flexible time unit and an uplink time unit.

[0068] In some embodiments, a "time unit," "time domain," or "domain" may be, for example, a period in the time domain, and may include one or more slots and / or one or more symbols, although embodiments of the present invention are not limited in this respect.

[0069] In some embodiments, for a time division duplex configuration for transmission, the repeater performs downlink transmission in downlink time units and uplink transmission in uplink time units.

[0070] In some embodiments, uplink forwarding includes forwarding channels and / or signals transmitted by a terminal device to a network device, and downlink forwarding includes forwarding channels and / or signals transmitted by a network device to a terminal device.

[0071] Also, how the repeater determines the forwarding operation in flexible time units will be specifically described below.

[0072] In some embodiments, the time division duplex configuration includes a semi-static time division duplex configuration and / or a dynamic time division duplex configuration.

[0073] In some embodiments, the semi-static time division duplex configuration is indicated by at least one of RRC signaling, MAC layer signaling, and physical layer signaling, i.e., the semi-static time division duplex configuration is indicated by semi-static signaling.

[0074] For example, a semi-static time division duplex configuration may be indicated by higher layer signaling, for example RRC signaling.

[0075] In some embodiments, the semi-static time division duplex configuration includes a cell-common time division duplex configuration and / or a repeater-dedicated time division duplex configuration.

[0076] In other words, the semi-static time division duplex configuration may include a cell-wide time division duplex configuration, or may include a repeater-only time division duplex configuration, or may include a cell-wide time division duplex configuration and a repeater-only time division duplex configuration.

[0077] In some embodiments, the cell-wide time division duplex configuration is indicated, for example, by semi-static cell-wide signaling, and the repeater-only time division duplex configuration is indicated, for example, by semi-static repeater-only signaling.

[0078] In some embodiments, the cross-cell time division duplex configuration includes configuring one or two patterns.

[0079] For example, the cell-wide time division duplex configuration includes configuring a first pattern (pattern 1), or the cell-wide time division duplex configuration includes configuring a first pattern (pattern 1) and a second pattern (pattern 2).

[0080] For example, a cell-wide time division duplex configuration includes a common configuration parameter, a first pattern (pattern 1) and a second pattern (pattern 2), where the second pattern (pattern 2) is optional, i.e., the second pattern (pattern 2) may or may not be included.

[0081] In some embodiments, when the cell-wide time division duplex configuration includes a configuration of a first pattern (pattern 1), the first pattern (pattern 1) is indicated by at least one of RRC signaling, MAC layer signaling, and physical layer signaling.

[0082] For example, in a first pattern (pattern 1), the associated configuration is indicated by higher layer signaling, for example, the associated configuration is indicated by RRC signaling.

[0083] In some embodiments, the signaling (e.g., RRC signaling) indicating the first pattern (pattern 1) may include a first transmission periodicity value P, a first number of downlink slots d slots , the first downlink symbol number d sym , the first uplink slot number u slots , the first uplink symbol number u sym , and the first flexible symbol number, where these parameters are integers equal to or greater than zero.

[0084] In some embodiments, the first transmission period value is in milliseconds, and the first downlink slot number is the first d slots indicates that this slot is a downlink slot, and the first downlink symbol number is d slots d after slots sym indicates that these symbols are downlink symbols, and the first uplink slot number is the last u slots indicates that this slot is an uplink slot, and the first uplink symbol number is u slots u before slots sym Indicates that this symbol is an uplink symbol.

[0085] For example, for the first pattern (pattern 1) of a cycle, from the first to the last, slots downlink slots, d sym downlink symbols, 0 or more flexible slots or symbols, u sym uplink symbols, u slots sequentially, where d slots , d sym , u sym , and u slotsare all integers greater than or equal to zero.

[0086] In some embodiments, the number of flexible slots and / or symbols may or may not be indicated in the above signaling. If the number of flexible slots and / or symbols is not indicated, other time units than the uplink time units and the downlink time units within the above period may be considered to be flexible slots and / or symbols, where flexible slots and / or symbols are slots and / or symbols of a flexible time unit.

[0087] In some embodiments, when the first pattern is configured, the first symbol of every 20 ms / P period is aligned to or is the first symbol of an even frame, where P is divisible by 20 and 20 ms represents two frame lengths, i.e., each frame length is 10 ms.

[0088] In some embodiments, when the cell common time division duplex configuration includes a first pattern (pattern 1) and a second pattern (pattern 2), the content of the first pattern (pattern 1) is as described above, and the duplicated description is omitted here. The content of the second pattern (pattern 2) is described below.

[0089] In some embodiments, the configuration of the second pattern (pattern 2) is indicated by at least one of RRC signaling, MAC layer signaling, and physical layer signaling.

[0090] For example, in the second pattern (pattern 2), the related configuration is indicated by higher layer signaling, for example, the related configuration is indicated by RRC signaling.

[0091] In some embodiments, the signaling (e.g., RRC signaling) indicating the second pattern (pattern 2) may include a second transmission periodicity value P2, a second downlink slot d slots,2 , the second number of downlink symbols d sym,2 , the second uplink slot u slots,2 , the second number of uplink symbols u sym,2 , and a second flexible symbol number, where these parameters are integers equal to or greater than zero.

[0092] In some embodiments, the second transmission period value is in milliseconds and the second downlink slot number is the first d slots,2 This slot is a downlink slot, and the second downlink symbol number is d slots,2 d after slots sym,2 This indicates that these symbols are downlink symbols, and the second uplink slot number is the last u slots,2 This indicates that this slot is an uplink slot, and the second uplink symbol number is u slots,2 u before slots sym,2 Indicates that this symbol is an uplink symbol.

[0093] For example, for the second pattern (pattern 2) of a cycle, from the first to the last, slots,2 downlink slots, d sym,2 downlink symbols, 0 or more flexible slots or symbols, u sym,2 uplink symbols, u slots,2 sequentially, where d slots,2 , d sym,2 , u sym,2 , and u slots,2 are all integers greater than or equal to zero.

[0094] In some embodiments, the number of flexible slots and / or symbols may or may not be indicated in the above signaling. If the number of flexible slots and / or symbols is not indicated, other time units than the uplink time units and the downlink time units within the above period may be considered to be flexible slots and / or symbols, where the flexible slots and / or symbols are slots and / or symbols of the flexible time units.

[0095] In some embodiments, when the first pattern (pattern 1) and the second pattern (pattern 2) are configured, the first symbol of every 20 ms / (P+P2) periods is aligned to the first symbol of an even frame, or the first symbol of every 20 ms / (P+P2) periods is the first symbol of an even frame, where P+P2 is divisible by 20 and 20 ms represents two frame lengths, i.e., each frame length is 10 ms.

[0096] In some embodiments, the repeater-only time division duplex configuration is configured only in the flexible area unit of the cell-common time division duplex configuration. For example, the repeater-only time division duplex configuration is configured only in the flexible area of ​​the cell-common uplink-downlink TDD configuration. That is, only the flexible area of ​​the cell-common uplink-downlink TDD configuration can be changed, and the uplink area and the downlink area of ​​the cell-common uplink-downlink TDD configuration cannot be changed.

[0097] In some embodiments, the repeater-only time division duplex configuration is indicated by at least one of RRC signaling, MAC layer signaling, and physical layer signaling.

[0098] For example, the repeater-only time division duplex configuration is indicated by higher layer signaling, for example RRC signaling.

[0099] In some embodiments, the signaling indicates the slot position within the period and / or the symbol configuration within the slot.

[0100] For example, the signaling may configure all symbols in a slot to be downlink symbols, or configure all symbols in a slot to be uplink symbols, or configure a number a of downlink symbols and / or a number b of uplink symbols in a slot, where the number of downlink symbols indicates that the first a symbols in the slot are downlink symbols, and the number of uplink symbols indicates that the last b symbols in the slot are uplink symbols, where a and b are both integers equal to or greater than zero.

[0101] As another example, if the number of downlink symbols is not configured, then there are no downlink symbols in the slot. If the number of uplink symbols is not configured, then there are no uplink symbols in the slot. When the number of uplink and / or downlink symbols is configured, the remaining symbols in the slot are flexible symbols.

[0102] Here, the slot is the slot whose position in the period is indicated by the signaling mentioned above.

[0103] The above describes a semi-static time division duplex configuration, and the following describes a dynamic time division duplex configuration.

[0104] In some embodiments, the dynamic time division duplex configuration is indicated by at least one of RRC signaling, MAC layer signaling, and physical layer signaling.

[0105] For example, the dynamic time division duplex configuration is indicated by physical layer signaling. For example, the slot format configuration is dynamically indicated using DCI format 2_0.

[0106] In some embodiments, a dynamic time division duplex configuration may configure a flexible time unit in a semi-static time division duplex configuration, for example, a corresponding slot format may be indicated for the flexible time unit in the semi-static time division duplex configuration so that the dynamic configuration is performed, but the uplink time unit and the downlink time unit in the semi-static time division duplex configuration are not changed.

[0107] In some embodiments, at least one of RRC signaling, MAC signaling, and physical layer signaling may indicate a cell identifier to be applied by the dynamic time division duplex configuration, and / or a slot format indicator (SFI) corresponding to the dynamic time division duplex configuration, and / or a slot format to be applied by the dynamic configuration.

[0108] In some embodiments, the slot format applied by the dynamic configuration described above includes a single structure format, a format having one flexible time unit within a slot, a format having two flexible time units within a slot, or a format indicating that the configuration of the SFI does not affect semi-statically configured signal and / or channel transmissions.

[0109] For example, in a single structure format, all symbols in a slot are uplink symbols, or all symbols in a slot are downlink symbols, or all symbols in a slot are flexible symbols.

[0110] For example, in a format with one flexible time unit in a slot, the slot may include, from first to last, zero or more downlink symbols, one or more flexible symbols, and zero or more uplink symbols.

[0111] For example, in a format with two flexible time units in a slot, the slot may include, from first to last, zero or more downlink symbols, one or more flexible symbols, zero or more uplink symbols, zero or more downlink symbols, one or more flexible symbols, and zero or more uplink symbols, for example, the two flexible regions are located at the first 7 symbols and the last 7 symbols in the slot, respectively.

[0112] In some embodiments, a format indicating that the configuration of the SFI does not affect semi-statically configured signal and / or channel transmission may be referred to as a 255 format, in which the flexible region cannot be changed.

[0113] In some embodiments, if one of the overlapping normal cyclic prefix (normal CP) symbols is flexible, the repeater determines an extended cyclic prefix (extended CP) symbol as the flexible symbol in the flexible time unit, and / or if a pair of overlapping normal cyclic prefix symbols includes a downlink symbol and an uplink symbol, the repeater determines an extended cyclic prefix symbol as the flexible symbol in the flexible time unit.

[0114] In some embodiments, an "overlapping normal cyclic prefix" refers to a normal cyclic prefix that overlaps with an extended cyclic prefix.

[0115] In step 301, the repeater receives time division duplex (TDD) configuration information from a network device, so that the repeater can determine a flexible time unit in the time division duplex configuration, and in step 302, the repeater determines a forwarding operation on a first flexible time unit.

[0116] In some embodiments, the first flexible time unit comprises at least a portion of a flexible time unit in a time division duplex configuration.

[0117] For example, the first flexible time unit is determined based on the flexible time unit in a time division duplex configuration, although the embodiment of the present invention is not limited thereto.

[0118] For example, the first flexible time unit includes a portion of a flexible time unit in a time division duplex configuration, or the first flexible time unit includes an entire flexible time unit, or the first flexible time unit includes a portion of a flexible time unit and other time domain resources, or the first flexible time unit includes an entire flexible time unit and other time domain resources.

[0119] In some embodiments, the forwarding operation includes at least one of an uplink forwarding, a downlink forwarding, and no forwarding.

[0120] In some embodiments, uplink forwarding includes forwarding channels and / or signals transmitted by a terminal device to a network device, and downlink forwarding includes forwarding channels and / or signals transmitted by a network device to a terminal device.

[0121] In some embodiments, the repeater determining a forwarding behavior in the first flexible time unit may be the repeater determining a forwarding behavior in the first flexible time unit according to a first instruction, or may be the repeater determining a forwarding behavior in the first flexible time unit according to a default first rule.

[0122] That is, the repeater may determine, by instruction or by default, a forwarding behavior in the first flexible time unit.

[0123] 5 is a schematic diagram of an example of a method for a repeater according to the first embodiment of the present invention to determine a forwarding operation in a first flexible time unit. As shown in FIG. 5, the method includes step 501 or step 502.

[0124] Step 501: The repeater determines a forwarding behavior in a first flexible time unit according to a first instruction.

[0125] Step 502: The repeater determines a forwarding behavior in a first flexible time unit according to a default first rule.

[0126] In some embodiments, a "default rule" may refer to a predefined rule or convention, such as a convention in a protocol.

[0127] In some embodiments, a directive approach is described.

[0128] In some embodiments, the first indication comprises at least one of physical layer signaling, MAC layer signaling, and RRC signaling. For example, the first indication comprises physical layer signaling, such as a DCI format.

[0129] In some embodiments, when the repeater receives the first indication, the repeater determines uplink forwarding and / or downlink forwarding in the first flexible time unit.

[0130] For example, when the repeater receives the first instruction, the repeater determines a forwarding behavior in the first flexible time unit according to any of the following manners:

[0131] When the repeater receives a first instruction instructing uplink forwarding, the repeater decides to forward the channel and / or signal transmitted by the terminal device to the network device in a first flexible time unit.

[0132] When the repeater receives a first instruction instructing downlink forwarding, the repeater decides to forward the channel and / or signal transmitted by the network device to the terminal device in a first flexible time unit.

[0133] Also, for example, if the repeater does not receive the first instruction, the repeater determines the forwarding behavior in the first flexible time unit according to a default second rule, which includes one of the following rules:

[0134] The repeater performs only downlink transmissions in some or all of the symbols of the first flexible time unit.

[0135] The repeater performs only uplink transmissions in some or all of the symbols of the first flexible time unit.

[0136] The repeater performs downlink transmission in the first n1 symbols of the first flexible time unit and uplink transmission in the second n2 symbols, where n1+n2 is less than or equal to the total number of symbols in the first flexible time unit.

[0137] The repeater does not perform any transmission in the first flexible time unit.

[0138] In some embodiments, the default first rule and second rule may be the same.

[0139] For example, the first rule includes one of the following rules:

[0140] The repeater performs only downlink transmissions in some or all of the symbols of the first flexible time unit.

[0141] The repeater performs only uplink transmissions in some or all of the symbols of the first flexible time unit.

[0142] The repeater performs downlink transmission in the first n1 symbols of the first flexible time unit and uplink transmission in the second n2 symbols, where n1+n2 is less than or equal to the total number of symbols in the first flexible time unit.

[0143] The repeater does not perform any transmission in the first flexible time unit.

[0144] In some embodiments, the default first and second rules may be different.

[0145] In some embodiments, if the repeater determines to perform uplink forwarding and / or downlink forwarding in the first flexible time unit, as shown in FIG. 3, the method further includes the following steps.

[0146] Step 303: The repeater performs uplink transmission and / or downlink transmission in a first flexible time unit.

[0147] In some embodiments, when the repeater determines a forwarding operation in the first flexible time unit, it may further take into account the consistency between the direction of transmission indicated by the first instruction received by the repeater and the direction of transmission indicated by the second instruction received by the terminal device served by the repeater.

[0148] In some embodiments, the repeater determines the repeater's forwarding operation in the first flexible time unit based on whether the direction of forwarding in the first flexible time unit indicated by the received first instruction coincides with the direction of forwarding in the second flexible time unit indicated by the second instruction received by the terminal device served by the repeater.

[0149] For example, if the direction of transmission by the repeater in a first flexible time unit instructed by a received first instruction coincides with the direction of transmission by the repeater in a second flexible time unit instructed by a second instruction received by a terminal device served by the repeater, the repeater performs uplink transmission or downlink transmission in the first flexible time unit.

[0150] If the direction of forwarding by the repeater in the first flexible time unit instructed by the received first instruction does not match the direction of forwarding by the repeater in the second flexible time unit instructed by the second instruction received by the terminal device serviced by the repeater, the repeater does not perform forwarding in the first flexible time unit.

[0151] In some embodiments, the second flexible time unit is determined by a time division duplex configuration of the terminal device, and the first flexible time unit and the second flexible time unit are identical in the time domain, i.e., are the same time domain resource.

[0152] In some embodiments, "matching" means, for example, that a downlink transmission by a repeater in a first flexible time unit coincides with a reception by a terminal device in a second flexible time unit, and / or that an uplink transmission by a repeater in a first flexible time unit coincides with a transmission by a terminal device in a second flexible time unit.

[0153] In some embodiments, "mismatched" means, for example, that downlink forwarding by the repeater in a first flexible time unit does not match with transmission by the terminal device in a second flexible time unit, and / or that uplink forwarding by the repeater in a first flexible time unit does not match with reception by the terminal device in a second flexible time unit.

[0154] The following will be described with reference to a specific example.

[0155] When the repeater receives or detects a first indication to indicate that the repeater performs downlink forwarding on a channel or signal with a set of flexible symbols, e.g. If the repeater receives or detects a DCI fromat indicating that the repeater receives a PDSCH or CSI-RS in this set of symbols, and the terminal device served by the repeater receives or detects a DCI fromat indicating that the terminal device receives a PDSCH or CSI-RS in this set of symbols, the repeater transmits the PDSCH or CSI-RS received from the network device to the terminal device corresponding to the repeater, and / or If the repeater receives or detects a DCI fromat indicating that the repeater receives a PDSCH or CSI-RS on this set of symbols and the terminal device served by the repeater does not receive or detect a DCI fromat indicating that the repeater receives a PDSCH or CSI-RS on this set of symbols, or if the terminal device served by the repeater receives or detects a DCI format or a RAR UL grant or a fallbackRAR UL grant or a successRAR indicating that the terminal device transmits a PUSCH or a PUCCH or a PRACH or an SRS on this set of symbols, the repeater does not perform downlink transmission on this set of symbols.

[0156] When the repeater receives or detects a first indication that the repeater is to perform uplink forwarding on a channel or signal with a set of flexible symbols, e.g. If the repeater has received or detected a DCI fromat or RAR UL grant or fallbackRAR UL grant or successRAR indicating that the repeater transmits a PUSCH or PUCCH or PRACH or SRS in this set of symbols, and a terminal device served by the repeater receives or detects a DCI fromat or RAR UL grant or fallbackRAR UL grant or successRAR indicating that the repeater transmits a PUSCH or PUCCH or PRACH or SRS in this set of symbols, the repeater transmits the PPUSCH or PUCCH or PRACH or SRS received from the terminal device to the network device, and / or If the repeater receives or detects a DCI fromat or RAR UL grant or fallbackRAR UL grant or successRAR indicating that a PUSCH, PUCCH, PRACH or SRS is transmitted on this symbol set, and a terminal device served by the repeater does not receive or detect a DCI fromat or RAR UL grant or fallbackRAR UL grant or successRAR indicating that a PUSCH, PUCCH, PRACH or SRS is transmitted on this symbol set, or if the terminal device served by the repeater receives or detects a DCI format indicating that a PDSCH or CSI-RS is received on this symbol set, the repeater does not perform uplink transmission on this symbol set.

[0157] In some embodiments, when a repeater-only time division duplex configuration is configured for a symbol in a flexible area unit indicated by a cell-wide time division duplex configuration, the repeater does not expect to simultaneously receive repeater-only time division duplex configuration signaling configured as a transmit signal and repeater-only time division duplex configuration signaling configured as a receive signal.

[0158] As mentioned above, the time division duplex configuration of the repeater includes a semi-static time division duplex configuration and / or a dynamic time division duplex configuration.

[0159] In some embodiments, if a semi-static time division duplex configuration is configured for the repeater: If the repeater is not configured to detect the dynamic time division duplex configuration and the group of symbols of the slot configured by the cell-wide time division duplex configuration and the repeater-specific time division duplex configuration is flexible, or if the cell-wide time division duplex configuration and the repeater-specific time division duplex configuration are not provided for the repeater, when the repeater receives an associated instruction for uplink forwarding, the repeater performs uplink forwarding, and / or when the repeater receives an associated instruction for downlink forwarding, the repeater performs downlink forwarding.

[0160] For example, if the repeater is not configured to detect a dynamic time division duplex configuration, such as a PDCCH carrying DCI format 2_0, and the cell-wide time division duplex configuration and the repeater-specific time division duplex configuration provided for the symbols in the slot are flexible, or if semi-static common and specific configurations for the repeater are not provided, When the repeater receives or detects an indication corresponding to the DCI format, the repeater receives a PDSCH or CSI-RS, or transmits a PDSCH or CSI-RS received from the terminal device to the corresponding terminal device; When the repeater receives or detects an indication corresponding to DCI fromat or RAR UL grant or fallbackRAR UL grant or successRAR, the repeater transmits a PUSCH or PUCCH or PRACH or SRS, or the repeater transmits a PUSCH or PUCCH or PRACH or SRS received from the terminal device to the terminal device.

[0161] In some embodiments, if a dynamic time division duplex configuration is configured for the repeater, When the group of symbols of the slots configured by the cell-wide time division duplex configuration and the repeater-specific time division duplex configuration for the repeater is flexible, or when the cell-wide time division duplex configuration and the repeater-specific time division duplex configuration are not provided for the repeater, and a slot format provided by the dynamic time division duplex configuration is detected, and the slot format is not a 255 format; When the repeater receives or detects a first instruction instructing the repeater to perform an uplink transmission or a downlink transmission on the symbol of the slot, the repeater performs an uplink transmission or a downlink transmission on the symbol of the slot; and / or When the repeater does not receive or detect a first instruction instructing the repeater to perform an uplink transmission in a symbol of the slot, or a first instruction instructing the repeater to perform a downlink transmission in a symbol of the slot, the repeater does not perform an uplink transmission or a downlink transmission in the symbol of the slot.

[0162] For example, if the cell-wide time division duplex configuration and the repeater-specific time division duplex configuration in which the set of symbols in the slot designated for the repeater is provided are flexible, or if the cell-wide time division duplex configuration and the repeater-specific time division duplex configuration are not provided for the repeater, and the repeater detects a dynamic TDD configuration, for example, DCI format 2_0, the format of the slot provided by the slot format value is not 255; When one or more of this set of symbols are symbols in the CORESET and the repeater is configured to perform PDCCH monitoring, the repeater receives the PDCCH in the CORESET, or transmits the PDCCH in the CORESET received from the network device to the terminal device corresponding to the repeater, only if the SFI-index value in DCI format 2_0 indicates that the one or more symbols are downlink symbols.

[0163] When the SFI-index value in DCI format 2_0 indicates that this symbol set is flexible and the repeater receives or detects one DCI fromat indicating that it receives PDSCH or CSI-RS on this symbol set, the repeater receives PDSCH or CSI-RS, or transmits PDSCH or CSI-RS received from the network device to the terminal device corresponding to the repeater.

[0164] When the value SFI-index of DCI format 2_0 indicates that this symbol set is flexible, and the repeater receives or detects DCI fromat, RAR UL grant, fallbackRAR UL grant, or successRAR indicating that the repeater transmits PUSCH, PUCCH, PRACH, or SRS in this symbol set, the repeater transmits PUSCH, PUCCH, PRACH, or SRS, or transmits PUSCH, PUCCH, PRACH, or SRS received from the terminal device to the network device; When the value SFI-index of DCI format 2_0 indicates that this symbol set is flexible and the repeater has not received or detected a DCI fromat indicating that it receives a PDSCH or a CSI-RS on this symbol set, or the repeater has not received or detected a DCI fromat or a RAR UL grant or a fallbackRAR UL grant or a successRAR indicating that it transmits a PUSCH or a PUCCH or a PRACH or an SRS on this symbol set, the repeater does not perform transmission or reception on this symbol set, or the repeater does not perform uplink transmission or downlink transmission on this symbol set.

[0165] In some embodiments, if a dynamic time division duplex configuration is configured for the repeater, the method may further include the following steps.

[0166] If a group of symbols of a slot configured by a cell-wide time division duplex configuration and a repeater-specific time division duplex configuration for a repeater is flexible, or if a cell-wide time division duplex configuration and a repeater-specific time division duplex configuration are not provided for a repeater and a dynamic time division duplex configuration does not provide a slot format, when the repeater receives a first instruction, the repeater performs uplink transmission or downlink transmission on the symbols of the slot.

[0167] As described above, in addition to being able to perform forwarding, a repeater according to an embodiment of the present invention can also communicate (also referred to as transmit) with network devices, for example, via a downlink communication link and / or an uplink communication link.

[0168] In some embodiments, it is necessary to consider the relationship between the time division duplex configuration for the repeater to perform communication (transmission) and the time division duplex configuration for the repeater to perform transfer, for example, it is necessary to consider the relationship between communication (transmission) and transfer within a flexible area configured by the repeater. This can avoid collision between transfer and transfer by the repeater within the flexible area, and ensure the reliability of transfer and transmission by the repeater.

[0169] In step 301, the repeater receives time division duplex configuration information from a network device. In some embodiments, the time division duplex configuration information indicates at least one of a downlink time unit, a flexible time unit, and an uplink time unit in which the repeater performs transmission, and / or indicates at least one of a downlink time unit, a flexible time unit, and an uplink time unit in which the repeater performs communication.

[0170] In some embodiments, the same time division duplex configuration information may be used to indicate at least one of the downlink time unit, the flexible time unit, and the uplink time unit in which the repeater performs forwarding and transmission, or different duplex configuration information may be used to indicate at least one of the downlink time unit, the flexible time unit, and the uplink time unit in which the repeater performs forwarding and transmission.

[0171] For example, the time division duplex configuration information indicates at least one of a downlink time unit, a flexible time unit, and an uplink time unit for the repeater to perform transmission, and the time division duplex configuration information indicates at least one of a downlink time unit, a flexible time unit, and an uplink time unit for the repeater to perform communication.

[0172] As another example, a repeater receives first time division duplex configuration information and second time division duplex configuration information, respectively, where the first time division duplex configuration information indicates at least one of a downlink time unit, a flexible time unit and an uplink time unit for the repeater to perform transmission, and the second time division duplex configuration information indicates at least one of a downlink time unit, a flexible time unit and an uplink time unit for the repeater to perform communication.

[0173] In some embodiments, the time division duplex configuration information for transmission may reuse (use) the time division duplex configuration information for communication, or the time division duplex configuration information for transmission and the time division duplex configuration information for communication may be identical, or the time division duplex configuration information for communication may not reuse (use), or the time division duplex configuration information for transmission and the time division duplex configuration information for communication may be different.

[0174] For example, the parameters configured by the time division duplex configuration information for forwarding are "aaabbbxxx", but "aaabbbxxx" is actually the same as the parameters for communication, or the parameters of the time division duplex configuration for the repeater to perform forwarding use the parameters "aaabbbxxx" of the time division duplex configuration for the repeater to perform communication.

[0175] Additionally, "aaabbbxxx" is merely an example of a parameter format and does not limit the format and / or content of the parameters.

[0176] Also, for example, forwarding by a repeater determines a reference SCS based on signaling, and the signaling is actually signaling for the repeater to perform communication.

[0177] The following specifically describes the relationship between the time division duplex configuration in which the repeater performs communication (transmission) and the time division duplex configuration in which the repeater performs transfer.

[0178] In some embodiments, the repeater receives a time division duplex configuration indicating a downlink transmission time unit, an uplink transmission time unit and a flexible time unit for the repeater to perform transmission. The time division duplex configuration received by the repeater uses the time division duplex configuration for the repeater to perform communication, or the time division duplex configuration received by the repeater is the same as the time division duplex configuration for the repeater to perform communication.

[0179] For example, the instruction signaling indicating a forwarding operation in a flexible time unit received or detected by the repeater uses the instruction signaling indicating a communication operation in a flexible time unit received or detected by the repeater, or the instruction signaling indicating a forwarding operation in a flexible time unit received or detected by the repeater is identical to the instruction signaling indicating a communication operation in a flexible time unit received or detected by the repeater.

[0180] Also, for example, the instruction signaling indicating a forwarding operation in a flexible time unit received or detected by the repeater does not use the instruction signaling indicating a communication operation in a flexible time unit received or detected by the repeater, or the instruction signaling indicating a forwarding operation in a flexible time unit received or detected by the repeater is different from the instruction signaling indicating a communication operation in a flexible time unit received or detected by the repeater.

[0181] In some embodiments, the repeater receives a time division duplex configuration indicating a downlink transmission time unit, an uplink transmission time unit and a flexible time unit for the repeater to perform transmission. The time division duplex configuration received by the repeater does not use the time division duplex configuration for the repeater to perform communication, or the time division duplex configuration received by the repeater is different from the time division duplex configuration for the repeater to perform communication.

[0182] For example, the time division duplex configuration signaling for forwarding received by the repeater does not use the time division duplex configuration signaling for the repeater to perform communication, or the time division duplex configuration signaling for forwarding is different from the time division duplex configuration signaling for the repeater to perform communication, the parameters of the time division duplex configuration for forwarding received by the repeater use the parameters of the time division duplex configuration for the repeater to perform communication, or the parameters of the time division duplex configuration for forwarding are the same as the parameters of the time division duplex configuration for the repeater to perform communication.

[0183] Here, for example, the instruction indicating a forwarding operation in the flexible time unit received or detected by the repeater uses an instruction indicating a communication operation in the flexible time unit received or detected by the repeater, or the instruction indicating a forwarding operation in the flexible time unit received or detected by the repeater is the same as the instruction indicating a communication operation in the flexible time unit received or detected by the repeater. For example, the instruction indicating a forwarding operation in the first flexible time unit received or detected by the repeater and the instruction indicating a communication operation received or detected by the repeater are the same DCI fromat.

[0184] Also, for example, the time division duplex configuration signaling for forwarding received by the repeater does not use the time division duplex configuration signaling for the repeater to perform communication, or the time division duplex configuration signaling for forwarding is different from the time division duplex configuration signaling for the repeater to perform communication. The parameters of the time division duplex configuration for forwarding received by the repeater do not use the parameters of the time division duplex configuration for the repeater to perform communication, or the parameters of the time division duplex configuration for forwarding are different from the parameters of the time division duplex configuration for the repeater to perform communication.

[0185] Here, for example, the instruction indicating a forwarding operation in the flexible time unit received or detected by the repeater does not use an instruction indicating a communication operation in the flexible time unit received or detected by the repeater, or the instruction indicating a forwarding operation in the flexible time unit received or detected by the repeater is different from the instruction indicating a communication operation in the flexible time unit received or detected by the repeater. For example, the instruction indicating a forwarding operation in the first flexible time unit received or detected by the repeater and the instruction indicating a communication operation received or detected by the repeater are different DCI fromats.

[0186] In some embodiments, the parameters of the time division duplex configuration for the transmission received by the repeater use the parameters of the time division duplex configuration for the repeater to perform the communication, or the parameters of the time division duplex configuration for the repeater to perform the transmission are the same as the parameters of the time division duplex configuration for the communication.

[0187] In some embodiments, the parameters of the time division duplex configuration for the transmission received by the repeater do not use the parameters of the time division duplex configuration for the repeater to perform the communication, or the parameters of the time division duplex configuration for the repeater to perform the transmission are different from the parameters of the time division duplex configuration for the communication.

[0188] In some embodiments, if both forwarding and communication (transmission) behavior of the repeater needs to be considered, then in step 302 the repeater determines a forwarding behavior and / or a communication behavior in a first flexible time unit.

[0189] In some embodiments, the communication operation includes at least one of an uplink transmission, a downlink transmission, and no transmission between the repeater and the network device.

[0190] For example, uplink transmission includes the repeater sending channels and / or signals to a network device, and downlink transmission includes the repeater receiving channels and / or signals from a network device.

[0191] In some embodiments, downlink transmission includes at least one of the following operations: sequence detection, demodulation, descrambling, decoding, and decrypting information. Uplink transmission includes at least one of the following operations: information generation, sequence generation, scrambling, encoding, modulation, mapping to time-frequency resources, etc.

[0192] In some embodiments, the repeater determines a forwarding and / or communication operation in the first flexible time unit according to a third default rule. For example, the repeater determines whether to perform forwarding and / or communication in the first flexible time unit according to a third default rule.

[0193] As stated above, "default rule" means a predefined rule or convention, such as a convention in a protocol.

[0194] In some embodiments, the third rule is: During a first flexible time unit, the repeater performs communication (transmission) and does not perform forwarding; During a first flexible time unit, the repeater performs forwarding and does not perform communication (transmission); The repeater performs communication (transmission) and forwarding in a first flexible time unit; and The first flexible time unit includes one rule that the repeater does not perform communication (transmission) and forwarding.

[0195] In some embodiments, when performing forwarding in the first flexible time unit and not performing communication, the repeater receives a first signaling, which indicates whether the repeater performs forwarding according to the instruction or according to a default configuration (e.g., similar to the configuration manner of the first rule above).

[0196] For example, a one-bit indication is used, that is, if the first signaling indicates 1, perform forwarding according to the default configuration, and if it indicates 0, determine the forwarding direction according to the indication.

[0197] Also, for example, the first signaling is used to indicate that a default configuration is used, and if the first signaling is provided, the repeater determines the forwarding direction in the first flexible time unit according to the default configuration, and if the first signaling is not provided, the repeater determines the forwarding direction in the first flexible time unit according to the instruction.

[0198] In some embodiments, when performing communication in the first flexible time unit and not performing forwarding, the repeater receives second signaling, which indicates whether the repeater performs communication according to the instruction or according to a default configuration.

[0199] For example, a 1-bit indication is used: if the second signaling indicates 1, communication is performed according to the default configuration; if it indicates 0, the communication direction (transmission direction) is determined according to the indication.

[0200] Also, for example, the second signaling is used to indicate that the default configuration is used. If the second signaling is provided, the repeater determines the communication direction (transmission direction) in the first flexible time unit according to the default configuration, and if the second signaling is not provided, the repeater determines the communication direction (transmission direction) in the first flexible time unit according to the instruction.

[0201] In some embodiments, when performing both forwarding and communication in the first flexible time unit, the repeater receives a first signaling and / or a second signaling, the first signaling indicating whether the repeater performs forwarding according to the instruction or according to a default configuration, and the second signaling indicating whether the repeater performs communication (transmission) according to the instruction or according to a default configuration.

[0202] For example, one bit is used to indicate the direction. If the first signaling / second signaling indicates 1, transfer and / or communication (transmission) is performed according to the default configuration, and if it indicates 0, the transfer direction and / or communication direction (transmission direction) is determined according to the instruction.

[0203] For example, the first signaling and / or the second signaling are used to indicate that a default configuration is used. If the first signaling and / or the second signaling are provided, the repeater determines the forwarding direction and / or communication direction (transmission direction) in the first flexible time unit according to the default configuration, and if the first signaling and / or the second signaling are not provided, the repeater determines the forwarding direction and / or communication direction (transmission direction) in the first flexible time unit according to the instruction.

[0204] In some embodiments, the repeater may determine a forwarding action and / or a communication action in the first flexible time unit based on the forwarding priority and the communication priority.

[0205] In some embodiments, the forwarding priority is determined based on the priority of the terminal device served by the repeater and / or the priority of the service forwarded by the repeater.

[0206] For example, if the transfer priority is higher than the communication priority, the repeater decides to perform only transfer and not communication in the first flexible time unit, or after determining a transfer time region in the first flexible time unit, the repeater decides to determine a communication time region in the remaining region of the first flexible time unit.

[0207] As another example, if the communication priority is higher than the forwarding priority, the repeater decides to perform only communication and not forwarding in the first flexible time unit, or after determining a communication time region in the first flexible time unit, the repeater decides to determine a forwarding time region in the remaining region of the first flexible time unit.

[0208] In some embodiments, high priority means a higher level of priority and low priority means a lower level of priority.

[0209] For example, the smaller the priority number, the higher the priority (level), and the larger the priority number, the lower the priority (level).

[0210] As another example, the higher the priority number, the higher the (level of) priority, and the lower the priority number, the lower the (level of) priority.

[0211] In some embodiments, a repeater may determine a priority for end devices served by the repeater.

[0212] In some embodiments, the repeater may determine the priority of the forwarded service when performing the forwarding.

[0213] According to this embodiment, by sending TDD configuration information to the repeater, the repeater can determine the configured flexible region, and by the repeater determining the forwarding operation in the first flexible time unit, the forwarding of the repeater can be more flexible to sudden service transmission, and a buffer time between downlink forwarding and uplink forwarding can be provided for the repeater, so that the repeater can have enough time to process the received data and prepare to transmit the service.

[0214] In addition, by taking into consideration the configuration relationship between transmission and forwarding in a flexible area configured by a repeater, it is possible to avoid collisions between transmission and forwarding by the repeater in the flexible area and ensure the reliability of transmission and forwarding by the repeater.

[0215] <Example 2> The embodiment of the present invention provides a repeater configuration method, which is applied to a network device. The method corresponds to the repeater configuration method in the first embodiment, and the duplicated description of the similar contents will be omitted. For example, the method is applied to the network device 101 in FIG. 1 and FIG. 2.
