Description

[Technical Field]

[0001] FIELD OF THE INVENTION This application relates to the field of communications, and more particularly to a method and apparatus for a node for wireless communications. [Background technology]

[0002] In order to improve the coverage capability of a network and support the rapidly increasing number of users, several novel network nodes have been proposed. These novel network nodes can increase the flexibility of network configuration, and thus have attracted more and more attention. For example, some communication systems introduce relay nodes that can amplify and forward radio signals between user equipment (UE) and base stations. The relay nodes may be, for example, network-controlled repeaters (NCRs).

[0003] In a scenario where a relay node is configured, the base station can provide beam instructions to the relay node to improve the spatial directionality of relay node transmission. When the base station provides beam instructions to the relay node by combining beam instruction information and a time domain resource set, due to load restrictions on instruction signaling, multiple different beam information may be associated with some time domain resources, causing beam instructions to collide, disrupting relay node operation, increasing power consumption of the relay node, increasing signaling overhead, increasing transmission delay, reducing the accuracy of beam instructions, or reducing system transmission quality.

DETAILED DESCRIPTION OF THE INVENTION

The base station may support networks of the same or different access technologies. The embodiments of the present application do not limit the specific technology adopted by the network equipment or the specific form of the equipment.

[0065] The base station may be fixed or mobile. For example, a helicopter or a drone may be configured as a mobile base station, and one or more cells may move depending on the location of the mobile base station. In another example, a helicopter or a drone may be configured as a device for communicating with another base station.

[0067] The network equipment and the user equipment may be located indoors or outdoors, on land, including handheld or vehicle-mounted, on water, or in the air, such as on an airplane, a balloon, or a satellite. The embodiments of the present application do not limit the scenario in which the network equipment and the user equipment are located.

[0068] It should be understood that all or part of the functionality of the communication device in this application may be realized by software functions executed on hardware, or by virtualization functions instantiated on a platform (e.g., a cloud platform). Novel network node in a communication system

[0069] With the trend of network densification and the application of millimeter wave (mmW) communication, some novel network nodes have been proposed to improve the network coverage capability and support the rapidly increasing number of users. Such novel network nodes can increase the flexibility of network configuration, and thus have attracted more and more attention.

[0070] For example, the NR Rel-16 (release-16) version introduces an integrated access and backhaul (IAB) node, which will be further enhanced in the NR Rel-17 (release-17) version. The most notable feature of the IAB node is that it does not require wired backhaul links between network nodes.

[0071] Wireless repeaters, widely applied in 2G, 3G, and 4G systems, also belong to a relatively new category of network nodes other than base stations. Wireless repeaters may also be called radio frequency repeaters (RF repeaters) or relays. Conventional wireless repeaters simply amplify and forward received signals. While these types of wireless repeaters are simple in function and relatively cost-effective, they lack the flexibility to adjust based on the actual conditions of the communication system, resulting in poor performance. Compared to conventional wireless repeaters, some communication systems employ non-repetitive control (NCR) technology. NCR improves the ability to receive and process side control information (SCI) from network devices. Based on SCI, NCR can efficiently perform signal amplification and forwarding functions, thereby reducing unnecessary noise amplification and improving spatial directivity of NCR transmission and reception, simplifying network integration. The NR Rel-18 (release-18) version will include a study item (SI) for NCR. In September 2022, 3GPP will approve RP-222673 and launch the "NRNCR" work item (WI) in NRRel-18, thereby formalizing standardization work on NCR in NR systems.

[0072] According to the NCR research report (3GPP TR38.867), as shown in FIG. 2, the NCR 130 mainly includes two functional modules: a network controlled repeater-mobile termination (NCR-MT) 131 and a network controlled repeater-forwarding (NCR-Fwd) 132. The NCR-MT 131 can interact with the base station 110 via a control link (C-link). The NCR-Fwd (NCR-forwarding) 132 mainly amplifies and forwards uplink (UL) / downlink (DL) radio frequency signals between the base station 110 and the user equipment 120 via a backhaul link (B-link) and an access link (A-link). The operation of the NCR-Fwd 132 is controlled by the SCI from the base station 110. The SCI may include one or more of beam information, timing information, uplink-downlink time division duplex configuration (UL-DL TDD configuration) information, NCR-Fwd on / off information, and NCR-Fwd power control information.

[0073] In a scenario where relay nodes are deployed, the base station can provide beam direction to the relay nodes to improve spatial directionality of relay node transmissions. In one implementation, the base station can provide beam direction using the SCI.

[0074] Referring to Figure 3, taking a scenario where NCR is deployed as an example, a base station can perform beam direction by SCI for an access link, especially for a high frequency band (e.g., FR2 frequency band), to increase the spatial directivity of NCR transmission. In addition, the base station's beam direction for NCR is also advantageous in suppressing interference and increasing the reliability of signal transmission.

[0075] As described above, in a scenario where NCR is deployed, the NCR-Fwd on / off information instructed by the base station via the SCI can be used to control the forwarding operation of NCR-Fwd. In some embodiments, unless the base station directly or indirectly instructs NCR-Fwd "on," NCR-Fwd is always maintained in the "off" state. Maintaining NCR-Fwd in the "off" state by default is advantageous for saving power overhead of NCR and for reducing unnecessary interference.

[0076] In some embodiments, a base station provides beam direction to a relay node (e.g., NCR) to increase the spatial directivity of relay node transmission or to indicate the relay node's "on" status. According to recent developments in the NR Rel-18 standardization, the access link supports periodic and aperiodic beam direction. Periodic beam direction supports configuring multiple forwarding resources, periodic beam direction periods, and reference subcarrier spacing (SCS) through radio resource control (RRC) signaling, with each forwarding resource consisting of a beam index and a time resource. Aperiodic beam direction indicates the beam index and time resource through DCI. For the FR1 and FR2 frequency bands, indicating the relay node's "on" status is also achieved through beam direction. In some embodiments, a relay node has only one beam, and the beam direction transmitted by the base station to the relay node is also used to indicate the relay node's "on" status.

[0077] In some embodiments, a base station issues beam instructions to a relay node (e.g., NCR) to instruct the relay node to turn "off." A relay node is in the "off" state by default, and generally, there is no need to specifically instruct the relay node to return to the "off" state from the "on" state. However, when the base station is instructed by periodic beam instructions and the access link uses semi-static or semi-persistent transmission, due to some special circumstances, such as avoiding high-priority burst traffic, the relay node may need to temporarily return from the "on" state to the "off" state, and dynamic signaling (e.g., DCI) may be required to instruct the relay node to return to the "off" state. In one implementation, many companies have proposed instructing a relay node to be in the "off" state for some time-domain resources by instructing a specific beam index (e.g., "beam0") and time-domain resource, consistent with the scheme for instructing the relay node to be in the "on" state.

[0078] As can be seen from the above, in many situations, the base station needs to provide beam direction to the relay node. For example, the base station can provide beam direction to the relay node using the following two methods:

[0079] Scheme 1: The base station can simultaneously indicate multiple combinations of beam indexes and time domain resources (TRs) through dynamic signaling (e.g., DCI). Figure 4 shows an example of simultaneously indicating multiple combinations of beam indexes and time domain resources. However, using scheme 1 causes the following two problems.

[0080] On the other hand, the RAN1#111 meeting agreed that each time domain resource consists of a starting slot (i.e., slot offset within one period), a starting symbol (i.e., symbol offset within a slot), and a duration (i.e., number of symbols), as shown in Table 1. In this case, for Scheme 1, the signaling overhead in the time domain resource indication domain is relatively large, and due to the load constraints of dynamic signaling, the beam index and time domain that can be indicated by dynamic signaling are limited.

[0081] [Table 1]

[0082] On the other hand, when multiple time-domain resources use the same beam, as shown in Figure 5, the same beam index (e.g., "beam1") corresponding to multiple time-domain resources needs to occupy multiple domains in one signaling, resulting in low signaling utilization efficiency.

[0083] Scheme 2: The base station can configure multiple types of time domain resource sets (TRS) through higher layer signaling (e.g., RRC signaling), and the configured time domain resource sets are shown in Table 2. Then, the base station can indicate combinations of multiple beam indices and time domain resource sets through dynamic signaling (e.g., DCI), as shown in Figure 6. Using Scheme 2, multiple beam indices in a time domain resource set can be effectively indicated, saving signaling overhead and reducing processing delays caused by multiple signaling.

[0084] [Table 2]

[0085] However, when using Scheme 2, due to signaling load limitations, it is not possible for all time domain resource sets to be traversed, and some time domain resources in multiple time domain resource sets may overlap, and multiple beam indices may be associated with these time domain resources, resulting in collision of beam instructions, disruption of relay node operation, increased power consumption of relay nodes, increased signaling overhead, increased transmission delay, reduced accuracy of beam instructions, or reduced transmission quality of the system. An example will be described with reference to FIG. 7.

[0086] As shown in Figure 7, beam 0 corresponds to the "off" state, and if the dynamic signaling includes beam instruction combination 1 {beam 0, TRS0} and beam instruction combination 2 {beam 1, TRS1}, TRS0 includes time domain resource TR2, and TRS1 also includes TR2, so that the relay node does not know whether to perform the "off" operation on time domain resource TR2 or to perform transmission using beam 1.

[0087] To address the above problem, a node having relay function according to an embodiment of the present application can determine that the second module of the first node is in an off state or determine a first beam for transmitting or receiving a radio signal based on at least one of the at least two beam information items that collide in the first time domain resource, thereby achieving one or more of the following objectives: solving the beam indication collision problem, saving power consumption of the relay node, saving signaling overhead, reducing transmission delay, improving the accuracy of beam indication, and improving the transmission quality of the system.

[0231] For ease of understanding, the following describes how to determine the first state of the first time domain resource of the second module with reference to a specific example, so as not to disrupt the operation of the first time domain resource of the first node. In the following embodiment, the NCR corresponds to the first node described above, the beam instruction combination corresponds to the first information described above, the beam index corresponds to the beam information described above, and the gNB corresponds to the second node described above. Note that the following example is provided to help those skilled in the art understand the embodiments of the present application and is not intended to limit the embodiments of the present application to the specific numerical values ​​or specific scenarios exemplified. It is apparent that those skilled in the art can make various equivalent modifications or variations within the scope of the embodiments of the present application according to the specific example provided.

[0232] Note that in the following examples, solid lines indicate operations that the second module needs to perform on the first time domain resource, and dashed lines indicate operations that the second module does not need to perform on the first time domain resource.

[0233] Example 1: At least one of the at least two beam information is the first beam information.

[0234] When at least two beam instruction combinations from the same signaling or different signaling collide in the first time domain resource, if one of the beam indexes includes beam0 (i.e., used to instruct the second module to be in an off state), the NCR determines that the second module is in an off state in the first time domain resource (i.e., performs an off operation in the first time domain resource) to avoid causing unnecessary interference.

[0235] As shown in Figure 9, beam pointing combination 1 and beam pointing combination 2 collide at TR2, and the beam index corresponding to beam pointing combination 1 is beam0, so the NCR can determine that the second module is in an off state at TR2.

[0236] In the example of Figure 9, beam0 is shown as a solid line and is used to instruct the second module to be in an off state in the first time domain resource, and beam1 is shown as a dashed line and is used to instruct the second module to perform transmission without using beam1 in the first time domain resource.

[0237] Example 2: Second beam information is used to determine the first beam, and the second beam information is selected randomly.

[0238] In Example 2, the NCR only supports single beam transmission.

[0239] When at least two beam instruction combinations from the same signaling or different signaling collide in the first time domain resource, if the two beam instruction combinations each indicate a different beam index in the first time domain resource, the NCR randomly selects one beam index from the indicated beam indexes in the first time domain resource and performs transmission based on the beam corresponding to the selected beam index.

[0240] As shown in Figure 10, beam instruction combination 1 and beam instruction combination 2 collide in TR2, beam instruction combination 1 instructs TR2 to perform transmission using beam1, and beam instruction combination 2 instructs TR2 to perform transmission using beam2, and NCR randomly selects beam2 as the first beam and performs transmission in TR2 based on the beam corresponding to beam2.

[0241] In the example of Figure 10, beam2 is shown as a solid line and is used to instruct the second module to perform transmission using beam2 in the first time domain resource, and beam1 is shown as a dashed line and is used to instruct the second module to perform transmission without using beam1 in the first time domain resource.

[0242] Example 3: Second beam information is used to determine the first beam, and the second beam information is selected based on the position of the beam information.

[0243] In Example 3, the NCR supports only single beam transmission.

[0244] When at least two beam designation combinations from the same signaling or different signaling collide in the first time domain resource, if the two beam designation combinations designate different beam indices in the first time domain resource, the NCR determines one beam index in the first time domain resource based on the positions in the multiple domains of the first information of the beam indices corresponding to the at least two beam designation combinations, and performs transmission based on the beam corresponding to the selected beam index. For example, in the first time domain resource, the NCR can select a beam index whose position in the multiple domains of the first information is earlier from the designated at least two beam designation combinations, as the first beam.

[0245] As shown in Figure 11, beam designation combination 1 and beam designation combination 2 collide in TR2, beam designation combination 1 instructs TR2 to perform transmission using beam1, and beam designation combination 2 instructs TR2 to perform transmission using beam2, and the NCR selects a beam index (beam1) that is located in the front position in the multiple domains of the first information from the designated beam designation combination 1 and beam designation combination 2 as the first beam, and performs transmission in TR2 based on the beam corresponding to beam1. The positions of beam designation combination 1 and beam designation combination 2 in the multiple domains of the first information can be seen in Figure 12. In one embodiment, the gNB may arrange the recommended beam designation combination in the front position in the multiple domains of the first information.

[0246] In the example of Figure 11, beam1 is shown by a solid line and is used to instruct the second module to perform transmission using beam1 in the first time domain resource, and beam2 is shown by a dashed line and is used to instruct the second module to perform transmission without using beam2 in the first time domain resource.

[0247] Example 4: All beam information of at least two beam information is used to determine a first beam.

[0248] In Example 4, the NCR includes multiple radio frequency chains and can support multi-beam transmission.

[0249] When at least two beam instruction combinations from the same signaling or different signaling collide in the first time domain resource, if the two beam instruction combinations indicate different beam indices in the first time domain resource, the NCR takes the union of the multiple beam indices indicated by the at least two beam instruction combinations in the first time domain resource, and performs multi-beam transmission based on the beams corresponding to all selected beam indices, for example, performs multi-beam transmission based on the beams corresponding to all selected beam indices in the A-link.

[0250] As shown in Figure 13, beam instruction combination 1 and beam instruction combination 2 collide in TR2, beam instruction combination 1 instructs to perform transmission using beam 1 in TR2, beam instruction combination 2 instructs to perform transmission using beam 2 in TR2, and NCR selects beams corresponding to beam 1 and beam 2 to perform multi-beam transmission in TR2.

[0251] In the example of Figure 13, beam1 and beam2 are both shown with solid lines and are used by the second module to instruct the second module to perform multi-beam transmission using beam1 and beam2 in the first time domain resource.

[0300] 18 is a schematic diagram of hardware modules of a communication device according to an embodiment of the present application. Specifically, FIG. 18 shows a block diagram of a first communication device 450 and a second communication device 410 communicating with each other in an access network.

[0301] 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 .

[0302] 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 .

[0303] In transmission from the second communication device 410 to the first communication device 450, upper layer data packets from the core network or from a data source 477 are provided to a controller / processor 475 in the second communication device 410. The core network and data source 477 represent all protocol layers above the L2 layer. The controller / processor 475 implements L2 layer functionality. In 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 logic and transmission 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 multi-antenna transmit processor 471 implement various signal processing functions for the L1 layer (i.e., the physical layer). The transmit processor 416 performs encoding and interleaving to facilitate forward error correction (FEC) and signal cluster mapping based on various modulation formats (e.g., binary phase shift keying, quadrature phase shift keying, M-phase shift keying, M-quadrature amplitude modulation) at the second communication device 410. The multi-antenna transmit processor 471 performs digital spatial precoding, including codebook-based precoding and non-codebook-based precoding, and beamforming on the encoded and modulated symbols to generate one or more spatial streams. The transmit processor 416 then maps each spatial stream to subcarriers, multiplexes them with reference signals (e.g., pilots) in the time and / or frequency domains, and then generates a physical channel carrying a time-domain multi-carrier symbol stream using an inverse fast Fourier transform. The multi-antenna transmit processor 471 then performs transmit analog precoding / beamforming operations 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 an RF stream, which is then provided to a different antenna 420.

[0304] During transmission from the second communication device 410 to the first communication device 450, each receiver 454 in the first communication device 450 receives a signal via its corresponding antenna 452. Each receiver 454 recovers the information modulated onto the RF carrier and converts the RF stream into a baseband multi-carrier symbol stream, which is then provided to a receive processor 456. The receive processor 456 and the multi-antenna receive processor 458 perform various signal processing functions in the L1 layer. The multi-antenna receive processor 458 performs receive analog precoding / beamforming operations on the baseband multi-carrier symbol stream from the receiver 454. The receive processor 456 uses a fast Fourier transform to convert the baseband multi-carrier symbol stream after the receive analog precoding / beamforming operation from the time domain to the frequency domain. In the frequency domain, the physical layer data signal and reference signal are demultiplexed by the receive processor 456, the reference signal is used for channel estimation, and the data signal undergoes multi-antenna detection in the multi-antenna receive processor 458, after which any spatial streams destined for the first communication device 450 are recovered. The symbols of each spatial stream are demodulated and recovered in the receive processor 456 to generate soft decisions. The receive processor 456 then decodes and deinterleaves the soft decisions to recover the upper layer data and control signals transmitted from the second communication device 410 over the physical channel. The upper layer data and control signals are then 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 also be referred to as a computer-readable medium. During transmission from the second communication device 410 to the first communication device 450, the controller / processor 459 recovers the upper layer data packets from the second communication device 410 by providing multiplexing between transport and logical channels, packet reassembly, decoding, header decompression, and control signal processing. The upper layer data packets are then provided to all protocol layers above the L2 layer. Various control signals may be provided to L3 for L3 processing.

[0305] In a transmission from the first communication device 450 to the second communication device 410, the first communication device 450 uses a data source 467 to provide upper layer data packets to a controller / processor 459. The data source 467 represents all protocol layers above the L2 layer. Similar to the transmission function of 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 performs header compression, encryption, packet division, reordering, logic and multiplexing between transmission channels, and performs L2 layer functions used for the user plane and 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, and the multi-antenna transmit processor 457 performs digital multi-antenna spatial precoding and beamforming processing, including codebook-based precoding and non-codebook-based precoding. The transmit processor 468 then modulates the generated spatial streams into multi-carrier / single-carrier symbol streams, which are then provided to different antennas 452 by transmitters 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 an RF symbol stream, which is then provided to the antenna 452.

[0306] In a transmission from the first communication device 450 to the second communication device 410, the function of the second communication device 410 is similar to the receiving function of 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 an RF signal via its corresponding antenna 420, converts the received RF signal to a baseband signal, and provides the baseband signal to a multi-antenna receive processor 472 and a receive processor 470. The receive processor 470 and the multi-antenna receive processor 472 collectively perform the functions of the L1 layer. A controller / processor 475 performs the functions of the L2 layer. The controller / processor 475 may be associated with a memory 476 that stores program codes and data. The memory 476 may also be referred to as a computer-readable medium. In transmission from the first communication device 450 to the second communication device 410, the controller / processor 475 provides multiplexing between transport and logic channels, packet reassembly, decoding, header decompression, and control signal processing to recover 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 be provided to the core network or L3 for use in L3 processing.
