[0018] It should be understood that although the embodiments of the present application have been described using the communication system 100 as an example, the embodiments of the present application are not limited thereto.

In the embodiments of the present application, the "protocol" may be a standard protocol in the communications field, such as the NR protocol and related protocols used in future communications systems, and the present application does not limit the scope of the present application.

[0029] In order to facilitate understanding of the technical solutions of the embodiments of the present application, the related arts of the embodiments of the present application will be described below. Hereinafter, the related arts are optional solutions that can be arbitrarily combined with the technical solutions of the embodiments of the present application, and all of them fall within the protection scope of the embodiments of the present application.

[0030] To enable networks to provide better coverage, especially in the case of FR2, where FR2 millimeter wave signals are easily blocked by vegetation and buildings, more flexible and reliable coverage extension technologies are needed. A related solution is the proposed and standardized smart repeater technology.

[0031] As shown in Figure 2, the smart repeater is located between the base station and the terminal. Compared with the conventional smart repeater, the smart repeater has the function of beam management. The standardization goal is that the smart repeater is transparent to the terminal. Table 1 below distinguishes between the smart repeater and the conventional smart repeater. [Table 1]

[0032] In conventional smart repeaters, the uplink and downlink are simultaneously power amplified for the frequency division duplexing (FDD) frequency band, mainly by frequency separation to avoid the self-excitation effect of the smart repeater. Smart repeaters focus on FR2, which is mostly in the FDD frequency band. To better configure the uplink and downlink operations of the base station, the smart repeater must perform the amplification and forwarding operations of the uplink and downlink respectively based on the uplink and downlink time slots set by the base station. The smart repeater requires information about the time slots set by the base station.

[0033] Most traditional smart repeaters in FR1 use directional or omnidirectional beams. For example, a smart repeater can receive signals from outside a building (through a glass window) and transmit them to users inside the building (through a glass window). Traditional smart repeaters lack the ability to perform flexible beam management. In contrast, smart repeaters focus on FR2 and must incorporate beam management capabilities to direct the beam toward users for directional amplification and transmission. At the same time, the beam direction can also help to avoid the self-oscillating effect of smart repeaters to some extent.

[0034] From the protocol stack perspective, conventional smart repeaters only have radio frequency channels and directly amplify and forward data. For data, smart repeaters only have a radio frequency section that amplifies and forwards data, without analyzing, repackaging, or forwarding the data. However, to better coordinate with the base station's uplink and downlink and perform beam management tasks, the UE section of the smart repeater needs to have certain protocol stack functionality.

[0035] Because the smart repeater only forwards data, it does not know how many users it serves. Similarly, it does not know when the base station will schedule users because it does not analyze the PDCCH and data it 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 or 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 for the smart repeater to provide better service to users, it is first necessary to determine when the smart repeater should serve 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 also necessary to solve the problem of the smart repeater serving multiple users at the same time.

[0038] Based on the relationship between the beam and the time slot, one approach is to use Radio Resource Control (RRC) to semi-statically configure whether a specific time slot is used for the smart repeater's forwarding task. However, this approach limits the user scheduling of the smart repeater and may not be able to proactively respond to unexpected service requests. Therefore, a more flexible instruction or scheduling method is needed. Similarly, a relatively dynamic and flexible instruction method also requires solving the problem of which direction or which user to direct the beam, since the smart repeater cannot analyze the downlink signal of the base station it is forwarding (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 facilitate understanding of the technical solutions of the embodiments of the present application, the technical solutions of the present application will be described in detail below through specific examples. The above related technologies can be arbitrarily combined with the technical solutions of the embodiments of the present application as optional technical solutions, and all of them 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 time domain resources provided by an embodiment of the present application. As shown in FIG. 3, the method for determining time domain resources 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 uplink backhaul and / or at least one downlink time domain resource used for downlink backhaul, and the network node receives the first signaling sent from the base station.

[0043] In the embodiments of the present application, the network node may be a smart repeater, for example, may be called a smart repeater / relay, and 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 a base station, or a network node being in an uplink forwarding state, whereby when a 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 upper node to a lower node or terminal, or a network node being in a downlink forwarding state, where when a 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; the uplink time domain resource and the downlink time domain resource having the 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 also be a beam, an instruction related to a beam, 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, wherein the first transmission configuration sets the number of beams or spatial filter configurations 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 configurations for which the network node serves a user, or the first transmission configuration sets the number of spatial filter configurations 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 time slots 1, 2, 3, 4, 5, and 6 to be used for backhaul through RRC, where time slots 1, 2, and 3 are downlink time slots used for downlink backhaul, and time slots 4, 5, and 6 are uplink time slots used for uplink backhaul. Here, time slot 1 and time slot 4 use the beam of the same network node, i.e., there is a correspondence (or association) relationship between time slot 1 and time slot 4. Optionally, a periodic configuration scheme is used for the time slots 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, and 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 for 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, which indicates that the time length of the offset of the first time domain resource relative to the time domain resource on which the second signaling is located is M time domain resources, where M is an integer greater than or equal to 0, and the time length is less than or equal to a period 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 it takes for the network node to switch its working state.

[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 the uplink resource indicated by the second information; or The method further includes the step of the network node transmitting HARQ-ACK information in the closest one 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 directions, where the spatial information is a beam direction, a beam state, a transmission setting, a transmission setting instruction, or spatial filter information. Specific implementations of the third information are described below.

[0063] Realization 1) In some alternative 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] Implementation 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, in 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, and the resource type is an uplink time domain resource or a downlink time domain resource. In 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 the 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, through third information, a second time domain resource or first spatial information associated with the first time domain resource; an uplink time domain resource associated with 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, through third information, a second time domain resource or first spatial information associated with the first time domain resource; a downlink time domain resource associated with 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 downlink time domain resource next to 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] Furthermore, 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, through third information, a second time domain resource associated with the first time domain resource and a fourth time domain resource associated with the third time domain resource, wherein: 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] Note that 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, a base station dynamically instructs a network node to perform backhaul in one of the time slots (referred to as time slot X) using a 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 must be equal to or greater than the sum of at least one or more of the DCI processing time, the beam adjustment time, and the time for the network node to switch its working state. Here, the beam adjustment time may be the time indicated by the parameter timeDurationForQCL. The time for the network node to switch its working state refers to the time for the network node to switch from non-forwarding to forwarding (e.g., PA switch time or uplink-downlink switch time). X must be smaller than the period of the time slot used for backhaul configured by the RRC configuration information. Here, as one option, if the timeslot indicated by the DCI is an uplink timeslot, it indicates that the backhaul of the timeslot is an uplink backhaul, and if the timeslot indicated by the DCI is a downlink timeslot, it indicates that the backhaul of the timeslot 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 timeslot 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 configurations configured 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 single user uplink data transmission, for example, feeding back ACK indicates that the network node has correctly received the DCI.

[0076] For example, the base station may determine beam or timeslot information of a network node associated with the terminal based on CSI-RS ID information fed back by the CSI-RS RSRP of the terminal, or may determine beam or timeslot information of a network node associated with the terminal based on SSB measurement and time information (e.g., RACH occasion) of uplink PRACH transmission. Option 1) The base station directly indicates one of six timeslots (configured by RRC). For example, when indicating one of the six timeslots using 3-bit information, this indicates that the beam used by timeslot X indicated by the DCI and the timeslot indicated in the 3-bit information have the same spatial relationship (spatial state or TCI state) or use the same beam. If the timeslot indicated by the 3-bit information is an uplink timeslot, the timeslot X indicated by the DCI is a timeslot used for uplink backhaul, and if the timeslot indicated by the 3-bit information is a downlink timeslot, the timeslot X indicated by the DCI is a timeslot used for downlink backhaul. For example, if 3 bits indicate time slot 1 (time slot 1 is a downlink time slot), it means that the backhaul of time slot X and time slot 1 have the same beam direction or transmission state (e.g., transmission setting or transmission setting indication), and the uplink / downlink transmission direction of time slot X is also the same as time slot 1. Option 2) The base station configures the corresponding uplink and downlink beam states of the network node through RRC, for example, beam state 1, state 2, and 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 also needs to indicate whether the backhaul of time slot X is an uplink backhaul or a downlink backhaul.Option 3), the base station configures the corresponding uplink and downlink beam states, such as beam states 1, 2, and 3, in the network node through RRC, and the DCI indicates the beam state configured by the RRC, which is the beam state that the network node uses 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, for example, one is downlink timeslot X and the other is uplink timeslot Y, then, in option 1), if timeslot X is associated with timeslot 1 configured by RRC, timeslot Y uses the same beam or spatial state as timeslot 1. In option 2), if timeslot X is associated with timeslot 1 configured by RRC, timeslot Y is associated with timeslot 2 (downlink timeslot) or timeslot 5 (uplink timeslot) configured by RRC, and the beam direction or spatial state of timeslot 2 and timeslot 5 is different from that of timeslot 1. Option 3) In the case where the DCI simultaneously indicates time slot X and time slot Y but indicates only one beam status information, it indicates that the downlink of time slot X is a downlink time slot under the beam status, and time slot Y is an uplink beam under the beam status. Note that with regard to the beam direction and / or uplink / downlink transmission direction, the time slot indicated by the DCI can overwrite the time slot set by conventional RRC. The goal is to update the beam direction of some time slot 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 Figure 4, the base station configures time slots 1, 2, 3, and 4 used for downlink backhaul through RRC, and downlink time slots 1, 2, 3, and 4 correspond to uplink time slots 1, 2, 3, and 4 used for uplink backhaul. Downlink time slot 1 and uplink time slot 1 have the same beam direction or transmission configuration or setting instruction. The base station instructs the network node through DCI (located in time slot 0) to configure corresponding time slot 10 and time slot 16, and the associated RRC time slot #1. If backhaul is not currently performed in time slot 10, backhaul is performed in time slot 10 according to the instruction of DCI. Time slot 10 indicated by the DCI and time slot #1 configured by RRC have the same beam direction, so that the beam direction of time slot 10 is the same as time slot #1 initially configured by RRC. The network node performs uplink backhaul in time slot 16, and the direction in which it receives the uplink beam is the same as the beam direction used by time slot #1, or the same as the beam direction of uplink time slot #1 corresponding to time slot #1.

[0080] The technical solution of the embodiments of the present application solves the problems 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, when the network node is transparent, the base station dynamically instructs the network node on uplink and downlink time slots and corresponding beam directions. The base station dynamically instructs the network node to perform uplink or downlink backhaul in time slots that are not originally used for beam forwarding. By instructing the beam direction based on the instructed relevant time slot or the beam status set by RRC, the network node can perform backhaul in the required direction.
