Description

Technical Field

[0001] The present application relates to the field of communication technology, and more specifically, to a method and device for a node used for wireless communication. Background Art

[0002] In order to improve the coverage of the network and support the rapidly growing number of users, some new network nodes are gradually being proposed. Such new network nodes can increase the flexibility of network deployment and thus have attracted 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 base stations. The relay node can be, for example, a network-controlled repeater (NCR).

[0003] In a scenario where a relay node is deployed, in order to improve the spatial directivity of the relay node forwarding, the base station can provide beam indication to the relay node. When the base station provides beam indication to the relay node by indicating the combination of beam information and time domain resource set, due to the load limit of the indication signaling, some time domain resources may correspond to multiple different beam information, resulting in beam indication conflicts, confusion in relay node operation, or increased power consumption of the relay node, or increased signaling overhead, or increased transmission delay, or reduced accuracy of beam indication, or reduced system transmission quality.

[0085] It should be understood that all or part of the functions of the communication device in the present application may also be implemented by software functions running on hardware, or by virtualization functions instantiated on a platform (eg, a cloud platform).

[0086] New network nodes in communication systems

[0087] With the trend of network densification and millimeter wave (mmW) communication applications, some new network nodes are gradually being proposed to improve network coverage and support the rapidly growing number of users. These new network nodes can increase the flexibility of network deployment and thus have received increasing attention.

[0088] For example, NR Rel-16 (release-16) introduced the integrated access and backhaul (IAB) node. The IAB node was further enhanced in NR Rel-17 (release-17). The biggest feature of the IAB node is that it does not require a wired backhaul link between network nodes.

[0089] For example, wireless repeaters, which are widely used in 2G, 3G and 4G systems, are also a relatively new type of network node besides base stations. Wireless repeaters can also be called radio frequency repeaters (RFrepeaters) or relays. Traditional wireless repeaters simply amplify and forward received signals. 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 the performance is poor. Compared with traditional wireless repeaters, some communication systems have introduced NCR. NCR adds the ability to receive and process side control information (SCI) from network equipment. Based on SCI, NCR can efficiently perform signal amplification and forwarding functions, reduce unnecessary noise amplification, so that NCR reception and transmission have better spatial directivity and simplify network integration. NR Rel-18 (release-18) version carried out the study item (SI) of NCR. In September 2022, 3GPP passed RP-222673 and started the "NR NCR" work item (WI) in NR Rel-18, thus officially starting the standardization work of NCR in the NR system.

[0090] According to NCR's research report (3GPP TR38.867), Figure 2As shown, NCR 130 mainly includes two functional modules: NCR-mobile termination (NCR-MT) 131 and NCR-forwarding (NCR-Fwd) 132. NCR-MT 131 can be responsible for exchanging SCI with base station 110 through control link (C-link). NCR-Fwd (NCR-forwarding) 132 is mainly responsible for amplifying and forwarding the uplink (UL) / downlink (DL) radio frequency signals between base station 110 and user equipment 120 through backhaul link (B-link) and access link (A-link). The behavior of NCR-Fwd 132 is controlled by SCI from base station 110. Among them, SCI may include one or more of the following information: beam information, timing information, uplink and downlink time division duplex configuration (UL-DL TDD configuration) information, NCR-Fwd switch information (ON-OFF information), and NCR-Fwd power control information (power control information).

[0091] In a scenario where a relay node is deployed, in order to improve the spatial directivity of forwarding by the relay node, the base station can provide beam indication to the relay node. As an implementation method, the base station can use SCI for beam indication.

[0092] See also Figure 3 Taking the scenario where NCR is deployed as an example, for access links, especially high-frequency bands (such as FR2 bands), the base station can perform beam indication through SCI to increase the spatial directivity of NCR forwarding. In addition, the base station's beam indication to NCR is also conducive to suppressing interference and increasing the reliability of signal transmission.

[0093] As described above, in a scenario where NCR is deployed, the switch information of NCR-Fwd indicated by the base station through SCI can be used to control the forwarding behavior of NCR-Fwd. In some embodiments, if the base station does not directly or indirectly indicate that NCR-Fwd is "on", NCR-Fwd always remains in the "off" state. Keeping NCR-Fwd in the "off" state by default is beneficial to saving the power consumption of NCR and also beneficial to reducing unnecessary interference.

[0094] In some embodiments, the base station performs beam indication to the relay node (e.g., NCR) in order to increase the spatial directionality of the relay node forwarding or to indicate that the relay node is "on". According to the latest progress in NR Rel-18 standardization, the access link supports periodic beam indication and aperiodic beam indication. Periodic beam indication supports the configuration of a number of forwarding resources, periodic beam indication period and reference subcarrier spacing (SCS) through radio resource control (RRC) signaling, where each forwarding resource consists of a beam index and a time resource. Aperiodic beam indication indicates the beam index and time resource through DCI. For FR1 and FR2 bands, the "on" status 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 "on" state of the relay node.

[0095] In some embodiments, the base station performs beam indication to a relay node (e.g., NCR) in order to instruct the relay node to be "off". Although the relay node is in the "off" state by default, it is generally not necessary to specifically instruct the relay node to return from the "on" state to the "off" state. However, when the base station indicates through periodic beams that the access link adopts semi-static or semi-persistent transmission, due to certain special circumstances, such as avoiding high-priority burst services, the relay node needs to temporarily return from the "on" state to the "off" state, which requires dynamic signaling (such as DCI) to instruct the relay node to return to the "off" state. As an implementation method, many companies have proposed indicating that the relay node is in the "off" state on certain time domain resources by indicating a specific beam index (such as "beam 0") and time domain resources, so as to be consistent with the method of indicating that the relay node is in the "on" state.

[0096] It can be seen that in many cases, the base station needs to provide beam indication to the relay node. Exemplarily, the base station can provide beam indication to the relay node in the following two ways.

[0097] Method 1: The base station can simultaneously indicate a combination of multiple beam indices and time domain resources (TR) through dynamic signaling (e.g., DCI). Figure 4 An example of indicating a combination of multiple beam indices and time domain resources at the same time is shown. However, adopting the first approach will lead to the following two problems.

[0098] On the one hand, the RAN1#111 meeting agreed that each time domain resource consists of a starting slot (i.e., a slot offset within a cycle), a starting symbol (i.e., a symbol offset in the time 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 limit of dynamic signaling, the combination of beam index and time domain resource that can be indicated by dynamic signaling is limited.

[0099] Table 1

[0100] Time Domain Resources Slot offset Symbol offset Duration TR 0 1 2 3 TR 1 1 5 2 TR 2 2 1 13 ......

[0101] On the other hand, when multiple time domain resources use the same beam, such as Figure 5 As shown, the same beam index (such as "beam 1") corresponding to multiple time domain resources needs to occupy multiple fields in one signaling, resulting in low signaling utilization efficiency.

[0102] Method 2: The base station can configure multiple time resource sets (TRS) through high-level signaling (e.g., RRC signaling), and the configured time resource sets are shown in Table 2. Then, the base station can indicate the combination of multiple beam indices and time resource sets through dynamic signaling (e.g., DCI), such as Figure 6 The second method can effectively indicate beam indexes on multiple time domain resource sets, save signaling overhead, and reduce processing delays caused by multiple signaling.

[0103] Table 2

[0104] Time domain resource set ID Time Domain Resources TRS 0 TR0, TR1, TR2 TRS 1 TR2, TR3 TRS 2 TR0, TR1, TR3 ......

[0105] However, when using the second method, due to the limitation of signaling load, all time domain resource sets cannot be traversed, and some time domain resources in multiple time domain resource sets overlap, resulting in multiple beam indexes corresponding to these time domain resources, causing beam indication conflicts, causing confusion in relay node operations, 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 system transmission quality. Figure 7 Give an example.

[0106] like 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, TRS 1}, TRS 0 includes time domain resource TR2, and TRS 1 also includes TR2. As a result, on the time domain resource TR2, the relay node does not know whether to perform the "off" operation or use beam 1 to perform transmission.

[0107] In response to the above problems, the node with relay function provided in the embodiment of the present application can determine that the second module of the first node is in an off state according to at least one of at least two beam information conflicting on the first time domain resource, or determine the first type of beam used to send or receive wireless signals, thereby achieving one or more of the following purposes: solving the problem of beam indication conflict, saving power consumption of relay nodes, saving signaling overhead, reducing transmission delay, improving the accuracy of beam indication, and improving system transmission quality.

[0108] The method and apparatus provided by the present application are illustrated below by multiple embodiments or examples. It should be understood that, in the absence of conflict, the embodiments in the first node of the present application and the features in the embodiments can be applied to the second node, and vice versa. In the absence of conflict, the embodiments of the present application and the features in the embodiments can be arbitrarily combined with each other.

[0251] 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 a specific example so that the operation of the first node on the first time domain resource will not be confused. In the following example, 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 the gNB corresponds to the second node mentioned above. It should be noted that the following examples are only intended to help those skilled in the art understand the embodiments of the present application, and are not intended to limit the embodiments of the present application to the specific numerical values ​​or specific scenarios illustrated. Those skilled in the art can obviously make various equivalent modifications or changes based on the specific examples given, and such modifications or changes also fall within the scope of the embodiments of the present application.

[0252] It should be noted that, in the following examples, the solid line represents the operation that the second module needs to perform on the first time domain resource, and the dotted line represents the operation that the second module does not need to perform on the first time domain resource.

[0253] Example 1: At least one of the at least two beam information is the first beam information

[0254] When at least two beam indication combinations from the same signaling or different signaling conflict on the first time domain resource, if one of the beam indexes includes beam 0 (i.e., used to indicate that the second module is in the off state), the NCR determines that the second module is in the off state on the first time domain resource (i.e., performs a off operation on the first time domain resource) to avoid causing unnecessary interference.

[0255] like Fig. 9 As shown, beam indication combination 1 and beam indication combination 2 conflict on TR2, wherein 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.

[0256] exist Fig. 9 In the example of FIG. 1 , beam 0 is represented by a solid line, indicating that the second module is in a closed state on the first time domain resource; beam 1 is represented by a dotted line, indicating that the second module does not use beam 1 to perform transmission on the first time domain resource.

[0257] Example 2: The second beam information is used to determine the first type of beam, and the second beam information is randomly selected

[0258] In Example 2, NCR only supports single-beam transmission.

[0259] When at least two beam indication combinations from the same signaling or different signaling conflict on the first time domain resource, if the two beam indication combinations respectively indicate different beam indexes on the first time domain resource, on the first time domain resource, the NCR randomly selects a beam index from the indicated beam indexes and performs transmission according to the beam corresponding to the selected beam index.

[0260] like Fig.10 As shown, beam indication combination 1 and beam indication combination 2 conflict on TR2. Beam indication combination 1 indicates on TR2 that beam 1 is used to perform transmission, and beam indication combination 2 indicates on TR2 that beam 2 is used to perform transmission. NCR randomly selects beam 2 as the first type of beam and performs transmission on TR2 according to the beam corresponding to beam 2.

[0261] exist Fig.10 In the example, beam 2 is represented by a solid line, indicating that the second module uses beam 2 to perform transmission on the first time domain resource; beam 1 is represented by a dotted line, indicating that the second module does not use beam 1 to perform transmission on the first time domain resource.

[0262] Example 3: The second beam information is used to determine the first type of beam, wherein the second beam information is based on the beam information The location selected In Example 3, NCR only supports single-beam transmission.

[0263] When at least two beam indication combinations from the same signaling or different signaling 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, the NCR determines a beam index according to the positions of the beam indexes corresponding to the at least two beam indication combinations in the multiple fields 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, the NCR may select a beam index that is located at the front in the multiple fields of the first information from among the at least two beam indication combinations indicated as a first type of beam.

[0264] like Fig.11 As shown, beam indication combination 1 and beam indication combination 2 conflict on TR2, beam indication combination 1 indicates on TR2 that beam 1 is used for transmission, and beam indication combination 2 indicates on TR2 that beam 2 is used for transmission. NCR selects a beam index (beam 1) that is at the front position in multiple fields of the first information as the first type of beam in the indicated beam indication combination 1 and beam indication combination 2, and performs transmission on TR2 according to the beam corresponding to beam 1. The positions of beam indication combination 1 and beam indication combination 2 in multiple fields of the first information can be found in Fig.12 As an embodiment, the gNB may arrange the preferred (recommended) beam indication combination at a front position in the multiple fields of the first information.

[0265] exist Fig.11In the example, beam 1 is represented by a solid line, indicating that the second module uses beam 1 to perform transmission on the first time domain resource; beam 2 is represented by a dotted line, indicating that the second module does not use beam 2 to perform transmission on the first time domain resource.

[0266] Example 4: All beam information in at least two beam information is used to determine the first type of beam

[0267] In Example 4, the NCR includes multiple RF chains and can support multi-beam transmission.

[0268] When at least two beam indication combinations from the same signaling or different signaling conflict on the first time domain resource, if the two beam indication combinations respectively indicate different beam indexes on the first time domain resource, on the first time domain resource, the NCR can take the union of the multiple beam indexes 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 on the A-link according to the beams corresponding to all the selected beam indices.

[0269] like Fig.13 As shown, beam indication combination 1 and beam indication combination 2 conflict on TR2. Beam indication combination 1 indicates on TR2 that beam 1 is used to perform transmission, and beam indication combination 2 indicates on TR2 that beam 2 is used to perform transmission. NCR chooses to use the beams corresponding to beam 1 and beam 2 to perform multi-beam transmission on TR2.

[0270] exist Fig.13 In the example, beam 1 and beam 2 are both represented by solid lines, indicating that the second module performs multi-beam transmission using beam 1 and beam 2 on the first time domain resource.

[0319] Fig.18 A schematic diagram of the hardware modules of a communication device provided in an embodiment of the present application. Specifically, Fig.18 A block diagram is shown of a first communication device 450 and a second communication device 410 communicating with each other in an access network.

[0320] 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.

[0321] 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.

[0322] In the transmission from the second communication device 410 to the first communication device 450, at the second communication device 410, the upper layer data packets from the core network or the upper layer data packets from the data source 477 are provided to the controller / processor 475. The core network and the data source 477 represent all the 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 the 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 L1 layer (i.e., the physical layer). The transmit processor 416 implements coding and interleaving to facilitate forward error correction at the second communication device 410, as well as 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, including codebook-based precoding and non-codebook-based precoding, and beamforming processing on the coded and modulated symbols to generate one or more spatial streams. The transmit processor 416 then maps each spatial stream to a subcarrier, multiplexes it with a reference signal (e.g., a pilot) in the time domain and / or frequency domain, and then uses an inverse fast Fourier transform to generate a physical channel carrying a time domain multi-carrier symbol stream. The multi-antenna transmit processor 471 then 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, which is then provided to different antennas 420.

[0323] 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 a signal through its corresponding 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 and provides it to the receiving processor 456. The receiving processor 456 and the multi-antenna receiving processor 458 implement various signal processing functions of the L1 layer. The multi-antenna receiving processor 458 performs a receiving analog precoding / beamforming operation on the baseband multi-carrier symbol stream from the receiver 454. The receiving processor 456 uses a fast Fourier transform to convert the baseband multi-carrier symbol stream after the receiving analog precoding / beamforming operation 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 receiving processor 456, wherein the reference signal will be used for channel estimation, and the data signal is recovered after multi-antenna detection in the multi-antenna receiving processor 458 to any spatial stream with the first communication device 450 as the destination. The symbols on each spatial stream are demodulated and recovered in the receiving processor 456, and soft decisions are generated. The receiving processor 456 then decodes and deinterleaves the soft decisions to recover the upper layer data and control signals transmitted by the second communication device 410 on the physical channel. The upper layer data and control signals are then provided to the controller / processor 459. The controller / processor 459 implements the functions of the L2 layer. The controller / processor 459 may be associated with a memory 460 that stores program codes 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 multiplexing 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. The upper layer data packets are then provided to all protocol layers above the L2 layer. Various control signals may also be provided to the L3 for L3 processing.

[0324] In the transmission from the first communication device 450 to the second communication device 410, at the first communication device 450, the upper layer data packets are provided to the controller / processor 459 using the data source 467. The data source 467 represents all the protocol layers above the L2 layer. Similar to the transmission 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 user plane and control plane. The controller / processor 459 is also responsible for the retransmission of lost packets and signaling to the second communication device 410. The transmit processor 468 performs modulation mapping and channel coding processing, and the multi-antenna transmit processor 457 performs digital multi-antenna spatial precoding, including codebook-based precoding and non-codebook-based precoding, and beamforming processing. Then, the transmit processor 468 modulates the generated spatial stream into a multi-carrier / single-carrier symbol stream, which is then provided to different antennas 452 via the transmitter 454 after analog precoding / beamforming operations in the multi-antenna transmit processor 457. 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.

[0325] In the transmission from the first communication device 450 to the second communication device 410, the function at the second communication device 410 is similar to the reception 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 reception processor 472 and the reception processor 470. The reception processor 470 and the multi-antenna reception processor 472 jointly implement the functions of the L1 layer. The controller / processor 475 implements the L2 layer functions. The controller / processor 475 can be associated with a memory 476 storing program codes and data. The memory 476 can 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 multiplexing between transport and logical channels, packet reassembly, decryption, header decompression, control signal processing to recover the upper layer data packets from the first communication device 450. The upper layer data packets 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.
