For example, the predefined may be defined in a protocol. In addition, in the embodiment of the present application, the "protocol" may be a standard protocol in the communication field, for example, including the NR protocol and associated protocols used in future communication systems, and the present application does not limit this.

[0029] In order to facilitate understanding of the technical solutions of the embodiments of the present application, the relevant technologies of the embodiments of the present application will be described below. In the following, the relevant technologies are optional solutions that may be arbitrarily combined with the technical solutions of the embodiments of the present application, all of which fall within the protection scope of the embodiments of the present application.

[0030] In order to enable the network to provide better coverage, especially for FR2, where the mmWave signal is easily blocked by vegetation and buildings, a more flexible and reliable coverage extension technology is needed. In the related solution, smart repeater technology is proposed and standardized.

[0031] As shown in Figure 2, the smart repeater is located between the base station and the terminal, and compared with the traditional smart repeater, the smart repeater has the function of beam management, and the standardization goal is that the smart repeater is transparent to the terminal. The following Table 1 gives the distinction between the smart repeater and the traditional smart repeater. [Table 1]

[0032] In the traditional smart repeater, for the frequency band of Frequency Division Duplexing (FDD), the uplink and downlink perform power amplification at the same time, mainly by frequency separation to avoid the self-excitation effect of the smart repeater. The smart repeater pays attention to FR2, and most of FR2 is in the FDD frequency band. In order to better set the uplink and downlink work of the base station, the smart repeater needs to perform the amplification and forwarding work of the uplink and downlink respectively based on the uplink and downlink time slots set by the base station. The smart repeater needs the time slot information set by the base station.

[0033] Most of the traditional smart repeaters in FR1 use directional beams or omnidirectional beams. For example, the smart repeater receives signals outside the building (outside the glass window) and transmits them directional to the users inside the building (glass window). Traditional smart repeaters cannot perform flexible beam management tasks. In contrast, smart repeaters focus on FR2 and need to introduce beam management functions, so that the beam can be directed to the users to perform directional amplification and forwarding tasks. At the same time, the beam direction avoids the self-excitation effect of the smart repeater to a certain extent.

[0034] From the perspective of protocol stack, the traditional smart repeater only has a radio frequency channel and directly amplifies and forwards. As for data, the smart repeater only has a radio frequency part, amplifies and forwards data, and does not analyze, repackage and forward data. However, in order to better cooperate with the uplink and downlink of the base station and perform beam management operations, the UE part of the smart repeater is desired to have a certain protocol stack function.

[0035] Since the smart repeater only forwards data, the smart repeater does not know how many users it serves, and similarly, the smart repeater does not know when the base station will schedule users, since it does not analyze the PDCCH and data that the smart repeater provides to users from the base station.

[0036] A smart repeater cannot perform beam management for the users it serves: on the one hand, it does not generate signals to transmit to its attached users, and on the other hand, it does not know the number of attached users, nor the related user information. A smart repeater achieves the purpose of beam management by only forwarding the signals of a base station or a terminal.

[0037] Based on the above, in order to enable the smart repeater to provide better service to users, it is first necessary to determine when the smart repeater serves the base station and the terminal, and how to recognize the user when the user information is not analyzed. At the same time, it is necessary to solve the problem that the smart repeater serves multiple users at the same time.

[0038] Based on the relationship between the beam and the time slot, one embodiment is to perform semi-static configuration by Radio Resource Control (RRC) to indicate whether a specific time slot is used for the forwarding operation of the smart repeater. However, in this case, the scheduling of users in the smart repeater is limited, and it may not be possible to proactively respond to sudden service occurrences, so a more flexible indication or scheduling method is required. Similarly, a relatively dynamic and flexible indication method also needs to solve the problem of which direction or which user to direct the beam, since the smart repeater cannot analyze the downlink signal of the forwarding base station (because the downlink signal is transparent to the smart repeater).

[0039] Therefore, the following technical solutions are proposed in the embodiments of the present application.

[0040] In order to easily understand the technical solutions of the embodiments of the present application, the technical solutions of the present application are described in detail below through specific examples. The above related technologies are optional technical solutions that can be arbitrarily combined with the technical solutions of the embodiments of the present application, all of which fall within the scope of protection of the embodiments of the present application. The embodiments of the present application include at least some of the following contents:

[0041] FIG. 3 is a flowchart of a method for determining a time domain resource provided by an embodiment of the present application. As shown in FIG. 3, the method for determining a time domain resource includes the following steps 301 to 302.

[0042] Step 301: A base station sends first signaling to a network node for configuring at least one time domain resource, including at least one uplink time domain resource used for an uplink backhaul and / or at least one downlink time domain resource used for a downlink backhaul, and the network node receives the first signaling sent from the base station.

[0043] In the embodiment of the present application, the network node may be a smart repeater, for example, may be called a smart repeater / relay. The network node may be understood as a smart repeater / relay controlled by the network.

[0044] In an embodiment of the present application, a network node receives first signaling transmitted from a base station, and in some alternative embodiments, the first signaling may be RRC configuration information, where the first signaling configures at least one time domain resource, the at least one time domain resource including at least one uplink time domain resource used for uplink backhaul and / or at least one downlink time domain resource used for downlink backhaul.

[0045] Here, the time domain resource may be one or more time slots, or may be one or more codes.

[0046] Here, the uplink backhaul refers to a network node forwarding (amplifying and transmitting) uplink data or uplink signals transmitted by a terminal to an upper node or base station, or the network node being in an uplink forwarding state, where when the network node is in an uplink forwarding state, there may be no actual transmission of uplink data or uplink signals.

[0047] Here, the downlink backhaul refers to a network node forwarding (amplifying and transmitting) downlink data or downlink signals of a base station or an upper node to a lower node or a terminal, or the network node being in a downlink forwarding state, where when the network node is in a downlink forwarding state, there may be no actual transmission of downlink data or downlink signals.

[0048] In some alternative embodiments, the at least one time domain resource is configured periodically in the time domain.

[0049] In some alternative embodiments, the first signaling comprises: spatial information corresponding to each of the at least one uplink time domain resource; spatial information corresponding to each of the at least one downlink time domain resource; is used to set at least one of an association relationship between the at least one uplink time domain resource and the at least one downlink time domain resource, and the uplink time domain resource and the downlink time domain resource having an association relationship correspond to the same spatial information, or the spatial information has a corresponding relationship; Here, the spatial information is a beam direction, a beam state, a transmission setting, a transmission setting instruction, or spatial filter information. The spatial information may be a beam, or an instruction related to a beam, or a spatial relation, or a spatial (transmit or receive) filter.

[0050] In some alternative embodiments, the network node reports a first transmission configuration to the base station, and the base station receives the first transmission configuration reported by the network node, where the first transmission configuration sets the number of beams or spatial filter settings of a Distribute Unit (DU) or a Radio Frequency Unit, or the first transmission configuration sets the number of beams for which the network node performs downlink beam scanning, or the first transmission configuration sets the number of beams or spatial filter settings for which the network node serves a user, or the first transmission configuration sets the number of spatial filter settings for which the network node performs downlink transmission or uplink transmission.

[0051] In some alternative embodiments, the first transmission configuration is used by the base station to determine at least one uplink time domain resource to be used for uplink backhaul and / or at least one downlink time domain resource to be used for downlink backhaul.

[0052] As an example, the base station configures timeslots 1, 2, 3, 4, 5, and 6 to be used for backhaul through RRC, where timeslots 1, 2, and 3 are downlink timeslots used for downlink backhaul, respectively, and timeslots 4, 5, and 6 are uplink timeslots used for uplink backhaul, respectively. Here, timeslot 1 and timeslot 4 use the beam of the same network node, i.e., there is a corresponding (or associated) relationship between timeslot 1 and timeslot 4. Optionally, a periodic configuration scheme is used for the timeslots available for backhaul configured by RRC.

[0053] Step 302: The base station transmits second signaling to the network node instructing the network node to perform backhaul in a first time domain resource, and the network node receives the second signaling transmitted from the base station.

[0054] In an embodiment of the present application, the network node receives second signaling transmitted from the base station, in some alternative embodiments the second signaling is Downlink Control Information (DCI) or is carried by a Media Access Control Control Element (MAC CE), where the second signaling instructs the network node to perform backhaul in a first time domain resource.

[0055] In some alternative embodiments, the reference point or starting point of calculation of the first time domain resource is the time domain resource in which the second signaling is located or the time domain resource after an offset has been superimposed on the time domain resource in which the second signaling is located.

[0056] In one implementation, the second signaling carries first information, the first information indicating a time length of an offset of the first time domain resource relative to a time domain resource in which the second signaling is located is M time domain resources, where M is an integer equal to or greater than 0, where the time length is less than or equal to a periodicity of the plurality of time domain resources.

[0057] Here, optionally, the time length is equal to or greater than the sum of at least one or more of the processing time of the second signaling, the beam adjustment time, and the time for the network node to switch working states.

[0058] Here, the beam adjustment time may be the time indicated by the parameter timeDurationForQCL or the adjustment time of the transmission setting.

[0059] In some alternative embodiments, the second signaling carries second information indicating uplink resources to be used by the network node for transmitting HARQ-ACK information, and the method further comprises: the network node transmitting HARQ-ACK information on uplink resources indicated by the second information; or The method further includes the step of the network node transmitting HARQ-ACK information in the nearest one time time domain resource used for uplink backhaul after receiving the second signaling.

[0060] Here, the HARQ-ACK information is used to indicate whether the second information is correctly received or detected.

[0061] Specifically, if the network node correctly receives or detects the second signaling, it sets the HARQ-ACK information to an ACK value; or, if the network node does not correctly receive or detect the second signaling, it sets the HARQ-ACK information to a NACK value.

[0062] In some alternative embodiments, the second signaling carries spatial information corresponding to the first time domain resource and / or third information indicating uplink-downlink transmission direction, where the spatial information is a beam direction or a beam state or a transmission setting or a transmission setting indication or spatial filter information. A specific implementation of the third information is described below.

[0063] Realization form 1) In some optional embodiments, the third information indicates a second time domain resource within the plurality of time domain resources, where spatial information corresponding to the first time domain resource is the same as spatial information corresponding to the second time domain resource, and an uplink-downlink transmission direction corresponding to the first time domain resource is the same as an uplink-downlink transmission direction corresponding to the second time domain resource.

[0064] Realization 2) In some alternative embodiments, the third information indicates first spatial information among a plurality of spatial information supported by the network node, and the spatial information corresponding to the first time domain resource is the first spatial information. Further, option 1), an uplink-downlink transmission direction corresponding to the first time domain resource is determined based on a configured resource type of the first time domain resource, the resource type being an uplink time domain resource or a downlink time domain resource. Option 2), the third information further indicates an uplink-downlink transmission direction corresponding to the first time domain resource, and the uplink-downlink transmission direction corresponding to the first time domain resource is determined based on the third information.

[0065] In an embodiment of the present application, the first time domain resource indicated by the second signaling may be a downlink time domain resource or an uplink time domain resource. Hereinafter, the solution of the embodiment of the present application will be described by combining these two cases.

[0066] In case 1), the first time domain resource is a downlink time domain resource, and the second signaling indicates a second time domain resource or first spatial information related to the first time domain resource through third information; An uplink time domain resource related to the first time domain resource is the second time domain resource or an uplink time domain resource corresponding to the first spatial information; or an uplink time domain resource associated with the first time domain resource is a next uplink time domain resource of the first time domain resource; Here, the first time domain resource has the same or related spatial information as its associated uplink time domain resource.

[0067] In case 2), the first time domain resource is an uplink time domain resource, and the second signaling indicates a second time domain resource or first spatial information related to the first time domain resource through third information; A downlink time domain resource related to the first time domain resource is the second time domain resource or a downlink time domain resource corresponding to the first spatial information; or a downlink time domain resource associated with the first time domain resource is a next downlink time domain resource of the first time domain resource; Here, the first time domain resource has the same or related spatial information as its associated downlink time domain resource.

[0068] Moreover, in some alternative embodiments, the second signaling further instructs the network node to perform backhaul on a third time domain resource, where, optionally, the first time domain resource is a downlink time domain resource and the third time domain resource is an uplink time domain resource, or the first time domain resource is an uplink time domain resource and the third time domain resource is a downlink time domain resource.

[0069] Solution A): The second signaling indicates a second time domain resource through third information, where the spatial information of the first time domain resource and the spatial information of the third time domain resource are the same as the spatial information of the second time domain resource.

[0070] Solution B): the second signaling indicates first spatial information through third information, where the spatial information of the first time domain resource and the spatial information of the third time domain resource are the same as the first spatial information.

[0071] Solution C), the second signaling indicates a second time domain resource related to the first time domain resource and a fourth time domain resource related to the third time domain resource through third information, where: The spatial information of the first time domain resource is the same as the spatial information of the second time domain resource, and the spatial information of the third time domain resource is the same as the spatial information of the fourth time domain resource.

[0072] Solution D), the second signaling indicates, through third information, first spatial information associated with the first time domain resource and second spatial information associated with the third time domain resource, where the spatial information of the first time domain resource is the same as the first spatial information, and the spatial information of the third time domain resource is the same as the second spatial information.

[0073] In an embodiment of the present application, spatial information corresponding to the first time domain resource determined based on the first signaling is overwritten based on spatial information corresponding to the first time domain resource determined by the second signaling.

[0074] In addition, the above-mentioned overwriting means that spatial information indicated by the third information is currently used based on the time domain resource indicated by the second signaling, and for other resources not indicated by the second signaling, spatial information corresponding to the first time domain resource still determined based on the first signaling is used.

[0075] As an example, the base station dynamically instructs the network node to perform backhaul in any time slot (called time slot X) by DCI. The reference point of time slot X is the time slot in which the DCI is located, and X indicates the Xth time slot after the time slot in which the DCI is located. Here, X needs to be equal to or greater than the sum of at least one or more of the following: the processing time of DCI, the beam adjustment time, and the time for the network node to perform working state switching. Here, the beam adjustment time may be the time indicated by the parameter timeDurationForQCL. The time for the network node to perform working state switching refers to the time for the network node to switch from non-forwarding to forwarding (e.g., the switch time of PA or the switch time of uplink-downlink). X needs to be smaller than the period of the time slot used for backhaul configured by the RRC configuration information. Here, as one option, if the time slot indicated by the DCI is an uplink time slot, it indicates that the backhaul of the time slot is an uplink backhaul, and if the time slot indicated by the DCI is a downlink time slot, it indicates that the backhaul of the time slot is a downlink backhaul. As another option, if the DCI further indicates an uplink or a downlink, it can be determined whether the backhaul of the time slot indicated by the DCI is an uplink backhaul or a downlink backhaul based on the uplink or downlink indicated in the DCI, where the uplink or downlink indicated in the DCI may be different from the uplink and downlink transmission settings set by the base station. The network node can feed back HARQ-ACK information in the uplink resource indicated by the DCI, for example, feeding back an ACK indicates that the network node has correctly received the DCI.Alternatively, the network node may feed back HARQ-ACK information at the time of the nearest one of the user's uplink data transmissions, for example, feeding back an ACK indicates that the network node has correctly received the DCI.

[0076] As an example, the base station may determine beam or time slot information of the network node associated with the terminal based on the id information of the CSI-RS fed back by the CSI-RS RSRP of the terminal, or may determine beam or time slot information of the network node associated with the terminal based on the measurement of the SSB and the time information (e.g., RACH occasion) of the uplink PRACH transmission. Option 1), the base station directly indicates any one of the six time slots (configured by RRC), and when indicating any one of the time slots using, for example, 3-bit information, it indicates that the beam used by the time slot X indicated by the DCI and the time slot indicated in the 3-bit information have the same spatial relationship (spatial state or TCI state) or use the same beam. If the time slot indicated by the 3-bit is an uplink time slot, the time slot X indicated by the DCI is a time slot used for uplink backhaul, and if the time slot indicated by the bit is a downlink time slot, the time slot X indicated by the DCI is a time slot used for downlink backhaul. For example, when 3 bits indicate timeslot 1 (timeslot 1 is a downlink timeslot), it indicates that the backhaul of timeslot X and timeslot 1 have the same beam direction or transmission state (e.g., transmission setting or transmission setting indication), and the uplink / downlink transmission direction of timeslot X is also the same as timeslot 1. Option 2) The base station sets uplink and downlink beam states corresponding to the network node through RRC, e.g., beam state 1, state 2, state 3, where states 1, 2, and 3 represent multiple different beam directions or beams of the network node, and these beams are used for transmitting in different directions of downlink or receiving in different directions of uplink, and the DCI needs to further indicate whether the backhaul of timeslot X is an uplink backhaul or a downlink backhaul.Option 3), the base station configures the corresponding uplink and downlink beam states, e.g., beam states 1, 2, 3, to the network node through RRC, and the DCI indicates the beam state configured by the RRC, where the indicated beam state is that the network node is used for backhaul. The network node determines whether the corresponding backhaul is an uplink backhaul or a downlink backhaul according to the uplink and downlink of the time slot in which the time slot X indicated by the DCI is located.

[0077] As an example, if timeslot X is a downlink timeslot and is associated with timeslot 1 or beam state 1 (one state may correspond to a pair of uplink and downlink timeslots), the corresponding uplink may be the uplink timeslot corresponding to timeslot 1 or state 1 (or the next or nearest next uplink timeslot). If the DCI uses two timeslots simultaneously, e.g. one is downlink timeslot X and the other is uplink timeslot Y, option 1), if timeslot X is associated with RRC configured timeslot 1, timeslot Y uses the same beam or spatial state as timeslot 1. option 2), if timeslot X is associated with RRC configured timeslot 1, timeslot Y is associated with RRC configured timeslot 2 (downlink timeslot) or timeslot 5 (uplink timeslot), and the beam direction or spatial state of timeslot 2 and timeslot 5 is different from timeslot 1. Option 3), DCI indicates timeslot X and timeslot Y at the same time, but indicates only one beam status information, which indicates that the downlink of timeslot X is a downlink timeslot under the beam status, and timeslot Y is an uplink beam under the beam status. Note that for the beam direction and / or uplink-downlink transmission direction, the timeslot indicated by DCI can overwrite or override the timeslot set by conventional RRC. The goal is to update the beam direction of some timeslot settings or expedite the execution of certain transmissions according to the needs of service priority.

[0078] The technical solutions of the embodiments of the present application will be described below in combination with specific application examples.

[0079] As shown in FIG. 4, the base station configures timeslots 1, 2, 3, 4 used for downlink backhaul through RRC, and the downlink timeslots 1, 2, 3, 4 correspond to uplink timeslots 1, 2, 3, 4 used for uplink backhaul. Downlink timeslot 1 and uplink timeslot 1 have the same beam direction or transmission configuration or configuration instruction. The base station instructs the network node through DCI (located in timeslot 0) to configure corresponding timeslot 10 and timeslot 16, and associated RRC timeslot #1. If backhaul is not performed in the conventional timeslot 10, backhaul is performed in timeslot 10 according to the instruction of DCI, and the timeslot 10 instructed by DCI and the timeslot #1 configured by RRC have the same beam direction, so that the beam direction of timeslot 10 is the same as the timeslot #1 initially configured by RRC. The network node performs uplink backhaul in timeslot #16, and the direction in which the uplink beam is received is the same as the beam direction used by timeslot #1, or the same as the beam direction of uplink timeslot #1 corresponding to timeslot #1.

[0080] The technical solution of the embodiment of the present application solves the problem of downlink beam management and serving multiple users when the network node cannot analyze the control information from the base station to the terminal. Based on the reference signal transmitted from the base station, for the case where the network node is transparent, the base station dynamically instructs the network node on the uplink and downlink time slots and the corresponding beam directions. The base station schedules the network node to perform uplink or downlink backhaul in the time slot where the beam forwarding is not originally performed according to the dynamic instruction. By instructing the beam direction according to the instructed related time slot or the beam state set by the RRC, the network node can perform backhaul in the required direction.
