Description

[0001] This application is a divisional application of the case with the application number 202380009525.9, the application date of March 24, 2023, and the invention title "Methods and Apparatuses for Nodes Used in Wireless Communications". Technical Field

[0002] This application relates to the field of communication technologies, and more particularly, to a method and an apparatus for a node used in wireless communications. Background Art

[0003] In order to improve the coverage of a network and support the rapidly increasing number of users, some new types of network nodes have been gradually proposed. Such new types of network nodes can increase the flexibility of network deployment and thus have received more and more attention. For example, some communication systems have introduced relay nodes that can amplify and forward wireless signals between user equipment (UE) and a base station. The relay node can be, for example, a network-controlled repeater (NCR).

[0004] In a scenario where a relay node is deployed, in order to improve the spatial directivity of the relay node's forwarding, the base station can perform beam indication to the relay node. When the base station performs beam indication to the relay node by combining indication beam information and a time-domain resource set, due to the load limitation of the indication signaling, there may be multiple different beam information corresponding to some time-domain resources, resulting in beam indication conflicts, causing confusion in the operation of the relay node, or increasing the power consumption of the relay node, or increasing the signaling overhead, or increasing the transmission delay, or reducing the accuracy of beam indication, or reducing the system transmission quality.

[0087] New network node in a communication system

[0088] Under the trend of network densification and millimeter wave (mmW) communication applications, in order to improve the network coverage ability and support the rapidly growing number of users, some new types of network nodes have been gradually proposed. Such new types of network nodes can increase the flexibility of network deployment and thus have received more and more attention.

[0089] For example, the NR Rel-16 (release-16) version introduces an integrated access and backhaul (IAB) node. This IAB node has been further enhanced in the NR Rel-17 (release-17) version. The biggest feature of this IAB node is that there is no need to set up a wired backhaul link between network nodes.

[0090] For another example, the wireless repeater widely used in 2G, 3G, and 4G systems also belongs to a relatively new type of network node other than the base station. The wireless repeater can also be called a radio frequency repeater (RF repeater) or a relay. The traditional wireless repeater simply amplifies and forwards the received signal. Although this type of wireless repeater has simple functions and high cost-effectiveness, it cannot be flexibly adjusted according to the actual situation of the communication system, so its performance is poor. Compared with the traditional wireless repeater, some communication systems have introduced NCR. NCR increases the ability to receive and process side control information (SCI) from network devices. Based on SCI, NCR can efficiently perform the functions of signal amplification and forwarding, reduce unnecessary noise amplification, so that the reception and transmission of NCR have better spatial directivity, and simplify network integration. The study item (SI) of NCR was carried out in the NR Rel-18 (release-18) version. In September 2022, 3GPP passed RP-222673 and started the "NR NCR" work item (WI) in NR Rel-18, thus officially launching the standardization work of NCR in the NR system.

[0091] According to the research report of NCR (3GPP TR38.867), such as Figure 2As shown, the NCR 130 mainly includes two functional modules: a Network Control Relay - Mobile Termination (NCR-MT) 131 and a Network Control Relay - Forwarding (NCR-Fwd) 132. The NCR-MT 131 is responsible for interacting with the base station 110 to exchange SCI via a control link (C-link). The NCR-Fwd (NCR-forwarding) 132 is mainly responsible for amplifying and forwarding the radio frequency signals of the uplink (UL) / downlink (DL) between the base station 110 and the user equipment 120 via a backhaul link (B-link) and an access link (A-link). The behavior of the NCR-Fwd 132 is controlled by the SCI from the base station 110. Among them, the SCI may include one or more of the following information: beam information, timing information, UL-DL TDD configuration information, ON-OFF information of the NCR-Fwd, and power control information of the NCR-Fwd.

[0092] In a scenario where a relay node is deployed, in order to improve the spatial directivity of the relay node's forwarding, the base station can perform beam indication to the relay node. As an implementation method, the base station can use SCI for beam indication.

[0093] See Figure 3 , taking the scenario with NCR deployment as an example, for the access link, especially in high-frequency bands (such as the FR2 band), the base station can perform beam indication via SCI to increase the spatial directivity of NCR forwarding. In addition, the base station's beam indication to the NCR is also beneficial for suppressing interference and increasing the reliability of signal transmission.

[0094] As mentioned above, in a scenario with NCR deployment, the ON-OFF information of the NCR-Fwd indicated by the base station via SCI can be used to control the forwarding behavior of the NCR-Fwd. In some embodiments, if the base station does not directly or indirectly indicate the NCR-Fwd to be "on", the NCR-Fwd always remains in the "off" state. The NCR-Fwd defaulting to the "off" state is beneficial for saving the power consumption of the NCR and also for reducing unnecessary interference.

[0095] In some embodiments, the base station performs beam indication to a relay node (e.g., NCR) to increase the spatial directivity of the relay node's forwarding or to indicate that the relay node "turns on". According to the latest progress of NR Rel-18 standardization, the access link supports periodic beam indication and aperiodic beam indication. Periodic beam indication supports configuring a number of forwarding resources, a periodic beam indication period, and a reference subcarrier spacing (SCS) through radio resource control (RRC) signaling. Each forwarding resource consists of a beam index and a time resource. Aperiodic beam indication indicates the beam index and the time resource through DCI. For the FR1 frequency band and the FR2 frequency band, the "turn on" state indication of the relay node is also completed through beam indication. In some embodiments, even if the relay node has only one beam, the beam indication sent by the base station to the relay node is used to indicate the "turn on" state of the relay node.

[0096] In some embodiments, the base station performs beam indication to a relay node (e.g., NCR) to indicate that the relay node "turns off". Although the relay node is in the "off" state by default and generally does not need to be specifically indicated to return from the "on" state to the "off" state, when the base station uses semi-static or semi-persistent transmission for the access link through periodic beam indication, due to certain special circumstances, such as avoiding high-priority burst services, etc., the relay node needs to temporarily return from the "on" state to the "off" state, which requires dynamic signaling (e.g., DCI) to indicate that the relay node returns to the "off" state. As an implementation method, many companies have proposed to indicate that the relay node is in the "off" state on certain time resources by indicating a specific beam index (e.g., "beam 0") and the time resource, in order to be consistent with the method of indicating that the relay node is in the "on" state.

[0097] It can be seen that in various cases, the base station needs to perform beam indication to the relay node. Exemplarily, the base station can use the following two methods to perform beam indication to the relay node.

[0098] Method 1: The base station can simultaneously indicate a combination of multiple beam indices and a time resource (TR) through dynamic signaling (e.g., DCI). Figure 4 Shows an example of simultaneously indicating a combination of multiple beam indices and a time resource. However, using Method 1 will cause the following two problems.

[0099] On the one hand, the 111th RAN1 meeting agreed that each time-domain resource consists of a starting slot (i.e., the slot offset within a period), a starting symbol (i.e., the symbol offset within a slot), and a duration (i.e., the number of symbols), as shown in Table 1. In this case, Method 1 will result in a large signaling overhead in the time-domain resource indication field, and due to the load limitation of dynamic signaling, the combination of beam indices and time-domain resources that can be indicated by dynamic signaling is limited.

[0100] Table 1

[0101] Time domain resource Time slot offset Symbol offset Duration TR 0 1 2 3 TR 1 1 5 2 TR 2 2 1 13 ......

[0102] On the other hand, when multiple time-domain resources use the same beam, as Figure 5 shown, the same beam index (such as "beam 1") corresponding to multiple time-domain resources needs to occupy multiple fields in a signaling, resulting in low signaling utilization efficiency.

[0103] Method 2: The base station can configure multiple time-domain resource sets (TRS) through high-layer signaling (e.g., RRC signaling), and the configured time-domain resource sets are shown in Table 2. Then, the base station can indicate the combination between multiple beam indices and the time-domain resource sets through dynamic signaling (e.g., DCI), as Figure 6 shown. Using Method 2 can effectively indicate the beam indices on multiple time-domain resource sets, save signaling overhead, and reduce the processing delay caused by multiple signalings.

[0104] Table 2

[0105] Time domain resource set ID Time domain resource TRS 0 TR0, TR1, TR2 TRS1 TR2, TR3 TRS2 TR0, TR1, TR3 ......

[0106] However, when using Method 2, due to the limitation of signaling load, it is impossible to traverse all time-domain resource sets, and some time-domain resources in multiple time-domain resource sets overlap, resulting in multiple beam indices corresponding to these time-domain resources, causing beam indication conflicts, confusing the operations of relay nodes, or increasing the power consumption of relay nodes, or increasing signaling overhead, or increasing transmission delay, or reducing the accuracy of beam indication, or reducing the system transmission quality. The following is combined with Figure 7 to give an example.

[0107] Such as Figure 7As shown, beam 0 corresponds to the "off" state. When the dynamic signaling includes beam indication combination 1 {beam 0, TRS 0} and beam indication combination 2 {beam 1, TRS1}, TRS 0 includes time-domain resource TR2, and TRS1 also includes TR2.

[0252] For ease of understanding, the following describes how to determine the first state of the second module on the first time-domain resource in conjunction with specific examples, so that the operations of the first node on the first time-domain resource will not be confused. In the following examples, NCR corresponds to the first node mentioned above, the beam indication combination corresponds to the first information mentioned above, the beam index corresponds to the beam information mentioned above, and gNB corresponds to the second node mentioned above. It should be noted that the following examples are only for helping those skilled in the art to understand the embodiments of the present application, rather than limiting the embodiments of the present application to the specific values or specific scenarios shown. Those skilled in the art can obviously make various equivalent modifications or changes according to the specific examples given, and such modifications or changes also fall within the scope of the embodiments of the present application.

[0253] It should be noted that in the following examples, solid lines indicate the operations that the second module needs to perform on the first time-domain resource, and dashed lines indicate the operations that the second module does not need to perform on the first time-domain resource.

[0254] Example 1: At least one of the at least two beam information is the first beam information

[0255] When at least two beam indication combinations in the same signaling or different signalings conflict on the first time-domain resource, if one of the beam indices includes beam 0 (i.e., used to indicate that the second module is in the off state), then NCR determines that the second module is in the off state on the first time-domain resource (i.e., performs an off operation on the first time-domain resource) to avoid causing unnecessary interference.

[0256] As Figure 9 shown, beam indication combination 1 and beam indication combination 2 conflict on TR2, where the beam index corresponding to beam indication combination 1 is beam 0. Therefore, NCR can determine that the second module is in the off state on TR2.

[0257] In Figure 9 the example, beam 0 is represented by a solid line, used to indicate that the second module is in the off state on the first time-domain resource; beam1 is represented by a dashed line, used to indicate that the second module does not perform transmission using beam 1 on the first time-domain resource.

[0258] Example 2: The second beam information is used to determine the first type of beam, and the second beam information is randomly selected

[0259] In Example 2, NCR only supports single-beam transmission.

[0260] When at least two beam indication combinations in the same signaling or different signalings conflict on the first time-domain resource, if the two beam indication combinations indicate different beam indices on the first time-domain resource, on the first time-domain resource, NCR randomly selects one beam index from the indicated beam indices and performs transmission according to the beam corresponding to the selected beam index.

[0261] As Figure 10 shown, beam indication combination 1 and beam indication combination 2 conflict on TR2. Beam indication combination 1 indicates to perform transmission using beam 1 on TR2, and beam indication combination 2 indicates to perform transmission using beam 2 on TR2. NCR randomly selects beam 2 as the first type of beam and performs transmission on TR2 according to the beam corresponding to beam 2.

[0262] In Figure 10 the example, beam 2 is represented by a solid line, indicating that the second module performs transmission using beam 2 on the first time-domain resource; beam 1 is represented by a dashed line, indicating that the second module does not perform transmission using beam 1 on the first time-domain resource.

[0263] Example 3: The second beam information is used to determine the first type of beam, and the second beam information is selected based on the position of the beam information Figure 11 In Example 3, NCR only supports single-beam transmission.

[0264] When at least two beam indication combinations from the same signaling or different signalings conflict on the first time-domain resource, if the two beam indication combinations indicate different beam indexes on the first time-domain resource, on the first time-domain resource, NCR determines a beam index according to the positions of the beam indexes corresponding to the at least two beam indication combinations in multiple domains of the first information, and performs transmission according to the beam corresponding to the selected beam index. For example, on the first time-domain resource, NCR can select the beam index with a higher position in multiple domains of the first information among the indicated at least two beam indication combinations as the first type of beam.

[0265] As Figure 12 shown, beam indication combination 1 and beam indication combination 2 conflict on TR2. Beam indication combination 1 indicates to perform transmission using beam 1 on TR2, and beam indication combination 2 indicates to perform transmission using beam 2 on TR2. NCR selects the beam index (beam 1) with a higher position in multiple domains of the first information among the indicated beam indication combination 1 and beam indication combination 2 as the first type of beam and performs transmission on TR2 according to the beam corresponding to beam 1, where the positions of beam indication combination 1 and beam indication combination 2 in multiple domains of the first information can be referred to Figure 11 . As an embodiment, gNB can arrange the preferred (recommended) beam indication combinations in the positions with higher precedence in multiple domains of the first information.

[0266] In Example 4: All the beam information among the at least two beam information is used to determine the first type of beamIn the example, beam 1 is represented by a solid line, which is used to indicate that the second module performs transmission using beam 1 on the first time-domain resource; beam 2 is represented by a dashed line, which is used to indicate that the second module does not perform transmission using beam 2 on the first time-domain resource.

[0267] Figure 13

[0268] In Example 4, the NCR includes multiple radio frequency chains and can support multi-beam transmission.

[0269] When at least two beam indication combinations from the same signaling or different signalings conflict on the first time-domain resource, if the two beam indication combinations indicate different beam indices on the first time-domain resource, on the first time-domain resource, the NCR can take the union of the multiple beam indices indicated by the at least two beam indication combinations, and perform multi-beam transmission according to the beams corresponding to all the selected beam indices. For example, perform multi-beam transmission according to the beams corresponding to all the selected beam indices on the A-link.

[0270] As Figure 13 shown, beam indication combination 1 and beam indication combination 2 conflict on TR2. Beam indication combination 1 indicates performing transmission using beam 1 on TR2, and beam indication combination 2 indicates performing transmission using beam 2 on TR2. The NCR selects to perform multi-beam transmission using the beams corresponding to beam 1 and beam 2 on TR2.

[0271] In Figures 8 to 13 the example, both beam 1 and beam 2 are represented by solid lines, which are used to indicate that the second module performs multi-beam transmission using beam 1 and beam 2 on the first time-domain resource.

[0320] Figure 18 is a schematic diagram of the hardware module of the communication device provided by the embodiment of the present application. Specifically,​ A block diagram showing a first communication device 450 and a second communication device 410 communicating with each other in an access network is shown.

[0321] The first communication device 450 includes a controller / processor 459, a memory 460, a data source 467, a transmit processor 468, a receive processor 456, a multi-antenna transmit processor 457, a multi-antenna receive processor 458, a transmitter / receiver 454, and an antenna 452.

[0322] The second communication device 410 includes a controller / processor 475, a memory 476, a data source 477, a receive processor 470, a transmit processor 416, a multi-antenna receive processor 472, a multi-antenna transmit processor 471, a transmitter / receiver 418, and an antenna 420.

[0323] In the transmission from the second communication device 410 to the first communication device 450, at the second communication device 410, an upper-layer data packet from the core network or an upper-layer data packet from the data source 477 is provided to the controller / processor 475. The core network and the data source 477 represent all protocol layers above the L2 layer. The controller / processor 475 implements the functionality of the L2 layer. In the transmission from the second communication device 410 to the first communication device 450, the controller / processor 475 provides header compression, encryption, packet segmentation and reordering, multiplexing between logical and transport channels, and radio resource allocation to the first communication device 450 based on various priority metrics. The controller / processor 475 is also responsible for retransmission of lost packets and signaling to the first communication device 450. The transmit processor 416 and the multi-antenna transmit processor 471 implement various signal processing functions for the Ll layer (i.e., the physical layer). The transmit processor 416 implements encoding and interleaving to facilitate forward error correction at the second communication device 410, and mapping of signal constellations based on various modulation schemes (e.g., binary phase shift keying, quadrature phase shift keying, M-phase shift keying, M-quadrature amplitude modulation). The multi-antenna transmit processor 471 performs digital spatial precoding on the encoded and modulated symbols, including codebook-based precoding and non-codebook-based precoding, and beamforming processing, to generate one or more spatial streams. The transmit processor 416 then maps each spatial stream to subcarriers, multiplexes with reference signals (e.g., pilots) in the time domain and / or frequency domain, and then uses the inverse fast Fourier transform to generate a physical channel carrying a time-domain multi-carrier symbol stream. Subsequently, the multi-antenna transmit processor 471 performs a transmit analog precoding / beamforming operation on the time-domain multi-carrier symbol stream. Each transmitter 418 converts the baseband multi-carrier symbol stream provided by the multi-antenna transmit processor 471 into a radio frequency stream, and then provides it to different antennas 420.

[0324] In the transmission from the second communication device 410 to the first communication device 450, at the first communication device 450, each receiver 454 receives signals via its respective antenna 452. Each receiver 454 recovers the information modulated onto the radio frequency carrier and converts the radio frequency stream into a baseband multi-carrier symbol stream for providing to the receive processor 456. The receive processor 456 and the multi-antenna receive processor 458 perform various signal processing functions of the L1 layer. The multi-antenna receive processor 458 performs receive analog precoding / beamforming operations on the baseband multi-carrier symbol stream from the receivers 454. The receive processor 456 uses the fast Fourier transform to convert the baseband multi-carrier symbol stream after the receive analog precoding / beamforming operations from the time domain to the frequency domain. In the frequency domain, the physical layer data signal and the reference signal are demultiplexed by the receive processor 456, where the reference signal will be used for channel estimation, and the data signal recovers any spatial streams destined for the first communication device 450 after multi-antenna detection in the multi-antenna receive processor 458. The symbols on each spatial stream are demodulated and recovered in the receive processor 456, and soft decisions are generated. Subsequently, the receive processor 456 decodes and de-interleaves the soft decisions to recover the upper layer data and control signals transmitted by the second communication device 410 on the physical channel. Subsequently, the upper layer data and control signals are provided to the controller / processor 459. The controller / processor 459 performs the functions of the L2 layer. The controller / processor 459 may be associated with a memory 460 that stores program code and data. The memory 460 may be referred to as a computer-readable medium. In the transmission from the second communication device 410 to the first communication device 450, the controller / processor 459 provides demultiplexing between transport and logical channels, packet reassembly, decryption, header decompression, control signal processing to recover the upper layer data packets from the second communication device 410. Subsequently, the upper layer data packets are provided to all protocol layers above the L2 layer. Various control signals may also be provided to the L3 for L3 processing.

[0325] In the transmission from the first communication device 450 to the second communication device 410, at the first communication device 450, an upper layer data packet is provided to the controller / processor 459 using the data source 467. The data source 467 represents all protocol layers above the L2 layer. Similar to the transmit function at the second communication device 410 described in the transmission from the second communication device 410 to the first communication device 450, the controller / processor 459 implements header compression, encryption, packet segmentation and reordering, and multiplexing between logical and transport channels, and implements L2 layer functions for the user plane and the control plane. The controller / processor 459 is also responsible for retransmission of lost packets and signaling to the second communication device 410. The transmit processor 468 performs modulation mapping and channel coding processing. The multi-antenna transmit processor 457 performs digital multi-antenna spatial precoding, including codebook-based precoding and non-codebook-based precoding, and beamforming processing. Subsequently, the transmit processor 468 modulates the generated spatial streams into a multi-carrier / single-carrier symbol stream, and after passing through the analog precoding / beamforming operation in the multi-antenna transmit processor 457, it is provided to different antennas 452 via the transmitter 454. Each transmitter 454 first converts the baseband symbol stream provided by the multi-antenna transmit processor 457 into a radio frequency symbol stream and then provides it to the antenna 452.

[0326] In the transmission from the first communication device 450 to the second communication device 410, the functions at the second communication device 410 are similar to the receive function at the first communication device 450 described in the transmission from the second communication device 410 to the first communication device 450. Each receiver 418 receives a radio frequency signal through its corresponding antenna 420, converts the received radio frequency signal into a baseband signal, and provides the baseband signal to the multi-antenna receive processor 472 and the receive processor 470. The receive processor 470 and the multi-antenna receive processor 472 jointly implement the Ll layer functions. The controller / processor 475 implements the L2 layer functions. The controller / processor 475 may be associated with a memory 476 that stores program code and data. The memory 476 may be referred to as a computer-readable medium. In the transmission from the first communication device 450 to the second communication device 410, the controller / processor 475 provides demultiplexing between transport and logical channels, packet reassembly, decryption, header decompression, and control signal processing to recover the upper layer data packet from the first communication device 450. The upper layer data packet from the controller / processor 475 may be provided to the core network or all protocol layers above the L2 layer, and various control signals may also be provided to the core network or L3 for L3 processing.
